heartworm prevalence by zip code

-. CAS However, these species only had positive pools detected in undeveloped natural areas. Fully mature adults at 6.5 months after infection reach lengths of 15-18 cm (5-6 in) for males and 25-30 cm (10-12 in) for females. Zip code-level data used for comparative analyses, including heartworm prevalence within the canine host, can be found in "byzip." Data details are included in the read me file. A significant positive correlation was noted between within-host heartworm prevalence and (a) mosquito evenness (F(1, 16)=4.881, P=0.042, R2=0.234) as well as (b) mosquito ShannonWiener diversity (F(1, 16)=5.464, P=0.033, R2=0.255). Ledesma N, Harrington L. Mosquito vectors of dog heartworm in the United States: vector status and factors influencing transmission efficiency. Heartworm disease is a serious disease that results in severe lung disease, heart failure, other organ damage, and death in pets, mainly dogs, cats, and ferrets. 4a). Multistate Hatch Project MS-1443/1943/USDA, Sinka ME, Bangs MJ, Manguin S, Coetzee M, Mbogo CM, Hemingway J, et al. vexans, Cx. 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]. 2022 Sep 7;13(9):814. doi: 10.3390/insects13090814. Wild host densities are not assessed in this study, but could play an important role in the heartworm transmission dynamics for domestic dogs, particularly if wild hosts that typically serve as primary D. immitis reservoirs are excluded from highly urbanized areas. 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. Studies investigating socioeconomic gradients have variably shown greater mosquito prevalence in lower income neighborhoods [23, 24] and in higher income neighborhoods [25], as well as no effect on mosquito densities [26]. Sci Rep. 2016;6:29002. Johnson MF, Gmez A, Pinedo-Vasquez M. Land use and mosquito diversity in the Peruvian Amazon. First Name Last Name. See this image and copyright information in PMC. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. See code. 364 S 300 E PROVO UT 84606-4706. American FactFinder. Accessed 12 Jun 2019. Since then, the AHS Heartworm Incidence Survey has been conducted every 3 years, using heartworm testing data submitted by veterinary practices, reference laboratories, and animal shelters. Statistical analyses The Invasive Mosquitoes of Canada: An Entomological, Medical, and Veterinary Review. 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. We then calculated proportion heartworm-positive mosquito pools by zip code so that the two datasets were at comparable scales. LaDeau S, Leisnham P, Biehler D, Bodner D. Higher mosquito production in low-income neighborhoods of Baltimore and Washington, DC: understanding ecological drivers and mosquito-borne disease risk in temperate cities. 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). albopictus [46, 47]. We homogenized the mosquitoes using sterilized pestles in sterilized microcentrifuge tubes and followed modified versions of the standard kit protocols for DNA extraction (full extraction protocols are presented in Additional file 1: Text S1). The goal of the column is to communicate practical and timely information on prevention, diagnosis, and treatment of heartworm disease, as well as highlight current topics related to heartworm research and findings in veterinary medicine. Google Scholar. Address. Address example. Ae. This site needs JavaScript to work properly. Although vector biodiversity is our primary interest, another potentially important contributor to dog heartworm disease risk is socioeconomic status. albopictus have greater dog heartworm prevalence. Yet throughout the trapping season, percent D. immitis-positive pools was positively correlated with mosquito parity data. We trapped host-seeking mosquitoes in undeveloped areas and neighborhoods of different ages in Wake County, North Carolina, USA, analyzing captured mosquitoes for heartworm DNA. 2023 BioMed Central Ltd unless otherwise stated. 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/.

