The aim of this study was to perform a follow-up evaluation of the Streptococcus mutans and Streptococcus sobrinus colonization profile of children's oral cavities, which included the pattern of vertical transmission from mother to child, genotypic diversity, and stability of the strains. The subjects were 16 mother-child pairs, who were monitored for 20 months. Samples of saliva, tongue dorsum...
In Brazil, the common bean is a crop with significant social and economic importance. The prospecting of N2 fixing bacteria crucial since biological nitrogen fixation (BNF) an eco-friendly technique. This work aimed to obtain characterize rhizobium isolates based on morpho-physiological, molecular, symbiotic efficiency parameters, using strains SEMIA 4077, 4080, 4088 as references. characterist...
To investigate the prevalence of fungal agents in local Egyptian broiler breeder chicken’s premises, tracheal and cloacal swabs from chickens, feed, and water samples were collected. The targeted breed's dead-in-shell eggs and newly hatched chick’s samples were also tested. All fungal isolates were morphologically typed and the predominant fungal species were further subjected to molecular typi...
Survey results and genotypic characterization of Escherichia coli strains demonstrate that the bacteriocins colicin Ia and microcin V coassociate in a strain more often than would be expected by chance. When these two bacteriocins co-occur, they are encoded on the same conjugative plasmid. Plasmids encoding colicin Ia and microcin V are nonrandomly distributed with respect to the genomic backgr...
