Antibodies to Toxoplasma gondii were determined in serum samples of 502 domestic cats from Brazil by the modified agglutination test (MAT), using formalin-fixed whole tachyzoites and mercaptoethanol. Antibodies (MAT > or = 1:20) were found in 132 (26.3%) of 502 cats. With respect to origin, antibodies were found in 26.7% of 430 stray cats from São Paulo, 10% of 40 stray cats from Guarulhos, and...

INTRODUCTION The present study was conducted to evaluate the prevalence of Trichuris spp. and other intestinal parasitic infections in owned cats on St. Kitts. METHODOLOGY The feces of 41 non-feral cats (23 indoor only; 18 indoor/outdoor) were examined for the presence of Trichuris spp. eggs. RESULTS Nine (22%) of the cats were positive for Trichuris spp. Prevalence of trichuriasis in indoo...

AffectedAnimals: Dogs and cats. Overall, cats are infected by heartworms much less commonly, even in areas in which heavily infected dogs are present. Male cats tend to be infected more commonly and have a larger worm burden than female cats, mostly because male cats spend more time roaming outside and have less resistance to infection than female cats. Cats that spend significant amounts of ti...

The principal aims of this study were to evaluate the humoral immune response (IgG) of cats with gastric Helicobacter spp. infection, and to determine the prevalence of different types of Helicobacter spp. in the stomachs of cats. The Helicobacter infection status of 45 cats (12 healthy spay/neuter cats, 9 sick cats, 24 colony cats) was determined by evaluating endoscopic gastric biopsies for u...

OBJECTIVE To determine the effects of topical 0.5% tropicamide on anterior segment morphology (ASM) and intraocular pressure (IOP) in normal and glaucomatous cats. ANIMALS USED: Normal cats and cats with inherited primary congenital glaucoma (PCG). PROCEDURES Control IOP curves were performed in untreated normal and PCG cats. In the first experiment, tropicamide was applied OD in eight normal...

The development of nonsurgical contraceptives for cats may facilitate population control of the species. The purpose of this study was to investigate the utility of GnRH for immunocontraception of male cats. Male cats (n=12) were divided into groups of three and were immunized once with 0 (sham), 50, 200, or 400 microg synthetic GnRH coupled to keyhole limpet hemocyanin and combined with a myco...

The lymphatic system is directly involved in the gastric diseases development animals. Pathologies of gastrointestinal tract are one first places for female cats. purpose research: to study features topography and morphometry lymph glands cats 3-6 years age. Objects research were stomachs from British breed cats: 10 - aged 3-5 years, years. gland (right and/or left) was recorded 80% animals stu...

We used 5 binocularly deprived cats (BD cats), 4 control cats reared also in the laboratory (C cats) and 4 cats reared in a normal environment (N cats). The cats were trained to discriminate an upward or downward-moving light spot versus a stationary spot (detection task) and then an upward versus a downward spot (direction task). The N and C cats learned slowly. The learning was slower than in...

OBJECTIVE To characterize clinical features of tracheal rupture associated with endotracheal intubation in cats and to evaluate the most appropriate treatment for this condition. DESIGN Retrospective study. ANIMALS 20 cats with a history of endotracheal intubation that subsequently developed dyspnea or subcutaneous emphysema. PROCEDURE Medical records of cats with a presumptive diagnosis ...

Three groups of cats were used: cats deprived binocularly of patterned vision from birth (BD cats), control cats reared in the laboratory with opened eyes (C cats) and cats reared in a rural environment during the first months of life (N cats). The cats were trained to discriminate vertical vs. horizontal oscillations of a light spot for food reward. The task was difficult for all cats. The pre...
