Evaluation of anthelmintic activity of liquid waste of Agave sisalana (sisal) in goats

It was evaluated the anthelmintic activity of Agave sisalana (sisal) juice against gastrointestinal nematodes and its potential toxic effects in goats. In vitro tests showed more than 95% reduction in larval counts of the genus Haemonchus spp. at concentrations between 86.5 and 146.3 mg.mL(-1). In vivo the percent reduction of larvae of the fourth (L4) and fifth (L5) stages of Haemonchus, Oesophagostomum and Trichostrongylus was less than 95% in groups GI and GII, and between 80 and 90% in group GIII. A. sisalana juice at the concentrations tested in vitro was effective against gastrointestinal nematodes in goats; however, its anthelmintic efficacy was reduced when administered to animals.

Efeitos do suco de alho (Allium sativum Linn.) sobre nematódeos gastrintestinais de caprinos

The objective of this work was to evaluate the effects of the garlic juice on goat gastrointestinal nematodes. Twenty animals were alocated into two groups and treated with garlic juice. One group was treated with ivermectin and one control group was not treated. The percentage reductions in egg and larvae counts of the Strongyloidea were under 95% for all groups. The treatment of goats with garlic juice was not an effective control of gastrointestinal nematodes.

Inquérito soroepidemiológico do lentivírus caprino e perfil das criações de caprinos na região do Baixo Médio São Francisco (BA)

This work aimed to determine the serological prevalence of caprine artrithis encephalitis (CAE) in the microregion of Juazeiro, in the state of Bahia, using the technique of agar gel immunodiffusion (AGID) to characterize the farming systems of the region. We collected 693 blood serum samples of goats from 46 farms in 8 different locations belonging to the municipalities forming the microregion (Campo Alegre de Lourdes, Casa Nova, Curaca, Juazeiro, Pilao Arcado, Remanso, and Sobradinho). During the visits, a questionnaire was applied emphasizing information related to health management. All of the visited properties had extensive breeding systems, with predominance of mixed breed animals, low productivity and low technology rate, aiming mainly to use the meat. The main diseases reported were caseous lymphadenitis, diarrhea, ectoparasites and keratoconjunctivitis. Concerning seroprevalence, 0.29% (2/693) of samples tested positive for AGID. The positive animals belonged to the same property in the municipality of Curaca, which showed 12.5% (1/8) of positive properties, in contrast to 2.17% (1/46) of total seroprevalence in the other visited properties. These results therefore suggest the need for new epidemiological surveys in the region, especially at a time when the importation of animals for genetic improvement is taking place.

Inquérito soro-epidemiológico de Brucella ovis em rebanhos ovinos no semiárido baiano

In order to analyze the occurrence of antibodies to Brucella ovis in sheep in a semi-arid region, this survey was conducted in the micro-region of Juazeiro, Bahia State, Brazil. The agar gel immunodifusion test (AGID) was used to examine 694 serum samples of 58 flocks. Antibodies to B. ovis were found in 5 (0.72%) of the investigated animals. It is believed that this low number of positive cases is related to the characteristics of the production. The predominant system is the extensive one, with presence of locally adapted breeds and crossbred animals, aiming at the production of meat and skin, with low productivity rates and technical development.
