Specimens from the ileum, colon and rectum were aseptically collected from 50 consecutive horse carcases submitted for necropsy to the Department of Pathology, Faculty of Veterinary Science, University of Pretoria. These were bacteriologically examined for the presence of Salmonella. Seventeen of these were positive for Salmonella at one or more sites. Serotyping of the isolates revealed a dominance of Salmonella Hayindogo in these horses.

Background: In horses, systemic calcinosis is a rare syndrome characterised by muscle lesion associated with the mineralisation of large muscle groups or other organs, in the absence of an alternative cause for the calcification, such as toxic, enzootic or metabolic. Molecular and histopathological aspects of the disease are still poorly elucidated.
Objectives: To describe the epidemiological, pathological and molecular aspects of systemic calcinosis in a convenience sample of six horses submitted to necropsy in the Southern and Midwestern regions of Brazil.

Acute esophageal necrosis (AEN), also known as black esophagus or Gurvits syndrome, is an uncommon endoscopic finding characterized by diffuse, circumferential, black discoloration of the esophagus that terminates at the gastroesophageal junction. The incidence of AEN has been reported to be 0-0.2% in autopsy series and up to 0.

Animal tuberculosis (TB) has been reported in several wildlife species in the Greater Kruger Conservation Area (GKCA), South Africa. This report describes the discovery of clinical tuberculosis, caused by (), in free-ranging vervet monkeys (). The "One Health" concept is especially relevant to TB since this is a multi-host disease with zoonotic potential and is endemic in GKCA.

The clinical manifestation of intracranial mycotic aneurysms (ICMAs), which are rare but carry high risks of rupture and early mortality, remains poorly understood. We present a case of an ICMA that rapidly developed and ruptured after the diagnosis of meningitis caused by (), which rarely causes bacterial meningitis. A 54-year-old man presented with a headache that worsened on coughing, without altered consciousness or vomiting.

When encountering severe hypoxemia that does not respond to oxygen supplementation, it is essential to consider underlying right-to-left shunting. Among various diagnostic approaches, the microbubble test via transthoracic echocardiography (TTE) is a simple, noninvasive method for detecting pulmonary arteriovenous shunts, particularly in hepatopulmonary syndrome (HPS). Although microbubbles are usually administered peripherally, using a Swan-Ganz (SG) catheter to inject microbubbles directly into the pulmonary artery may provide even more definitive diagnostic information.