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. Int J Environ Res Public Health. The mosquitoes implicated as heartworm vectors within suburban areas in this study were Ps. Studies on the vector competence of Ae. PooledInfRate: a Microsoft Office Excel add-in to compute prevalence estimates from pooled samples. 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. We stored the extracted DNA at 20C until the time of further analysis. https://doi.org/10.1186/s13071-019-3874-0, DOI: https://doi.org/10.1186/s13071-019-3874-0. We analyzed entire mosquito bodies for the presence of D. immitis DNA; because of this, we were unable to distinguish between infected and infectious mosquitoes. 2003;40:78594. Mosquitoes used for analysis in this study were previously sampled and the effects of suburban development on mosquito diversity were previously assessed in Spence Beaulieu et al. 2010;3:117. Bethesda, MD 20894, Web Policies On one hand, heartworms maintain a stubborn hold in the U.S., with the southeastern U.S. leading the nation in incidence. 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. He has authored or co-authored 35 peer-reviewed papers, 34 scientific papers, and co-authored a best-selling companion animal parasitology atlas. FOIA Zika virus. At the wooded and field sites, traps were placed at least 100m away from any habitat edge, again consistent with previous findings of mosquito habitat fidelity [28]. Parasites & Vectors Neighborhood age was not a significant factor, as KruskalWallis test was not significant when incorporating neighborhood age categories. Annu Rev Entomol. Trivellone V, Cao Y, Blackshear M, Kim CH, Stone C. Front Public Health. albopictus as the areas primary vector [21]. Mississippi and Louisiana lead the country in heartworm infection rates The five states with the highest incidence of heartworm were Mississippi, Louisiana, South Carolina, Arkansas, and Alabama. Mosquito species distribution across urban, suburban, and semi-rural residences in San Antonio. Sinka ME, Bangs MJ, Manguin S, Coetzee M, Mbogo CM, Hemingway J, et al. 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. Careers. Additionally, lower socioeconomic status could increase disease risk via increased vector exposure, either through behavioral factors (e.g. Because of their inability to be infectious for D. immitis, we excluded males and nulliparous females from further analysis. & Reiskind, M.H. Part of The second test included neighborhood age categories separately, resulting in seven total treatment levels (wood, field and five neighborhood age categories as previously described). columbiae, Cx. [39]). Heartworm incidence in the continental U.S. and Hawaii based on the 2016 AHS Heartworm Incidence Survey. However, since mosquitoes are responsible for transferring the parasite . Dog heartworm is considered endemic in the contiguous USA, with highest prevalence in the southeastern USA [19]. Percent positive pools by species is presented, with bars color-coded to denote the land-use type where the positive pool originated. Data-driven identification of potential Zika virus vectors. While acknowledging these important caveats, the AHS hypothesized a conservative estimate of heartworm prevalence via the following calculations: Figure 2. These factors and more were cited in a recent survey of U.S. veterinarians as factors contributing to the rise and fall of heartworm incidence in their practice areas. Modified DNA extraction protocols used with both the DNeasy Blood and Tissue Kit (Qiagen, Venlo, Netherlands) and the ZR Genomic DNA-Tissue MiniPrep (Zymo Research, Irvine, CA, USA).

The datasets analyzed during the present study are available in the Figshare repository: https://doi.org/10.6084/m9.figshare.9339302.v1. Cats are known to have a penchant for biting and scratching, but even the most fierce feline can Pets are beloved members of many families. 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. Using an estimate of client base and combining these data with dog numbers from the American Veterinary Medical Association, it is possible to generate a rough estimate of heartworm cases for the U.S. and, more importantly, to track trends. statement and As dog heartworm disease is vectored by an assemblage of mosquito species, changes in mosquito diversity will likely affect disease prevalence. To view a copy of this licence, visit http://creativecommons.org/licenses/by/4.0/. Urbanization is occurring rapidly on a global scale and is altering mosquito communities, creating assemblages that are characteristically less diverse. We also determined the best predictor of host-level prevalence among models including within-mosquito infection, mosquito . The Invisible Threat to Your Pet: How to Prevent Heartworm Disease. While the relationship with rarefied richness was not significant (F(1, 16)=4.342, P=0.054, R2=0.213), there was a similar positive trend (Fig. All 50 states have had confirmed cases of heartworm since the diseases discovery back in 1856. Among models including all combinations of our tested variables (presence or absence of heartworm-positive mosquito pools, proportion heartworm-positive mosquito pools, rarefied richness, evenness, ShannonWiener diversity, mosquito abundance and median household income), selection revealed that the top model set (all models with AIC<2) included two models: (i) mosquito ShannonWiener diversity and median household income (AIC=23.95, residual df=15, AIC=0); and (ii) mosquito ShannonWiener diversity, mosquito rarefied richness and median household income (AIC=25.45, residual df=14, AIC=1.5). Thatsalot. It was revealed the top 5 states for heartworm incidence were Mississippi, Louisiana, South Carolina, Arkansas, and Alabamaall states that have been in the top 10 states since the AHS began tracking incidence data in 2002. Park AW, Cleveland CA, Dallas TA, Corn JL. Conclusions: Identification and geographical distribution of the mosquitos of North America, north of Mexico. Among veterinarians who saw cases drop over the past 3 years, the top 2 reasons they gave were (1), Veterinarians are seeking educational resources on heartworm disease.

