Escherichia coli also known as E. coli are gram-negative facultative anaerobic, rod-shaped, Coliform bacteria, commonly found in the lower intestine of warm-blooded organisms. This study was designed to determine the antibiotic susceptibility and the phenotypic detection of AmpC beta-lactamase producing Escherichia coli from the urine of students attending FuLafia Clinic, Nasarawa State, Nigeria. A total of 22 urine samples were collected from the students. Eleven (50%) E...

Agroforestry systems (SAFs) are an alternative for sustainable development as they enable the recovery of degraded areas and reduce deforestation, contributing to breaking the cycle of traditional family farming, so common in the Amazon region, which enables the recovery of soils, the increase of organic matter and soil fertility. Cocoa beans are grown and fermented in SAFs. According to the research, the significant appearance of endophytic microorganisms such as fungi in the cocoa bean can ben...

The objective of the study is to detect the resonant absorption of an ultrahigh-frequency electromagnetic field in the centimeter range by DNA molecules at a frequency corresponding to the natural frequency of torsional vibrations of the DNA helix. Instead of DNA solution, cultures of various bacteria containing DNA were used, for whose DNA spirals the resonant frequencies of torsional vibrations were calculated. The cultures were placed in test tubes or cuvette and irradiated by microwave gener...

Fenjiu-flavour Daqu is an important starter to support growth of microorganisms in the fermented process of Fenjiu-flavor liquor. A novel thermophilic microorganism, designated strain gby1, was isolated from Fenjiu-flavour Daqu from Shanxi Xinghuacun Fenjiu Distillery Company Limited, Fenyang country, Shanxi province. The morphological, physiological, chemical taxonomic and phylogenetic characteristics of the strain were described in this paper. The isolate gby1 exhibited higher heat resistance....

Introduction: Food contamination with microorganisms can occur at any stage of the process, from food production to consumption, and can be the result of environmental contamination. This study was carried out in order to identify the microorganisms forming the flora and to determine the level of microbial contamination of the internal surfaces of devices in the cold chain of butcher shops. Method: This is a comparative cross-sectional descriptive study of 30 internal surfaces of ten devices in ...

Background: Vaginal microbiota dysbiosis could lead to the vaginal health conditions. This imbalance in vaginal microbiota can be due to a number of factors including contraceptive methods. Objective: This study was carrried out to investigate the vaginal microbiota dysbiosis and associated vaginal health outcomes among women under contraception at Musasa health Center. Materials and Methods: This was a cross sectional study. 56 vaginal swab samples were collected from women enrolled in a family...

Purpose: Our study focused on Pied Grow and Cattle Egret, two commensal and ubiquitous birds feeding in dumps and frequenting our homes. Our aim was to identify the bacteria that birds bring to our homes and could be a potential risk to Congolese health. Method: We have done bacteriological analyses of bird feces for to explore its gut microbiota composition. The feces were collected in the uricotelic cloaca by using a swab in 52 Cattle Egrets (Bubulcus ibis) and 23 Pied Crows (Corvus albus) cap...

Alpha-amylase is a starch hydrolyzing enzyme which has many industrial applications. In this study, Bacillus subtilis QM3 has ability to produce α-amylase. Identification was done by iodine test, based on the clear zone around the sample in starch agar plates. Alpha-amylase activity was measured using 3,5-dinitrosalicylic acid (DNS). The result showed B. subtilis QM3 can produce α-amylase and activity of α-amylase was 50.58 IU/mL. The study on enzymatic properties was found: the optimum temperat...

The negatively charged coordination groups on the structure of these biomolecules, which is the main components of extracellular polymeric substances (EPS), have good adsorption efficiency for heavy metals. In this paper, EPS form Proteiniphilum acetatigenes PSB-W which was extracted by EDTA method, and the effects of pH, EPS dosage, adsorption time and initial metal concentration on the adsorption regularity of Cu2 and Pb2 ions on EPS structure were studied respectively, as well as the adsorp...

Background: The proclivity of bacteria resistance to antibiotics has led researchers to develop more interest in antibiotics efficiency in tackling bacterial infections. As part of the effort to finding final resolutions to antibiotics effectiveness, this study was conducted to ascertain the antibiotic sensitivity pattern of three bacterial strains, this study was carried out from March 2019 to June 2019, using different antibiotics such as Ampicillin (AMP), Tetracycline (TET), Erythromycin (ERY...
