The study was conducted at 75 collecting loci in 15 districts of 11 provinces in Thailand during 1999-2004. A total of 12,079 live mollusks were collected, 11,874 were snails and 205 were clams. The snails were comprised of 39 species and classified into 9 families: Ampullariidae, Bithyniidae, Buccinidae, Potamiopsidae, Stenothyridae, Thiaridae, Viviparidae, Planorbidae and Lymnaeidae. The clam...

22 A linezolid resistant, vancomycin susceptible E. faecium strain was isolated from three 23 patients who had not received linezolid. The first patient was hospitalised in the same 24 hospitals and wards as the two following patients. The E. faecium isolates were resistant to 25 linezolid (MIC 8-32 mg/L), ampicillin and high levels of gentamicin. Resistance to linezolid 26 was associated with ...

Acinetobacter baumannii is a Gram-negative coccobacillus found primarily in hospital settings that has recently emerged as a source of hospital-acquired infections. A. baumannii expresses a variety of virulence factors, including type IV pili, bacterial extracellular appendages often essential for attachment to host cells. Here, we report the high resolution structures of the major pilin subuni...

We prove quantitative versions of Borel and Harish-Chandra's theorems on reduction theory for arithmetic groups. Firstly, we obtain polynomial bounds the lengths reduced integral vectors in any rational representation a reductive group. Secondly, construction fundamental sets subgroups groups, as latter vary real conjugacy class fixed Our results allow us to apply Pila--Zannier strategy Zilber-...

Let (K; +, ·,′ , 0, 1) be a differentially closed field. In this paper we explore the connection between Ax-Schanuel type theorems (predimension inequalities) for a differential equation E(x, y) and the geometry of the set U := {y : E(t, y)∧ y′ 6= 0} where t is an element with t′ = 1. We show that certain types of predimension inequalities imply strong minimality and geometric triviality of U ....

Consider a set S ⊂ Z. Suppose that, for many primes p, the distribution of S in congruence classes mod p is far from uniform. How sparse is S forced to be thereby? A clear dichotomy appears: it seems that S must either be very small or possess much algebraic structure. We show that, if S ⊂ Z ∩ [0, N ] occupies few congruence classes mod p for many p, then either S has fewer than N elements or m...

Bacteriophage Mx9 is a temperate phage that infects Myxococcus xanthus. It lysogenizes the bacteria by integrating into the bacterial chromosome by site-specific recombination at one of two sites, attB1 or attB2. Integration at attB1 results in deletion of DNA between the two attB sites. The attB2 site lies within the 5' region of the M. xanthus tRNA(Gly) gene. Mx9 integration requires a single...
