We compared the potential phenotypic properties of coryneform bacteria associated with chronic prostatitis syndrome （CPS）, such as secretory inhibitor of lysozyme （SIL） and secretory inhibitor of platelet microbicidal protein （SIPMP）. A total of 110 clinical isolates of coryneform bacteria isolated from the seminal fluid of healthy men and men with CPS were tested. SIPMP production was tested by inhibiting platelet microbicidal protein （PMP） bioactivity against Bacillus subtilis, and was expressed as percentage of inhibition of PMP bactericidal activity. SIL production was tested by inhibiting lysozyme activity against Micrococcus lysodeikticus and was expressed in microgram per millilitre of inactivated lysozyme. A significantly higher proportion of CPS strains （58.7% vs. 19.2 %） was SIPMP-positive compared with non-CPS strains （P 〈 0.01）. Of the CPS strains tested, 77.8% were SIL-positive compared with 34% of the non- CPS isolates （P 〈 0.05）. These results suggest that the diagnosis of CPS should not rely solely on classical parameters, for example, the identification and counting of microorganisms, but the functional significance of these parameters must be estimated, possibly by the concentration of different bacterial substrains, detection of opportunistic microorganisms with pathogenic properties, such as pronounced resistance to the cationic antimicrobial peptides, and/or the ability to inhibit the antimicrobial host defence factors.

In this study,we determined the levels of cytokine secretory inhibitors and the microbiota biofilms of semen from healthy and infertile subjects.A total of 118 clinical bacterial isolates were isolated and *** secretory inhibitors were determined based on the difference in cytokine content between the control and experimental samples of cell-free supernatants of isolated *** formation was studied by determining the adhesion of microorganisms to the surface of a 96-well sterile plate and expressed as the optical density at 630 nm(Od_(630)).Cell-free supernatants of Staphylococcus contained higher levels of secretory inhibitor of cytokines in conditionally healthy than in infertile *** contrast,in infertile men,the ability to reduce cytokine levels was more characteristic of Enterococcus and *** Staphylococcus,Corynebacterium,and Enterococcus isolated from infertile subjects showed a greater ability to form biofilms than the same bacteria isolated from healthy *** research is needed on this topic,since it is necessary to determine the relationships between decreased secretory inhibitors of cytokines,production of biofilms by bacteria in semen,and *** is likely that the ability of microorganisms to change the concentration of cytokines and increase the level of biofilm formation in semen may be associated with minimal impairments of fertilizing ability,which are not detected using other methods.

Aim： To report the detection in vitro of secretory inhibitor of platelet microbicidal protein （SIPMP） phenotypes of urethral isolates along with a comparisonwith isolates from patients with or without chronic bacterial prostatitis （CBP）. Methods： Urethral isolates of Staphylococcus spp. （n = 64）, diphtheroids （n = 28）, micrococci （n = 15）, streptococci （n = 21）, Enterobacteriaceae （n = 9） and Enterococcusfaecalis （n = 19） from patients with or without CBP were tested. SIPMP production was tested by inhibition of platelet microbicidal protein （PMP） bioactivity against Bacillus subtilis and was expressed as percentage of inhibition of PMP bactericidal activity. Results： A significantly higher proportion of CBP-strains （57.78% vs. 16.67%） reduced PMP-induced killing of Bacillus subtilis than non- CBP strains did （P 〈 0.01）. SIPMP levels of staphylococci and Enterococcusfaecalis from the CBP group were significantly higher than those of the control group. Conclusion： These results suggest that SIPMP production is associated with the CBP source. data from the present study might have significant implications for the understanding of the pathogenesis of CBP. （Asian J Androl 2008 Mar; 10： 189-192）.
