jejuni isolates with a mutation in gyrA outcompete clonally related fluoroquinolone-sensitive C. jejuni in the absence of antibiotic selection pressure in vivo (in the chicken). This indicates that the single point mutation not only confers a high-level resistance to fluoroquinolones but also ...
The invention relates to prodrugs of N-substituted derivatives of 6-aminouracils, 6-aminoisocytosines, guanines, and 2-aminoadenines. The N-linked substituents include an ester group that is cleaved u

virulent strain (NAP1/027/B1) additionally increases the severity of the disease. Thepathophysiologyof CDAD and colitis results from a disruption of the normalbacterial floraof the colon, colonization withC. difficile, and the release of toxins that lead to mucosal damage and inflammation. CDAD ...
Antibiotic production begins with the detection and identification of antibacterial chemicals, followed by the cultivation and isolation of appropriate microbial strains. The technique of mono-cultivation or co-cultivation in the cultivating process depends on the antibacterial compounds that the strains of ...
This suggests that H. pylori era- dication treatment may strongly disrupt the immune status of the female vaginal tract. In a Chinese clinical comparative study involving 15 female patients with H. pylori infection, after undergoing standard triple therapy (rabeprazole, amoxicillin, and levofloxacin)...
Extracellular pH has been assumed to play little if any role in how bacteria respond to antibiotics and antibiotic resistance development. Here, we show that the intracellular pH of Escherichia coli equilibrates to the environmental pH following treatmen
The article begins by discussing how Dr. John Snow first recognized that cholera was a waterborne disease, using data he collected in Victorian Age London. Three prominent disease銉絘using Vibrio species: V. cholerae, V. parahaemolyticus, and V. vulnificus are then discussed in some detail in ...
However, a disturbing trend has also been noted in that, within a very short period of time following the introduction of a new antibiotic, resistance to that antibiotic begins to emerge, a factor that is becoming increasingly meaningful as the discovery of new antibiotics wanes (1-3). There...
There are several well-recognized limitations to the use of PCT as a surrogate marker of infection. It has been shown that in septic cancer patients with leukopenia PCT concentrations were lower [30]. Besides renal func- tion is a major determinant of PCT levels [10,31,32], and in ...
