Arcanobacterium haemolyticum has an established role in the etiology of human pharyngitis. There are increasing reports of systemic infections caused by this organism. From India, we report the first case of Arcanobacterium haemolyticum causing pyothorax in an immunocompetent adolescent male patient. The probable mode of infection is also discussed. The role of A. hemolyticum as an animal patho...

Epstein-Barr virus (EBV) encodes 49 microRNAs (miRNAs) in the BART and BHRF1 regions of its genome. Although expression profiles of EBV-encoded miRNAs have been reported for EBV-positive cell lines and nasopharyngeal carcinoma, to date there is little information about total miRNA expression, including cellular and viral miRNAs, in the primary tumors of EBV-associated B-lymphoproliferative diso...

Pyothorax is a potentially recurrent condition that results in systemic illness. Treatment is intended to eliminate infection, improve ventilation, and minimize recurrence. Decision-making challenges presented to the clinician dealing with the dog with pyothorax relate to both work-up and therapy, i.e., what imaging modality is most appropriate and when is surgery indicated? Various reports of ...

A 16-month-old Holstein heifer with a history of anorexia and respiratory distress was referred to the Veterinary Research and Teaching Hospital of Tehran University. Heart and lung sounds were inaudible on the left side but greatly increased on the right side. On electrocardiography (ECG), decreased amplitudes of ECG parameters were observed. Ultrasonography results revealed a pleural effusion...

A 27-month-old female cat was presented with septic peritonitis secondary to a ruptured pyometra and subsequent pyothorax. Vasopressor-refractory septic shock led to a suspicion of critical illness-related corticosteroid insufficiency, successfully treated with intravenous hydrocortisone. Previous megestrol acetate administration may have played a role in the development of adrenocortical dysfu...
