conclusions etec and eaggec were the most detected e. coli among stool and uti samples, emphasizing the need to dedicate more health care attention to this group. in addition, our phylogenetic study may be helpful in figuring out the infection origin and for epidemiological studies. nonetheless, more research studies with larger sample sizes are suggested for confirming our results. results ove...

We present the multiplex PCR data for the presence/absence of genes involved in OTA and FB2 biosynthesis in Aspergillus niger/Aspergillus welwitschiae strains isolated from different food substrates in Brazil. Among the 175 strains analyzed, four mPCR profiles were found: Profile 1 (17%) highlights strains harboring in their genome the pks, radH and the fum8 genes. Profile 2 (3.5%) highlights s...

The aim of the study was the molecular characterisation of the aetiological agent responsible for the outbreak of swine influenza with mild respiratory tract disorders, which occurred in piglet sector in 2008. RT-nested-PCR for the detection of the conservative region of the matrix 1 gene and subsequently multiplex PCRs were performed to detect HA and NA genes. The amplified mPCR products were ...

Streptococcus agalactiae (group B streptococcus [GBS]) is the most common cause of neonatal sepsis (9). Penicillin is used for intrapartum prophylaxis, but erythromycin or clindamycin is recommended for patients allergic to penicillin (3). There are two major mechanisms of erythromycin resistance in S. agalactiae, (i) erythromycin ribosomal methylase, mediated by ermB, ermA, ermTR, or ermC, whi...

A multiplex PCR (mPCR) assay was developed for the detection of multiple Salmonella serotypes in different kind of food products. To increase specificity of this molecular method, three sets of oligonucleotide primer were used to detect the most prevalent salmonella species. PhoP primers specific to the PhoP/PhoQ loci of coliform pathogenic bacteria such as Salmonella, Escherichia coli and citr...
