Background: 3). Correspondence to Acta Trop. 2012;181:111. The authors declare that they have no competing interests. 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. 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. 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). Conclusions: We compared within-mosquito heartworm infection across land-use types by Kruskal-Wallis and likelihood ratio tests. This approach sought to assess whether the heartworm status of mosquitoes was a reliable predictor of infection status within the host. Google Scholar. Article No state in the U.S. is heartworm-free, according to the AHS survey. Dogs weighing 2-8 lbs should be given one Interceptor Plus chewable tablet (Brown Box . J Wildl Dis. Among veterinarians who believe heartworm incidence increased, leading reasons cited were an increase in heartworm-positive pets coming from heartworm-endemic areas, poor compliance among pet owners, and weather trends that caused an increase in mosquitoes. We calculated heartworm prevalence within dogs by zip code in Wake County. Make an appointment. 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. 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. 2016;94:31421. 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. 2023 BioMed Central Ltd unless otherwise stated. A risk map for D. immitis infection within the canine host shows a trend of higher prevalence in eastern and southern Wake County zip codes (Fig. We calculated mosquito rarefied richness, Pielous evenness and ShannonWiener diversity as previously described [10] and found the average for a given zip code, then performed linear regressions comparing these diversity measures to within-host heartworm prevalence, testing the hypothesis that mosquito diversity impacts heartworm disease transmission. Parasit Vectors. The 2019 AHS Heartworm Incidence Survey shows that heartworms maintain a stubborn hold in the United States. albopictus. We found significant differences in within-mosquito D. immitis prevalence among land-use types (KruskalWallis test: 2=8.555, df=2, P=0.014). Dowling Z, Ladeau SL, Armbruster P, Biehler D, Leisnham PT. On the other hand, it is clear that there is a straightforward answer to this: persuade more pet owners to use preventives and convince them to protect dogs and cats year-roundwith no lapses. 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. We found that suburban areas generally had the lowest within-mosquito heartworm prevalence, and that mosquito diversity was positively correlated with heartworm prevalence within the canine host. Accessed 30 Jun 2018. Sci Rep. 2016;6:29002. Before However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. J Med Entomol. Because of their inability to be infectious for D. immitis, we excluded males and nulliparous females from further analysis.

Parasit Vectors. https://www.heartwormsociety.org/veterinary-resources/incidence-maps. 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]. In a separate facility, we extracted DNA from each pool using either the DNeasy Blood and Tissue Kit (Qiagen, Venlo, Netherlands) or the ZR Genomic DNA-Tissue MiniPrep (Zymo Research, Irvine, CA, USA). Address example. While the directionality of its relationship with mosquito communities remains unclear, it is evident that socioeconomic status has the ability to alter susceptibility of hosts, vector exposure, and therefore disease risk. Animals. 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. C'EST POUR AUJOURD'HUI ET POUR DEMAIN. The datasets analyzed during the present study are available in the Figshare repository: https://doi.org/10.6084/m9.figshare.9339302.v1. No apparent seasonal trends in D. immitis-positive status were noted within the mosquito trapping season (see Additional file 2: Figure S1).

Species-level heartworm prevalence by land-use type. Contrary to our initial hypothesis, when comparing the land-use types of suburban neighborhoods, undeveloped woodlots and undeveloped fields, we found that field areas had significantly higher prevalence and likelihood of heartworm-positive mosquitoes than did suburban areas. To help veterinary professionals, shelter personnel, and pet owners understand heartworm trends in their areas, the American Heartworm Society (AHS) began tracking U.S. heartworm incidence in January 2002. Med Vet Entomol. Generally, yes, but the parameters are usually a bit broader. J Med Entomol. albopictus as the areas primary vector [21]. With regard to dog heartworm disease, this loss of mosquito diversity is associated with decreased heartworm prevalence within both the vector and the host. University College of Veterinary Medicine. Little E, Biehler D, Leisnham PT, Jordan R, Wilson S, LaDeau SL. Spence Beaulieu, M.R., Federico, J.L. It is caused by a parasitic worm. As dog heartworm disease is vectored by an assemblage of mosquito species, changes in mosquito diversity will likely affect disease prevalence. 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. 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. eCollection 2022. We investigated seasonality of D. immitis transmission within Wake County by plotting the overall percent positive pools across the sampling season.

