Use of spirulina (Arthrospira fusiformis) for promoting growth of Nile Tilapia fingerlings
In the present investigation, spirulina (Arthrospira fusiformis) was used as feed additives on growth performance in Nile Tilapia (Oreochromis niloticus). A. fusiformis was isolated from various rook pool of a rocky shore, Alexandria and Kafr El-Sheikh Governorates, Egypt. The results showed that the optimum medium, pH and temperature for the growth protein and chlorophyll-a content of A....

The diagnostic role of indirect fluorescence antibody in csytic echinococcus and the role of western blot in following-up patients with csytic echinococcus after surgery
Cystic echinococcosis (CE) is a complicated zoonotic infection with diagnosis and treatment. In this study, we aimed to determine the diagnostic performance parameters of Indirect Fluorescence Antibody (IFA) method and also the usability of Western Blot (WB) method for following up CE cases by detecting the antigenic patterns. Cases diagnosed as CE in General Surgery Department of Cerahpasa Faculty of medicine and a...

Effects of exogenous secreted protein acidic and rich in cysteine on human lens epithelial cell proliferation and adhesion
Many factors can impact human lens epithelium biological behavior. Secreted protein acidic and rich in cysteine (SPARC) is a newly discovered protein that can impact cell activity and may potentially affect human lens epithelial cells (HLECs). HLEC (SRA01/04) proliferation was detected by methyl thiazolyl tetrazolium (MTT) and the proliferation index was assessed by flow cytometry with SPARC at concentrations of 0, 0.2,...

Molecular diversity of bacterial community of dye wastewater in an anaerobic sequencing batch reactor
Anaerobic sequencing batch reactor has proven more effective than aerobic systems in treating dye-containing wastewaters which usually contain refractory dyes and organic chemicals. In this study, the composition and diversity of bacterial community present in an anaerobic sequencing batch reactor used for treating dye wastewater were determined by both high-through pyrosequencing and screening environmentally derived...

Molecular identification of four Salmonella serovars isolated from food in Tunisia based on the sequence of the ribosomal RNA genes
In this study, the 5′-end of the 16S-23S intergenic spacer regions and domains II and III of the 23S ribosomal DNA (rDNA) of six Salmonella strains were analyzed. These strains belong to four serovars: Agona, Amesterdam, Corvallis and Enteritidis, and were isolated from food samples. Polymerase chain reaction (PCR) products were then sequenced on both strands and the sequences obtained were aligned using...

Isolation and characterization of an antimicrobial endophytic bacterium ME-2 from mulberry twig in China
An antimicrobial endophytic bacterium strain, ME-2, was isolated from fresh mulberry twig tissues, and was identified. In addition, antimicrobial activities of the isolated strain were evaluated against Bacillus thuringiensis, Escherichia coli, Staphylococcus aureus,Beauveria bassiana and Mycoid bacillus using the antagonism test method. The results showed that, strain ME-2 was...

Medicinal and culinary herbs as environmentally safe inhibitors of dangerous toxinogenic plant and human fungal pathogens
The need for new antifungal substances and alternative antifungal treatments is becoming more and more obvious. One of the most promising and ecologically safe possibilities could be based on taking advantage of a plant’s natural antifungal properties. This work presents the results of extensive screening experiments focused on the antifungal inhibitory effect of 49 plant species against 6 dangerous toxinogenic...

Effect of deleting acetic acid-producing key enzyme gene of Selenomonas ruminantium on the ruminal fermentation in vitro
The aims of this study were to examine the effects of the engineering bacteria TnK6 (The deleting acetic acid-producing key enzyme gene of Selenomonas ruminantium) on ruminal fermentation in vitro. The mixed culture of ruminal bacteria (ruminal fluids from the healthy sheep), buffer, and primarily degradable substrates were inoculated with equal number of S. ruminantium K6 and its engineering...

Crude methanolic extract activity from rinds and seeds of native durian (Durio zibethinus) against Escherichia coli and Staphylococcus aureus
This study was conducted to determine the activity of the methanolic crude extracts collected from the seeds and rinds of native durian (Durio zibethinus) against hospital isolates of Escherichia coli and Staphylococcus aureus. The fruit samples were collected from a local durian dealer and subjected to rotary evaporator. Using the Kirby-Bauer disc diffusion technique, the crude extracts with...

Probiotic properties of Brevibacillus brevis and its influence on sea bass (Dicentrarchus labrax) larval rearing
Efficacy of Brevibacillus brevis strain and its influence on larval rearing of sea bass (Dicentrarchus labrax) were investigated in the present work. Biochemical analyses permit to identify this strain as B. brevis. This bacterium has an inhibitory effect against fish pathogenic bacteria, especially the genus of Vibrio. Enzymatic characterization revealed that B. brevis was lipase positive,...

Investigation of bluetongue virus in Kurdish sheep in Kurdistan province of Iran
Bluetongue (BT) is a noncontagious disease caused by an Orbivirus of the Reoviridaefamily. The virus is transmitted by arthropods of the genus Culicoides and its distribution worldwide is restricted to the regions that contain competent vectors. This study was conducted to determine the seroprevalence and molecular serotypes of bluetongue virus (BTV) of Kurdish sheep in Kurdistan province during...
