Salmonella enterica serovar Heidelberg strains are frequently associated with food-borne illness, with recent isolates showing higher rates of resistance to multiple antimicrobial agents. One hundred eighty S. enterica serovar Heidelberg isolates, collected from turkey-associated production and processing sources, were tested for antimicrobial susceptibility and compared by pulsed-field gel ele...

Antibiotics are an essential part of modern medicine. The emergence of antibiotic-resistant mutants among bacteria is seemingly inevitable, and results, within a few decades, in decreased efficacy and withdrawal of the antibiotic from widespread usage. The traditional answer to this problem has been to introduce new antibiotics that kill the resistant mutants. For the treatment of infectious di...

Bt-cotton germplasm, consisting of 75 genotypes was evaluated against cotton leaf curl disease (CLCuD) under high inoculum pressure in the field and using graft inoculation in glasshouse by visual symptom scoring assessments. None of the tested genotype was found disease free under both evaluation tests. Under field conditions in 2011, 3 genotypes were found resistant, 4 moderately resistant, 3...

The objective of this study was to conduct allelic tests including crosses between a group of rust resistant genotypes from Embrapa’s soybean germplasm collection and PI 230970 and PI 459025, which carry the Rpp2 and Rpp4 genes, respectively. Asian Soybean rust (ASR) caused by the fungus Phakopsora pachyrhizi has resulted in signifi cant yield losses and concern among Brazilian farmers. Until r...

Retail poultry products are known sources of antibiotic-resistant Escherichia , a major human health concern. Consumers have a range of choices for coli poultry, including conventional, organic, kosher, and raised without antibiotics (RWA)-designations that are perceived to indicate differences in quality and safety. However, whether these categories vary in the frequency of contamination with ...

behaviour studies indicated that the permethrin resistant strin of an. stephensi was 3-fold resistant to knock-down compared with the susceptible strain. the resistant strain was however 3-fold less irritable to permethrin and less responsive than the susceptible strain to the movement of an aspirator. if reduced irritability and reduced responsiveness to catch are consequences of the changes i...

from june 1992 to march 1993, a group of patients suffering from different types of warts were treated with intralesional injections of bleomycin sulfate. this study reviews the literature concerning this modality of treatment and the pathophysiology and immunohistopathology of warts and options for treatment. in this prospective study, a combination of a i mg/ml solution of bleomycin in distil...

Retail poultry products are known sources of antibiotic-resistant Escherichia coli, a major human health concern. Consumers have a range of choices for poultry, including conventional, organic, kosher, and raised without antibiotics (RWA) - designations that are perceived to indicate differences in quality and safety. However, whether these categories vary in the frequency of contamination with...

Nowadays the extensive use of antibiotics for the treatment of humans and warm blooded animals has influenced the frequency and spread of antibiotic resistant E. coli O157:H7 in different aqueous sources. Thus, the main aim of this study was to evaluate the antibiotic susceptibilities of E. coli O157:H7 isolated from different water sources and establish a correlation between the presence of vi...

PURPOSE Systematic evaluation of published evidence-base of the efficacy of five antiepileptic drugs - lacosamide, levetiracetam, valproate, phenytoin and phenobarbital - in convulsive benzodiazepine-resistant status epilepticus. METHODS Data sources included electronic databases, personal communication, and back tracing of references in pertinent studies. These were prospective and retrospec...
