Differential Attachment by Piliated and Nonpiliated Neisseria gonorrhoeae to Human Sperm

摘要: Piliated type 1 Neisseria gonorrhoeae attached to 50% of human sperm after incubation mixtures in vitro for 15 min at 35 C. In contrast, nonpiliated 4 N. only 23% sperm. Similar results were obtained with three different strains gonorrhoeae. Treatment heat or formaldehyde kill bacteria did not affect the amount attachment by piliated types. Escherichia coli and subflava, other species bacteria, about 40% sperm, meningitidis catarrhalis a comparable number as Prior purified antibody prepared against gonococcal pili reduced percentage same level that gonococci. treatment organisms Images
