heartworm prevalence by zip code

2014;11:325670. Urbanization is one context in which vector assemblage and diversity vary, potentially with implications for heartworm disease transmission. Evans MV, Dallas TA, Han BA, Murdock CC, Drake JM. At least in the context of suburban areas, mosquito communities do not recover from these diversity losses after the initial land-use change; diversity decreases as neighborhoods age, resulting in the lowest diversity mosquito assemblages in the most established suburban areas [10]. 2006;135:30314. On one hand, heartworms maintain a stubborn hold in the U.S., with the southeastern U.S. leading the nation in incidence. columbiae, Cx. DGE-1746939. 2022 Jul 11;107(2):231-44. doi: 10.4269/ajtmh.21-0167. PubMed Central albopictus, versus in natural areas, where bites come from a more diverse mosquito assemblage in which a given species may or may not be a competent D. immitis vector. May 16, 2019, 6:04 AM. Suburban areas had lower within-mosquito heartworm prevalence and lower likelihood of heartworm-positive mosquitoes than did undeveloped field sites, although no differences were seen between suburban and undeveloped wooded sites. Socio-ecological mechanisms supporting high densities of Aedes albopictus (Diptera: Culicidae) in Baltimore, MD. & Reiskind, M.H. However, since mosquitoes are responsible for transferring the parasite . ProHeart 12, a moxidectin extended-release injectable formulation for prevention of heartworm (Dirofilaria immitis) disease in dogs in the USA for 12 months. To minimize the risk of sample contamination, qPCR was performed at a dedicated workstation that was separate from that utilized for DNA extraction. Relative suitability of Aedes albopictus and Aedes aegypti in North Carolina to support development of Dirofilaria immitis. Almost 6000 veterinary practices and shelters participated in the AHS survey in early 2020. 2019;14:e0215485. Join the leading association on Heartworm education and prevention today! We stored the extracted DNA at 20C until the time of further analysis. In the present study, we sought to determine the relationship between mosquito diversity and D. immitis prevalence in domestic dogs within the suburban setting. We found that the best model to predict heartworm prevalence within dogs at the zip code level is one that includes both mosquito ShannonWiener diversity and household income. Given the lower probability of D. immitis-positive mosquitoes noted in suburban areas, our focus on sampling mosquitoes predominantly in suburbia could have resulted in lower overall within-mosquito prevalence rates than what has been reported in other studies sampling in more rural landscapes (e.g. All zip codes in Wake County had some level of heartworm infection, but zip codes where mosquitoes were not sampled were omitted from visualization (denoted NA) for clarity. Parasit Vectors. We maximized the likelihood function: where \(y_{i\,j}\) is the binary response of whether pool \(j\) in habitat \(i\) was positive for D. immitis, \(n_{i\,j}\) is the number of mosquitoes in pool \(j\) from habitat \(i\), and \(p_{i}\) is the probability that an individual mosquito in habitat \(i\) is positive for D. immitis. In terms of percent D. immitis-positive mosquito pools, Ae. When investigating correlations of mosquito diversity metrics at the zip code level to within-host D. immitis prevalence, we detected significant positive relationships for evenness (F(1, 16)=4.881, P=0.042, R2=0.234) and ShannonWiener diversity (F(1, 16)=5.464, P=0.033, R2=0.255) (Fig. Spence Beaulieu MR, Hopperstad K, Dunn RR, Reiskind MH. J Med Entomol. Conclusions: Zip codes where clinics have obtained at least one positive feline heartworm antibody result. Centro Automotivo Pneus&Pneus heartworm prevalence by zip code We created categories of neighborhood ages to ensure that neighborhoods of various ages were being sampled: developed before 1993, between 19932002, between 20032007, between 20082012 and from 2013 to present. However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. Mosquitoes of the southeastern United States. Figure 1. However, there are numerous examples of disease systems in which an assembly of vector species are responsible for pathogen transmission (e.g. PooledInfRate: a Microsoft Office Excel add-in to compute prevalence estimates from pooled samples. Examining landscape factors influencing relative distribution of mosquito genera and frequency of virus infection. J Vector Ecol. A similar study of D. immitis prevalence within mosquitoes in an urbanized area of