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.

Tick-borne pathogens in neotropical animals in Trinidad, West Indies.

Background: Ticks are important vectors of many pathogens that have contributed to the morbidity and mortality of humans and domestic animals worldwide. Wildlife species have also been implicated as reservoir hosts of a variety of tick-borne pathogens. The objective of this study was to determine which tick-transmitted pathogens were present in the animals harvested from the forest in Trinidad for human consumption.

A Comparison of Peripheral Blood Smears, Autologous Cell Cultures, and Reverse Line Blot Hybridisation in Screening for / in Roaming Dogs and Symptomatic Dogs in Trinidad.

This study compared two methods to detect cases of canine ehrlichiosis in a field setting. One method was a polymerase chain reaction for the 16S rRNA gene followed by reverse line blot hybridisation with genera and species-specific probes for . The second method was an autologous cell culture of peripheral leucocytes isolated from heparinised blood and maintained in a homologous canine serum in Dulbecco's Modified Eagle medium without antibiotics.

A case of Pearsonema eggs in the urine sediment of a cat in Trinidad.

Nematodes of the urinary tract of domestic dogs and cats are a rare occurrence. The discovery of the eggs on urine sediment examination is usually an incidental finding. A twenty-one month old intact queen presented to the Veterinary Teaching Hospital with a history of a serosanguinous vaginal discharge and reddish colour urine for the last ten days.

A comparison of the efficacy of two commercial acaricides (fipronil and amitraz) with Azadirachta indica (neem) on the brown dog tick (Rhipicephalus sanguineus) from canines in Trinidad.

The brown dog tick (Rhipicephalus sanguineus) is prevalent on canids in Trinidad. It is directly (by causing anaemia) and indirectly (by acting as a vector of tick-borne pathogens) responsible for morbidity and mortalities in the canine population. The most commonly used commercial acaricides available to pet owners in Trinidad are amitraz and fipronil.

Survey of ticks of domestic dogs and cattle in three Caribbean islands.

Ticks and the pathogens they transmit can cause high morbidity and mortality in domestic animals. As part of a larger study to determine the tick-borne pathogens infesting domestic animals and wildlife, the aim of this study was to survey the tick species infesting the canine and cattle populations in Trinidad, Tobago and St. Lucia.

Phylogenetic analysis of Theileria equi and Babesia caballi sequences from thoroughbred mares and foals in Trinidad.

The agents of equine piroplasmosis, Theileria equi and Babesia caballi, are endemic in Trinidad, West Indies. While transmission is mainly by ixodid ticks, transplacental transmission of T. equi has also been reported.

Novel incidental finding of Hepatozoon canis infection in two dogs of the same household in Trinidad, West Indies.

A five-year old mixed breed bitch was presented to the veterinary clinic in lateral recumbency with a history of anorexia and muscle hyperaesthesia. Examination of the blood smear of this animal revealed the presence of Hepatozoon spp. gamonts in the neutrophils and monocytes with a parasitaemia level of approximately 2%.

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.
