What causes secondary peritonitis?

The main cause of secondary pelvic peritonitis is pathogen infection. The pathogens of secondary pelvic peritonitis have two sources, exogenous and endogenous. The two pathogens can exist alone, but usually they are mixed infections. Exogenous chlamydia or gonorrhea Neisseria infection may cause fallopian tube damage, which is prone to secondary endogenous aerobic and anaerobic infection.

1. Exogenous pathogens

The main ones are pathogens that spread diseases, such as Chlamydia trachomatis and Neisseria gonorrhoeae. Others include mycoplasmas, including Mycoplasma hominis, Mycoplasma genitalium, and Ureaplasma urealyticum.

2. Endogenous pathogens

The microorganisms that originally reside in the vagina include aerobic and anaerobic bacteria. It may be an infection of only aerobic bacteria or only anaerobic bacteria, but mixed infection of aerobic and anaerobic bacteria is more common.

The main aerobic and facultative anaerobic bacteria are Staphylococcus aureus, hemolytic Streptococcus, and Escherichia coli; the anaerobic bacteria are Bacteroides fragilis, Peptococcus, and Peptostreptococcus. The characteristics of anaerobic infection are easy formation of pelvic abscesses and infectious thrombophlebitis, and the pus has a fecal odor and bubbles.
