Taylor-Robinson, David (National Institute of Allergy and Infectious Diseases, Bethesda, Md.), Otakar Sobeslavsky, and Robert M. Chanock. Relationship of Mycoplasma pneumoniae to other human Mycoplasma species studied by gel diffusion. J. Bacteriol. 90:1432-1437. 1965.-Conditions are presented for the production of four lines of precipitate between Mycoplasma pneumoniae antigen and homologous hyperimmune rabbit serum in double diffusion in agar. The specificity of the reaction was shown by the fact that M. pneumoniae antigen did not react with antisera to the other human mycoplasma species, nor did M. pneumoniae antiserum produce lines with antigens prepared from the other human mycoplasmas. In addition, there was no reduction in the number or intensity of precipitation lines after absorption of M. pneumoniae antiserum with heterotypic mycoplasma antigens, or after absorption of heterotypic mycoplasma antisera with M. pneumoniae antigen. These findings indicate that, of the human mycoplasma species so far studied, M. pneumoniae is antigenically the most distinct. 相似文献

Abstract A comparative study of the protein and lipopolysaccharide (LPS) profiles of 8 strains of Haemophilus ducreyi revealed that protein patterns remained unaffected by changes in medium composition, atmospheric conditions and temperature. In contrast, the LPS patterns exhibited marked variations under the different cultural conditions. 相似文献

Background
People with Cystic Fibrosis (CF) in the UK and elsewhere are increasingly surviving into adulthood, yet there is little research on the employment consequences of having CF. We investigated, for the first time in a UK-wide cohort, longitudinal employment status, and its association with deprivation, disease severity, and time in hospital.Methods
We did a longitudinal registry study of adults with CF in the UK aged 20 to 40 (3458 people with 15,572 observations between 1996 and 2010), using mixed effects models.Results
Around 50% of adults with CF were in employment. Male sex, higher lung function and body mass index, and less time in hospital were associated with improved employment chances. All other things being equal, being in the most deprived quintile was associated with a reduction of employment prevalence of 17.6 percentage points compared to the prevalence in the least deprived quintile. Having poor lung function was associated with a reduced employment prevalence of 7.2 percentage points compared to the prevalence for people with relatively good lung function. Acting synergistically, deprivation modifies the effect of lung function on employment chances – poor lung function in the least deprived group was associated with a 3 percentage point reduction in employment chances, while poor lung function in the most deprived quintile was associated with a 7.7 point reduction in employment chances.Conclusions
Greater deprivation, disease severity, and time in hospital are all associated with employment chances in adults with CF. Furthermore, our analysis suggests that deprivation amplifies the harmful association of disease severity on employment. Future studies should focus on understanding and mitigating the barriers to employment faced by people with CF. 相似文献7.
The biocontrol properties of Trichoderma species are well documented, but their effectiveness in antagonism of the problematic Sclerotium cepivorum, the causal agent of white rot in Allium species, appears limited with reports of significant control only relating to deliberately-mutated strains of Trichoderma. Our previous studies have indicated the possibility of using selected naturally-occurring strains of the antagonist in the suppression of other diseases; now in vitro and controlled environment in vivo studies have indicated that a degree of control of Onion White Rot is possible, and that the selected antagonist strains can be used in integrated treatments with Iprodione to good effect. The possible value of such treatments is considered in light of other approaches to the suppression of this continuing problem. 相似文献
