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

Abstract

In this case report, we describe the first instance of septicemia caused by an obligately anaerobic Staphylococcus aureus in a human. A 45-year-old man presented with septicemia, septic arthritis, and multiple pulmonary abscesses, which were caused by an obligately anaerobic S. aureus. The clinical and microbiological features that led to the diagnosis are discussed. Genotyping cannot at present reliably separate S. aureus subsp. aureus from S. aureus subsp. anaerobius, but phenotypic characteristics suggest that the present isolate is a previously undescribed strain of anaerobic Staphylococcus aureus.

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].…”

“…The first report of Saan from a human was in a patient presenting with septicemia, septic arthritis, and multiple pulmonary abscesses [31]. It is believed that the cases in humans are much underestimated.…”

Staphylococcus aureus subsp. anaerobius strain ST1464 genome sequence

“…Morel's disease was described in Sudan, Saudi Arabia, Hungary, Spain, Denmark, Italy and Poland [1][2][3][4][5][6][7]. The only report of human infection was a case of septicemia in an Australian patient [8]. The causative agent of the disease is clonal and most of Morel's disease cases in the world are due to oxacillin-susceptible S. aureus subsp.…”

The catalase gene differentiates between some strains of Staphylococcus aureus ssp. anaerobius

“…Although these bacteria are considered nonpathogenic for humans, a report on a case of septicemia due to one strain of these bacteria in man has recently been published (Peake et al 2006). These bacteria were separated from other S. aureus bacteria in a subspecies (S. aureus ssp.…”
