Estimates of intestinal parasite prevalence in canine populations have largely been based on use of fecal flotation methods only. Dogs in animal shelters are likely at higher risk of intestinal parasite infection because of their previous exposure history. Our objectives were to estimate the prevalence of intestinal parasites among Texas shelter do...

Background Various heartworm (HW) diagnostic testing modalities detect products of, or reactions to, different life cycle stages of Dirofilaria immitis. Microfilariae (Mf) can be directly visualized in blood, antigen (Ag) from immature and adult heartworms may be detected on commercial assays, and antibody (Ab) tests detect the host immune response...

Heterobilharzia americana is a trematode parasite (family: Schistosomatidae) of mammalian wildlife that occasionally infects domestic dogs and horses in the southeastern United States. This report presents the first case of H. americana infection in a Grant's zebra (Equus burchelli boehmi). The parasite was diagnosed post mortem as an incidental fi...

The cornerstones of diagnosis of heartworm (HW) in dogs are the detection of circulating antigen from adult female Dirofilaria immitis or the visualization of microfilariae in whole blood. These tests are less sensitive in cats because of the feline immune response leading to low numbers of adult worms, but heartworm antibody tests are also license...

Supplemental Figure. Four‐way Venn diagram demonstrating the occurrence of coinfection or coexposure as well as single infection/exposure for four vector‐borne pathogens among 608 total dogs in seven shelters across Texas.

Supplemental Table 1 Demographic data and results of bivariable and logistic regression analysis of potential risk factors for D. immitis infection status among 608 dogs at 7 animal shelters across Texas Supplemental Table 2 Demographic data and results of bivariable analysis of potential risk factors for Anaplasma spp. seropositivity among 608 do...

Background Vector‐borne diseases have an adverse impact on health of dogs, and infected dogs can be sentinels for human infection. Infection with Trypanosoma cruzi, an agent of Chagas disease, causes fatal heart disease in dogs across the southern United States but has been neglected from wide‐scale prevalence studies. Objectives To determine the...

CASE DESCRIPTION A 1-year-old castrated male dog residing in Indiana was examined because of intermittent vomiting of 4 months' duration. CLINICAL FINDINGS The dog's condition did not resolve with medication. Diagnostic imaging revealed a possible partial obstruction at the ileocecal junction. An exploratory laparotomy was performed. The jejunum co...

Heterobilharzia americana is a trematode parasite (family Schistosomatidae) that infects a wide range of wild mammalian hosts. Canine cases have been reported in the Gulf coast and south Atlantic states, Kansas, and Oklahoma. A total of 238 canine H. americana cases in Texas were retrospectively collected for a period of approximately 22 years from...

A 22-year-old Quarter Horse mare exhibited neurological signs consisting of head pressing, central blindness, minimal ataxia and dysphagia. Despite treatment, the mare collapsed and died shortly after onset of signs. On necropsy, there were approximately 15 l of free blood in the abdominal cavity. A 12 × 4 cm diameter, irregularly-shaped, nodular,...
