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]. We created choropleths to visualize risk maps for D. immitis infection within dogs and within mosquitoes in the choroplethrZip package in R [36]. [10]. Reiskind MH, Griffin RH, Janairo MS, Hopperstad KA. After extraction, we quantified the DNA concentration using the Qubit 2.0 Fluorometer (Invitrogen, Life Technologies Corporation, Waltham, MA, USA), accepting any sample with greater than 0.01ng/l of DNA for further analysis.

Comparison of within-mosquito heartworm prevalence by land-use type. 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. salinarius, Ae. The results of the AHS Incidence Survey represent a mix of both bad and good news. To further investigate differences between land-use types while accounting for varying mosquito pool sizes during our molecular analysis, we used a likelihood ratio test to compare probability of within-mosquito D. immitis infection across land-use types. 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). Percent parous mosquitoes and percent Dirofilaria immitis-positive mosquito pools were compared for data from the 2015 trapping season. canadensis and An. The southern megalopolis: using the past to predict the future of urban sprawl in the Southeast US. CAS Future studies could partner with local veterinarians to get finer scale host data, as collection of detailed travel history for newly heartworm-positive dogs would allow for more definitive mapping of spatial and temporal host-level incidence trends. Veterinarians reported numbers of patients tested for heartworm infection, as well as the number of positive cases from that total. May 16, 2019, 6:04 AM. We investigated seasonality of D. immitis transmission within Wake County by plotting the overall percent positive pools across the sampling season. Dr. Duke has special interest in orthopedic and reconstructive trauma surgery. We performed a linear regression of within-mosquito heartworm prevalence versus within-host heartworm prevalence. Comparison of the vector potential of different mosquito species for the transmission of heartworm, Dirofilaria immitis, in rural and urban areas in and surrounding Stillwater, Oklahoma, USA. 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. Positive pools were confirmed via sequencing, with all pools aligning to a portion of the D. immitis mitochondrion [33]. vexans, Cx.

From the survey, the following findings were identified: The 2019 AHS Heartworm Incidence map, as well as maps from 2001 to 2016, can be downloaded at, heartwormsociety.org/veterinary-resources/incidence-maps. Recognizing that mosquito diversity changes as suburban neighborhoods grow older [10], we stratified our mosquito sampling efforts in suburban areas by neighborhood age, creating a chronosequence with which to test our predictions. Mosquito species distribution across urban, suburban, and semi-rural residences in San Antonio. The prevalence in undeveloped wooded sites did not significantly differ from that in either suburban (Z=0.630, P=1.0) or field sites (Z=1.884, P=0.179). Dogs and cats not seen by veterinarians and/or not tested for heartworms during annual veterinary visits may be infected but go unrecognized for years. University College of Veterinary Medicine. 2016;61:395415. 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. [1,2,3,4]). Address example. We used this binary designation as an additional method to investigate any detectable relationships between vector infection and host infection in our dataset. For each mosquito species, we calculated total number of individuals and total number of pools analyzed, the number of pools positive for D. immitis, and the percent D. immitis positive pools. 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. 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. Eight mosquito species had pools that tested positive for Dirofilaria immitis. Lee AC, Montgomery SP, Theis JH, Blagburn BL, Eberhard ML. 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.

While heartworm incidence dropped slightly in some parts of the country in 2019, more veterinarians overall noted an upward trend in heartworm incidence over the previous 3 years than a downward trend. We found that two mosquito diversity metrics were positively correlated with heartworm prevalence within dogs at the zip code level. 2018;6:e4794. 2016;158:197200. de Valdez MRW. Med Vet Entomol. 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). The two variables were positively correlated (Spearmans =0.494, P=0.027). An important factor is that heartworm diagnosis requires one or more blood tests that must be conducted in a veterinary clinic and/or reference laboratory, which limits diagnoses to patients seen in clinics and animal shelters. The 2019 map (. Dowling Z, Ladeau SL, Armbruster P, Biehler D, Leisnham PT. Trends Parasitol. 2, Spearmans =0.494, P=0.027). CAS However, these species only had positive pools detected in undeveloped natural areas. albopictus, the Asian tiger mosquito, which constituted 41.9% of the overall abundance, followed by Culex salinarius and Aedes vexans with 13.9% and 8.3%, respectively. The focus of studies on primary vectors rather than communities of vectors has led to a general gap in knowledge as to how vector diversity contributes to disease transmission in multi-vectored pathosystems, even though the limited empirical and modeling investigations that have occurred suggest vector diversity can increase transmission [5, 6]. This information can be utilized to identify areas of high mosquito diversity that may be foci for heartworm transmission.

Unfortunately, the lack of veterinary care translates to a lack of heartworm prevention, and these pets are among those most likely to be positive, infecting mosquitoes and other dogs in the neighborhood. 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.

It is possible that heartworm disease risk could be higher in urbanized areas [21], where the majority of mosquito bites are likely to be from Ae. 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. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. Spence Beaulieu, M.R., Federico, J.L.

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). J Med Entomol. 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. doi: 10.1146/annurev-ento-010715-023819. 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.
