    Clinically healthy rats with antibodies to Bacillus piliformis were given prednisolone in the last week of pregnancy. B. piliformis was demonstrated in the livers of their offspring. None of the dams or the young rats showed clinical signs of disease. Antibodies to B. piliformis were found in the young rats at birth, and presisted for several months. The importance of potential transplacental infections when attempting to establish colonies free from B. piliformis in discussed.

    Toxoplasmosis

    Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
