[Simultaneous toxoplasmosis and larval toxocariasis infection in the Czechoslovak population]

The authors discuss the coexistence of infection with toxoplasmosis and larval toxocariasis in man. Both these zoonoses are the most widespread and most serious of all tissue parasitoses on the territory of the CSSR. Knowledge of the incidence and frequency of concurrent infections is important for the differential diagnosis and therapy. In the introduction the authors mention briefly the incidence of toxoplasmosis and toxocariasis in animal hosts on the territory of the CSSR, deals with the developmental stages of the two parasites, Toxoplasma gondii and Toxocara canis and Toxocara cati which are infectious also for man, and with the transmission of infection. In the world literature there are so far only two papers dealing with the parallel course of these two zoonoses and they present only one confirmed case of concurrent disease in man. In the diagnostic group investigated by the authors during examination of tissue helminthoses among almost 9000 examinations larval toxocarosis was diagnosed 798 times. These patients were examined repeatedly to investigate the dynamics of toxocaral antibodies and concurrently possible toxoplasmatic antibodies. In 45 instances concurrent toxoplasmosis was revealed. In the discussion the author deals with possibilities and interrelations of infection with the two parasitoses.
