To establish a definite diagnosis for pulmonary hydatid disease, combination of radiology and serology is useful. In this study, 19 preoperative sera from patients with surgically confirmed pulmonary hydatidosis, 40 sera from patients with other parasitosis and pulmonary diseases, and 20 sera from healthy donors were evaluated using 4 different serological tests, i.e., the commercial ELISA (ELI...

BACKGROUND Haemophilus influenzae type b (Hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. Enzyme-linked immunosorbent assay (ELISA) technique is the most used method to detect antibodies against H. influenzae. Available commercial ELISA kits are expensive and not always readily available, particularly for epidemiological studies. OBJECTIVES T...

A commercial kit intended for Taq polymerase inhibitor removal was tested to detect Shiga-toxigenic Escherichia coli (STEC) by polymersase chain reaction (PCR) directly from cattle fecal samples. Forty-five samples were analysed for the presence of stx genes. Results were compared to those obtained by two other methods: amplification of DNA purified by a non-commercial procedure (heat lysis pro...

this report describes the histological and immunohistochemical features of a small intestinal tumor that resembled a human gastrointestinal stromal tumor (gists) in a seven-year-old male cross-breed dog. this was unique because of the expression of desmin by the tumor. grossly, the white-gray tumor measured 8.0 × 4.0 × 6.5 cm and was 760 gram in weight. it was cystic and enveloped the jejunum. ...

BACKGROUND Mycobacterium bovis is the aetiological agent of bovine tuberculosis (bTB), an important recrudescent zoonosis, significantly increasing in British herds in recent years. Wildlife reservoirs have been identified for this disease but the mode of transmission to cattle remains unclear. There is evidence that viable M. bovis cells can survive in soil and faeces for over a year. METHOD...

DNA barcodes are short sequences of nucleotides that differ from species to species (Hebert et al., 2003; Hebert & Gregory, 2005). DNA barcoding is very important in helping to reconstruct phylogenetic trees and to confirm the identity of threatened or endangered species in the wild. Additionally, it has become increasingly popular in the food industry to test the accuracy of the food being sol...

BACKGROUND The influence of diet on intestinal microflora has been investigated mainly using conventional microbiological approaches. Although these studies have advanced knowledge on human intestinal microflora, it is imperative that new methods are applied to facilitate scientific progress. Culture-independent molecular fingerprinting method of Polymerase Chain Reaction and Denaturing Gradien...

background and objectives: the obligate intracellular bacterium chlamydia trachomatis causes sexually transmissible diseases in human. timely and sensitive detection of this pathogen is very important. there are many cross-reactions in bacteriological and serological methods in detection of this type of pathogens. the aim of this study was to achieve a more specific antigen for serological test...

INTRODUCTION: This study aimed to evaluate a new commercial kit, Kit SIRE Nitratase-PlastLabor, for testing the drug susceptibility of clinical Mycobacterium tuberculosis isolates. METHODS: The accuracy of the Kit SIRE Nitratase was evaluated by examining the susceptibility (streptomycin, isoniazid, rifampicin, and ethambutol) of 40 M. tuberculosis isolates, using the proportion method with L...
