The prevalence of human Brucellosis in Mazandaran province, Iran

Brucellosis is a bacterial infectious disease shared between human and livestock caused by a bacterium of the genus Brucella. This disease is generally transmitted to human through direct contact with an infectious animal, drinking unpasteurized milk or milk products. Symptoms include weakness, lethargy, chills, fever, sweating, decreased appetite, headache, back pain and psychological symptoms; and the main...

Frequency of Cryptosporidium infection and related factors under five year’s old children hospitalized with gastroenteritis

In recent years, Cryptosporidium has been considered, especially in children, as one of the causative agents in acute and/or chronic diarrhea. Studies had indicated that the prevalence of this protozoa is more common in children under five years old than other age groups. Therefore, determining the prevalence of Cryptosporidium in this age group is the main step to assist in designing and...

Synergistic effect of herbivory and mycorrhizal interactions on plant invasiveness

Amongst many novel interactions that alien plants forge with their new associates in the introduced range, the role of Arbuscular mycorrhizal (AM) mutualism and herbivory has been hitherto studied separately. Since these associations operate concurrently in nature to influence plant performance, we attempted to investigate their interactive effect on invasiveness of Mayweed Chamomile (Anthemis cotula L.), a highly...

Personal hygiene habituation and related factors of high school students in Gaziantep -Turkey

Hand hygiene practice has become quite an important issue among hygiene practices. Improving personal hygiene practices leads to decrease in the occurrence of many infectious diseases. A total of 1370 students in 36 classes in 9 schools in Gaziantep were included in this study by “size proportional systematic sampling” and “basic randomized sampling” techniques. A data collection form termed as...

Characterization of a cytochrome P450 monooxygenase gene involved in the biosynthesis of geosmin in Penicillium expansum

Geosmin is a terpenoid, an earthy-smelling substance associated with off-flavors in water and wine. The biosynthesis of geosmin is well characterized in bacteria, but little is known about its production in eukaryotes, especially in filamentous fungi. The origin of geosmin in grapevine is largely attributable to the presence of Penicillium expansum on grapes. Herein, we describe the characterization of...

σ32 regulation of the algA and pnrB expression in Pseudomonas sp. HK-6 which degrades the explosive hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX)

Several live vaccines have been introduced so far to protect brucellosis but they have not been adopted broadly or their use has been discontinued for a variety of reasons. Immunity against facultative intracellular bacterial pathogen depends on acquired cell mediated immunity, distinguished by the activation of T-lymphocytes and subsequent activation of macrophages for increased killing of such intracellular pathogens....

In vitro antimicrobial activities of 26 Yunnan plant extracts against multi-drug resistant pathogens

In vitro activities of 80% ethanol extracts from 26 plants native to South-Eastern Yunnan, China, were evaluated against clinical multi-drug resistant (MDR) pathogens. The extracts were initially screened by the agar hole diffusion test. Then the minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) or minimum fungicidal concentration (MFCs) were determined through serial dilution...

Seroprevalence and risk factors of African horse sickness in mules and donkeys in selected sites of West Amhara Region, Ethiopia

The study was conducted with the aims of determining the seroprevalence and risk factors of African Horse Sickness (AHS) in mules and donkeys in selected sites of West Amhara region. A total of 390 (191 mules and 199 donkeys) serum samples were collected from November, 2009 to February, 2010. Blocking ELISA was employed to determine the presence of African Horse Sickness Virus (AHSV) antibodies. The overall...

Expression of recombinant Hepatitis C virus (HCV) Core, E1 and E2 proteins by the baculovirus expression vector system

Hepatitis C virus (HCV) infection is definitely a global severe health problem. Neither a vaccine to prevent the infection nor an effective treatment for all HCV genotypes is available at the present time. The prophylactic HCV vaccine researches are recently focusing on eliciting antibody responses to three highly immunogenic structural proteins containing core protein (C) and envelope glycoproteins E1 and E2. The...

Effects of macro-parasitic mite Eutrombidium trigonum (Hermann) on the life history characteristics of Hieroglyphus species from Sindh, Pakistan

Trombidiidae species are reported as ecto-parasites in their larval stages for the variety of acrididae, which are pests of many economic crops in the world including Pakistan. The current parasitism ratio of red mite, Eutrombidium trigonum, was studied on three host species of Hieroglyphus, which are presently destroying valued crops. It was observed that proportional survival was found to be lower...

Identification of Candida species isolated from hospital acquired infections cases and hospital indoor environments

In this study it has been shown that hospital sources of Candida species could cause human infections, via identification of the yeasts isolated from cases and also environmental specimens, staff, visitors and patient’s micro flora. Microscopic direct examination was used for detection of Candida pathogenic forms. Differential cultures and molecular tests including; PCR and RFLP were performed...

Identification and function of LPS induced tumor necrosis factor-alpha (LITAF) gene from Crassostrea ariakensis stimulated by Rickettsia-like organism

LPS induced tumor necrosis factor-alpha (LITAF) plays a role in regulating the expression of TNF-α. The present study was undertaken to identify a gene, Ca-LITAF, from oysterCrassostrea ariakensis challenged with rickettsia-likea organism (RLO). The full-length cDNA consists of 750 bp with an ORF encoding 115 amino acid residues. Amino acid sequence analysis revealed that Ca-LITAF shared...

Trachoma knowledge in Southern Khorassan, Iran

Trachoma is a keratoconjunctivitis that causes ocular infection with Chlamydia trachomatis (Ct). The chronicity and reinfection leads to increasingly severe inflammation that can damage the conjunctiva and cornea. The WHO (World Health Organization) is in alliance with the Global Elimination of Trachoma by 2020. This safe strategy includes: surgery for trichiasis, antibiotics for active trachoma, facial cleanliness, and...

σ32 regulation of the algA and pnrB expression in Pseudomonas sp. HK-6 which degrades the explosive hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX)

Pseudomonas sp. HK-6 cells can utilize hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) as a carbon and nitrogen source. HK-6 cells grown in media containing RDX express several genes encoding stress shock proteins (SSPs) and enzymes that function in RDX degradation. The rpoH gene (σ32, a stress response sigma factor), alg operon (clustered genes for alginate synthesis)...
