Esophageal obstruction due to trichobezoar in a she-camel (Camelus dromedarius).

Background: Occurrences of esophageal foreign bodies are common in camels. Esophageal obstruction in camels due to bezoars is rare. Case Description: This report describes esophageal obstruction in camel due to trichobezoar. A 2-year-old she-camel presented with a history of inability to swallow and there was food and water regurgitation for one day before. Radiography and endoscopic examination revealed an oval-shaped foreign body embedded in the esophageal lumen in the level distal third of the neck. The foreign body was successfully removed using cervical esophagotomy under general anesthesia. Successful esophagostomy revealed trichobezoar weighing 45 g and measuring 85 mm × 75 mm × 42 mm. The trichobezoar removed from the esophagus was the cause of esophageal obstruction. Conclusion: Esophageal obstruction in camel could be due to trichobezoar. Radiography and endoscopy are valuable diagnostic methods to determine the position and nature of an obstructive object.

Contagious caprine pleuropneumonia: The first isolation and molecular characterization of Mycoplasma capricolum subsp. capripneumoniae in the Kingdom of Saudi Arabia.

Classical contagious caprine pleuropneumonia is one of the most fatal contagious disease of goats listed by World Organization for Animal Health that leads to major economic losses. It is caused by infection with Mycoplasma capricolum subspecies capripneumoniae. In order to isolate the causative agents of CCPP for the first time in the Kingdom of Saudi Arabia, fifteen flocks from Eastern region (Al Ahsa, Dammam and Hafr Albaten) and ten flocks from Riyadh and Al-Kharj regions were selected for this study. A total of 700 samples (400 nasal swabs, 300 pleural fluid samples and lung samples (from necropsied animals)) were collected from goats showing typical signs of CCPP. The clinical signs of diseased cases revealed serous to mucoid nasal discharge, coughing, dyspnea, frothy salivation, and fever (40-42°C). Necropsied animals showed fibrinous pleuropneumonia and increased pleural fluid. Of 400 nasal swabs, 190 pleural fluid, and 110 lung samples, 26 (6.5%), 31 (16.3%) and 19 (17.3%) Mycoplasma isolates were recovered, respectively. Biochemically, all isolates were sensitive to digitonin and fermented glucose. Sixty seven of Mycoplasma isolates were belonged to Mycoplasma mycoides cluster based on detection of 16S rRNA. Polymerase chain reaction screening of Mycoplasma isolates using specific primer for M. capricolum subsp. capripneumoniae confirmed 55 isolates to be M. capricolum subsp. capripneumoniae.
