no. ISTN3X; 96% identical), comprising one of Tn3-like inverted repeats and putative coding regions for transposase, resolvase (also called repressor), and ampicillin resistance. The resistance gene encodes a TEM-1 type β-lactamase. (The sequence has been registered to DDBJ/GenBank/ EMBL with accession no. AB103092.) Conjugative transferability of p981123 between S. Enteritidis strains was exam...

Salmonella enterica serotype Heidelberg is the fifth-most-common serotype that causes human disease in the United States, and it appears to be more invasive than other nontyphoidal serotypes (3, 6). In March 2011, a multistate outbreak of Salmonella enterica serotype Heidelberg infections was investigated (2). Pulsed-field gel electrophoresis (PFGE) analysis of isolates from suspected cases and...

By September 2, it was revealed that seven other individuals who had traveled to Hawaii with the patie...

Sir, In Gram-negative bacteria, extended-spectrum b-lactamases (ESBLs) are widespread enzymes conferring resistance to most b-lactams, including third-generation cephalosporins but with the exception of carbapenems and cephamycins. In animals, the blaCTX-M-1 gene is one of the most frequently reported ESBL-encoding genes; in contrast, in humans the blaCTX-M-15 gene is highly prevalent. Plasmids...

Only a few agonists exhibit selectivity between the AMPA and the kainate subtypes of the glutamate receptor. The most commonly used kainate receptor preferring agonist, (S)-2-amino-3(5-tert-butyl-3-hydroxy-4-isoxazolyl)propionic acid [(S)-ATPA], is an (R,S)-2-amino-3-(5-methyl-3-hydroxy-4-isoxazolyl)propionic acid (AMPA) derivative in which the methyl group at the 5-position of the isoxazole ri...

In 2001, Salmonella Enteritidis phage type (PT) 30 was isolated from drag swabs of 17 61-ha almond orchards on three farms linked to an outbreak of salmonellosis associated with consumption of raw almonds. The objective of this study was to evaluate the long-term persistence of Salmonella Enteritidis PT 30 in one of the almond orchards associated with the outbreak. Swabs (gauze saturated with f...

The Chondrichthyes (cartilaginous fishes) are commonly accepted as being sister group to the other extant Gnathostomata (jawed vertebrates). To clarify gnathostome relationships and to aid in resolving and dating the major piscine divergences, we have sequenced the complete mtDNA of the starry skate and have included it in phylogenetic analysis along with three squalomorph chondrichthyans—the c...
