The discrimination between Staphylococcus epidermidis strains that contaminate and infect blood cultures is a daily challenge for clinical laboratories. The results of PCR detection of putative virulence genes were compared for contaminating strains, sepsis-related strains, catheter strains, and saprophytic strains. Multiplex PCR was used to explore the atlE gene, which is involved in initial a...

We tested the activity of the new fluoroquinolone sparfloxacin (CI-978; AT 4140) against 30 strains of Mycobacterium avium complex (MAC) isolated from patients with acquired immune deficiency syndrome. MICs of sparfloxacin (range, less than or equal to 0.06 to 4 micrograms/ml) were lower than MICs of ciprofloxacin for all 30 strains, and MBCs for acid-fast bacteria were lower for 28 of the 30 s...

The species belonging to the Acinetobacter genus are currently reported as opportunistic pathogens in hospitalized patients with underlying predispositions. However, except for the Acinetobacter calcoaceticus-Acinetobacter baumannii complex, the identification of other species is frequently unreliable, especially for Acinetobacter ursingii and Acinetobacter schindleri, newly described in 2001. ...

In the periods from July to November 1995 and 1996, fecal samples from Dutch cattle and sheep were collected at the main slaughterhouses of The Netherlands, located at different geographic sites. The samples were examined for the presence of verocytotoxin (VT)-producing Escherichia coli (VTEC) of serogroup 0157. E. coli O157 strains could be isolated from 57 (10.6%) of 540 adult cattle, 2 (0.5%...

This is a report of the complete genome sequences of plaque-selected isolates of each of the five virus strains included in a South African commercial trivalent bluetongue virus (BTV) attenuated live virus vaccine, a BTV-4 field strain isolated from Rustenburg, South Africa, in 2011, and a bluetongue reassortant (bluetongue virus 4 strain 4/O. aries-tc/ZAF/11/OBP-115) isolated from experimental...

seventy-five meconium samples were examined for the presence of ci. difficile: 3 strains were isola ted. additionally 45 labora tory animal faeces specimens were tested for the same purpose, a further 2 cases were isolated. these five suspicious strains were identified as ci. difficile acco rding to the tests mentioned in the previous paragraphs. the organisms . isolated here showed the same ch...

We present for the first time pseudoelasticity and shape memory results on Co–Ni–Al single crystals in tension. The experimental transformation strains approached 6% in tension in the [115] orientation. Despite the considerable volume change (0.0447), the transformation exhibits remarkable pseudoelasticity and shape memory recoverability in tension. A theoretical treatment is presented to expla...

Several unusual fatty acids characterized strains of Francisella tularensis. Long-chain (C20-C26) acids and the hydroxy acids 2-hydroxy-decanoate, 3-hydroxy-hexadecanoate, and 3-hydroxy-octadecanoate appeared to be of special diagnostic value.

Abstract Flavescence dorée is an economically important vector-borne disease of grapevine in Europe caused by phytoplasmas belonging to the 16SrV ribosomal group. Expression profiles 11 genes phytoplasma (FDp) were analysed over time following infection natural ( Vitis vinifera and leafhopper vector Scaphoideus titanus ) experimental Vicia faba Euscelidius variegatus hosts. Infected symptomatic...
