Cajamarca is an important Andean livestock production area located in northern Peru and at the same time endemic in a poorly studied disease known as paramphistomosis. The purpose of this research was to calculate the frequency of paramphistomids in sheep (Ovis aries) slaughtered in the Camal Municipal de Cajamarca, located in the city of Cajamarca. Between the months of February to September 2019, 386 samples of rumen-reticulum were collected that were later classified by age and origin of the animals. Transferred to the laboratory, the stomach contents were emptied; they were examined meticulously and exhaustively in order to find, collect and recognize the parasites adhering to the walls of the compartments. Nineteen samples were positive for Calicophoron microbothrioides in the rumen and none in the reticulum, thus obtaining a frequency of 4.92% in the presentation of paramphistomids...

Bovine herpesvirus type 1 (BoHV-1) and bovine leukemia virus (BLV) are among the most important pathogens affecting dairy cattle, causing significant economic losses worldwide. The present study determined the seroprevalence of IBR (Infectious Bovine Rhinotracheitis) and BLV in dairy herds in Cajamarca, Peru. A total of 464 animals were sampled, and the presence of antibodies against BoHV1 and BLV was determined using commercial indirect enzyme-linked immunosorbent assay (I-ELISA) kits. Among the sampled animals, the overall seroprevalence was 8.84% (95% CI: 0.5–35.12) for BoHV1 and 7.54% (95% CI: 5.13–9.95) for BLV. The highest BLV seroprevalence was observed in Cajamarca (23.68%), while no positive cases were detected in four provinces. Regarding BoHV1 seroprevalence, it was highest in Cajamarca (26.32%) and Santa Cruz (28.13%), with no cases detected in five of the ten provinces e...
