Shigella and pathogenic Escherichia coli are major causes of human infectious diseases and are responsible for millions of cases of diarrhea worldwide every year. A convenient and rapid method to identify highly pathogenic serotypes of Shigella and E. coli is needed for large-scale epidemiologic study, timely clinical diagnosis, and reliable quarantine of the pathogens. In this study, a DNA mic...
This study assesses dynamics of openness and finance in Africa by integrating financial development dynamics of depth, activity and size in the assessment of how financial, trade, institutional, political and other openness policies (of second generation structural and institutional reforms) have affected financial development. The empirical evidence is based on Generalized Method of Moments wi...
The role of resident cells during the lipopolysaccharide (LPS)-induced neutrophil recruitment into rat air pouches was investigated. In this model, LPS (Escherichia coli, O55: B5 strain; 2-2000 ng) induced a dose- and time-dependent neutrophil recruitment accompanied by the generation of a tumour necrosis factor-alpha (TNFalpha)-like activity. Dexamethasone (0.05-5 mug) and cycloheximide (6 ng)...
BACKGROUND/AIM A "new" pathogenic agent, verocytotoxin--producing Escherichia coli (VTEC) emerged in the last 20 years, causing an increased number of sporadic cases, as well as of outbreaks of diarrhoeal diseases. Humans and animals can be infected with VTEC, but their epidemiological importance as a reservoir of this agent is not quite clear, especially in the Balkan region. Therefore, the ai...
Flagellar (H) antigens are mostly encoded by genes at the fliC locus in E. coli. We have sequenced 11 H7 fliC genes from Escherichia coli strains that belong to seven O serotypes. These sequences, together with those of nine other H7 fliC genes (from strains of three different O serotypes) sequenced recently (S. D. Reid, R. K. Selander, and T. S. Whittam, J. Bacteriol. 181:153-160, 1999), inclu...
Country-level longitudinal data at three-year intervals over 1990–2004 are used to analyze the factors affecting emigration of physicians from Sub-Saharan countries and the effects of this medical brain drain on life expectancy and number of deaths due to AIDS. Data are compiled on emigrating African physicians from 16 receiving Organisation for Economic Co-operation and Development (OECD) coun...
This paper investigates whether there is gender bias in the duration that children are breastfed in Africa. Given evidence that breastfeeding is negatively related to future fertility, we further investigate whether any part of the gender bias is due to son preference in fertility choice. We use identical methodology to Jayachandran and Kuziemko (2010), and compare our results on Africa to thei...
A total of 90 random samples of ready to-eat-pastry foods of meat pie, meat pizza and pasta pashamil. 30 samples of each were collected from different fast foods services at Kalyobia governorate to be examined bacteriologically for detection of pathogenic Escherichia coli microorganisms. The obtained results indicate that incidence of E.coli isolated from examined samples of pastry foods were 2...
Acute toxic interactions of intravenously administered benzyl alcohol and Escherichia coli O55:B5 (Boivin preparation) endotoxin were examined in rodents. Lethality studies in male CD-1 mice demonstrated that these agents were more toxic when administered in combination than when either was administered alone. Prophylactic treatment with diazepam (5 mg/kg intraperitoneally) protected against le...
The first documented British outbreak of Shiga toxin-producing Escherichia coli (STEC) O55:H7 began in the county of Dorset, England, in July 2014. Since then, there have been a total of 31 cases of which 13 presented with haemolytic uraemic syndrome (HUS). The outbreak strain had Shiga toxin (Stx) subtype 2a associated with an elevated risk of HUS. This strain had not previously been isolated ...
