Abstract

Some species of Paramphistomidae (Trematoda: Digenea) that parasitize the digestive system of ruminants can cause decreases in milk and meat production. In Colombia, paramphistomosis cattle have been recorded from (1) dairy farms at high altitudes in the mountains of Antioquia (northwestern...

Abstract

In Colombian cattle, T. vivax occurs as an enzootic up to 900 m above sea-level; at higher altitudes its sporadic occurrence is attributed to cattle movement from enzootic areas and to the presence of bloodsucking insects. The outbreak described occurred at a latitude between 5-6° north and...

Abstract

The author spent a year investigating protozoal infections among about 4000 cattle in Colombia. Some deaths were caused by infections with Anaplasma marginale, Babesia bovis and Trypanosoma vivax. Other parasites identified in blood smears were Eperythrozoon wenyoni, Babesia bigemina, Trypanosoma...

Abstract

B. bovis antigen derived from infected Boophilus microplus from Cordoba (Colombia) and cultured for 4 years in the laboratory was evaluated in the ELISA and was compared with Australian B. bovis antigen from cattle. The ELISA technique, in which the results were assessed by the difference in...

Abstract

The seroepidemiology of B. bovis infections in cattle in Cordoba, and its adjacent areas in northeastern Colombia, was studied using IFAT. A survey including 1191 serum samples from 79 farms revealed an overall infection rate of 73.4%. The inoculation rates (I) of calves aged 4 to 10 months were...

Abstract

Calves on 3 farms in Cordoba province were bled weekly or fortnightly from May 1987 to April 1988 to detect T. vivax infections. T. vivax was transmitted on all 3 farms throughout most of the year, reflecting an endemic situation with the monthly incidence of infection ranging from 0-61.5%. There...

Abstract

A comprehensive computer model was developed for simulation of the population dynamics of B. microplus and B. annulatus. The model is deterministic and based on a dynamic life table with weekly time steps. The model simulates the effects of major environmental variables, such as ambient...

Abstract

Faeces from 1711 cattle from 113 farms in 8 dairy areas of Colombia were examined for parasite eggs and cysts. Fasciola hepatica eggs were not detected in farms below an altitude of 2000m, but were found in 193 of 869 faecal samples from 34 of 57 farms above this level. Strongyle eggs were found in ...

Abstract

Anaplasma marginale, Babesia bigemina and B. bovis were present in 8 herds of crossbred cattle or crossbred zebu on the North coast of Colombia, but only B. bovis infection was associated with reduced weight gain.

Abstract

Four calves were experimentally infected with Babesia bovis or B. divergens or Anaplasma marginale + B. bovis or B. bovis + B. divergens + A. marginale. Indirect fluorescent antibody tests (IFAT) were made with their sera and blood films. The antigen preparations of A. marginale were all...
