**Abstract**

Sexually transmitted diseases are among the most contagious infections caused by a variety of microorganisms such as viruses, bacteria, fungi, and protozoa. Worldwide, the incidence of bacterial sexually transmitted infections has shown a gradual increase in recent years. Common bacterial sexually transmitted diseases are Chlamydia, gonorrhea, and syphilis. Any person with signs or symptoms suggestive of bacterial sexually transmitted infections should receive a test, even if he or she does not have symptoms or know of a sex partner. Bacterial sexually transmitted diseases can be cured with the right treatment. It is important to take all medications based on the prescription to cure the sexually transmitted infection. Chlamydia is the most common bacterial sexually transmitted infection globally. Gonorrhea strains that are multi-drug resistant have been widely dispersed worldwide. Neisseria gonorrhoeae has a high level of antibiotic resistance, leading to untreatable infections that could one day pose a serious threat to public health and present the greatest obstacles to the prevention and management of sexually transmitted illnesses. Because there is no documented penicillin resistance, penicillin remains the first-line therapy for syphilis.
