RESUMEN
La realización del proceso Diagnóstico Rural Participativo tiene como objetivo: a) mejorar el contacto delos sensores, las Unidades Informativas y Unidades Departamentales con las comunidades de productores y ganaderos; b) fortalecer la red de vigilancia a través de involucrar a la comunidad; c) general información de las percepciones sanitarias a nivel local; d) identificar las enfermedades principales de la zona y priorizarlas; e) investigar los problemas identificados en forma participativa; f) desarrollar estrategias de control conjuntamente con los productores, y g) mejorar el control de las enfermedades animales.

Bovine brucellosis exists endemically at an estimated prevalence of 10% in the developing dairy industry of Santa Cruz in tropical Bolivia. This paper describes field testing of an FAO/IAEA indirect ELISA for brucellosis, as a possible replacement confirmatory test for the complement fixation test (CFT). The ELISA and CFT were compared on sera from 3 cattle populations: a non-vaccinated negative population, an S19-vaccinated negative population, and a brucellosis-positive population of unknown vaccination status. The CFT and ELISA showed excellent specificities of 100% and 98% respectively against the negative non-vaccinated group. The CFT maintained a specificity of 98% against the S19-vaccinated negative group, but ELISA specificity fell to 83% using a cut-off of 20% of positive control, and 94% using a cut-off of 40% of positive control. Against sera from the positive population, the ELISA gave many more positive reactions than the CFT, probably a combination of both higher sensitivity and lower specificity. It is concluded that as Santa Cruz is entering a phase of brucellosis control rather than eradication, the extra sensitivity of the ELISA is not valuable enough to risk a higher level of false positive reactions, especially as S19 vaccination is being increasingly used.

In 1984 capripox entered Bangladesh developing into a severe epidemic causing high mortality in the indigenous goat population. Although at present mainly confined to the western districts the disease has spread to some central and northern districts and unless controlled could spread further. Clinically and biochemically the strain is closely related to a strain previously isolated in central India. It has been shown that restriction endonuclease analysis of the genome of field isolates of capripoxvirus can provide a useful epidemiological technique in investigating outbreaks of capripox.

Capripox was shown to be endemic in all the provinces of the Yemen Arab Republic and the Sultanate of Oman. Investigations into outbreaks of capripox indicated that some strains of capripox virus were infecting both sheep and goats and this was confirmed by inoculating experimental sheep and goats with isolates derived from field cases. The husbandry methods prevalent in the Middle East predispose to the rapid spread of capripox and annual vaccination of all sheep and goats must be considered as the only effective method of controlling the disease.
