Actinomyces spp. and Eubacterium nodatum are often recovered in infections associated with intrauterine devices. Mobiluncus spp. can be associated with bacterial vaginosis. [ 34 ] The aerobic bacteria also found mixed with these anaerobic bacteria include Enterobacteriaceae, Streptococcus spp. (including groups A and B), Neisseria gonorrhoeae ...
Actinomyces is a genus of the Actinomycetia class of bacteria. They all are Gram-positive and facultatively anaerobic , growing best under anaerobic conditions. [ 2 ] Actinomyces species may form endospores , and while individual bacteria are rod-shaped , Actinomyces colonies form fungus -like branched networks of hyphae . [ 3 ]
Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria, with greater activity against both types of organism than third-generation agents. A 2007 meta-analysis suggested when data of trials were combined, mortality was increased in people treated with cefepime compared with other β-lactam antibiotics. [1]
Schaalia turicensis (formerly Actinomyces turicensis) is a Gram-positive bacterium found in the flora of the oral cavity, gut, skin, and female urogenital tract. [2] S. turicensis is an important human pathogen of soft tissue infections in the lower body. [3] S. turicensis is a facultative anaerobe, growing in air and CO 2 conditions.
Actinomyces and its associated species have, for a long time, been implicated in human infections, particularly those of the mouth, pharynx, distal esophagus, and genitourinary tract. [9] Within the last 10 years, A. massiliensis has been detected in blood, and most Actinomyces bacteremias stem from oral sources. [9]
Nocardia as found on a brain biopsy.. Nocardia is a genus of weakly staining Gram-positive, catalase-positive, rod-shaped bacteria.It forms partially acid-fast beaded branching filaments (appearing similar to fungi, but being truly bacteria).
Actinomyces bovis is a branching, Gram-positive, rod-shaped bacterium of the genus Actinomyces. [1] It is the causative agent of lumpy jaw in cattle, and occasionally causes actinomycosis infections in humans. [ 3 ]
Actinomycetales can be found mostly in soil and decaying organic matter, as well as in living organisms such as humans and animals. They form symbiotic nitrogen fixing associations with over 200 species of plants, and can also serve as growth promoting or biocontrol agents, or cause disease in some species of plants.
