Eucoleus boehmi (syn. Capillaria boehmi) is a trichurid nematode parasite of the upper respiratory tract in canids with a generally asymptomatic course. It is presented the clinical case of a 9-year-old mestizo male canine from the province of Buenos Aires, Argentina, who had previously been treated for eucoleosis, presenting cough, sneezing, reverse sneezing, abundant bilateral serous nasal discharge. The analysis of faecal samples was performed by the Bembrook and McMaster techniques, revealing the presence of 10 900 epg of E. boehmi. Treatment and monitoring of the patient was performed until complete remission of clinical signs and the absence of eggs in the stool.

Coccidiosis is cause of economic losses due to weight loss and growth retardation, decreased feeding efficiency, diarrhea and death of weaning rabbits. The main objective of the work was to evaluate the dynamic change of Eimeria oocyst shedding in the reproductive stage and in weaned litters during the fattening period, in a farm for meat production, with a history of coccidiosis infection. A faecal sample of the following physiological condition was obtained weekly: gestation (G1, G2, G3 and G4) and lactation (L1, L2, L3 and L4), not pregnant or not lactating were also included (V). In weaned rabbits, faecal sample / litters were obtained weekly, until rabbits reached the slaughter weight (2.5 kg). All samples were examined by flotation and the McMaster method. Co-infection with six species of the genus Eimeria could be observed in all positive animals. The infection rate in rabbits var...
