Catalase-negative Staphylococcus aureus: a rare cause of catheter-related bacteremia

Characterization of a Catalase-Negative Methicillin-Resistant Staphylococcus aureus Strain

“…However, none of them has been characterized with molecular methods (1,2,7,10,12). We here describe a catalase-negative methicillin-resistant S. aureus (MRSA) isolate that was characterized by amplification and sequencing of the putative catalase gene.…”

First Report of Septicemia Caused by an Obligately Anaerobic Staphylococcus aureus Infection in a Human

“…Though catalase activity has been proposed to play a role in the virulence of S. aureus subsp. aureus (11), severe human infections by catalase-negative S. aureus have been reported in the literature (2,6,10). There was no obvious underlying illness that predisposed him to such a dramatic multisystemic infection.…”

Morel’s Disease and Caseous Lymphadenitis: a Literature Review with Special Reference to Saudi Arabia

“…Sheep and goats are also the main hosts of MD [9,8,25,26]. Saan infection was also reported in one case of a dog [27] and a few human cases [28,29,30,31].…”

“…Cases of Saan infection in humans are very few [28,29,30,31]. The first report of Saan from a human was in a patient presenting with septicemia, septic arthritis, and multiple pulmonary abscesses [31].…”
