In this study, we characterized the humoral responses in cattle of Sardinia. The animals were divided into three groups: 1) 28 cattle infected with Mycobacterium bovis; 2) 48 cattle from herds in which foci of infection was notified; 3) 50 cattle from herds that were TB-free. Levels of IgG antibody were measured against the following antigens of M. tuberculosis: Heparin-Binding-Haemagglutin (HB...

A recent examination of measles virus mRNA molecules has shown that the nucleocapsid and haemagglutin messengers are of the size expected from a consideration of their protein products. However, the mRNA for membrane protein is approximately 50% larger than the size required. The molecular weight of matrix protein has been determined by SDS-polyacrylamide gel electrophoresis, and this procedure...

Recently, human infections with the novel avian-origin influenza A H7N9 virus have been reported from various provinces in China. Human infections with avian influenza A viruses are rare and may cause a wide spectrum of clinical symptoms. This is the first time that human infection with a low pathogenic avian influenza A virus has been associated with a fatal outcome. Here, a phylogenetic and p...

urinary tract infections (utis) are significant health problem, with escherichia coli as the primary pathogen in proximally 80% of cases. the adhesion of e coli to the host cell can be influenced by cell surface hydrophobicity (csh) and is an important factor for the development of infections. this study was conducted to find the relation between csh and one of the adhesions (mannose resistant ...

Newcastle disease virus (NDV) is an economically important poultry pathogen with a worldwide distribution that may infect a wide range of domestic and wild avian species. The identification of different pathotypes of NDVs plays an important role in the diagnosis and development of vaccines to control and eradicate NDV infections. In our previous study, we showed that mono-specific antibodies ca...
