•Genomic epidemiological analysis of Group B streptococcal isolates was performed using the S. agalactiae PubMLST database. •CgMLST discriminated same sequence type and, identified known and suspected case clusters. •Isolates clonal complex (CC) 17, CC23 CC19 were most common in infant, maternal non-invasive cases, respectively. •Erythromycin clindamycin resistance associated with CC1, erm(B) i...

conclusions the rate of carbapenem resistant a. baumannii isolates were high in this study. since, blaoxa-58-like or mbl genes were not detected, it seems that resistance to carbapenems is related to blaoxa-23-like and blaoxa-24-like. moreover, blaoxa-23-like was the most prevalent oxacillinase (oxa) gene. most of the isolates belonged to one of the four dominant genotypes indicating clonal dis...

BACKGROUND The association of PMQR and ESBLs in negative-bacteria isolates has been of great concern. The present study was performed to investigate the prevalence of co-transferability of oqxAB and bla CTX-M genes among the 696 Escherichia coli (E. coli) isolates from food-producing animals in South China, and to characterize these plasmids. METHODS The ESBL-encoding genes (bla(CTX-M), bla(T...

micropropagated plantlets derived from three different grape rootstock genotypes namely, dogridge (vitis champini), so4 (v. berlandieri×v. rupestris) and ari-h-144 (v. vinifera×v. labrusca) were subjected to randomly amplified polymorphic dna (rapd) and inter simple sequence repeats (issr) analyses in order to evaluate their genetic stability and/or detect likely existing variations among in vi...
