Secretome of Staphylococcus aureus
Presence of secreted proteins is the key for sustenance of Staphylococcus aureusstrains in the host system. General secretory (Sec) system is a well known and major secretion system that is responsible for the transportation of exoproteins across the bacterial cytoplasmic membrane and cell wall. In order to define the secretome of S. aureus, the availability of combination of...

Antimicrobial activities of Garcinia kola on oral Fusobacterium nucleatum and biofilm
The extracts from the root, bark and seed of Garcinia kola are currently used in traditional medicine in Nigeria. The aim of this study was to evaluate the inhibitory activity of crude extracts of G. kola on Fusobacterium nucleatum isolated from the oral cavity. Methanol and aqueous extracts were prepared from the seed and the minimal inhibitory concentration was evaluated by the...

Functional analysis of a putative transcriptional regulator gene dr2539 in Deinococcus radiodurans
The radiation resistant bacterium Deinococcus radiodurans R1 possesses a high intracellular Mn/Fe concentration ratio. Non-enzymic Mn(II) in D. radiodurans acts as an antioxidant to scavenge reactive oxygen species which contributes to its extreme radioresistance. The gene dr2539 encodes a transcriptional regulator that is predicted to be involved in regulating the transportation...

Improved purification and some properties of a novel phospholipase C from Bacillus mycoides strain 970
A novel microbial phospholipase C from Bacillus mycoides strain 970 was purified to apparent homogeneity by an improved purification process, in which DEAE-Cellulose adsorption was first used to remove bulk of dark brown impurities and then a combination of DEAE-Cellulose ion-exchange, Phenyl Sepharose hydrophobic interaction and Sephacryl S-100 gel filtration chromatography was used to separate the...

Changes in the profiles of bacteria causing spontaneous bacterial peritonitis: A recent twelve-year study
During the last 20 years, there has been the recognition of prompt diagnosis and appropriate initiation treatment of Spontaneous Bacterial Peritonitis (SBP). It has been suggested that the profile of the infections has changed, and severe infections caused by resistant bacteria species have started to emerge. In this study, 166 cirrhotic patients, with SBP, were retrospectively evaluated through positive...

The influence of prebiotics on bacteriocin synthesis using the strain Lactobacillus paracasei CMGB16
The aim of this study is to determine the effect of certain prebiotics on the synthesis of bacteriocins. The Lactobacillus paracasei CMGB16 strain producing bacteriocins was used.Escherichia coli was used as the sensitive strain. In the nutritive environment (MRS); the carbon source (glucose) was supplemented with inulin from chicory and Dahlia, raffinose and lactulose. The...

Detection of Actinobacillus actinomycetemcomitans from periodontitis and healthy individuals by culture and PCR methods
The aim of this study was to determine the detection of Actinobacillus actinomycetemcomitans from periodontitis and healthy individuals by culture and PCR methods. Clinical isolates were obtained of periodontal pockets by paper point from 50 health subjects with periodontal pockets depth < 5 mm and 50 patients with periodontitis with periodontal pockets...

Mortality of cultured koi Cyprinus carpio in Korea caused by Bothriocephalus acheilognathi
Mortality of cultured koi Cyprinus carpio occurred up to 25% at a commercial fishery in North Chungcheong Province of South Korea. Gross observations showed that long-white parasites have blocked and filled the intestine, protruding into the mouths of the fish. Histopathology of the damaged intestine was checked and the structure of the parasite was examined under scanning electron microscope (SEM)....

Analysis on clinical features and immunity in chronic hepatitis B virus infected patients with low-level HBsAg
To understand clinical features and immunity of chronic HBV-infected patients with high or low level HBsAg, the differences of serum two-component-determined circulating immune complexes (TCIC) and peripheral blood lymphocyte subsets between these patients were analyzed. 126 patients with chronic hepatitis B virus infection were divided into two groups including 44 with low-level HBsAg and 82 with high-level...

Genotypic characterisation of Echinococcus granulosus isolated from human in Turkey
Cystic echinococcosis is one of the most important zoonotic diseases in Turkey. The aim of this study was for the molecular analysis of Echinococcus granulosusisolates from different regions of Turkey. For this purpose, 46 hydatid cyst samples collected from humans during the surgery were included. The partial sequences of mitochondrial cytochrome c oxidase subunit 1 (CO1) gene was used for...

Anti- leishmanial activities of ethanolic extract of Kayseri propolis
Propolis is a natural product which honey bees collect from plants then mix it with their wax. The present study has involved the investigation of antileishmanial effect of propolis against the Leishmania tropica parasite. In this study, propolis that was used was collected from Kayseri, a city in the Middle Anatolian Region of Turkey. An ethanolic extract of propolis was obtained. The propolis...

Evidence of antimicrobial activity of date fruits in combination with high intensity ultrasound
Although dates are highly nutritious materials that may support the growth of spoilage and pathogenic organisms, they are typically safe to store at ambient temperature in a warehouse for up to several months. The goal of this research was to better understand the apparent long-term microbial stability of dates and to investigate new means to further enhance their stability. To this purpose, several different...

Bacterial contamination of water points of the upper Mfoundi watershed, Yaounde, Cameroon
More than 80% of the population of the peri-urban area of Yaoundé (Cameroon), do not have access to drinking water and resort to wells, springs and rivers to satisfy this need. The bacteriological quality of such water sources is doubtful because of their proximity to both point and diffuse sources of pollution and can thus present public health risks. In order to evaluate the bacteriological quality...

Rapid diagnosis of ETEC and HPI-harboring Escherichia coli infection in newborn piglets with diarrhea
Diarrhea is a common and important disease in industrial pig farms and the pathogenic Escherichia coli infection is the main cause of morbidity and mortality in newborn piglets. The preliminary diagnoses on this disease are mainly depending on clinical symptom and detailed body dissection. To further shorten the diagnosis time and increase the determination efficiency for newborn piglet diarrhea...
