The brain is assumed to be a sterile organ in the absence of disease although the impact of immune disruption is uncertain in terms of brain microbial diversity or quantity. To investigate microbial diversity and quantity in the brain, the profile of infectious agents was examined in pathologically normal and abnormal brains from persons with HIV/AIDS [HIV] (n = 12), other disease controls [ODC...
A temperature-sensitive mutant of Escherichia coli at the nonpermissive temperature fails to produce normal levels of 5 S rRNA. Instead, a number of larger RNA molecules are accumulated. One of these molecules, a 9 S RNA, contains 5 S rRNA sequences. When the strain is shifted from a nonpermissive to a permissive temperature, radioactive label is lost from the 9 S RNA and appears in 5 S rRNA. T...
BACKGROUND Marine sponge species are of significant interest to many scientific fields including marine ecology, conservation biology, genetics, host-microbe symbiosis and pharmacology. One of the most intriguing aspects of the sponge "holobiont" system is the unique physiology, interaction with microbes from the marine environment and the development of a complex commensal microbial community....
Our understanding of thermophile diversity is based predominantly on PCR studies of community DNA. "Universal" and domain-specific rRNA gene PCR primers have historically been used for the assessment of microbial diversity without adequate regard to the degree of specificity of primer pairs to different prokaryotic groups. In a reassessment of the published primers commonly used for "universal"...
Two Neisseria gonorrhoeae isolates from Seattle and two isolates from Uruguay were resistant to erythromycin (MIC, 4 to 16 microg/ml) and had reduced susceptibility to azithromycin (MIC, 1 to 4 microg/ml) due to the presence of the self-mobile rRNA methylase gene(s) ermF or ermB and ermF. The two Seattle isolates and one isolate from Uruguay were multiresistant, carrying either the 25.2-MDa tet...
