Mycobacterium tuberculosis is a species of pathogenic bacteria that is responsible for causing the infectious disease tuberculosis (TB). TB is a contagious disease that primarily affects the lungs but can also affect other parts of the body. It is spread through the air when an infected person coughs, sneezes, or talks.Bacteroides is a genus of Gram-negative, obligate anaerobic bacteria. Bacteroides species are non endospore -forming bacilli, and may be either motile or nonmotile, depending on the species. [3] The DNA base composition is 40–48% GC. Unusual in bacterial organisms, Bacteroides membranes contain sphingolipids.B. fragilis strains can exhibit differences in the degree of IgA binding [ 19 ], which has been shown to influence mucosal colonization [ …Summary. Streptococcus agalactiae, also known as group B streptococcus, is a gram-positive, beta-hemolytic, catalase-negative, and bacitracin -resistant bacterium, which can cause several infections in humans. Most frequently, Streptococcus agalactiae causes neonatal infections like pneumonia, sepsis, meningitis, and septic arthritis.

Bacteroides fragilis is an anaerobic, Gram-negative, pleomorphic to rod-shaped bacterium.

Bacteroides species are anaerobic bacteria that are predominant components of the bacterial florae of mucous membranes [ 2] and are therefore a common cause of endogenous infections. [ 1] Bacteroides infections can develop in all body sites, including the CNS, the head, the neck, the chest, the abdomen, the pelvis, the skin, and the soft tissues.The consensus recognition sequence of σ ABfr was deduced by manual inspection of 23 promoter sequences in B. fragilis as ‘TAnnTTTG’ at the –7 region and a ‘TTTG’ motif at around the ...Bacteroides fragilis infection is a polymicrobial or mixed type infection. The patients having intra-abdominal infections are at high risk to have B. fragilis infection. Diabetic patients are also susceptible to infections caused by B. fragilis. Diagnosis.

Clostridium difficile is currently the leading cause of nosocomial infection. Antibiotics remain the first-line therapy for C. difficile-associated diseases (CDAD), despite the risks of resistance promotion and further gut microbiota perturbation. Notably, the abundance of Bacteroides fragilis was reported to be significantly decreased in CDAD patients. This study aimed to clarify the ...Oct 27, 2022 · Although B fragilis has long been considered reliably susceptible to a number of broad-spectrum antianaerobic drugs, these cases suggest clinicians should no longer rely on cumulative susceptibility data from surveys alone to direct treatment and should consider requesting susceptibility testing when treating serious infections caused by B ...

B. fragilis can play a dichotomous role in its interactions with the host. The non-toxigenic B. fragilis (NTBF) type strain NCTC 9343 directs a tolerogenic immune response, suppressing intestinal inflammation in mice [22,25]. However, enterotoxigenic B. nfl coverage map tvdaily tribune news cartersvilletnt duper flying machine Bacteroides xylanisolvens, such as B. fragilis, has been shown to increase the production of antibodies (IgM), against Thomsen–Friedenreich (TFα) antigen, in a dose- and time-dependent manner [50]. The increased TFα-specific antibodies would prompt the host immune response, for the immune surveillance against tumorigenic cells present in ...Background & objective:. Bacteroides fragilis is a Gram-negative anaerobic opportunistic pathogen which is managed by empirical anaerobic coverage as a hospital norm. However, with rising reports of resistance among B. fragilis strains, antibiotic susceptibility testing for this pathogen may be the only way to understand the magnitude of the problem.
