The culture supernatants of the emerging Middle East respiratory syndrome coronavirus (MERS-CoV) were submitted to three temperatures over time and tested for infectivity by TCID50 method on Vero E6 cells. At 56°C, almost 25 minutes were necessary to reduce the initial titre by 4 log10 . Increasing temperature to 65°C had a strong negative effect on viral infectivity as virucidy dropped signifi...

In two patients with a persisting, high antistreptolysin titre the antistreptolysin activity in both cases resided exclusively in a monoclonal IgG component in the serum. This component had all the characteristics of a true antibody. A history in both patients of arthritis with or without angina suggested that the monoclonal antibodies were reactive in origin, although definite proof was lackin...

A trial of a modified reverse passive haemagglutination test for HBsAg using a 0.1% cell suspension instead of the recommended 1% showed an approximately eight-fold increase in detection sensitivity. The test can be performed within 30 minutes and lends itself to mass screening techniques. Confirmation tests can be done using the 0.1% method. In addition, the same serological plates and cells u...

Three hundred and twenty four serum samples, collected from different areas of Punjab, NWFP and Azad Kashmir, were screened for Toxo IgG and IgM antibody titres utilizing the Enzyme linked immunosorbent assay (ELISA). Of the total 149 (46%) samples were positive for IgG antibody. Seven (2.1%) showed titre greater than 130. Ninety sera (27.7%) were positive for IgM antibody, twenty six (8%) had ...

Sir, Cryptococcosis is an opportunistic infection caused by Cryptococcus neoformans and is usually seen in immunocompromised patients. Histopathologically, the skin lesions are divided into two types, i.e. cystic and granulomatous lesions (1, 2), each of which occurs exclusively depending on the conditions of individual hosts (3). For unknown reason the titre of cryptococcal antigen in patients...

Three patients with acute oropharyngeal palsy had high titre anti-GQ1b and anti-GT1a IgG antibodies. No patients had ophthalmoplegia or ptosis. In all patients limb ataxia or areflexia were present without notable limb weakness. These patients describe an oropharyngeal variant of Guillain-Barré syndrome in terms of anti-GQ1b antibody reactivity and show that high titre anti-GQ1b antibodies, ser...

During a meningococcal (group A) epidemic, 47 Nigerian children with acute meningococcaemia without meningitis were studied. Their mortality rate was 43% compared with 8% during the whole epidemic. Those presenting with coma and shock had a mortality of 93%, but without shock or coma mortality was only 6%. Coma or shock occurring alone carried an intermediate prognosis. The outcome correlated w...

A large proportion of high titre Coxsackie B5 complement-fixation tests was detected among sera giving false positive Wassermann reactions during 1969. Echo virus type 9 proved to be the prevailing enterovirus and is one of those which induces the formation of antibody to Coxsackie B5. One case of Echo virus type 9 meningitis is presented which produced a false positive Wassermann reaction and ...

An adaptation of an enzyme immunoassay technique was developed to screen donor plasma for high titres of antibodies to cytomegalovirus (CMV). The technique uses microtitre plates treated with glutaraldehyde and coated with CMV antigen and an anti-IgG alkaline phosphatase conjugate to detect the captured antibody. Using an anti-CMV standard with a 1/64 titre by complement fixation, 34 (6.8%) of ...
