Background and purpose: Transgenic rice is a type of rice that its genetic sequence has been changed to improve its quantity and quality. Bt (Bacillus thuringiensis) transgenic rice expresses Cry1Ab protein and is named Tarom Molaii. There are no studies on the effect of this type of transgenic rice on gastrointestinal health in Iran, so, this study investigated the effect of Tarom Molaii tran...
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...
The aerobic and anaerobic microbiology of surgical-site infections (SSI) following spinal fusion was retrospectively studied. This was done by reviewing the clinical and microbiological records at the Naval Hospital in Bethesda, Md., from 1980 to 1992. Aspirates of pus from 25 infection sites showed bacterial growth. Aerobic bacteria only were recovered from 9 (36%) specimens, anaerobic bacteri...
The ability of several anaerobic bacteria to hydrolyze esculin to esculetin is used by clinical microbiologists and taxonomists in the differentiation and identification of both gram-positive and gram-negative microorganisms. Conventional methods used for determining esculin hydrolysis by anaerobic bacteria require 24 to 48 h for completion. In this paper we evaluate two procedures which yield ...
Specimens from the conjunctival sacs of 92 healthy eyes were cultured on two separate occasions to determine the presence or absence of a persistent anaerobic flora. Aerobic bacteria and fungi were also studied for comparison. Of the 184 eye cultures, 112 (60.9%) contained at least one microorganism. Obligate anaerobes were recovered from 51.6% (95/184) of the cultures. Propionibacterium acnes,...
it is now generally recognized that anaerobic bacteria may be involved in most human bacterial infections that follow any form of surgery or are related to those body sites that have a large anaerobic population. anaerobes must therefore be sought in a wide variety of clinical specimens. in this study, 3015 specimens of patients (1684 male and 1331 female) with periodontitis (160 cases), abcess...
The utility of anaerobic blood culturing is often debated in the general population, but there is limited data on the modern incidence, microbiology, and utility of obtaining routine anaerobic blood cultures for burned patients. We performed a retrospective review of the burned patients electronic medical records database for all blood cultures drawn between January 1997 and September 2005. We ...
BACKGROUND Microalgae are a promising feedstock for biofuel and bioenergy production due to their high photosynthetic efficiencies, high growth rates and no need for external organic carbon supply. In this study, utilization of Chlorella vulgaris (a fresh water microalga) and Dunaliella tertiolecta (a marine microalga) biomass was tested as a feedstock for anaerobic H2 and CH4 production. RES...
Fifty patients with anaerobic sepsis were treated with intravenous and oral metronidazole. In 26 cases this was combined with other antimicrobial agents. Highly satisfactory clinical results were obtained in most patients, though in many surgical drainage was also essential. No side effects or thrombophlebitis were seen. Mixed growths of anaerobic and aerobic bacteria were isolated from all exc...
