Granuloma Inguinale (Donovanosis) testing

Granuloma inguinale — also called donovanosis — is a rare bacterial sexually transmitted infection caused by <em>Klebsiella granulomatis</em>. It produces painless, slowly enlarging, beefy-red genital ulcers that bleed easily and can be mistaken for other conditions. Although it is very uncommon in the United States, it is curable with the right antibiotics, and accurate diagnosis usually relies on examining a sample of the ulcer tissue. If you have an unexplained, persistent genital sore, testing and evaluation are available.

Understanding granuloma inguinale (donovanosis)

What is granuloma inguinale (donovanosis)?

Granuloma inguinale, more commonly known as donovanosis, is a rare bacterial sexually transmitted infection caused by Klebsiella granulomatis. It is very uncommon in the United States, where most clinicians may never see a case. Globally, it is concentrated in a small number of tropical and subtropical regions, and U.S. cases are typically linked to travel or contact within those areas.

The infection is notable for its distinctive ulcers: painless, slowly growing, beefy-red lesions that bleed easily on contact. These sores usually appear on the genitals or perineum. Unlike some other ulcer-causing STIs, donovanosis characteristically does not produce the swollen, tender lymph nodes (buboes) that conditions such as lymphogranuloma venereum or chancroid often cause.

Because donovanosis is so rare in most settings, it is frequently not the first diagnosis considered when a genital ulcer appears. This makes a careful clinical evaluation important — the characteristic appearance of the ulcer, combined with examination of a sample of the lesion tissue, is how the diagnosis is confirmed.

Donovanosis is curable, but treatment requires patience. Antibiotics must be taken for an extended period — at least three weeks and until the lesions have fully healed. Even after apparently effective treatment, the infection can relapse months later, so follow-up matters.

Anyone with a persistent or unexplained genital sore should seek evaluation. Genital ulcers have many possible causes, and accurate identification guides the right treatment and helps prevent transmission to partners.

Screening guidance

Who should get tested for granuloma inguinale (donovanosis)?

Because granuloma inguinale (donovanosis) is usually silent, the CDC and U.S. Preventive Services Task Force recommend routine screening for the groups most likely to have it — not just people with symptoms.

  1. 1

    People with an unexplained genital ulcer

    Anyone with a painless, slowly growing, beefy-red sore that bleeds easily on the genitals or perineum should be evaluated, since these are the hallmark features of donovanosis.

  2. 2

    Travelers to endemic regions

    People who have had sexual contact in tropical or subtropical areas where donovanosis is more common should mention this history to their clinician if a genital ulcer develops.

  3. 3

    Sexual partners of diagnosed individuals

    Partners of someone diagnosed with granuloma inguinale should be evaluated, especially if they have had recent contact.

  4. 4

    Anyone with persistent ulcers not responding to other treatment

    If a genital ulcer fails to heal or was initially attributed to another cause, re-evaluation — including tissue examination — can help identify donovanosis.

Symptoms

What are the symptoms of granuloma inguinale (donovanosis)?

Donovanosis is defined by its visible ulcers rather than by silent infection. The lesions themselves are painless, which can delay recognition because the affected person may not feel discomfort prompting them to seek care. Lesions grow slowly over time rather than appearing suddenly. That's exactly why testing matters — you can have it, pass it on, and never feel a thing.

Hallmark ulcer features

  • Painless sores
  • Slowly growing, progressively enlarging lesions
  • Beefy-red appearance
  • Bleed easily when touched
  • Typically located on the genitals or perineum

What is usually absent

  • Swollen lymph nodes (buboes) — typically not present, unlike some other ulcer-causing STIs
  • Pain at the ulcer site
  • Sudden onset of multiple lesions

Because the appearance can resemble other genital ulcer diseases, examining a sample of the lesion tissue is used to confirm the diagnosis.

Left untreated

Why granuloma inguinale (donovanosis) is worth catching early

Treated early, granuloma inguinale (donovanosis) clears with antibiotics and causes no lasting harm. Left untreated, it can climb into the reproductive tract and beyond:

Relapse after treatment

Even after apparently effective treatment, the infection can relapse 6 to 18 months later. Follow-up and awareness of this possibility are important.

