Abstract
Some production parameters of seropositive cows (age, first calving age, 305 day mature equivalent last milk yield production, lifetime mature equivalent milk yield production, lifetime total milk production, lifetime total milking period, lifetime monthly milk production, lifetime daily milk production, lifetime total days of milking, number of inseminations per pregnancy (for last pregnancy), number of calves and calving interval (for last pregnancy)) were analysed in the current study. The study population was clinically healthy Holstein cows from a commercial dairy herd in southern Turkey. Of 109 animals, 65 cows were seropositive by ELISA and the prevalence of bovine leukemia virus (BLV) infection was 59.6%. The prevalence of seropositive cows in 2nd (62.8%), 3rd (64.7%), 4th (61.5%), and 5th (66.6 %) lactations was slightly higher than that of cows in 1st (52.6%) lactations. No statistical differences were observed between BLV seronegative and seropositive cows for production and reproduction parameters analysed in this study (P > 0.05).
Highlights
This case represents a very unusual occurrence of spirocercosis that presented as an oesophagogastric intussusception
Whilst thoracic spondylitis and aortic undulation are considered to be pathognomonic for spirococercosis, a caudal oesophageal mass has a few differential diagnoses that include gastro-oesophageal intussusception
All diagnostic tests and treatments were performed as part of the treatment of the patient and routine work. This case was unique for a number of reasons: it was a spirocercosis case that presented as an emergency due to the presence of an oesophagogastric intussusception, which caused an obstruction and blood loss
Summary
This case represents a very unusual occurrence of spirocercosis that presented as an oesophagogastric intussusception. Gastro-oesophageal intussusception is described as the invagination of the stomach into the lumen of the thoracic oesophagus (Rallis, Moraitou & Vlemmas 1995). It is an uncommon and often fatal condition in dogs and is defined as an acute emergency problem that requires immediate surgical reduction. It was thought that S. lupi provoked oesophageal neuromuscular degeneration resulting from chronic inflammation caused by the parasite and asynchronous relaxation of the lower oesophageal sphincter (Rallis et al 1995) This communication provides details of a case of oesophagogastric intussusception with a concurrent S. lupi nodule at the cardiac sphincter. The final diagnosis on post-mortem examination was an S. lupi non-neoplastic nodule in the caudal oesophagus with an oesophagogastric intussusception
