Classical pathway haemolytic complement (CPHC) of the dromedary was assayed under standardised conditions. A total of 14 indicator systems of red blood cells (RBC) and haemolysins were investigated. Highest CH50 titre was obtained with rabbit RBC sensitised with goat haemolysin. Among the factors investigated were: ionic strength, Mg2+, Ca2+, ethylenediaminetetraacetic acid (EDTA) concentration...

Nodulation and host-specific recognition of legumes such as peas and Vicia spp. are encoded by the nodulation (nod) genes of Rhizobium leguminosarum biovar viciae. One of these genes, nodO, has been shown to encode an exported protein that contains a multiple tandem repeat of a nine amino acid domain. This domain was found to be homologous to repeated sequences in a group of bacterial exported ...

BACKGROUND This study investigated the prevalence of Enterococcus faecalis, its putative virulence factors and antimicrobial susceptibility in individuals with and without dental diseases. A total of 159 oral rinse specimens were collected from patients (n = 109) suffering from dental diseases and healthy controls (n = 50). RESULTS E. faecalis was detected using only culture in 8/109 (7.3%) o...

Staphylococcus epidermidis strains are diverse in their pathogenicity; some are invasive and cause serious nosocomial infections, whereas others are non-pathogenic commensal organisms. To analyse the implications of different virulence factors in Staphylococcus epidermidis infections, the complete genome of Staphylococcus epidermidis strain ATCC 12228, a non-biofilm forming, non-infection assoc...

Bacterial virulence factors (VFs) influence the site and severity of urinary tract infections (UTI) and further leading to sepsis infection. Phenotypic characterisation of VFs specific to sepsis Escherichia coli strains has not been characterized in Indian population till date. In this data article, we have described important VFs of uropathogenic E. coli (UPEC) that is P fim, Type-1 fim, cell ...
