[Experimental infection of goats with Brucella ovis. Bacteriological serological and histopathological studies].

The susceptibility of adult male goats to Brucella ovis infection was studied. Fifteen goats and fifteen rams both of ages ranging from 22 to 34 months were inoculated conjunctivally with 10(9) cells of B. ovis strain recently isolated from a case of ram epididymitis.

Leptospirosis as an animal and public health problem in Latin America and the Caribbean area.

As a major livestock disease, leptospirosis cuts significantly into the world's supply of animal protein through its consequences of abortion and calf mortality, retarded growth, and reduced milk production. Evidently, such losses have severe economic implications as well. The disease's impact has been somewhat diminished in the developed countries thanks to mechanization of rural activities, improved personal and environmental hygiene, and broad application of preventive measures, including the administration of bacterins, in domestic animals.

Comparative value of arecoline hydrobromide and bunamidine hydrochloride for the treatment of Echinococcus granulosus in dogs.

A controlled trial involving 122 dogs experimentally infected with Echinococcus granulosus was carried out to compare the efficiency of arecoline hydrobromide and bunamidine hydrochloride. A single treatment with arecoline hydrobromide at a dose rate of 4 mg/kg or with bunamidine hydrochloride at 50 mg/kg gave a similar degree of efficiency against young worms. At these dose rates, worms were still present in almost half the dogs at autopsy.

Natural Brucella infection in Argentine wild foxes.

In the course of an investigation in 1962-64 into the natural occurrence of brucellosis among grey foxes in Argentina, agglutination tests were performed on 728 sera of the foxes Dusicyon gymnocercus antiquus and D. griseus griseus, captured in the provinces of Buenos Aires and Rio Negro. Agglutination titres of from 1:25 to 1:800 were found in 173 (23.
