Seroepidemiology of cutaneous leishmaniasis from Ribeira do Iguape Valiey. Igm and Igc anttbodtes detegted by means of an immunoenzymatic assay (Elisa)

By means of an immunoenzymatic assay (ELISA) IgM class anti-L. braziliensis antibodies are reported in a series of sera from clinical.cases of Cutaneous Leish. maniasis and normal individuals, from Ribeira do lguape Valley, São paulo State, Brazil. The antibody specificity was demonstrated by absorbing the sera with heat-aggregated gamma globulin. Anti-L. braziliensis IgM antibodies were present in treated and untreated Cutaneous Leishmaniasis sera and in 43.21% of normal sera from the same geographical sera. IgG antibodies were present in 86.0% of clinical cases of Cutaneous Leishmaniasis

Structural features and lamellar mechanoreceptors of the collared peccary’s tongue (Pecari tajacu, Linnaeus 1758)

Collared peccaries are omnivorous mammalians well known for presenting a prominent skin gland, known as scent gland. We’ve previously described the histological organization of the palate and lip of this peccary and found several small and large lamellar corpuscles (Vater-Pacini corpuscle) mostly grouped in small aggregates distributed along its lamina propria-submucosa. Here, we described the anatomic structure and histological organization of the tongue of the collared peccary by means of light microscopy. The main features were the presence of a prominent rostral anterior salivary gland and the widespread presence of lamellar corpuscles that could contribute to the tactile function of the tongue
