venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis serovars L1, L2, or L3 and their variants.
In addition to donovanosis, there are other sexually transmitted infections that are mostly found in the tropics that cause similar symptoms.13 These are chancroid and lymphogranuloma
No cases of chancroid, nongonococcal urethritis and granuloma inguinale, or lymphogranuloma
venereum were observed in the present study.
* The differential diagnosis for unilateral inguinal lymphadenopathy with associated constitutional symptoms was broad, in this case, and included pelvic inflammatory disease, bubonic plague, iliopsoas abscess, lymphogranuloma
venereum, bartonellosis, infectious mononucleosis, and tick-borne diseases, such as ehrlichiosis, tularemia, Lyme disease, Rocky Mountain spotted fever, and Colorado tick fever.
He discusses general information on STDs in relation to sex, risks, definitions, and other topics; types, including chlamydia, gonorrhea, trichomoniasis, genital herpes, genital warts, syphilis, hepatitis B, hepatitis C, HIV, bacterial vaginosis, water warts, chancroid, HPV, pelvic inflammatory disease, mucopurulent cervicitis, lymphogranuloma
venereum, yeast infection, crabs, and scabies; signs, symptoms, and diagnosis; and treatment and prevention.
"Others" included those with gonorrhoea, lymphogranuloma
venereum and molluscum.
trachomatis have different serovars: A, B, Ba, and C lead to trachoma, D to K lead to genital tract Chlamydia infection, and L1-L3 lead to lymphogranuloma
(1,8) Some of the other less-common causes noted are lymphogranuloma
venereum (LGV) caused by specific serotypes of Chlamydia trachomatis, still determined to be rare, but with sporadic outbreaks increasingly reported, (1,9) and granuloma inguinale (donovanosis), another rarely encountered infection in the U.S.
 and bacterial sexually transmitted infections (STIs) such as lymphogranuloma
venereum and chancroid were the more common with 30.30% and 19.50%, respectively, in the study done by Sayal et al.
The differential diagnosis of ulceroglandular and glandular tularemia includes diseases such as cat scratch disease, malignancy, mycobacterial infections, syphilis, lymphogranuloma
venereum, chancroid, streptococcal or staphylococcal lymphadenitis, fungal infection, toxoplasmosis, mouse bite fever, herpes simplex infection, and anthrax (7).
And it has been reported that Chlamydia lymphogranuloma
venereum can strongly induce autophagy in the middle of the chlamydial developmental cycle (24 h after infection), suggesting that autophagy is activated primarily in response to the metabolic stress consequent to chlamydial replication .
