Campylobacteriosis is the most prevalent bacterial foodborne gastroenteritis affecting humans in European Union. Human cases are mainly due to Campylobacter jejuni or coli , and contamination associated with handling and/or consumption of poultry meat. In fact, constitutes bacteria’s main reservoir. A promising way decreasing incidence campylobacteriosis would be decrease avian colonization. Poultry vaccination potential for this purpose. However, despite many studies, there currently no...

Cancer does not occur in all ethnic and racial groups at similar rates. In addition, responses to treatment also vary certain groups. For Hispanics, the overall cancer incidence is generally lower yet for some specific tumor types, rates are higher compared other populations.Although disparities recognized outcomes prevention methodologies Hispanics minority populations, recruiting reporting of minorities remains a challenge. order circumvent this problem, Therapy Research Center (CTRC) has...

The Hispanic population is the fastest growing demographic group in United States and expected to triple from 46.7 million 132.8 by 2050.1 Hispanics suffer major health disparities, they have low participation cancer screening prevention programs higher incidence rates for cancers of cervix, stomach, liver, gall bladder compared with non-Hispanic whites.1,2 Despite compelling impact on as evident death 17,400 men 15,800 women a result malignancy 2012 alone, data enrollment onto...

Dermatophilus congolensis is the pathogenic actinomycete that causes dermatophilosis in cattle, lumpy wool sheep and rain scald horses. Phenotypic variation between isolates has previously been described, but its genetic basis, extent importance have not investigated. Standard DNA extraction methods are always successful for D. due to complex life cycle, one stage of which encapsulated. Here we describe development rapid reliable random amplified polymorphic (RAPD) can be used genotyping...

This study aimed to evaluate molecular typing methods useful for standardization of strains in experimental work on dermatophilosis. Fifty Dermatophilus congolensis isolates, collected from sheep, cattle, horse and a deer, were analyzed by randomly amplified polymorphic DNA (RAPD) method using twenty-one different primers, the results compared with those obtained pulsed field gel electrophoresis (PFGE) restriction digest enzyme Sse8387I. The typeability, reproducibility discriminatory power...

A partial amino acid sequence of a serine protease from Dermatophilus congolensis allowed the design oligonucleotide primers that were complemented with additional ones previously published sequences gene encoding enzyme. The polymerase chain reaction (PCR), using combinations specific and degenerate primers, amplification 1738-bp internal fragment gene, which was finally characterised by inverse PCR as first full-length sequenced (nasp) congolensis. deduced this enzyme, probably involved in...

A 70-year-old African American female with a past medical history significant for chronic bilateral shoulder pain and reported sickle cell trait presented acute-onset thoracolumbar radiating to her left arm. Two days after admission, Hematology was consulted severely worsening microcytic anemia thrombocytopenia. Examination of the patient's peripheral blood smear from admission revealed no sickling, spherocytes, or schistocytes. Some targeting noted. Coombs test negative. The patient...

INTRODUCTION Giant condyloma acuminata (GCA), also knownbytheeponymBuschke-Lowenstein tumor, is a human papillomavirus (HPV) –associated verrucous carcinoma of the anogenital region. GCAs have welldifferentiated squamous histology and slow growth pattern characterized by local invasion. Despite frequent malignant transformation recurrence after therapy, they been reported to low metastatic potential. Here we report case patient with GCA treated systemic chemotherapy including epidermal...

e17555 Background: While health disparities and therapy outcomes within different racial ethnic populations has been studied, data on Hispanics is sparse. In an effort to provide care a benchmark for accrual efforts our predominately Hispanic population, the Cancer Therapy Research Center (CTRC), National Institute-designated in San Antonio, Texas, explored rates of patient participation prevention clinical trials. Methods: A search all phase II III cancer trials published 2012 calendar year...
