BACKGROUND The contamination of processed or unprocessed drinking water by fecal coliform bacteria has been reported worldwide. Despite a high incidence of waterborne diseases, entero-hemorrhagic Escherichia coli (EHEC) is an underacknowledged pathogen of concern to public health in India. Although the presence of EHEC is recorded in surface water resources of India, drinking water sources are ...
Yersinia enterocolitica is a widespread Gram-negative bacterium that causes gastrointestinal disease and other clinical manifestations in humans. Potentially pathogenic Y. enterocolitica has been isolated in Brazil, from human, environmental, food, and animal sources. Herein we report a genome sequence of Y. enterocolitica subsp. palearctica strain YE 19, serotype O:3, biotype 4, sequence type ...
BACKGROUND Salmonella enterica serovar Dublin is a zoonotic infection that can be transmitted from cattle to humans through consumption of contaminated milk and milk products. Outbreaks of human infections by S. Dublin have been reported in several countries including high-income countries. A high proportion of S. Dublin cases in humans are associated with invasive disease and systemic illness....
Understanding virulence is vital for the development of novel therapeutics to target infections with community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA), which cause an ongoing epidemic in the United States and are on a global rise. However, what defines virulence particularly of global CA-MRSA lineages is poorly understood. Threatening a vast population, the predominant ...
This study highlights the prevalence of aminoglycoside-modifying enzyme genes and virulence determinants among clinical enterococci with high-level aminoglycoside resistance in Inner Mongolia, China. Screening for high-level aminoglycoside resistance against 117 enterococcal clinical isolates was performed using the agar-screening method. Out of the 117 enterococcal isolates, 46 were selected f...
Evolution of virulence in epidemic community-associated methicillin-resistant Staphylococcus aureus.
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has recently emerged worldwide. The United States, in particular, is experiencing a serious epidemic of CA-MRSA that is almost entirely caused by an extraordinarily infectious strain named USA300. However, the molecular determinants underlying the pathogenic success of CA-MRSA are mostly unknown. To gain insight into the...
BACKGROUND A new type of meticillin-resistant Staphylococcus aureus (MRSA), designated community-acquired MRSA, is becoming increasingly noticeable in the community, some strains of which cause fatal infections in otherwise healthy individuals. By contrast with hospital-acquired MRSA, community-acquired MRSA is more susceptible to non b-lactam antibiotics. We investigated the high virulence pot...
An intraspecies phylogenetic grouping of 168 human commensal Escherichia coli strains isolated from the stools of three geographically distinct human populations (France, Croatia, Mali) was generated by triplex PCR. The distributions of seven known extraintestinal virulence determinants (ibeA, pap, sfa/foc, afa, hly, cnf1, aer) were also determined by PCR. The data from the three populations we...
