Serological survey of Neospora caninum in small ruminants from Pernambuco State, Brazil.

Neospora caninum infection is an important cause of bovine abortion as well as neonatal mortality in goats and sheep. A serological survey for antibodies against N. caninum in goats and sheep was carried out in the municipality of Ibimirim, PE, Northeastern Brazil. The imunnofluoresce antibody test showed that 26.6% (85/319) of the goats and 64.2% (52/81) of the sheep were positive. Serologic reactivity was associated with age in goats (p < 0.01) and sheep (p > 0.05), with increasing rates in older animals. These results indicate exposure to N. caninum among small ruminants in the study area.

A infecção por Neospora caninum é uma importante causa de abortos em bovinos, assim como mortalidade neonatal em caprinos e ovinos. Uma pesquisa sorológica de anticorpos anti-N. caninum foi realizada no município de Ibimirim (PE, Brasil). Os resultados ao teste de imunofluorescência revelaram que 26,6 por cento (85/319) dos caprinos e 64,2 por cento (52/81) dos ovinos foram positivos. A reatividade à sorologia foi associada com a idade nos caprinos (p < 0,01) e ovinos (p > 0,05), com maior ocorrência nos animais mais velhos. Estes resultados indicam exposição a N. caninum entre pequenos ruminantes na área estudada.

The effects of topical application of sunflower-seed oil on open wound healing in lambs

PURPOSE: To demonstrate the effects of the use of sunflower seed oil on the treatment of skin wounds. METHODS: Eighteen male Saint Inês lambs were divided in 3 groups according to the pos-operative (7, 14 and 21 days). After antisepsis and local anestesia, two 4cm2 wounds on each side of the thoracic region, close to the scapule were surgically produced. The experimental wounds were treated with sunflower seed oil, with high concentration of linoleic acid (LA), and the control ones with sterilized Vaseline. Biopsies of the pos-operative wounds tissue were performed on the 7th, 14th, 21st days and histologically evaluated. RESULTS: Topic application of sunflower seed oil accelerated healing process at the 7th and 21st days, reducing wound area and increasing wound contraction. Granulation tissue increased faster on treated wounds. The epidermis of the treated wounds was completely recovered when compared to control wounds. CONCLUSION: The topic use of sunflower seed oil accelerated the healing process, and it can be used as an alternative therapy on second intention wound healing.
