salmonella is one of the most important zoonotic pathogens with many virulence factors playing a major role in its pathogenesis. the aims of this study were to detect spva, int2 and invc virulence genes of different salmonella serotypes isolated from various clinical animal and human sources, and to investigate antibiotic resistance patterns among these serotypes. using a pcr assay, a total of ...
in modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as tem-1, tem-2, and shv-1 are transferred among bacterial species. the genes coding the production of esbl are of...
One hundred and fourteen strains of Pasteurella multocida were isolated from different domestic animals species (cattle, buffalo, sheep, goat, pig, rabbit, dog, cat), avian species (chicken, duck, turkey) and wild animals (deer, tiger, orang utan, marmoset). The serogroups of P. multocida were determined by both conventional capsular serotyping and a multiplex PCR assay targeting specific capsu...
Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has gained popularity in recent years for rapid bacterial identification, mostly at the genus or species level. In this study, a rapid method to identify the Escherichia coli flagellar antigen (H antigen) at the subspecies level was developed using a MALDI-TOF MS platform with high specificity and sensit...
A serotyping assay for hepatitis C virus (HCV) was evaluated with samples from Thailand, where the distribution of HCV genotypes was different from that in Western countries where the assay was designed and validated. The sensitivity of the assay was low (58%) for HCV RNA-positive samples compared to that of the genotyping assay (95%, P < 0.01). In addition, only 36% of anti-HCV-positive but HC...
Modifications to the tube-agglutination procedure which Schaefer developed for serotyping of organisms of the Mycobacterium avium-M. intracellulare-M. scrofulaceum complex are proposed.
conclusions our study illustrates the importance of constantly monitoring the prevalent serotypes in any region in order to aid in the development of more effective vaccines. results our results revealed that in egypt, currently, the most prevalent serotypes were serogroup 6 and serotype 19f as they represented 58% of all isolates. high rates of resistance were found to different antibiotic cla...
Background: The World Health Organization views dengue fever as a significant worldwide public health threat in the tropics and subtropics. Dengue virus has four serotypes, DENG 1 to 4, which were responsible for outbreaks that occurred other parts of world from 1980s until now. Aims Objectives: Clinical manifestations molecular serological studies help determine inflammatory response events as...
