The use of fatty acid methyl esters (FAME) as biomarkers to identify groups of microorganisms was studied. A database was constructed using previously published results that identify FAME biomarkers for aerobic, anaerobic and facultatively aerobic bacteria. FAME profiles obtained from pure cultures were utilized to confirm the predicted presence of biomarkers. Principal component analysis demon...
3,3′-Diaminobenzidine was applied at doses of 5, 10, 25, and 50 mg kg−1 of soil and their effects were evaluated on indigenous soil microbial communities (viable aerobic bacteria, fungal populations, aerobic N2-fixing bacteria, denitrifying, and nitrifying bacteria), and soil enzymatic activities (acid and alkaline phosphatases, arylsulfatase, and dehydrogenase). At doses of 5 or 10 mg kg−1, 3,...
The fate of indicator bacteria, a bacterial pathogen, and total aerobic bacteria during aerobic and anaerobic digestion of wastewater sludge under laboratory conditions was determined. Correlation coefficients were calculated between physical and chemical parameters (temperature, dissolved oxygen, pH, total solids, and volatile solids) and either the daily change in bacterial numbers or the per...
Many colonic aerobic bacteria possess alcohol dehydrogenase (ADH) activity and are capable of oxidizing ethanol to acetaldehyde. Accordingly, some ingested ethanol can be metabolized in the colon in vivo via the bacteriocolonic pathway for ethanol oxidation. By diminishing the amount of aerobic colonic bacteria with ciprofloxacin treatment, we recently showed that the bacteriocolonic pathway ma...
BACKGROUND Surgical Site Infections (SSIs) are infections of incision or deep tissue at operation sites. These infections prolong hospitalization, delay wound healing, and increase the overall cost and morbidity. OBJECTIVES This study aimed to investigate anaerobic and aerobic bacteria prevalence in surgical site infections and determinate antibiotic susceptibility pattern in these isolates. ...
