All rights reserved Short Communication Human toxoplasmosis and the role of veterinary clinicians Laura Kramer Department of Animal Health- Veterinary Parasitology Laboratory- University of Parma Parma Italy Published Human toxoplasmosis is one of the most common parasitic zoonoses worldwide. As for other zoonoses veterinarians play an important role in the education of the human population regarding the risk of infection. Knowledge of the parasite s biological charateristics life cycle and trasmission routes is necessary to correctly illustrate real risk factors to those people who have direct contact with animals farm animals pets etc . Toxoplasmosis represents one of the more difficult educational challenges for small animal clinicians. Veterinarians are often faced with the need to explain to their clients that it is not necessary for example to give away one s cat during pregnancy and that if they follow a few very simple rules living with their pets need not represent any risk for infection with Toxoplasma gondii. Cats are the definitive host of T. gondii they are the only animals that pass oocysts in their feces. They become infected by eating infected rodents birds or other small animals. Once oocysts are shed they require 1 to 5 days to sporulate and become infective. Cats pass oocysts for only 2 to 3 weeks following primary infection. Mature cats are less likely to shed Toxoplasma if they have been previously infected. Litter box hygiene is the main precaution in preventing transmission of toxoplasmosis from pet cats 1 . A Toxoplasma-infected cat that is shedding the parasite in its feces approximately 2 of the cat population at any given time contaminates the litter box. If the cat is allowed outside it can contaminate the soil or water in the environment as well. Litter boxes should be cleaned daily and not placed in .