Oklahoma, USA found that urban sites had significantly higher heartworm infection rates than rural sites and implicated Ae. PubMed To disentangle the effects of mosquito diversity and mosquito abundance, we also calculated the average abundance within a zip code per site per trap-night and performed a linear regression comparing log average mosquito abundance to within-host heartworm prevalence. Early registration for September 8-11 th conference in New Orleans ends July 15th April is National Heartworm Awareness Month! We calculated the bias corrected maximum likelihood estimate (MLE) for point estimation of the infection rate of each heartworm-positive mosquito species using PooledInfRate add-in software for Excel [34]. pipiens, Anopheles quadrimaculatus, Culex erraticus and Ae. Heartworm prevalence is, overall, low in Canada, with endemic transmission occurring seasonally only in regions of southern British Columbia, Manitoba, Ontario, Quebec, and New Brunswick. Linthicum KJ, Britch SC, Anyamba A. Accessibility canadensis and An. Annu Rev Entomol. There is effective preventative medication that protects dogs from becoming infected with D. immitis, but these medications are by prescription only, requiring not only the cost of the medication but also the cost of routine veterinary care, presenting a financial barrier for some pet owners. As expected, people of higher socioeconomic status reported greater use of preventative medications, resulting in lower levels of vector-borne pathogens, including D. immitis [22]. columbiae appears to be a significant contributor to heartworm transmission in suburban Wake County, as it was the only species in the current study to have >1% D. immitis-positive pools in suburban neighborhoods. Percent parous mosquitoes and percent, Comparison of within-mosquito heartworm prevalence by land-use type. Each of these sites contained some wooded habitat and some field or pasture habitat, allowing us to conveniently sample mosquitoes in these two distinct habitat types. Eight mosquito species showed evidence of D. immitis infection, with Aedes canadensis having the highest percentage positive pools at 7.7% and the highest MLE infection rate at 29.75 per 1000 individuals (95% CI: 1.79136), followed by Anopheles crucians and Psorophora columbiae both with approximately 2.9% positive pools and MLEs of 26.23/1000 (95% CI: 1.52119.72) and 11.85/1000 (95% CI: 3.8928.05), respectively (Table1, Fig. Studies on the vector competence of Ae. doi: 10.1146/annurev.ento.54.110807.090626. Trends Parasitol. 1961;54:44851. We then tested the null hypothesis that \(\sum p_{i} = p\) using a likelihood ratio test, utilizing the Holm method to correct for multiple comparisons when identifying which land-uses differed in their probabilities. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. Mosquito diversity and dog heartworm prevalence in suburban areas, $$L\left( {p_{i} } \right) = \left( {\left( {1 - p_{i} } \right)^{{n_{i\,j} }} } \right)^{{\left( {1 - y_{i\,j} } \right)}} *\left( {1 - \left( {1 - p_{i} } \right)^{{n_{i\,j} }} } \right)^{{y_{i\,j} }}$$, https://doi.org/10.1186/s13071-019-3874-0, https://doi.org/10.6084/m9.figshare.9339302.v1, https://www.heartwormsociety.org/veterinary-resources/incidence-maps, http://www.cdc.gov/westnile/resourcepages/mosqSurvSoft.html/, https://github.com/arilamstein/choroplethrZip, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. While acknowledging these important caveats, the AHS hypothesized a conservative estimate of heartworm prevalence via the following calculations: Figure 2. Urban and suburban areas throughout much of the USA are dominated by the peridomestic Aedes albopictus, which is a competent vector of D. immitis [20]. Heartworm indicators are found in the blood of 80%-90% of dogs. Data on file. quadrimaculatus) are known to be competent heartworm vectors [20]. All 50 states have had confirmed cases of heartworm since the disease's discovery back in 1856. Steiger DBM, Ritchie SA, Laurance SG. He has held various roles with Boehringer Ingelheim since leaving private mixed-animal practice in 1993. Distinguishing nulliparous from parous female Culex tarsalis by examination of the ovarian tracheation. Our results suggest that decreases in mosquito diversity due to urbanization lead to decreases in dog heartworm prevalence. The zip code of the surrendered or stray dog was noted at shelter intake, allowing analysis of trends at the scale of zip code level or larger. All other mosquito species had less than 1.4% D. immitis-positive pools and MLEs of less than 7.1/1000.

