The structure of a fosmid consists of several key components: an origin of replication, a selectable marker (usually an antibiotic resistance gene), and cloned DNA fragments. The combination of these elements allows for the maintenance and propagation of large DNA inserts within host cells. Construction Process The process of constructing a fosmid library begins with the ...
Isolated in 1949 in Japan from a fermented culture of Paenibacillus polymyxa, colistin was first used clinically in 1959 under the trade name Cortisporin®. ...
As such, four isolates were tdh+ (1%) and another four were trh+ (1%). No evidence of pandemic clones was detected using group-specific PCR (GS-PCR). ...
The purpose of this study was to investigate the susceptibility of waterborne strains of Legionella to eight antimicrobials commonly used in legionellosis therapy. The minimum inhibitory concentrations (MICs) of 66 environmental Legionella strains, isolated from fountains and cooling towers of public facilities (hotels, schools, and shopping malls) in Macau and Guangzhou, were tested using ...
River water samples were taken from 32 locations around the basin of Chaophraya River and its four major tributaries in Thailand to investigate resistance ratios of Escherichia coli isolates to eight antibiotic agents of amoxicillin, sulfamethoxazole/trimethoprim, tetracycline, doxytetracycline, ciprofloxacin, levofloxacin, norfloxacin and ofloxacin. ...
Tolerance of antibiotic susceptible and antibiotic resistant Escherichia coli, Enterococcus and Staphylococcus strains from clinical and wastewater samples against ozone was tested to investigate if ozone, a strong oxidant applied for advanced wastewater treatment, will affect the release of antibiotic resistant bacteria into the aquatic ...
The antibiotic and heavy metal resistance profiles of the isolates were determined by using 26 antibiotics and 17 heavy metals. Acinetobacter isolates displayed resistance to β-lactams, cephalosporins, aminoglycosides, and sulfonamides. The hemolytic isolates were found to show resistance to higher numbers ...
Antibiotics are widely used in both human and veterinary medicine and antibiotic-resistant bacteria cause problems in antibiotic therapy. ...
Effluents from 37 lagoons were assayed for the presence of Escherichia coli, Campylobacter, Listeria, and Salmonella. Antibiotic resistance profiles were determined by the Kirby-Bauer swab method for 12 antibiotics comprising eight classes. Statistical analyses indicated that farm type influenced the amount and type of resistance, with nurseries and sow farms ...
This study evaluated the presence of both fecal coliforms and Escherichia coli O157:H7 at five sites in rural and urban areas in the eastern part of the Wildcat Creek watershed. Escherichia coli O157:H7 was isolated by immunomagnetic separation. Shiga-like toxin genes (stx1 and stx2) were detected in selected isolates by polymerase chain reaction (PCR) ...
Shigellosis is an acute gastroenteritis caused by Shigella species. Forty isolates of Shigella spp. were obtained from the river Narmada during 20052006. ...
In what has become an all-too-common trend, antibiotic-resistant isolates emerged soon after the large-scale use of penicillin to treat bacterial infections (7). This cycle has been repeated many times over the years as new antibiotics are generated (reviewed in reference 66). This has led to obvious concern about the continuing efficacy of ...
