The effect of different solvents and pollutants on the cellular fatty acid composition of three bacterial strains: Thauera aromatica, Geobacter sulfurreducens and Desulfococcus multivorans, representatives of diverse predominant anaerobic metabolisms was investigated. As the prevailing adaptive mechanism in cells of T. aromatica and G. sulfurreducens whose cellular fatty acids patterns were dom...

This case study with chart review describes the aerobic and anaerobic microbiology of specimens obtained from 47 patients with Aspergillus spp fungus ball. Bacteria were recovered from 32 of the 47 (68%) patients. Eighty-six isolates, 29 aerobic and facultatives and 57 anaerobic, were recovered. Aerobic and facultatives only were recovered in 6 instances (19% of culture-positive specimens), ana...

PURPOSE Clinical, epidemiological and microbiological examinations of adult patients with periodontal disease. MATERIAL AND METHODS The study of population consisted of 21 subjects (13 female and 8 male) aged 38-58 years, treated in the Outpatient Department of Periodontology. Dental examinations were performed at an artificial light and using a WHO periodontometer, a mirror and a probe. Peri...

objective: this study was undertaken with an aim to determine bacterial species involved in post partum infections and also their abundance in patients admitted to at khanevadeh hospital. in this study out of three different kinds of postpartum infections (i.e. genital, breast and urinary tract), only genital infection is considered. materials and methods:  post partum infection among 6077 pati...

AIM The aim of this study was to investigate anaerobic and aerobic bacteria profile and determination of antibiotic susceptibility pattern in aerobic bacteria. METHOD Specimens were cultured using optimal aerobic and anaerobic microbiological techniques. Identification of bacterial isolates was performed by standard microbiological methods and antibiotic susceptibility testing was performed a...

To characterize the effects of pentachlorophenol (PCP) on the performance and microbial community of aerobic granular sludge in sequencing batch reactor (SBR), the web-based terminal restriction fragment length polymorphism (T-RFLP) and real-time PCR (RT-PCR) techniques were used to explore the bacterial community structure. When PCP increased from 0 to 50 mg/L, the COD removal rate changed lit...

A survey on organisms able to use molecular hydrogen as electron donor in the energy-yielding process is presented. In the group of the aerobic hydrogen-oxidizing bacteria so far two types of hydrogenases have been encountered, a NAD-reducing, soluble enzyme (H2 : NAD oxidoreductase) and a membrane-bound enzyme unable to reduce pyridine nucleotides. With respect to the distribution of both type...

The objective of the study was to find the antimicrobial effect of local brands of toothpastes containing different active ingredients, against aerobic and anaerobic oral flora and Streptococcus mutans; the causative agent of dental caries and dental plaque. The efficacy of eight locally formulated dentifrices was checked against aerobic and anaerobic oral bacteria of 30 subjects. Sterilized sw...

The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while synthesizing or accumulating organic sol...

classification of various microbial agents. Molecular methods have helped to better define organism groupings and have led to considerable changes in bacterial nomenclature. The primary purpose of nomenclature is to permit us to know as exactly as possible what another clinician, microbiologist, epidemiologist, or investigator is referring to when describing an organism responsible for infectin...
