Human campylobacteriosis, an infection caused by the bacterium Campylobacter, is a major issue in the United States food system, especially for poultry products. According to the Center for Disease Control, campylobacterosis is estimated to affect over 2.4 million people annually. Campylobacter jejuni and Campylobacter coli are 2 species responsible for the majority of campylobacterosis infecti...
Panton-Valentine leucocidin-positive methicillin-resistant Staphylococcus aureus (MRSA) strains with identical resistance patterns were cultured from recurrent infections of a 51-year-old patient, her healthy husband, son, and dog, and pulsed-field gel electrophoresis showed that all MRSA strains were indistinguishable.
Approximately 39% of methicillin-resistant Staphylococcus aureus (MRSA) sequence type 239 (ST239)-like bloodstream isolates from Liverpool Hospital (obtained between 1997 and 2008) carry an arginine catabolic mobile element (ACME). Whole-genome sequencing revealed that an ACME II variant is located between orfX and SCCmec III, and based on pulsed-field gel electrophoresis patterns and temporal ...
results the results showed that nl1-gc/ls2 primer set could yield species-specific amplicons, which were well distinguished and allowed better species discrimination than that generated by the its3-gc/its4 primer set, in both dgge and ttge profiles. all five candida species were discriminated by dgge and ttge using the nl1-gc/ls2 primer set. conclusions comparison of dgge and ttge profiles obta...
OBJECTIVE Knowledge of Bordetella pertussis circulating in Latin America is limited. Therefore, the goal of this study was to use pulsed-field gel electrophoresis and serotyping to characterize B. pertussis strains isolated in the city of São Paulo, Brazil. METHODS This study, conducted between 2006 and 2008, analyzed 652 nasopharyngeal swabs from suspected pertussis cases and contacts, colle...
Chloroplast DNA conformation was analyzed by pulse-field gel electrophoresis. We found that spinach leaf chloroplast DNA molecules exist in at least four distinct forms with the apparent molecular weights of monomer, dimer, trimer, and tetramer. Two-dimensional gel analysis of DNA after UV nicking and in the presence of ethidium bromide indicates that they are not isomers that differ in superhe...
An outbreak of Streptococcus suis serotype 2 emerged in the summer of 2005 in Sichuan Province, and sporadic infections occurred in 4 additional provinces of China. In total, 99 S. suis strains were isolated and analyzed in this study: 88 isolates from human patients and 11 from diseased pigs. We defined 98 of 99 isolates as pulse type I by using pulsed-field gel electrophoresis analysis of Sma...
