Antioxidant enzymes in erythrocytes from goats seropositive to the sheep nose bot fly (Oestrus ovis L., Diptera: Oestridae) infection.
Oestrus ovis (Diptera: Oestridae) causes an important cosmopolitan parasitosis of the nasal and sinusal cavities of sheep and goats called oestrosis. Our objective was to analyze the participation of erythrocytes in the antioxidant system in goats seropositive to O. ovis infection under field conditions. Fifty female goats naturally exposed to O. ovis infection from Baja California Sur, México,...
متن کاملPrevalence of Oestrus ovis (Diptera: Oestridae) in sheep from the São Paulo Central region, Brazil.
The heads of 139 slaughtered sheep were examined with the aim of determining Oestrus ovis prevalence and infestation intensity in the central region of the State of São Paulo, Brazil. Heads from slaughtered sheep were examined and the first (L1), second (L2) and third (L3) O. ovis larval instars were recovered from the nasal and sinus cavities. O. ovis larvae were detected in 13.7% of the sheep...
متن کاملIgG antibody response against salivary gland antigens from Oestrus ovis L. larvae (Diptera: Oestridae) in experimentally and naturally infected goats.
The aims of this study were to analyze the systemic IgG responses against third-instar salivary gland (L3SG) antigens by ELISA in Oestrus ovis experimentally infected kids (EIK) and in naturally exposed adult goats (NEG). Firstly, kids (n=4 per group) were assigned to receive intranasally 0, 12, 24, 36, and 48 first-instars in experimental infections. Blood samples were taken from EIK at Days 0...
متن کاملEpidemiology of Oestrus ovis (Diptera: Oestridae) in sheep in Botucatu, State of São Paulo.
The seasonal factors that influence Oestrus ovis infestation in sheep were determined in Botucatu, State of São Paulo, Southwestern Brazil, from April 2008 to March 2011. Two tracer lambs were monthly exposed to natural infestation by O. ovis larvae for 28 consecutive days, by grazing with a sheep flock. Tracer animals were then euthanized and the larvae of O. ovis recovered from nasal and sinu...
متن کاملCellular and humoral local immune responses in sheep experimentally infected with Oestrus ovis (Diptera: Oestridae).
Cellular and humoral local responses were investigated following repetitive artificial Oestrus ovis infections in lambs. The presence of larvae induced a huge local recruitment of either leucocytes (T and B lymphocytes, macrophages) or granulocytes (eosinophils, mast cells and globule leucocytes). This cellular response was more pronounced in the ethmoid and sinus (development sites of second a...
