The anisakid nematodes morphologically corresponding with Pseudoterranova decipiens sensu lato (s.l.) (Krabbe, 1878) from different seal or sea lion hosts and geographical origins, previously identified as Pseudoterranova krabbei, P. decipiens (s.s.), P. bulbosa, P. azarasi and P. cattani by multilocus enzyme electrophoresis, were characterized using a DNA approach. Also a population of P. deci...

The increasing incidence of Multi Drug Resistance Tuberculosis (MDR-TB) and Extensively Drug Resistance TB (XDR-TB) worldwide highlight the urgent need to search for newer anti-tuberculosis compounds. It has been determined that pharmaceutical plant, hops (Humulus lupulus), possesses some antibacterial effect. In this study, the antimycobacterial effect of this plant on rifampin sensitive and r...

A new molecular biological approach for the identification of bacteria is described. This approach employs PCR of bacterial cell lysates with conserved primers located in the 16S rRNA sequence flanking a variable region, and analysis of the amplified product was based on the principle of single-strand conformation polymorphism (SSCP). The PCR product was denatured and separated on a nondenaturi...

Leptospirosis, a disease with protean manifestations, is caused by Leptospira species. Early and reliable identification of Leptospira serovars remains to be a challenge due to diversity at serovar level. The potential of polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) was assessed for detection of sequence variation in pathogenic specific 631 bp fragment of 16S r...

Escherichia coli was used to investigate quinolone resistance and mutations in gyrA gene of E. coli isolated from pet (dog and cat), human (pet's owner), vegetable and edible ice in Bangkok and vicinity. Susceptibility test for nalidixic acid (NA) showed similar percent resistance among the sample sources but a lower ciprofloxacin (CIP) resistance was found particularly in human source. Mutatio...

INTRODUCTION The aim of this work was to evaluate the prevalence of Mycobacterium tuberculosis (MT) strains with mutations that could result in resistance to the main drugs used in treatment in a region with one of the highest numbers of tuberculosis (TB) cases in southern Brazil. METHODS Deoxyribonucleic acid (DNA) from 120 sputum samples from different patients suspicious of pulmonary tuber...

Hepatitis C virus (HCV) populations in vivo consist of heterogeneous mixtures of genetically different but closely related variants defined as a 'quasispecies'. The longitudinal fluctuation of HCV quasispecies populations in chronic hepatitis C has not been elucidated. Serial plasma samples were obtained from four patients with chronic hepatitis C (two patients without any treatment and two pat...
