Of 35 women with acute salpingitis on laparoscopy, 86% had chlamydial antibodies at a titre of 1/16 or higher and 49% at a titre of 1/512 or higher. Geometric mean titres of chlamydial antibodies correlated significantly with a laparoscopic observation of chronic salpingitis (p less than 0.001), with a history of infertility (p less than 0.05), and with severe inflammation (p less than 0.10), b...
Antibody titres were measured in patients with clinical syphilis, and the effect of treatment on the results of the Treponema pallidum immune adherence (TPIA) test is reported. In the Treponema pallidum haemagglutination (TPHA) test little change in antibody titre occurred after treatment while in the fluorescent treponemal antibody-absorbed (FTA-ABS) test only a slight decrease occurred. The d...
Between January 1981 and December 1989, 258 patients with positive syphilis serology underwent lumbar puncture. Nine patients had long-standing neurosyphilis and had lumbar punctures performed during the course of their follow-up. Of the remaining 249 only 12 demonstrated the presence of TPHA in the CSF. The serum TPHA titre for eight of these 12 patients, and seven of the nine (two having no t...
The diagnostic value of the Widal test was assessed in an endemic area. The test was done on 300 normal individuals, 297 non-typhoidal fevers and 275 bacteriologically proven cases of typhoid. Of 300 normal individuals, 2% had an H agglutinin titre of 1/160 and 5% had an O agglutinin titre of 1/160. On the basis of these criteria a significant H and/or O agglutinin titre of 1/320 or more was ob...
The sensitivity of HD antibody in cancer diagnosis/prognosis could be improved by detection of Immune Complex (IC) dissociated antibody. Combined evaluation of native HD and Immune Complex (IC) dissociated antibody was carried out. Presence and titre of these antibodies in cancer patients was investigated in serum samples obtained from 420 patients with various types of tumors. Results were com...
BACKGROUND Succinic acid is well established as bio-based platform chemical with production quantities expecting to increase exponentially within the next decade. Actinobacillus succinogenes is by far the most studied wild organism for producing succinic acid and is known for high yield and titre during production on various sugars in batch culture. At low shear conditions continuous fermentati...
OBJECTIVES To investigate the effect of Chlamydia pneumoniae infection on future development of ischaemic heart disease and mortality. DESIGN Prospective longitudinal study. SETTING Caerphilly, South Wales. SUBJECTS Plasma specimens were collected during 1979-83 from 1773 men aged 45-59 years. These were tested for IgG and IgA antibodies to C pneumoniae (TW183) by microimmunofluorescence....
Pupal development is elicited early in the last larval instar of the tobacco hornworm, Manduca sexta (Johannson), by a precise temporal and quantitative increase in the haemolymph titre of 20-hydroxyecdysone. This increase in the titre is referred to as the pupal commitment peak, and it occurs once the titre of juvenile hormone (JH) has dropped. If the haemolymph titre of JH remains elevated at...
