Salmonella gastroenteritis and septicemia were diagnosed in two cats presented for necropsy. Both cats resided in the same household and were fed a home-prepared, raw meat-based diet. Salmonella was isolated from multiple organs in both cats and from samples of raw beef incorporated into the diet fed to one of the cats. Subtyping of the bacterial isolates yielded Salmonella newport from one cat and from the diet it had been fed. This report provides evidence that the practice of feeding raw meat-based diets to domestic cats may result in clinical salmonellosis.
A two-year-old female poodle with abdominal distention was diagnosed with concurrent enteric duplication cyst and lymphangiomatosis. Both lesions were shown as cystic structures, but some characteristic features of enteric duplication cyst were identified including a thick cyst wall and shared blood supply with the duodenum. Although it was challenging to discriminate between the types of cyst based on diagnostic imaging, this report describes the characteristics of each type of lesion using several different imaging modalities.
Abstract. Eastern equine encephalitis virus (EEEV) is anAlphavirus that is endemic in the Southeastern United States. From 1993 to January 2005, the Veterinary Diagnostic and Investigational Laboratory in Tifton, Georgia, performed postmortem examinations on over 101 domestic canines exhibiting clinical neurological disturbances. In 12 of these dogs, brains were histologically suggestive of infection with EEEV. All dogs were less than 6 months of age, with no breed predilection. Clinical signs included pyrexia, depression, nystagmus, and lateral recumbency. Microscopically, brains from all 12 puppies contained infiltrates of lymphocytes, plasma cells, and histiocytes, with occasional neutrophils and random foci of astrocytosis and gliosis. There were mild to moderate perivascular infiltrates of neutrophils along with scattered lymphocytes, plasma cells, and macrophages in the meninges. Viruses isolated from brain homogenates of all 12 puppies were confirmed by indirect fluorescent antibody testing to be EEEV. Additionally, RNA extracted from the brains and viral cultures of 2 dogs were determined by a specific reverse-transcriptase polymerase chain reaction (RT-PCR) to contain EEEV. The single available serum sample exhibited a 1 : 8 serum neutralization titer to EEEV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
