Haemophilus ducreyi

CausesChancroid

Haemophilus ducreyi bacteria causes a sexually transmitted infection (STI) called chancroid.
While this infection is highly contagious, it is curable.

Read on to learn about everything from chancroid symptoms to testing options.

Haemophilus ducreyi information

Clarity begins with testing.

At-home testing with secure, clinician-reviewed results.

What is Haemophilus ducreyi?

Haemophilus ducreyi bacteria can spread through unprotected sexual contact. It can also spread through non-sexual touching of an infected sore.

This bacteria is associated with chancroid, a sexually transmitted infection that can cause genital sores. When chancroid is symptomatic, symptoms are usually noticeable, especially because sores can be painful. People with this diagnosis also experience swelling in the groin's lymph nodes. This type of swelling happens in less than 50% of cases, according to the CDC.

Untreated chancroid causes more than just painful symptoms. It can also increase the risk of transmitting and acquiring HIV. As a result, it's important to get an accurate chancroid diagnosis.

How is chancroid transmitted?

Chancroid spreads through both sexual and non-sexual contact. In terms of sexual contact, this infection spreads through:

  • Vaginal intercourse
  • Oral sex
  • Anal sex

This infection can also spread through any other type of contact with an infected sore.

Safe sex is the best way to prevent the spread of this infection. This involves:

  • Using latex condoms during vaginal and anal sex
  • Relying on dental dams during oral sex

Limiting sexual partners and routine chancroid testing can also help with prevention.

What symptoms can chancroid cause?

A chancroid causes two main symptoms. Both affect the genital areas and include:

  • Open and draining genital sores that cause pain
  • Swollen and painful lymph nodes in the groin (inguinal lymphadenitis)

According to the Minnesota Department of Health, these symptoms can start within 4 to 10 days of exposure.

What are the complications when untreated?

Developing painful sores and lymph node swelling aren't the only risks of chancroid. Other risks of this infection include:

  • Greater risk of transmitting or acquiring HIV through sex.
  • Destruction of the foreskin tissue on the penis.

Genital sores can also become more easily infected with other types of germs.

When should I get tested for chancroid?

You might want to order a chancroid test if you have:

  • Symptoms of this STI (genital sores and/or swollen lymph nodes in the groin)
  • Had sex with someone who has this infection.

What are my testing options?

A chancroid diagnostic test is the best way to diagnose this infection.

Two main testing methods are available, including:

  • An in-clinic chancroid STD test
  • An at-home collection chancroid test, like the one from AllrangeKit

Some forms of testing use a urine sample, while others test a swab from a genital sore.
