Cephalosporin-Resistant Gonorrhea in North America

Cephalosporin-resistant gonorrhea in North America.

GONORRHEA HAS AFFECTED HUMANS FOR CENTUries and remains common. Worldwide, an estimated 106.1 million cases occur annually. In 2011, gonorrhea again was the second most commonly reported notifiable infection in the United States with 321 849 cases reported. Because gonorrhea often can be asymptomatic, the true disease burden may be closer to 700 000. Gonorrhea disproportionately affects racial,...

Molecular Characterization of Extended-Spectrum-Cephalosporin-Resistant Enterobacteriaceae from Wild Kelp Gulls in South America.

Extended-spectrum-cephalosporin-resistant Enterobacteriaceae are a public health concern due to limited treatment options. Here, we report on the occurrence and the molecular characteristics of extended-spectrum-cephalosporin-resistant Enterobacteriaceae recovered from wild birds (kelp gulls). Our results revealed kelp gulls as a reservoir of various extended-spectrum cephalosporinase genes ass...

Antimicrobial-resistant strains of Clostridium difficile from North America.

A total of 316 toxigenic Clostridium difficile clinical isolates of known PCR ribotypes from patients in North America were screened for resistance to clindamycin, metronidazole, moxifloxacin, and rifampin. Clindamycin resistance was observed among 16 different ribotypes, with ribotypes 017, 053, and 078 showing the highest proportions of resistance. All isolates were susceptible to metronidazo...

Admixture in North America

The history of North America has been marked by the encounter of populations from different continents. The discovery of the New World began a period defined by human migrations at a much larger scale than in previous history. This movement of people, voluntary or forced, changed profoundly the human landscape. As populations came into contact, admixture followed in varying degrees depending on...
