BACKGROUND To determine the effect of opium smoking cessation on the frequency and type of microorganisms in the nasopharynx of opium smokers. METHODS This was a cross-sectional study performed in psychology and ENT department of Moradi Hospital of Rafsanjan University of Medical Sciences in 2008 (Kerman, Iran). Nasopharyngeal cultures were taken from 50 opium smokers before and 2 to 3 months...

OBJECTIVE Conventional diagnosis of bacterial vaginosis contains some controversial points. To understand accurately the relationship between clinical stages and the microbiotas, the intravaginal microbial flora was analyzed by the clone library method. STUDY DESIGN Vaginal fluid samples from 31 patients were examined. Lactobacillary grade, Nugent score, culture-based method, and clone librar...

F ollowing the serendipitous discovery of penicillin in 1928 and streptomycin in 1943, the pharmaceutical industry has been screening thousands of soil samples for antimicrobial agents produced by inhabitant microbes. Chloramphenicol, clavulanic acid, erythromycin, gentamicin, rifampin, teicho-planin, tetracycline, and vancomycin represent only a few products of this spectacularly successful ef...

We studied the microbial flora in decomposing mangrove leaves in relation to changes in nitrogen and tannin levels, and in penaeid prawn assemblages. Senescent leaves of two mangrove species (Rhizophora apiculata and Avicennia marina) kept in nylon bags, were separately immersed for 80 days in five tanks full of mangrove water. A known amount of decomposing leaves was collected every ten days f...

The Lactobacillus (Doderlein's bacillus) (Wilson and Miles, 1964) had been regarded as the preponderant micro-organism in the vagina, at least after puberty. During the 1960s a re-examination of the microbiology of the vagina was prompted by the widespread use of potent antibacterial agents and of oral contraceptives (Krupp and St. Romain, 1960; Morris and Morris, 1967; Morris, 1969). During th...

The present study is aimed at evaluating the effect of functional alginate coating incorporated with Lactoperoxidase (LPOS) and Zataria multiflora Essential Oil (ZEO) or both as natural additives on microbial and chemical characteristics of rainbow trout fillets. Firstly, Different treatments of trout fillets were prepared using ZEO (0.5 and 1%) and LPOS (5%) individually and in combination...

A prospective study was carried out on patients with diabetic foot lesions to determine their clinical characteristics, the spectrum of aerobic microbial flora and to assess their comparative in vitro susceptibility to the commonly used antibiotics. A total of 157 organisms (143 bacteria and 14 fungi) were isolated and an average of 1.52 isolates per case was reported. Polymicrobial infection w...
