Broad-host-range IncP-1 plasmids and their resistance potential
The plasmids of the incompatibility (Inc) group IncP-1, also called IncP, as extrachromosomal genetic elements can transfer and replicate virtually in all Gram-negative bacteria. They are composed of backbone genes that encode a variety of essential functions and accessory genes that have implications for human health and environmental bioremediation. Broad-host-range IncP plasmids are known to...
متن کاملBroad host range of streptococcal macrolide resistance plasmids.
Four macrolide-lincosamide-streptogramin B resistance plasmids transferred into 13 recipients belonging to Streptococcus, Staphylococcus, and Listeria genera. The plasmids were stably maintained in all new hosts except Streptococcus sanguis, Streptococcus pneumoniae, Staphylococcus aureus, and Listeria innocua and were identical to those found in the corresponding donor strains.
متن کاملTransfer of IncP Plasmids to Extremely Acidophilic Thiobacillus thiooxidans.
The broad-host-range IncP plasmids RP4, R68.45, RP1::Tn501, and and pUB307 were transferred directly to extremely acidophilic Thiobacillus thiooxidans from Escherichia coli by conjugation at frequencies of 10 to 10 per recipient. The ability of T. thiooxidans to receive and express the antibiotic resistance markers was examined. The plasmid RP4 was transferred back to E. coli from T. thiooxidan...
متن کاملPreliminary taxonomic study of the genus Praon (Hymenoptera: Braconidae: Aphidiinae) and its host associations in Iran
در این تحقیق، اطلاعاتی در زمینهی فعالیت زمانی، پراکنش و روابط میزبانی زنبورهای پارازیتویید جنس Praon در ایران ارایه میگردد. هشت گونه از این جنس در نواحی مورد بررسی جمعآوری شد که از میان آنها چهار گونهی Praon absinthi Bignell،Praon barbatum Mackauer، Praon exsoletum (Nees)و Praon volucre (Haliday) قبلاً از ایران گزارش شده بودند و چهار گونهی دیگر شامل Praon rosaecola Starý، Praon abjectum (Ha...
متن کاملDiversification of broad host range plasmids correlates with the presence of antibiotic resistance genes.
The IncP-1ε subgroup is a recently identified phylogenetic clade within IncP-1 plasmids, which plays an important role in the spread of antibiotic resistance and degradation of xenobiotic pollutants. Here, four IncP-1ε plasmids were exogenously captured from a petroleum-contaminated habitat in China and compared phylogenetically and genomically with previously reported IncP-1ε and other IncP-1 ...
