Follicular thyroid carcinoma in an inbred family of mongrel dogs in Trinidad & Tobago.

Thyroid tumors occur in many domestic species, but are most common in the dog, in which they are classified as follicular or medullary. During 2012-2016, we received tissue specimens or whole carcasses of 4 dogs with variable enlargement of the thyroid glands. The 2 males and 2 females were of mixed (mongrel) inbreeding, 3-4.

Completing the Puzzle: A Cluster of Hunting Dogs with Tick-Borne Illness from a Fishing Community in Tobago, West Indies.

Eight hunting dogs were visited by a state veterinarian on the island of Tobago, Trinidad and Tobago, West Indies, as owners reported anorexia and paralysis in five of their dogs. The veterinarian observed a combination of clinical signs consistent with tick-borne illness, including fever, anorexia, anaemia, lethargy and paralysis. Blood and ticks were collected from each dog and submitted to a diagnostic laboratory for analysis.

Hematological profile of healthy Thoroughbred foals from birth to one month of age in Trinidad, West Indies.

Objective: This study aimed to develop a sound database for the hematological reference intervals of thoroughbred foals in Trinidad, West Indies from birth to 1 month of age.

Animals: 89 foals.

Methods: Whole blood samples were taken from 89 foals throughout Trinidad at approximately 1 day, 1 week, and 1 month of age.

First reported case of leishmaniasis in a cat in Trinidad and Tobago.

A 3-year-old, female, domestic shorthair cat, was presented to the Veterinary Teaching Hospital at the School of Veterinary Medicine (SVM), Trinidad and Tobago for a swollen nose, and multiple, variably sized small masses on both ears. The initial diagnostic tests included a CBC, serum biochemistry profile, cytological evaluation of masses on the ear and nose, and FeLV/FIV testing. The CBC and biochemistry results were unremarkable except for a hyperproteinaemia and hyperglobulinemia.

Disseminated Mycobacterium avium subsp. hominissuis infection and ascites in an FIV-positive cat.

A domestic shorthair cat was presented to the Veterinary Teaching Hospital at The University of the West Indies with a history of anorexia, ataxia, and lethargy. On physical examination, moderate abdominal distension and a palpable abdominal fluid wave were noted. Dark yellow, cloudy fluid was collected via abdominocentesis.

A Multicentric T-Cell Lymphoma with a Plasmacytoid Morphology in a Dog.

An 8-year-old male (neutered) Labrador with a history of erythematous skin lesions and exercise intolerance for a prolonged period was suddenly found dead. Necropsy findings revealed an infiltrative, focally extensive mass which occupied 25% of the cardiac interventricular septum. Severe endocardiosis was also found on the bicuspid and tricuspid valves.

A Case Report of Disseminated Canine Histiocytic Sarcoma in Trinidad and Tobago.

Ocular histiocytic sarcomas (as a presenting part of disseminated histiocytic sarcoma) are not commonly diagnosed. A 10-year-old female intact Rottweiler presented to the School of Veterinary Medicine, Trinidad with buphthalmia and pain in the left eye. The cornea of the left eye appeared diffusely opaque with a conjunctival mucopurulent ocular discharge.

Oral Plasmacytoma in a Dog.

A 6-year-old male Pit bull mix dog presented for bleeding from the mouth persisting for five days. A clinical evaluation revealed a 2 × 3 cm soft tissue mandibular mass at the crown of the first premolar, as well as a non-regenerative anemia and hyperproteinemia. Cytologic and histopathologic evaluations of the mass were compatible with an oral plasmacytoma.

Prospective study investigating transplacental transmission of equine piroplasmosis in thoroughbred foals in Trinidad.

Equine piroplasmosis caused by Theileria equi and Babesia caballi is endemic in Trinidad and Tobago. Transmission occurs by ticks of the family Ixodidae. T.

Haematological parameters in stray dogs seropositive and seronegative to Ehrlichia canis in North Trinidad.

In view of the fact that stray dogs are a reservoir for many diseases, this study was undertaken to determine the prevalence of Ehrlichia canis in stray dogs in North Trinidad and to evaluate the diagnostic implications of haematological alterations associated with seropositivity. Overall, 41 (44.6%) of 92 stray dogs were seropositive to E.

A case of transplacental transmission of Theileria equi in a foal in Trinidad.

Equine piroplasmosis due to Theileria equi and Babesia caballi is endemic in Trinidad. A case of equine piroplasmosis due to T. equi was diagnosed in a thoroughbred foal at 10h post-partum.

The influence of age and Rhodococcus equi infection on CD1 expression by equine antigen presenting cells.

Unlabelled: There is a distinct age-associated susceptibility of horses to Rhodococcus equi infection. Initial infection is thought to occur in the neonatal and perinatal period, and only foals less than 6 months of age are typically affected. R.

Granulocytopenia associated with thymoma in a domestic shorthaired cat.

A 5-year-old, spayed female cat was referred because of a mass in the cranial mediastinum noted on thoracic radiographs. A thymoma was diagnosed following ultrasound and biopsy of the mass. Treatment was initiated with coarse-fraction radiation therapy using external-beam therapy (four fractions of 5 Gy).
