Antibiotic resistance in gonorrhea Antibiotic resistance in gonorrhea The Gonorrhea bacterium Neisseria gonorrhoeae has developed antibiotic resistance to many antibiotics. The bacteria was first identified in 1879, although some Biblical scholars believe that references to the disease can be found as early as Parshat Metzora of the Old Testament. In the 1940s effective treatment with penicillin became available, but by the 1970s resistant strains predominated. Resistance to penicillin has developed through two mechanisms: chromasomally mediated resistance (CMRNG) and penicillinase-mediated resistance (PPNG). CMRNG involves step wise mutation of penA, which codes for the penicillin-binding protein (PBP-2); mtr, which encodes an efflux pump that removes penicillin
Antibiotic-associated diarrhea an infection caused by the probiotic supplements. "Clostridium difficile", also known more commonly as "C. diff", is known to account for 10 to 20 percent of antibiotic-associated diarrhea cases. The reasoning for this, is that the antibiotics administered for the treatment of certain diseases processes such as inflammatory colitis also inadvertently kills a large portion of the gut flora, the normal flora that is usually present within the bowel. With this lower amount of "healthy" bacteria present, the overgrowth of "C. diff" is then responsible "for elaborating the enterotoxin". Antibiotic-associated diarrhea Antibiotic-associated diarrhea (AAD) results from an imbalance in the
