Sera from fifty patients with gonorrhoea, thirty with non-specific urethritis, and eighty blood donors were treated with mercaptoethanol (ME) and examined by the indirect haemagglutination test for antibodies against endotoxin from gonococci. Erythrocytes sensitized with determinant a of endotoxin from Strains 8551, V, and VII, or determinant b from Strain V were used. The percentage of sera ac...

Avian Infectious bronchitis virus belongs to the family Coronaviridae. It is an enveloped virus with large positive stranded RNA genome. In the present study RNA was isolated from viral suspension and transcribed into cDNA. Poultry postmortem cases showing lesions of visceral gout were collected and infectious bronchitis virus were isolated. About 1.2 kb Nucleocapsid gene of virus was amplified...

Our understanding of the antigenic evolution of the human influenza virus is chiefly derived from experiments in which serum from influenza infected ferrets is tested against panels of virus isolates in the haemagglutination inhibition (HI) assay. The interpretation of these results has been much aided by the development of antigenic mapping techniques, which suppose that the antigenic distance...

THe immune response, as measured by the haemagglutination-inhibition test, to the simultaneous administration of live Hitchner B1 and 2 commercially available, inactivated, oil-based, emulsified, Newcastle disease vaccines at day-old is described. The response was monitored from day-old to 18 weeks, when the birds were challenged with a standardized virulent virus. It was found that the haemagg...

Possible involvementofendogenousopioids inhumoral immune responseshas been explored in the experimental animals. Opioid agonists likemorphine and leu-enkephalin significantly enhanced antigen-inducedhistamine release from the peritoneal mast cells of sensitised rats invitro; this was effectively antagonised by naloxone. Naloxone itselfinhibited antigen-induced histamine rele...

Twenty-nine synovial fluids from patients with rheumatoid arthritis (RA) and 10 synovial fluids from patients with other joint diseases were investigated with regard to the presence of antibodies to denatured human collagen and of collagen-anticollagen immune complexes. 12 of the 29 RA synovial fluids showed anticollagen titres from 1:16 to 1:512 in passive haemagglutination. Only one patient i...

Prevalence of antibodies against some important disease agents in sera from racing camels in Abu Dhabi (United Arab Emirates) is reported. Antibodies against Brucella abortus were detected in 1.5% of racing camels, but only 0.76% had titres sufficient for the animals to be considered infected. The complement fixation test revealed antibodies against Coxiella burnetii (causative agent of Q fever...

Present study was done to evaluate the effect of Ocimum sanctum seed oil (OSSO) on the immunotoxicity and oxidative activity of lindane in rats. Rats were divided into four groups (n = 8) and were treated with lindane (10 mg/kg, po) and/or OSSO (1 mg/kg, po) during the study period. Humoral immunity was assessed by measuring haemagglutination titre to sheep red blood cells (SRBC) and delayed ty...

showed a haemoglobin concentration of 124 g 1; white cell count 2-4x 109/1 (76°,' neutrophils, 20",, lymphocytes, 4",, monocvtes); platelet count 200 x 109 1; sedimentation rate 44 mm in first hour; normal urea and electrolytes and liver function values; antinuclear factor titre positive at 1/1280; rheumatoid arthritis haemagglutination titre positive at 1 80; and double stranded deoxyribonucle...

INTRODUCTION Pandemic influenza A H1N1 infections occurred worldwide from 2009. Children were particularly vulnerable. Novel vaccines were used during the pandemic. OBJECTIVE To assess the persistence of antibody to H1N1 influenza 1 year after children aged 6 months to 12 years had been immunised with two doses of either a non-adjuvanted whole-virion H1N1 influenza vaccine or an AS03B-adjuvan...
