The aim of this study was to determine the prevalence of Toxoplasma gondii and Mycoplasma agalactiae in sheep and goats from the south of La Guajira and north of Cesar as part of the establishment of a serological profile of these species in the Colombian region. Serum samples (n=1039) were analysed with commercial ELISA kits specific for these pathogens. The global prevalence found in the region was 25.1 and 18.3% for T. gondii and 0.12 and 0.8% for M. agalactiae in sheep and goats, respectively. Positive samples for T. gondii were more frequent in females than in males. Likewise, all samples positive for M. agalactiae were determined in females.

The present study was carried out in the rural area of the department of Arauca, in the Orinoquía region, Colombia. A total of 1351 faecal samples from dual purpose cattle were collected and processed using the Baerman coprological technique for the detection of Dictyocaulus viviparus. A prevalence of 1.7% of D. vivarus is reported in Arauca, whose environmental conditions are considered adverse for the development of the nematode and do not coincide with those traditionally reported in the country and in the world.

The objective of the study was to determine the prevalence of gastrointestinal parasites in bovines from the department of Cesar, Colombia. Faecal samples were collected (n=862) from 27 dual-purpose cattle farms in two municipalities. The animals were stratified into three age groups: 0-12, 12-24 and >24 months. The samples were processed using the coprological techniques of McMaster, Dennis and Baermann. The genera of the parasites were identified according to the morphology of their eggs or infective larvae. The overall prevalence of gastrointestinal parasites was 83.2%, with the highest values for Eimeria sp (77.9%), Strongyloides sp (10.8%) and Haemonchus sp (8.5%). No statistical association was found due to effect of the municipalities, but it was observed due to the effect of the age group on the prevalence of Eimeria sp, Strongyloides, Haemonchus and Trichostrongylus (p<0.0...
