ABSTRACT
A case of fibropapillomatosis in a green turtle (Chelonia mydas) is described. This appears to be the first confirmed report from Trinidad. The animal had multiple external tumours but there was no macroscopical or microscopical evidence of internal lesions.

Spirocerca lupi is a common infection in dogs in the tropics, and the clinical disease(spirocercosis) frequently presents with regurgitation of ingested food usually within an hour of ingestion. Clinical diagnosis is often confirmed with thoracic radiographs which reveal eosphageal granulomas, spondylitis and spondylosis of the thoracic vertebrae. In the report we present a case of S. lupi infection characterised by the persistent cough rather than the usual regurgitation. We propose that this is a case of early manifestation when presented with a persistent cough unresponsive to routine treatment.

Congenital duplications are common causes of dystocia in farm animals, especially in cattle. Heteropagus or conjoined asymmetric twins can be differentiated into a dominant and a parasitic twin, which can be classified further by the development of the parasitic twin and its anatomical attachment to the dominant twin (autosite). In epigastric heteropagus, the parasitic twin is attached to the autosite in the epigastric area. Epigastric heteropagus is a very rare condition in all species, but it has previously been reported in human beings (Chadhaand others 1993). There have been no reports of heteropagus in cattle in Trinidad and Tobago, and there is a paucity of information on bovine epigastric heteropagus in the literature. Reports of congenital abnormalities in Trinidad include craniopagus in a calf (Isitor and Adogwa 1992), perosomus elumbus in a goat (Cazabon and others 1994) and cephalothoracopagus in sheep (Cazabon and Adogwa 2003). The interest in congenital abnormalities lies mainly in the aetiology and its implications, such as genetic defects and environmental toxins. This short communication describes the firstcase of epigastric heteropagus in cattle reported in Trinidad and Tobago.

The estimated prevalence and antimicrobial resistances of Salmonella spp. in non-diarrhoeic dogs across Trinidad was determined. The serotypes of Salmonella spp. isolated were also identified. Of a total of 1391 dogs sampled, 50 (3.6%) were positive for Salmonella spp. with 28 different serotypes, the predominant serotypes were Javiana (12), Newport (6), Arechavaleta (5) and Heidelberg (5). Fifty-seven (85.1%) of 67 isolates exhibited resistance to one or more antimicrobial agents. Of eight antimicrobial agents tested, resistance was exhibited to streptomycin (80.6%), cephalothin (37.3%), neomycin (38.8%) and gentamicin (9.0%). All isolates were sensitive to ampicillin, norfloxacin, choramphenicol and sulphamethoxazole/trimethoprim. It was concluded that the isolation of the Salmonella spp. from non-diarrhoeic dogs could pose health hazard to their owners as most serotypes are known to be virulent. Furthermore, the prevalence of resistance to antimicrobial agents amongst the Salmonella isolates from these animals indicates susceptibility testing may influence chemotherapeutic choices when treating these isolates.

Non-steroidal anti-inflammatory drugs (NSAIDs) also have analgesic and anti-pyretic properties. Ketorolac tromethamine (ketorolac) is a potent NSAID which is used mainly for its analgesic properties in humans. Ketorolac is also available as a registered veterinary pharmaceutical product in Trinidad. Off-label use of NSAIDs in dogs has been documented and is occasionally used in small animal practice in Trinidad. Six days after the treatment with ketorolac tablets (5 milligram) once daily for five days, a 20 kilogram (kg) mixed breed female dog was presented to the Veterinary Hospital, School of Veterinary Medicine, Trinidad. A grave prognosis was given based on the clinical signs of anorexia, hematemesis, very pale mucous membranes, melanoma and lateral recumbency. The animal was euthanised and submitted for necroscopy. Severe hemorrhage (140 millilitres) from gastric ulcerations, and multi-focal hepatic necrosis was found on necroscopy. Histopathology reinforced the hypothesis of ketorolac toxicosis causing gastric ulceration. Also noteworthy was a predominantly lymphoplasmacytic infiltrate accompanying a peri-acinar hepatic necrosis. Ketorolac is conjugated by the liver to an inactive metabolite and excreted by the kidney. Data from human and canine studies have consistently recorded gastric ulcerations as a side effect of this drug. Concurrent hepatic disease may have prolonged its duration of activity, thereby increasing the incidence and/or the severity of side effects. Contra-indications for the use of this drug in humans and animals include renal disease, cardiac disease, concurrent gastro-intestinal ulceration, dehydration and shock, but not hepatic disease/insufficiency (AU)
