What is the common pathogen associated with endometritis?

Endometritis is an infection of the endometrial lining of the uterus, often occurring after childbirth, miscarriage, or any invasive procedure involving the uterus. The most common pathogen associated with endometritis is Escherichia coli, a type of bacteria that is normally found in the intestines. E. coli can gain access to the endometrial cavity in certain clinical situations, such as following delivery or surgical interventions, leading to infection.

E. coli can act as an opportunistic pathogen when the normal barriers of the reproductive tract are compromised, which is why it is frequently implicated in cases of endometritis. Other organisms can also be involved, particularly in polymicrobial infections, but E. coli remains the predominant pathogen in many cases due to its prevalence and virulence factors that promote infection.

In contrast, Streptococcus pneumoniae is primarily associated with respiratory infections and does not typically cause endometritis. HIV, which is a virus, is related to immune system compromise rather than direct infection of the endometrium. Clostridium perfringens is associated with gas gangrene and certain types of food poisoning but is less commonly linked to endometritis compared to E. coli. Thus, the identification of E. coli as the
