penicillin resistances การใช้

• The highest rate of penicillin resistance, 32 percent, occurred in children under 5.
• She was one of the pioneers in this field, documenting the phenomenon of penicillin resistance early on.
• No instance of penicillin resistance has been reported to date, although since 1985, many reports of penicillin tolerance have been made.
• The rapid development of penicillin resistance by staphylococci led to its being fast-tracked for approval by the Food and Drug Administration in 1958.
• While CDC says the anthrax so far is susceptible to penicillin, preliminary tests suggest it also may contain an early signal of developing penicillin resistance.
• It was one of the earlier bacteria in which penicillin resistance was found in 1947, just four years after the drug started being mass-produced.
• As with the penicillin resistance, the " penB " ( porin formation ) and " mtr " ( efflux pump formation ) mutations mediate chromosomal resistance.
• In 1947, she published her best-known work, on penicillin resistance in " staphylocci ", proving that the bacteria were becoming more resistant to the drug over time, using the new technique of phage typing.
• Penicillin resistance rose from 21.7 percent of strep strains in 1996 to 26.6 percent in 1999, and for erythromycin it increased from 10.8 percent to 20.2 percent, the team reports in a paper appearing in Monday's online edition of the journal Nature Medicine.
• Health authorities throughout the nation have been concerned for several years about signs of a gradual increase in penicillin resistance among S . pneumoniae bacteria, which annually account for 3, 000 cases of meningitis, 50, 000 cases of blood infections, 500, 000 cases of pneumonia and more than 7 million childhood ear infections.
• Health authorities throughout the nation have been concerned for several years about signs of a gradual increase in penicillin resistance among S . pneumoniae bacteria, which annually account for about 3, 000 cases of meningitis, 50, 000 cases of blood infections, 500, 000 cases of pneumonia and more than 7 million childhood ear infections.
• Recently, resistance to even vancomycin has been shown in some strains of " S . aureus " ( sometimes referred to as vancomycin resistant " S . aureus " ( VRSA ) or vancomycin intermediate-resistance " S . aureus " ( VISA ) ) often coinciding with methicillin / penicillin resistance, prompting the inclusion of newer antibiotics ( such as linezolid ) that have shown efficacy in highly drug-resistant strains.
