ABSTRACT
Lagochilascaris minor is the etiological agent of lagochilascariosis, a disease that affects the neck region and causes exudative abscesses, with eggs, adult parasites and L3/L4 larvae in the purulent exudates. Mice are now considered to be intermediate hosts for the parasite. To determine the pattern of infection in B1 cell-deficient mice, experimental lagochilascariosis was studied in BALB/c and X-chromosome-linked immunodeficient (xid) mice. BALB.xid-infected mice showed lower numbers of larvae. Third-stage larvae, fourth-stage larvae and adult parasites were found in both strains. BALB/c mice produced IgM, IgG, IgA and IgE against the crude extract and secreted/excreted antigens of the parasite. On the other hand, BALB.xid mice did not produce IgM and produced lower levels of IgG and IgA, and similar quantities of IgE.
RESUMO
Lagochilascaris minor é o agente etiológico da lagochilascariose, uma doença que afeta a região de pescoço provocando abscessos exudativos contendo ovos, parasitas adultos e larvas L3/L4 nos exudates purulentos. Atualmente, camundongos são considerados hospedeiros intermediários do parasita. Para determinar o padrão de infecção em camundongos deficientes de células B1, a lagochilascariose experimental foi estudada em camundongos BALB/c e em camundongos com imunodeficiência ligada ao cromossomo X (xid). Camundongos BALB.xid infectados mostraram menor número de larvas. Larvas L3, L4 e parasitas adultos foram encontrados em ambas as linhagens. Camundongos BALB/c produziram IgM, IgG, IgA e IgE contra o extrato bruto e antígenos secretados/excretados do parasita; por outro lado, camundongos BALB.xid não produziram IgM, produziram baixos níveis de IgG e IgA, e quantidades semelhantes de IgE.