Aedes albopictus (Diptera: Culicidae): an experimental and natural host of Dirofilaria immitis (Filarioidea: Onchocercidae) in Florida, USA. 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. A significant positive correlation was, MeSH 4332 E MEARENTE S PROVO UT 84606-8099. All Rights Reserved. If you are not sure of the full 9-digit ZIP Code, use the 5-digit ZIP Code to avoid loss of letter or package. To verify that qPCR pools were positive for D. immitis, all positive amplicons were submitted to Eton Bioscience (San Diego, CA, USA) for Sanger sequencing. Google Scholar. MRSB analyzed and interpreted the data and prepared the original manuscript. "At the beginning of spring 2020, many veterinarians saw a drop in wellness visits and heartworm Veterinary Treatment Facility reminds pet owners of heartworm disease risks. Find out what the heartworm prevalence is in your own zip code: Check out our disease prevalence maps here> Mosquitoes, Dogs and Heartworm Disease canadensis and An. b Heartworm prevalence within mosquitoes ranged from 0% to 3.09% by zip code. We did not find a relationship between log mosquito abundance and within-host heartworm prevalence (F(1, 16)=0.396, P=0.538). The dominant Anopheles vectors of human malaria in Africa, Europe and the Middle East: occurrence data, distribution maps and bionomic prcis. 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. 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. 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. Owner Name. 4324 E MEARENTE S PROVO UT 84606-8099. While a previous study has investigated dog heartworm prevalence within mosquitoes in an urban to rural gradient [21], the effects of urbanization-driven mosquito diversity changes on the pathosystem have not been previously considered. Article Our results demonstrate that anthropogenic land-use change alters vector-borne disease risk. Ferraguti M, Martnez-de la Puente J, Roiz D, Ruiz S, Soriguer R, Figuerola J. PubMed Data-driven identification of potential Zika virus vectors. However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. 2011;26:17885. Our results suggest that decreases in mosquito diversity due to urbanization lead to decreases in dog heartworm prevalence. We approached this question by sampling mosquitoes across Wake County, North Carolina, USA, analyzing the mosquitoes for the presence of D. immitis DNA, and comparing heartworm prevalence rates within the mosquito to heartworm prevalence rates within domestic dogs. However, mosquito diversity metrics were positively correlated with host heartworm prevalence. Any dogs without heartworm test results or a designated zip code were removed from analysis. quadrimaculatus) are known to be competent heartworm vectors [20]. 2, Spearmans =0.494, P=0.027). Med Vet Entomol. Sequences were assembled using the Geneious 9.1.8 native de novo assembly algorithm and consensus sequences were generated for each sample. Terms and Conditions, Copyright 2023 Today's Veterinary PracticeWeb DesignbyPHOS Creative. We investigated seasonality of D. immitis transmission within Wake County by plotting the overall percent positive pools across the sampling season. All other mosquito species had less than 1.4% D. immitis-positive pools and MLEs of less than 7.1/1000. He has held various roles with Boehringer Ingelheim since leaving private mixed-animal practice in 1993. Mosquitoes are a diverse family of flies that can be pests and vectors of medical and veterinary significance, transmitting a wide array of viruses, protozoans and parasitic nematodes to both humans and animals. 2017;243:1823. With regard to socioeconomic status, we found support for our prediction of a negative relationship with heartworm prevalence within the host. However, with vector diversity being linked to both increased and decreased disease transmission depending on the pathosystem, D. immitis risk as a function of urbanization-induced vector diversity changes is difficult to predict. Paras KL, obrien VA, Reiskind MH. Large Dog (50.1-100 lbs as an adult) $43.00. Clin Microbiol Rev. McTier, T.L., Kryda, K., Wachowski, M. et al. We trapped at each site biweekly from June through mid-October in 2015, and June through the end of October in 2016. 2013;50:76472. Testing data from thousands of veterinary practices and shelters is used to create a detailed map showing the average number of heartworm-positive cases per clinic. Of the thousands of U.S. veterinary practices that report testing data to the AHS, a large proportion have reported data from their practice records year after year. ) We compared within-mosquito heartworm infection across land-use types by Kruskal-Wallis and likelihood ratio tests. Despite these limitations, shelter data presents a large, readily available dataset that generally cuts across various human demographics, including income and education levels [45], and is the best data currently available with which to test our predictions. 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. 2017;6:e22053. Of the total 2488 pools tested, 15 were positive for the presence of D. immitis DNA (Table1). The site is secure. Lee AC, Montgomery SP, Theis JH, Blagburn BL, Eberhard ML. Each of these smaller natural sites had a radius of at least 100m of undeveloped land around the trap, which is an appropriate radius given previous findings on mosquito habitat fidelity [28]. 2008;45:102330. Additionally, each 96-well plate included both a reaction with no template and a reaction with DNA extracted from a known negative laboratory-reared mosquito as negative controls. a Heartworm prevalence within dogs ranged from 3.77% to 15.64% within zip codes where mosquitoes were sampled. albopictus not being a primary heartworm vector. 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.
