Stimulation of cardiac AMP-activated protein kinase (AMPK) has been demonstrated in both prohypertrophic and antihypertrophic settings, although the reasons for such discrepant results are not well understood. We determined how AMPK is regulated in response to phenylephrine-induced cardiomyocyte hypertrophy and assessed whether AMPK activity may be a factor underlying the antihypertrophic effec...

background and aims: inclusion body hepatitis (ibh) is one of the most important reemerging diseases in many countries with intensive poultry industries. in iran, the etiological agent of ibh (fowl adenovirus) has not been yet confirmed. the aim of this study was the molecular detection and identification of fowl adenovirus involving ibh in chicken flocks in iran. materials and methods: polymer...

aim : the purpose of this study was to characterize phenotypically and genotypically the serotypes of the e. coli o111 associated with diarrheal disease and assess the variation among serotypes in terms of specific virulence factors and hela cells adherence patterns. background : escherichia coli o111 serogroups are prevalent in endemic or sporadic cases of diarrhea, especially in developing ar...

We developed immunoglobulin M (IgM) antibody capture enzyme-linked immunosorbent assays (ELISAs) with four monovalent dengue virus antigens. We attempted to determine whether IgM responses in dengue virus infections are serotype specific or serotype cross-reactive. Serum samples from 14 confirmed dengue cases were examined. In these 14 cases, which consisted of 12 Japanese and 2 non-Japanese pa...

The National Rotavirus Reference Centre, together with collaborating laboratories Australia-wide, conducts a laboratory based rotavirus surveillance program. This report describes the serotypes of rotavirus strains responsible for the hospitalisation of children with acute gastroenteritis during the period 1 July 2006 to 30 June 2007. One thousand and two faecal samples from across Australia we...

Streptococcus pneumoniae serotype 19A remains a significant cause of invasive pneumococcal disease (IPD) in Ireland despite the successful introduction 13-valent conjugate vaccine (PCV13) 2010 which reduced overall incidence IPD children. Invasive isolates from Irish reference laboratory between 2007–08 and 2017–18 were analysed using whole genome sequencing (WGS) to investigate persistence thi...

Changes in serotype distribution have been described after the switch from 13-valent pneumococcal conjugate vaccine (PCV13) to 10-valent (PCV10) Belgium. To describe serotype’s invasive disease potential and detailed evolution of antimicrobial susceptibility isolates (carriage IPD) children up 30 months age over a period during (2015–2018). S. pneumoniae strains isolated nasopharynx healthy att...

Thirty-one strains of Yersinia enterocolitica were isolated from food and surface water. During the period of January 1975 to June 1977, 157 strains from 143 human cases were also isolated. Among the different serotypes from nonhuman sources, serotypes 6,30 and 4,32 were the most common. Serotype 4,32 was present only in food and not in water. Serotype 3 was isolated only from humans. Among the...
