Isolation and purification of the peptides from Apostichopus japonicus and evaluation of its antibacterial and antitumor activities

Peptides were isolated and purified from enteron of the Apostichopus japonicus (A. japonicus) by methanol and gel filtration chromatography. The antibacterial activity test in vitro was carried out by the agar diffusion method. The minimal inhibitory concentration (MIC) of the antimicrobial peptides to Escherichia coli (E. coli), Staphylococcus aureus (Sa), Vibrio harveyi (Vh), Vibrio parahemolyticus (Vp), Bacillus...

Management of root rot of pea (Pisum sativum L.) through bioagents

Root rot of pea is assuming the status of major disease in Kashmir. The diseased plants showed poor growth, yellowing and drying of foliage with partially or fully damaged root system. The pathogen associated with the disease was identified as Fusarium solani f.sp.pisi (Jones) Synder and Hansen. The dual culture studies of four biocontrol agents revealed that Trichoderma harzianum exhibited...

Efficiency of entomopathogenic fungi in the control of eggs of the brown planthopper Nilaparvata lugens Stål (Homopera: Delphacidae)

The brown planthopper, Nilaparvata lugens Stål (Homopera: Delphacidae), is an important pest of rice. Although current research indicates that the fungus can infect the adult and nymph, there is no information on the efficacy of entomopathogenic fungi against the egg. In this study, the virulence of two isolates of Metarhizium anisopliae, and six isolates ofBeauveria to N. lugens egg...

Characterization of microorganisms in the soils with sewage irrigations

The purpose of this study was to examine the influence of sewage irrigation on the quantity and distribution of soil microorganisms, and to explore the relationship between the content of soil nutrients and the quantity of different microorganism. The results showed that the quantities of the soil actinomycetes, fungi, nitrite oxidizing bacteria (NOB), nitrate bacteria (NB) and denitrifying bacteria (DB) were...

Response of Acacia senegal (L.) Willd. seedlings and soil bio-functioning to inoculation with arbuscular mycorrhizal fungi, rhizobia and Pseudomonas fluorescens

(L.) Willd. Acacia senegal is a multipurpose legume that is economically and ecologically important in Sahelian areas. The effects of arbuscular mycorrhizal fungal (AMF) inoculum (M) individually and in combination with rhizobia (R) and Pseudomonas fluorescens (Pf) were investigated on the growth and nutrition of A. senegal seedlings. In glasshouse conditions, all the inocula except...

Suitability of camel milk to transformation in Leben by lactic starter

The aim of this work was to study the suitability of camel milk to transformation in Leben by lactic fermentation. Sixty strains of lactic acid bacteria (LAB) were isolated from camel milk. Strains were tested for their acidification activity, ability to use citrate, biomass yield, growth rate and Exopolysaccharide (EPS) production. Twenty-nine strains showed ability to use citrate. These strains were tested for their...

Arbuscular mycorrhizal fungi in degraded lands in Northeast Brazil

The arbuscular mycorrhizal (AM) fungi status of degraded lands in Northeast Brazil was surveyed. The survey was conducted out at the following four sites: native vegetation (NV), moderately degraded land (LDL), highly degraded land (HDL) and land under restoration for four years (RL). At each site, soil samples were collected at 0 to 20 cm depth during September 2010. We analyzed the correlation between spores...

Molecular characterization of enterococcus strains isolated from cases of neonatal sepsis in neonatal intensive care unit

This work aimed at determining the occurrence, species prevalence, antibacterial resistance, and genetic characteristics of vancomycin-resistant enterococci (VRE) isolated from cases of neonatal sepsis at neonatal intensive care unit (NICU). Out of 134 blood samples of neonatal sepsis enterococci were isolated from 111 cases. Of these 111 strains VRE strains were identified and the resistance...

Study on immunogenicity of combined sheep and goat pox and peste des petitis ruminants vaccines in small ruminants in Ethiopia

The study was conducted at the National Veterinary Institute (NVI), Ethiopia, with the objective of evaluating the immunogenicity of combined peste des petits ruminants (PPR) and sheep and goat pox (SGP) vaccines under laboratory and field conditions for possible use of a cost efficient vaccine based disease control strategy. Vaccines of PPR and SGP were prepared using PPR75/1 (LK6 Vero74) and Kenyan sheep and goat pox...

Aeromonas veronii infection in the cultured snakehead fish, Ophiocephalus argus (Cantor)

Aeromonas veronii has been identified as a causative agent of fish and human disease outbreaks. However, there is no definitive data on A. veronii infection in cultured snakehead fish Ophiocephalus argus (Cantor). In this study, a virulent strain S-L was isolated from the farmed snakehead fish suffering from epizootic ulcerative syndrome, and identified as an A. veronii strain using...

Procalcitonin to diagnose pediatric acute bacterial enteritis

Acute enteric infections cause mortality and many cases of stunted growth in children worldwide. Acute bacterial enteritis is diagnosed by stool culture, which takes several days, though appropriate antibiotic treatment is promptly required. A faster diagnostic marker is needed. Since procalcitonin can rapidly diagnose sepsis, we sought to determine its utility for rapidly diagnosing pediatric acute enteric...
