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]
An antimicrobial effective against Gram-negative enteric bacilli (i.e. aminoglycoside) or an anti-pseudomonal cephalosporin (i.e. cefepime) are generally added to metronidazole, and occasionally cefoxitin when treating intra-abdominal infections to provide coverage for these organisms.
Cefepime/enmetazobactam, sold under the brand name Exblifep, is a medication used for the treatment of urinary tract infections. [ 1 ] [ 2 ] It is a fixed dose combination containing cefepime , a cephalosporin antibacterial; and enmetazobactam , a beta-lactamase inhibitor .
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 ]
'Bacterium actinomycetem comitans' was first described by Klinger (1912) as coccobacillary bacteria isolated with Actinomyces from actinomycotic lesions in humans. It was reclassified as Actinobacillus actinomycetemcomitans by Topley & Wilson (1929) and as Haemophilus actinomycetemcomitans by Potts et al. (1985). The species has attracted ...
Cutaneous actinomycosis is a chronic disease that affects the deep subcutaneous tissue of the skin. Caused by an anaerobic, Gram-positive, filamentous type of bacteria in the genus Actinomyces, [1]: 270 invasion of the soft tissue leads to the formation of abnormal channels leading to the skin surface (external sinus tracts) that discharge pale yellow sulfur granules.
Actinomycosis is pathognomonic for abscesses containing "sulfur" granules, and its colonies appear basophilic with club-shaped reaction products on a histological preparation. [6] [7] Lumpy jaw is commonly treated with broad-spectrum antibiotics with varying success, [8] and can be a major economic loss for producers in countries where it is ...
Actinomyces massiliensis is a non-spore forming, non-motile, Gram-positive, rod-shaped bacterium. [1] [2] Cells measure at 0.5-1.7 μm in length and 0.35-0.74 μm in width, and they appear as straight rods. [1] [2] When plated on sheep-blood agar, colonies of A. massiliensis are circular, white, and have a glossy sheen. [1]
