Campylobacter jejuni is one of the most common bacterial causes of human gastroenteritis, and recent findings suggest that turkeys are an important reservoir for this organism. In this study, 80 C. jejuni isolates from eastern North Carolina were characterized for resistance to nine antimicrobials, and strain types were determined by fla typing, pulsed-field gel electrophoresis (PFGE) with SmaI...

a study was conducted to assess the durable resistance in a near isogenic line of spring wheat (triticum aestivalis l.), possessing resistance gene yr-18 to some isolates (race specific resistance) of stripe rust (puccinia striiformis f. sp. tritici), namely thatcher yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...

Colistin is reintroduced into therapeutic protocols as one of the last resort antibiotics against multidrug-resistant (MDR) pathogens. In February 2019, International Consensus Guidelines (ICG 2019) on optimizing administration colistin has for first time stipulated an official recommendation higher dosing regimen based pharmacokinetic/pharmacodynamic (PK/PD) modeling data. This study aimed at ...

Methods Over 10 weeks in 2010, 250 prospectively recruited admissions to a busy, ring fenced JR unit underwent admission screening for MRSA and demographic screening using a standardised questionnaire based on the unit’s admission policy which is designed to exclude patients at high risk of MRSA colonisation. Subjects comprised of patients admitted for reasons other than JR surgery, as well as ...

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has become a major problem in US hospitals already dealing with high levels of hospital-associated MRSA (HA-MRSA). Using antimicrobial drug susceptibility data for 1999-2006 from The Surveillance Network, we characterized the relationship between outpatient and inpatient levels of CA-MRSA nationally. In outpatients, the ...

Methods In this prospective cohort study in 50 pig farms in The Netherlands, human nasal samples were collected on 5 time points in 8 months. At start of the study, throat samples and environmental samples were taken. Persistent carriers were defined as persons with 100% of nasal samples positive for MRSA, non-carriers had no MRSA and intermittent carriers had at least one positive sample. Data...

the purposes of this research were to the evaluation of resistance to nickel and cadmium in 52 indigenous and non-indigenous strains of contaminated soils and a study of growth promoting characteristics of some resistant isolates. resistance test at three levels of cadmium (0, 100, 200 mg l-1) and five levels of nickel (0, 250, 500, 750, 1000 mg l-1) in the framework of a completely randomized ...

Resistant (Taim, RS) and susceptible albino (Joinville, SC) Biomphalaria tenagophila populations were kept together, at different proportions, throughout a 18-month-period. Some of the snail groups were submitted to Schistosoma mansoni infection. The targets of this study were (a) to analyze the populational dynamics among resistant and susceptible individuals to S. mansoni; (b) to study the re...
