The present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of STEC from healthy goats of West Bengal, India. From the 125 faecal samples collected from healthy goats, 245 isolates were identified as Escherichia coli. The E. coli harbouring any gene for Shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...

This study was conducted to determine the prevalence and characteristics of pathogenic Escherichia (E.) coli strains from diarrheic calves in Vietnam. A total of 345 E. coli isolates obtained from 322 diarrheic calves were subjected to PCR and multiplex PCR for detection of the f5, f41, f17, eae, sta, lt, stx1, and stx2 genes. Of the 345 isolates, 108 (31.3%) carried at least one fimbrial gene....

The present experiment was performed according to a 4 3 4 Latin square design with diets composed of (on dry matter (DM) basis) the following ratios of grass hay to whole oats: 100:0 (O0), 80:20 (O20), 60:40 (O40) and 40:60 (O60). Four mature Standardbred geldings weighing 493 (S.D. 34) kg were used. The digestibility of DM, organic matter and energy (dE) increased in a curvilinear pattern with...

This paper conducts an in-depth analysis of the impacts of the global financial crisis on the People’s Republic of China’s (PRC’s) small and medium enterprises (SMEs). It also provides relevant policy suggestions at the end. First, this paper reviews the impacts of the 1997 Asian financial crisis on the PRC’s SMEs, evaluating the policy measures for coping with the crisis at that time and summa...

To examine the genetic background of avian pathogenic Escherichia coli (APEC) that affects virulence of this microorganism, we characterized the virulence genes of 101 APEC strains isolated from infected chickens between 1985 ˜ 2005. Serotypes were determined with available anti-sera and median lethal doses were determined in subcutaneously inoculated chicks. The virulence genes we tested inclu...

The majority of African countries implemented import liberalisation in the 1990s. This paper explores factors that may explain the pattern of protection and of tariff reform. We consider political economy explanations, motivated specifically by the Grossman and Helpman (1994) model of protection in response to industry lobbies, and the possibility that reforms are technocratic. Using industry-l...

Crystals of an ion-channel-forming peptaibol peptide in a partial membrane environment have been obtained by cocrystallizing antiamoebin with n-octanol. The antiamoebin molecule has a bent helical conformation very similar to that established for Leu-zervamicin, despite a significantly different sequence for residues 1-8. The bent helices assemble to form a polar channel in the shape of an hour...

In the context of the superconformal N = 4 SYM theory the Konishi anomaly can be viewed as the descendant K10 of the Konishi multiplet in the 10 of SU(4), carrying the anomalous dimension of the multiplet. Another descendant O10 with the same quantum numbers, but this time without anomalous dimension, is obtained from the protected half-BPS operator O20′ (the stress-tensor multiplet). Both K10 ...

over half of all reported traumatic brain injuries are the result of a motor vehicle accident. other then the direct head impact itself, the sheer forces of the accident can cause the brain also to collide against the internal bone of the skull. in fact, when a moving head comes to a quick stop, the brain continues in its movement, striking the interior of the skull. this can cause bruising of ...

injuries suffered in vehicle traffic crashes are the leading cause of death among children in many countries. prevention of injuries of children in raod accidents is still a challenge. the present lecture discuss the commonly injuried body regions in children involved in motor and non-motor vehicle traffic crashes. head, ribs and lung are commonly injured body regions among children under 8 yea...
