Anaerobic infections are caused by anaerobic bacteria. Obligately anaerobic bacteria do not grow on solid media in room air (0.04% carbon dioxide and 21% oxygen); facultatively anaerobic bacteria can grow in the presence or absence of air. Microaerophilic bacteria do not grow at all aerobically or grow poorly, but grow better under 10% carbon ...
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Anaerobic gram-positive cocci are frequently isolated from anaerobically infected bones and joints., they accounted for 40% of anaerobic isolates of osteomyelitis caused by anaerobic bacteria and 20% of anaerobic isolates of arthritis caused by anaerobic bacteria. P magnus and P prevotii are the predominant bone and joint isolates.
The thrombophlebitis is a serious condition and may lead to further systemic complications such as bacteria in the blood or septic emboli. Lemierre's syndrome occurs most often when a bacterial (e.g., Fusobacterium necrophorum) throat infection progresses to the formation of a peritonsillar abscess. Deep in the abscess, anaerobic bacteria can ...
Eikenella corrodens is a Gram-negative facultative anaerobic bacillus that can cause severe invasive disease in humans. [1] It was first identified by M. Eiken in 1958, who called it Bacteroides corrodens. [2] E. corrodens is a rare pericarditis associated pathogen. [3]
Fusobacterium is a genus of obligate anaerobic, Gram-negative, [2] non-sporeforming bacteria [3] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. [4] [5] Fusobacterium was discovered in 1900 by Courmont and Cade and is common in the flora of humans. [6] [7]
According to the Florida Department of Public Health, there have been a record 65 infections this year caused by Vibrio vulnificus — a species of bacteria found in warm, brackish water ...
Pseudomonas can, in rare circumstances, cause community-acquired pneumonias, [39] as well as ventilator-associated pneumonias, being one of the most common agents isolated in several studies. [40] Pyocyanin is a virulence factor of the bacteria and has been known to cause death in C. elegans by oxidative stress.
