GRAM-positive bacteriaWOUND infectionsANTIBIOTICSHOSPITALSINFECTION controlEPIDEMIOLOGYGUIDELINESBackground: The emergence and spread of drug-resistant pathogens continue to threaten the ability to treat common infections. Thus, the current antimicrobial resistance (AMR) survey seeks to present th...
This gene confers resistance to several medically-important antibiotics including linezolid, which is often prescribed to treat Gram-positive infections such as vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA). Another gene, fosA, is also of clinical significance...
Enterococcus faecalis is a gram-positive bacterium that can cause a variety ofnosocomial infectionsof which urinary tract infections are the most common. These infections can be exceptionally difficult to treat because of drug resistance of many E. faecalis isolates. Is enterococcus a UTI? Enterococci...
Clostridium difficile is a type of bacteria that causes infection in the large intestine. It is gram-positive, spore-forming bacillus and anaerobic bacteria. It causes serious diarrhea and abdominal cramping in human beings.Answer and Explanation: ...
Enterococcus species are gram-positive bacteria that are abundant in the gastrointestinal tract of a wide range of animals [47]. In humans, Enterococci are one of the earliest colonizers in the gut. Currently, more than 50 species of Enterococcus have been identified. However, a few species are...
Diletta Collalto1, Veronica Schiaffi2, Valentina Pastore2, Paolo Visca1,3, Fiorentina Ascenzioni2, Giordano Rampioni1,3 & Livia Leoni1* In Gram-negative pathogens, the stringent response regulator DksA controls the expression of hundreds of genes, including virulence-related ...
The trend was similar regardless of Gram-positive or Gram-negative status, rod or coccus shape, or the ability of the cells to express appendages under the conditions tested. Bacterial attachment correlates with surface–bacteria interaction forces Previously, we found strong evidence of a correlation...
False positive results have been well documented when using the EIA and SAT, as the Brucella S-LPS antigen does show some cross-reactivity with other Gram negative bacteria includ- ing Yersinia enterocolitica, Vibrio cholerae, Eschericha coli, and Francisella tularensis.9,10 Most cross-reacting ...
This specific binding to the promoter regions of phoP and pbgPE confirmed that the phosphorylated form of PhoP is the active isoform and revealed that PhoP is involved in positive feedback control of its own expression (Fig. 3A). Concomitant overexpression of genes involved in resistance, ...
We report the NMR structure and functional characterization of the transfer protein TraH encoded by the conjugative Gram-positive broad-host range plasmid pIP501. The structure exhibits a striking similarity to VirB8 proteins of Gram-negative secretion systems where they play an essential role in ...