Since parity data for mosquitoes were collected only in 2015, we assessed for correlation of parous mosquitoes with heartworm-positive pools in 2015. After excluding males and nulliparous females as previously described, 8483 individuals in 2488 pools were tested for the presence of D. immitis DNA. Examining landscape factors influencing relative distribution of mosquito genera and frequency of virus infection. Top Companion Anim Med. Aedes albopictus (Diptera: Culicidae): an experimental and natural host of Dirofilaria immitis (Filarioidea: Onchocercidae) in Florida, USA. 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. 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. 8600 Rockville Pike Any opinions, findings and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation. albopictus not being a primary heartworm vector.

Additionally, lower socioeconomic status could increase disease risk via increased vector exposure, either through behavioral factors (e.g. Sequences were assembled using the Geneious 9.1.8 native de novo assembly algorithm and consensus sequences were generated for each sample. Menu. For each neighborhood, we trapped at a single house with homeowner approval, verifying that homeowners did not intend on doing any mosquito barrier sprays or insecticidal treatments during the study period. We cannot assess spatial trends for D. immitis within mosquitoes due to low overall prevalence (Fig. The AHS released the results of the most recent survey, which reflects testing results from the 2019 calendar year. 2016;143:8749.

We acquired median household income by zip code from the 20132017 American Community Survey using U.S. Census Bureaus American FactFinder tool [37] to investigate whether D. immitis prevalence within dogs and socioeconomic status is correlated. and canine heartworm (Dirofilaria immitis) in the mosquitoes of Tennessee. Parasit Vectors. Distinguishing nulliparous from parous female Culex tarsalis by examination of the ovarian tracheation. Zoetis. Our results suggest that decreases in mosquito diversity due to urbanization lead to decreases in dog heartworm prevalence. 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. Article See this image and copyright information in PMC. Becker B, Leisnham P, LaDeau SL. 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. 2006;135:30314.

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. 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. However, since mosquitoes are responsible for transferring the parasite . 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). Each dot represents the center of a zip code containing at least one feline heartworm antigen positive. Based on the results of a prior study of heartworm prevalence on an urban to rural gradient [21], we hypothesize that older neighborhoods with less diverse mosquito assemblages dominated by Ae. Changes in weather patterns. [1,2,3,4]). Steiger DBM, Ritchie SA, Laurance SG. Ae. 2017;42:1849. While no host-level factors were explicitly investigated as drivers of dog heartworm prevalence in the present study, these factors are potentially important to dog heartworm disease dynamics and should be addressed in future studies.

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. 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. 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. All samples and controls were run in duplicates to ensure accuracy of results. Enter the email address you signed up with and we'll email you a reset link. MRSB analyzed and interpreted the data and prepared the original manuscript. Field sites had greater likelihood of a mosquito being positive for D. immitis than did suburban sites (LRT statistic =5.81, Holm adjusted P=0.048), but the probability at wooded sites did not differ from that at suburban sites (LRT statistic =0.013, Holm adjusted P=0.911) or field sites (LRT statistic =4.99, Holm adjusted P=0.051). Heartworms live approximately 5 to 7 years in the dog. 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. Model selection revealed within-host prevalence was best predicted by a positive relationship with mosquito Shannon-Wiener diversity and a negative relationship with household income. The Heartworm Hotline column is presented in partnership between Todays Veterinary Practice and the American Heartworm Society (heartwormsociety.org). This agrees with findings from a recent study that demonstrated a negative correlation between human population size and within-host heartworm prevalence [40]. With regard to dog heartworm disease, this loss of mosquito diversity is associated with decreased heartworm prevalence within both the vector and the host.

In addition to unmeasured host factors, this study is limited by the spatial scale of the within-dog heartworm prevalence data that we acquired. 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. Reiskind MH, Griffin RH, Janairo MS, Hopperstad KA.

Role of vector control in the global program to eliminate lymphatic filariasis. 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). 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. 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.
