Abstract

Toxoplasma gondii (T. gondii) is a nearly ubiquitous organism that infects humans, wildlife, birds, and domestic, as well as food animals. T. gondii has been reported in pigs, chickens, sheep, goats and cattle (1). However, only members of the cat family (Felidae) are the definitive host and shed the environmentally resistant oocyst form of the organism in their faeces. Transmission to humans usually occurs by ingestion of cysts in undercooked meat and exposure to soil and water contaminated by oocysts (2). Feline infections are typically subclinical; congenitally infected kittens are the most likely to have clinical signs of infection, but previously clinically healthy adult cats may also be affected (3). Despite the disease’s public health significance, there are still very few studies that have been done on T. gondii here in Zambia. This study was a cross-sectional survey carried out to investigate the seroprevalence and risk factors of toxoplasmosis. A survey was carried out using a questionnaire which was distributed to cat owners as they attended the veterinary clinics. The questionnaire had demographic data for the cats, questions related to the risk factors of toxoplasmosis in cats and practices surrounding the cat owners, like how they handle cat litter, whether their cat was indoor or outdoor, contact of the cat with other cats, and straying behavior of their cat. A total of 178 blood samples were collected from both stray and domestic cats in this study. Of the 178 samples tested for T. gondii IgG antibodies, 88 were from domestic cats and 90 from stray cats. Thirty out of 178 samples were positive for antibodies indicating an overall seroprevalence of 16.85%. From the 30 seropositive samples that tested positive, 60% (18) came from domestic cats and 40% (12) from stray cats. The seroprevalence for domestic cats was found to be 20.4% and that of strays 13.3%. The two risk factors found to be associated with toxoplasma Seropositivity include sex (p=0.007, 95%,CI 0.071,0.976) and diet (p=0.038, 95%,CI 1.395,95.418) It has been concluded that Toxoplasma gondii is widely spread in the study population and the presence of the antibodies is an indication that at one point in their lives, these cats were actively infected and shedding oocyst in the environment thereby posing a risk to humans and other species like sheep and chickens.