HHS Vulnerability Disclosure, Help Taken together with the present findings, this suggests that suburban development is decreasing mosquito diversity, and that the resultant decreased mosquito diversity is linked with lower heartworm disease prevalence. Parasitology. Top Companion Anim Med. Urbanization is occurring rapidly on a global scale and is altering mosquito communities, creating assemblages that are characteristically less diverse. Our findings contribute to an understanding of the local transmission dynamics of the prevalent and devastating dog heartworm parasite in suburban areas of North Carolina, USA. We found significant differences in within-mosquito D. immitis prevalence among land-use types (KruskalWallis test: 2=8.555, df=2, P=0.014). Parasites Vectors 12, 369 (2019). Sinka ME, Bangs MJ, Manguin S, Coetzee M, Mbogo CM, Hemingway J, et al. Please enable it to take advantage of the complete set of features! The datasets analyzed during the present study are available in the Figshare repository: https://doi.org/10.6084/m9.figshare.9339302.v1. [39]). However, decreases in mosquito diversity after human-driven land-use change could be detrimental when considering other disease systems of concern that are vectored by few mosquito species, such as dengue, chikungunya and Zika with Ae. and canine heartworm (Dirofilaria immitis) in the mosquitoes of Tennessee. Within the landscape of North Carolina, this equates to less heartworm disease expected within the host in suburban areas as a function of urbanization-induced mosquito diversity losses. J Parasitol. Ledesma N, Harrington L. Mosquito vectors of dog heartworm in the United States: vector status and factors influencing transmission efficiency. Field sites had greater D. immitis prevalence than did suburban sites (Dunns test: Z=2.925, P=0.010), but prevalence at wooded sites did not differ from that at suburban sites (Dunns test: Z=0.630, P=1.0) (Fig. doi: 10.7554/eLife.22053. The Companion Animal Parasite Council recommends pets be tested annually and protected year-round 7 Essential Reasons Every Cat Needs an Annual Vet Exam. Clipboard, Search History, and several other advanced features are temporarily unavailable. Importantly, the parasite is naturally vectored by at least 25 mosquito species in the USA [20] and even greater numbers of species worldwide with varying vectorial capacities. Accessed 30 Jun 2018. Thongsripong P, Green A, Kittayapong P, Kapan D, Wilcox B, Bennett S. Mosquito vector diversity across habitats in central Thailand endemic for dengue and other arthropod-borne diseases. Similar to our results with within-mosquito prevalence, using the presence or absence of D. immitis within mosquitoes, we did not see a significant relationship to within-host prevalence by zip code (t(8.22)=0.941, P=0.374). Previous work with malaria has demonstrated a similar positive relationship between mosquito species richness and disease prevalence [5], suggesting that mosquito diversity losses being linked with decreased disease transmission could be applicable to a variety of multi-vectored diseases. See code. While it is possible to use the survey data to make rough projections regarding heartworm prevalence, it is impossible to know exactly how many pets in the U.S. are infected with heartworms at any given time. Given that anthropogenic land-use change alters the diversity and composition of mosquito assemblages and is occurring rapidly worldwide, greater understanding of the role of vector diversity in multi-vectored diseases is critical and will have global impacts. Using zip code level data acquired from dogs in a local shelter, we performed linear regressions of within-host heartworm prevalence by within-mosquito heartworm prevalence as well as by three mosquito diversity measures. Make an appointment. Paola Domnguez-Lpez has always been passionate about animals. KruskalWallis test was chosen due to the non-normal nature of the data, and Dunns test for multiple comparisons with Bonferroni correction was utilized to identify which land-uses differed in their heartworm prevalence. Top Companion Anim Med. 1):607. Vet Parasitol. Zip codes where clinics have obtained at least one positive feline heartworm antigen result. Unable to load your collection due to an error, Unable to load your delegates due to an error, Species-level heartworm prevalence by land-use type. With so many known heartworm vectors spanning across multiple genera, the apparent lack of seasonality coupled with a positive correlation with