Gram-positive bacilli are rod-shaped bacteria that stain positively for grams and may cause pelvic inflammatory disease, bacterial vaginosis, and other gynecological conditions. 1. Pelvic inflammatory disease: patients will have symptoms such as abdominal pain, fever, increased vaginal discharge, abnormal vaginal bleeding, etc. Antibiotic treatments need to be taken accordingly for different pathogenic bacteria. 2. Bacterial vaginosis: this disease is the result of a variety of pathogenic bacteria, mostly Gardnerella, digestive streptococcus, etc. It can be induced by frequent sexual intercourse, multiple sexual partners, bad lifestyle habits, decreased resistance and other factors. Some patients are asymptomatic, and those with symptoms will have increased grayish-white vaginal discharge with a fishy odor. In addition to gynecological diseases, infection with gram-positive bacilli can also cause erysipelas, otitis media, pneumonia, endocarditis, gastroenteritis, lymphadenitis and other diseases. When infected with Gram-positive bacilli, treatment should be targeted according to the specific disease under the guidance of a doctor.