How testing works

How a granuloma inguinale (donovanosis) test works

Granuloma Inguinale (Donovanosis) is detected with a nucleic-acid amplification test (NAAT) — the most accurate method — on a urine sample or a swab. You can do it at a lab, a clinic, or at home.

When to test

Seek evaluation as soon as a persistent or unexplained genital ulcer appears.

After treatment

There is no routine screening blood test described for donovanosis; diagnosis depends on the appearance of the ulcers and examination of lesion tissue.

Clinical examination of the ulcer First step
Sample
Visual inspection of the genital/perineal lesion
Results
At the visit

Diagnosis begins with recognizing the characteristic beefy-red, painless, easily bleeding ulcer.

Tissue examination Most accurate
Sample
Sample of the lesion tissue
Results
Varies by laboratory

Diagnosis is confirmed by examining a sample of the lesion tissue.

What it costs: Varies by clinic and whether a biopsy or tissue sample is needed..

If your result is positive

How is granuloma inguinale (donovanosis) treated?

Granuloma inguinale is curable but requires a long antibiotic course, continued until all lesions have fully healed.

Treat partners

Sexual partners should be evaluated.

Re-test after treatment

Relapse can occur 6 to 18 months later even after apparently effective treatment, so monitor for return of lesions and seek re-evaluation if they recur.

Treatment & online care

Resistance note: Treatment should continue until lesions fully heal; stopping early may leave infection that has not resolved.

Prevention

How to prevent granuloma inguinale (donovanosis)

  • Avoid contact with ulcers

    Since the infection spreads through sexual contact and the ulcers transmit the bacteria, avoiding contact with genital sores reduces risk.

  • Evaluate and treat partners

    Having sexual partners evaluated when a diagnosis is made helps interrupt transmission.

  • Complete the full antibiotic course

    Finishing treatment until all lesions heal lowers the chance of unresolved infection and ongoing transmission.

Who is most at risk

Who is most at risk for granuloma inguinale (donovanosis)?

Anyone who is sexually active can contract granuloma inguinale (donovanosis), but certain groups face significantly higher risk — and should test more frequently.

Sexual contact in endemic regions
The infection is concentrated in a few tropical and subtropical regions, so sexual contact in those areas raises the likelihood of exposure.
Contact with an infected partner's ulcers
Because the infection spreads through sexual contact, exposure to a partner's lesions is the primary risk.

Why it matters

Why STD testing matters

Find granuloma inguinale (donovanosis) testing
  • Genital ulcers have many causes, and accurate diagnosis guides the right treatment.
  • Donovanosis is curable, but only with a long enough antibiotic course.
  • The ulcers are painless, so the infection can spread without obvious warning.
  • Relapse can occur months after treatment, making follow-up important.
  • Confirming the diagnosis with tissue examination avoids misattribution to other conditions.

Good to Know

Granuloma Inguinale (Donovanosis) testing FAQs

Common questions about granuloma inguinale (donovanosis) and granuloma inguinale (donovanosis) testing, answered.

What is granuloma inguinale (donovanosis)?

Granuloma inguinale, also called donovanosis, is a rare bacterial sexually transmitted infection caused by <em>Klebsiella granulomatis</em>. It causes painless, slowly growing, beefy-red ulcers that bleed easily, usually on the genitals or perineum.

Is donovanosis common in the United States?

No. It is very uncommon in the United States and is seen mostly in a few tropical and subtropical regions.

How does donovanosis spread?

Granuloma inguinale spreads through sexual contact, including contact with the open, bleeding ulcers.

Does donovanosis cause swollen lymph nodes?

Typically not. Donovanosis usually occurs without the swollen lymph nodes that some other ulcer-causing STIs produce, which is one feature that helps distinguish it.

How is donovanosis diagnosed?

Diagnosis is based on the characteristic appearance of the ulcers and is confirmed by examining a sample of the lesion tissue.

Is donovanosis curable?

Yes, it is curable, but it requires a long antibiotic course — azithromycin (1 g once weekly or 500 mg daily) for at least 3 weeks and until all the lesions have fully healed.

Can donovanosis come back after treatment?

Yes. Relapse can occur 6 to 18 months later even after apparently effective treatment, so it's important to watch for recurring lesions and seek re-evaluation if needed.

Are the ulcers from donovanosis painful?

No. The ulcers are characteristically painless. They are beefy-red, grow slowly, and bleed easily on contact.
