Beta-Lactam Resistance in Anaerobic Bacteria: a Review

Journal of Chemotherapy, 1996
The majority of the human microflora consists of anaerobic bacteria. Normally these bacteria have low pathogenicity, but under certain conditions, such as destruction of tissues and poor circulation or impaired host defense, they may cause serious infections. Bacteroides species are the most frequently isolated microorganisms from suppurative anaerobic

Oropharyngeal tularemia in beta lactam-resistant cervical lymphadenitis

The Turkish Journal of Ear Nose and Throat, 2011
This study aims emphasize oropharyngeal tularemia in the differential diagnosis of infected lymphadenopathy in the neck region.Twenty patients (13 males, 7 females; mean age 23 years; range 9 to 43 years) diagnosed with tularemia among those who admitted to our clinic between October 2008 - October 2010 with the complaint of lymphadenopathy in the neck,

Identifying Beta-Lactam Resistance with Neural Networks

2019 IEEE International Conference on Bioinformatics and Biomedicine (BIBM), 2019
Antibiotic resistant bacteria are an ever-present threat in today's society and matter of great concern for the medical and scientific communities. With the high frequency of mutations, and the ability to transfer genes across species, bacteria can acquire resistance to currently used antibiotics.

Chromosomal beta-lactam resistance in enterobacteria.

Scandinavian journal of infectious diseases. Supplementum, 1987
Most enterobacterial species carry a chromosomal ampC beta-lactamase gene. In Escherichia coli and Shigella, expression from ampC is non-inducible and the beta-lactamase is synthesized at low levels. Mutations leading to increased beta-lactamase synthesis occur rather infrequently, making resistance to modern cephalosporins a rare event in these ...

Mechanisms of resistance of enterococci to beta-lactam antibiotics

European Journal of Clinical Microbiology & Infectious Diseases, 1990
Two mechanisms are responsible for resistance of enterococci to beta-lactam antibiotics: alterations of penicillin-binding proteins and production of a beta-lactamase. The latter has been found in a few clinical isolates of Enterococcus faecalis, whereas the former appears to account for resistance in most strains.

Resistance to beta-lactam antibiotics.

Cellular and molecular life sciences : CMLS, 2004
beta-lactams have a long history in the treatment of infectious diseases, though their use has been and continues to be confounded by the development of resistance in target organisms. beta-lactamases, particularly in Gram-negative pathogens, are a major determinant of this resistance, although alterations in the beta-lactam targets, the penicillin ...

Tigecycline: The answer to beta-lactam and fluoroquinolone resistance?

Journal of Infection, 2006
Patients with serious bacterial infections such as intra-abdominal infections and complicated skin and soft tissue infections are often treated empirically because a delay in appropriate initial antimicrobial therapy has been shown to significantly increase morbidity and mortality.

Mechanisms of resistance to beta-lactam antibiotics.

Chemioterapia : international journal of the Mediterranean Society of Chemotherapy, 1985
The complex mechanism of resistance towards beta-lactam antibiotics in Gram-negative bacteria can be described by a simple equation in which the hydrolytic activity of the enzyme, the affinity to the penicillin binding protein in competition to the affinity to the beta-lactamase, the quantity of the enzyme and the ability of the drug to penetrate the ...

Resistance to beta-lactam antibiotics Proteus strains.

Acta microbiologica Polonica. Series A: Microbiologia generalis, 1976
A total of 218 Proteus strains isolated from clinical sources were tested for their susceptibility to three penicillins and two cephalosporins. The ability to beta-lactamase production was examined in 36 of these strains. Proteus mirabilis strains were generally more susceptible to cephalosporins than to penicillins, whereas indole-positive Protei were
