PathWest Laboratory Medicine WA detected RRV IgM antibodies using an inhouse indirect immunofluorescence antibody (IFA) test, but no RRV antibodies were detected using an inhouse haemagglutination inhibition (HI) antibody test 10 days after blood donation. RRV IgM antibodies are detected by IFA testing within a few days of onset of illness and routinely persist for several weeks or, occasionall...

Neonatal hypoxic-ischemic (HI) brain injury is a devastating disease that often leads to death and detrimental neurological deficits. The present study was designed to evaluate the ability of metformin to provide neuroprotection in a model of neonatal hypoxic-ischemic brain injury and to study the associated molecular mechanisms behind these protective effects. Here, we found that metformin tre...

The aim of this work was to detect serum antibodies specific to influenza viruses in swine in Brazil. Serum samples of 355 pigs from 17 herds in Minas Gerais state were tested by hemagglutination inhibition (HI) for antibodies against H1N1 swine (SIV) and human influenza viruses, and H3N2 SIV. HI revealed that 158 animals (44·5%) and 11 herds (64·7%) were positive for H1N1 SIV, 36 animals (10·1...

Sera from various wild ruminants co-existing in the same habitats with cattle had haemagglutination-inhibition (HI) antibodies as high as those in the cattle. Sera from wildebeest (Connochaetes taurinus), kongoni (Alcelaphus cokei), Thomson’s gazelle (Gazella thomsonii), eland (Taurotragus oryx) and the African buffalo (Syncerus caffer) had titers ranging from 64 to 128. Zebra (Equus burchelli)...

The aim of this study was to investigate the prevalence of CIV H3N8 in dogs in Germany. Blood samples from 272 clinically healthy dogs and 35 dogs with acute respiratory signs were screened for antibodies against influenza virus by ELISA and haemagglutination inhibition (HI) assay; positive samples were further tested by fluorescent antibody test (FAT) and subtype-specific HI assay. Nasal and p...

Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent was a low-pathogenicity H9N2 avian influenza virus that caused frequent episodes of high mortality in broiler chicken farms in Iran and some other Asian countries. This study was designed to investigate the prevalence of AIV H9N2 subtype in commercial chicken flocks in Dezful, southern Iran...

Incorporating species-specific anti-immunoglobulin G (IgG) serum into the hemagglutination-inhibition (HI) test for influenza markedly increased sensitivity without loss of specificity. The effectiveness of anti-IgG serum for augmenting antibody titers may be influenced by the variable potency of commercial anti-IgG preparations. Maximal enhancement of HI titers was achieved when anti-IgG serum...

INTRODUCTION Haemagglutination-inhibition (HI) antibody titer is a correlate of protection against influenza; its persistence after infection or vaccination is important to determining susceptibility to subsequent infection. Few studies, however, have reported longitudinal data regarding the magnitude and duration of HI protection following natural seasonal influenza A infection. METHODS Usin...

 Endophytic bacteria have several advantages, including controlling plant pathogens and increasing growth. As a biological control, endophytic can suppress the development of pathogenic fungi. This study aimed to obtain consortium that inhibit growth C. oryzae. The used Completely Randomized Design (CRD) for studying ability using eight isolates: Bacillus sp HI, SJI, B. cereus P14, Se07,...