parity could be due to vector mosquitoes having different phenologies, making heartworm transmission potential a nearly constant risk throughout the warmer months in North Carolina. We also sampled at 6 additional smaller parcels of land composed of undeveloped woodlots and 5 additional smaller parcels of land composed of undeveloped fields. official website and that any information you provide is encrypted The effect of urbanization is well known for certain mosquito species of interest, particularly the container-breeding Aedes [7, 8], but has only recently been examined in the context of effects on mosquito species assemblages. Our previous work has shown that mosquito rarefied richness, evenness and ShannonWiener diversity is decreased in established suburban neighborhoods when compared with undeveloped natural areas [10]. Interestingly, our previous work in Wake County did not find any effect of socioeconomic status on mosquito diversity measures [10], so the effect of socioeconomic status detected in the present study is likely due to its impact on host-level factors. FOIA Large dog relinquishment to two municipal facilities in New York City and Washington, DC: identifying targets for intervention. Thatsalot. 12 ISSN: 1756-3305 We calculated heartworm prevalence within dogs by zip code in Wake County. [10]. 2009;54:469487. As all sample sequences were identical based on a reference alignment, one sample sequence was used in the MegaBLAST algorithm from the NCBI Nucleotides BLAST suite, returning a positive match to a portion of D. immitis COI with 100% homology (GenBank: AJ537512.1) [33].

Pet relocation. Download : Download full-size image Fig. Kardos EH, Bellamy RE. albopictus have greater dog heartworm prevalence. According to theAmerican Heartworm Society, Mississippi, Louisiana, Arkansas, Texas and Tennessee are the top five worst states when it comes to heartworm diagnosis, in that order. According to the AHS survey, 82% reported that they follow the AHS guidelines on prevention, diagnosis, and treatment of heartworm disease, while more than half of practitioners utilize resources on the AHS website. While we did not detect any differences in heartworm prevalence within mosquitoes based on neighborhood age, it could still be affecting prevalence within the host indirectly by decreasing mosquito diversity, as mosquito diversity metrics decrease as suburban neighborhoods age [10]. High prevalence of canine heartworm, Dirofilaria immitis, in pet dogs in south Texas, USA, with evidence of Aedes aegypti mosquitoes contributing to transmission. -, Fuller DO, Alimi T, Herrera S, Beier JC, Quiones ML. To help reduce the transmission of heartworm disease in animals, the AHS partnered with the Association of Shelter Veterinarians (ASV) in 2018 to develop recommendations for the safe transport of heartworm-positive pets (, Compliance is the leading factor associated with downward trends in heartworm incidence. 2015;51:6649. 2022 Nov 3;15(1):407. doi: 10.1186/s13071-022-05514-1. It is believed this change was triggered by drier-than-normal conditions in the western U.S. in 2017 and 2018 that led to lower mosquito populations. 2003;40:78594. Species-level heartworm prevalence by land-use, Species-level heartworm prevalence by land-use type. 2013;29:4608. Due to local climate and rainfall, some areas of the country have mosquitoes all year round, so the risk for dogs to contract heartworms is definitely higher than for dogs in hotter, drier areas of the Southwest. dogs spending more time outdoors) or through changes in vector assemblages. https://factfinder.census.gov/. No state in the U.S. is heartworm-free, according to the AHS survey. Every three years, the American Heartworm Society (AHS) gathers data on heartworm testing to understand the impact heartworm is having nationwide, as well as in specific regions. PubMed Percent parous mosquitoes and percent Dirofilaria immitis-positive mosquito pools were compared for data from the 2015 trapping season. We performed real time quantitative polymerase chain reaction (qPCR) to assess for presence or absence of D. immitis DNA within the previously extracted and quantified mosquito pools. Part of 6. J Med Entomol. We identified all mosquitoes to species using published dichotomous keys [29, 30]. Methods: Springer Nature. COLLECTIF CITOYEN EN CHARTREUSE. Qui, quoi, comment ? We also found that the probability of an individual mosquito being positive for D. immitis differed between land-uses (LRT statistic =6.40, P=0.041). volume13, Articlenumber:12 (2020) As with the KruskalWallis test, we again performed this test for land-use type both with and without neighborhood age categories as levels within the broader suburban category. All pools that were positive for D. immitis DNA were those of mosquito species known to be competent heartworm vectors [20], so we assume that any positive mosquito pool represents potential transmission. Online ahead of print. An official website of the United States government. Zika virus. Europe PMC. Dogs at higher risk of contracting heartworm disease from mosquitoes in OC, officials say. The qPCR procedure consisted of a denaturation step at 95C for 30s, followed by 40 cycles of denaturation at 95C for 5s, annealing at 60C for 15s and extension at 72C for 10seconds. We also determined the best predictor of host-level prevalence among models including within-mosquito infection, mosquito diversity and abundance, and socioeconomic status as variables. Briefly, we identified suburban neighborhoods of various ages throughout Wake County, NC, USA using Google Earth historical images [27], taking the year of first evidence of construction as the year the neighborhood was built. Within the canine host, the adult heartworm resides in the pulmonary arteries and the heart, causing respiratory distress and eventually congestive heart failure [17]. The American Heartworm Society (AHS) estimates that only 55% of dogs in the U.S. are currently on a heartworm preventive. Rounding out the top 10 states were Texas, Tennessee, Georgia, North Carolina, and Oklahoma. 2017 Feb 20;10(1):94. doi: 10.1186/s13071-017-2015-x. The earliest D. immitis-positive pool of mosquitoes was collected during the first week of June, which coincided with the beginning of our trapping season, and the latest D. immitis-positive pool of mosquitoes was collected during the third week of October. Since sample sizes varied among species, the number of positive pools and the total number of pools tested per species are provided above each bar, Relationship between mosquito parity and within-mosquito heartworm prevalence. A total of 7625 dogs were tested for heartworm and designated a zip code upon shelter intake. Heartworm Lifecycle. PubMed As the percentage of mosquitoes in the area that have previously laid eggs (and therefore previously taken a blood meal) increases, D. immitis presence in mosquitoes also increases, reaffirming that older mosquitoes are the most dangerous from a disease transmission standpoint due to their greater probability of prior pathogen exposure. Urban and suburban development is predicted to increase by greater than 100% over the next 50years in the southeastern USA [48], in line with global trends of increasing urbanization.

Since parity data for mosquitoes were collected only in 2015, we assessed for correlation of parous mosquitoes with heartworm-positive pools in 2015. 4324 E MEARENTE S PROVO UT 84606-8099. A significant positive correlation was noted between within-host heartworm prevalence and (. Because the goal was to determine simple presence or absence of D. immitis within the mosquito pools, CFX Maestro software (Bio-Rad Laboratories, Hercules, CA, USA) was used to visually assess for DNA amplification and therefore presence of D. immitis DNA within the sample prior to 30 cycles. These data contained the results of the heartworm test performed at the time of intake as well as the zip code of the prior owner or location of capture. Mosquitoes show habitat fidelity at a much finer scale of less than 100m [28], leading to a separation of geographical scale between mosquito-level factors and host-level factors that could be obscuring some trends. Letters above the bars denote significant differences. [1,2,3,4]). However, when analyzing the 2015 data, percent heartworm-positive mosquito pools was positively correlated with percent parous mosquitoes across the trapping season (Fig. Using zip code level data acquired from dogs in a local shelter, we performed linear regressions of within-host heartworm prevalence by within-mosquito heartworm prevalence as well as by three mosquito diversity measures. At each of the suburban and undeveloped sites, we sampled overnight with CDC light traps (JW Hock Co., Gainesville, FL, USA) baited with 1kg of dry ice (solid CO2). J Med Entomol. Although the response is likely different for diseases transmitted by one or few species, mosquito diversity losses leading to decreased transmission could be generalizable to other pathogens with multiple vectors.
