ABSTRACT
Toxocariasis is a widespread zoonosis and is considered an important worldwide public health problem. The aim of this study was to investigate the frequency of trans-mammary Toxocara canis infection in newborn BALB/c mice nursed by females experimentally infected with 1,200 eggs after delivery. After 50 days of age, the presence of larvae in different organs of the offspring was investigated. Trans-mammary infection was confirmed in 73.9% of the mice that had been nursed by infected females. These data show a high trans-mammary transmission of T. canis and confirm the significance of this transmission route in paratenic hosts.
RESUMO
A toxocaríase é zoonose amplamente difundida e considerada importante problema de saúde pública. O objetivo deste estudo foi avaliar a frequência da transmissão transmamária de Toxocara canis em camundongos BALB/c neonatos amamentados por fêmeas experimentalmente infectadas com 1.200 ovos logo após o parto. Após 50 dias de idade, foi avaliada a presença de larvas em diferentes órgãos dos neonatos. A infecção por via transmamária foi confirmada em 73,9% dos camundongos amamentados por fêmeas infectadas. Estes dados demonstram elevada transmissão transmamária de T. canis e confirmam a importância desta via de transmissão em hospedeiros paratênicos.
