The aim of this cross-sectional study was to determine the prevalence of Dirofilaria immitis in stray dogs (n = 523) from the six Parishes of Grenada. Necropsy records were reviewed;information on the distribution and lesions of Dirofilaria immitis was recorded. A total of 144 from 523 dogs (27.5%;95% CI: 23.9% to 31.5%) were positive for Dirofilaria immitis on necropsy. This study shows that heartworm disease is prevalent in stray dogs in all the Parishes of mainland Grenada. This is a progressive, life-threatening disease and thus, there is a need to screen and prevent it within the stray dog population of Grenada.展开更多

This retrospective study conducted from 2005 and 2011 sought to evaluate the total number of TVT cases, and to report extragenital TVT lesions in dogs from the small tropical island of Grenada, West Indies. Evaluation of the biopsy and necropsy specimens from dogs with TVT was carried out by cytological and histopathological methods. In the present study, we observed a total of 78 dogs with TVT, comprising 40 male and 38 female dogs. Most cases were from dogs between 3 and 6 years;less frequently from older dogs (over 6 years) or younger dogs (1 - 2 years of age). In the present study, we report 15 cases (19.2%) of dogs with TVT in extragenital sites. Tumors were noted in the nasal cavity, eye orbit, spleen, liver, skin, ribs, subcutaneous, and submandibular, cervical and inguinal lymph nodes. There was also evidence of metastasis to the ovaries in 2 dogs. The most interesting finding was the presence of extragenital lesions without primary genital involvement in 4 cases (5.1%). Our findings emphasize the need to consider TVT on the list of differential diagnosis for masses in extragenital sites in dogs from geographic regions where TVT is prevalent.展开更多
