Triatoma brasiliensis sensu lato (s.l.), the main vector of Chagas disease in northeastern Brazil, is a species complex comprising four species, one with two subspecies (T. brasiliensis brasiliensis, T. brasiliensis macromelasoma, T. juazeirensis, T. sherlocki, and T. melanica), and each taxon displaying distinct ecological requirements. In order to evaluate the genetic relationships among nine...

Shiga toxin-producing Escherichia coli (STEC) include O157:H7 and non-O157 serotypes. The public health impact of STEC infections is high because of their ability to cause severe infections. We characterized our STEC strains isolated from diarrheal and asymptomatic persons in northern and southwest Iran. The 29 STEC strains were examined for the presence of virulence genes by polymerase chain r...

Lavender Foal Syndrome (LFS) is a lethal inherited disease of horses with a suspected autosomal recessive mode of inheritance. LFS has been primarily diagnosed in a subgroup of the Arabian breed, the Egyptian Arabian horse. The condition is characterized by multiple neurological abnormalities and a dilute coat color. Candidate genes based on comparative phenotypes in mice and humans include the...

Being the third-largest primate population has not made macaque (Macaca fascicularis sp.) monkeys less exposed to threats and dangers. Despite wildlife protection, they have been widely hunted and consumed in several countries because of their purported nutritional values. In addition to trading as pure bush meats in several places, monkey meat has been sold in meatball and soup products in Ind...

Cytolethal distending toxin (CDT) consisting of CdtA, CdtB and CdtC has been reported to be a possible virulence factor of campylobacters including Campylobacter upsaliensis. In our previous study, the cdtB gene-based PCR-restriction fragment length polymorphism (RFLP) assay for detection and differentiation of 7 Campylobacter species yielded 3 different RFLP patterns (Cu-I to Cu-III). In this ...

OBJECTIVES A mutation in the JAK2 gene, V617F, has been identified in several BCR-ABL1 negative myeloproliferative neoplasms (MPN): polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). Defining the presence or absence of this mutation is an essential part of clinical diagnostic algorithms and patient management. Here, we aimed to evaluate the performance of t...

Three interferon-inducible Mx genes have been identified in rainbow trout Oncorhynchus mykiss and their roles in virus resistance have yet to be determined. In mice, expression of the Mx1 protein is associated with resistance to influenza virus. We report a study to determine whether there was a correlation between the expression of Mx in rainbow trout and resistance to a fish rhabdovirus, infe...

Electrolyzed strong acid water (ESW) containing free chlorine at various concentrations is becoming to be available in clinical settings as a disinfectant. ESW is prepared by electrolysis of a NaCl solution, and has a corrosive activity against medical instruments. Although lower concentrations of NaCl and free chlorine are desired to eliminate corrosion, the germicidal effect of ESW with low N...

Hypophosphatasia is a rare disease characterized by low serum levels of tissue non-specific alkaline phosphatase (TNSALP) and a spectrum of skeletal disease varying from the severest form with death in utero to mild with no clinical abnormality in adults. Currently, the diagnosis of hypophosphatasia is made on the basis of clinical findings, radiography, low serum alkaline phosphatase levels an...

BACKGROUND Varicella zoster virus (VZV) causes chickenpox in children and zoster (zona) in the elderly. Using RFLP-PCR method for detection of VZV specific SNPs ORF38, 54 and 62 could distinguish the profile of VZV isolates. The aim of this study was to investigate enzymatic digestion pattern of VZV ORF38 and ORF54 in chickenpox patients using RFLP technique. METHODS Thirty-eight chickenpox p...
