For bubos, a needle and syringe should be used to aspirate pustular material from the bubo though normal tissue (eg, insert needle above bubo through normal tissue - this will prevent chronic leakage of the fluid and reduces contamination).

A bubo (Greek βουβών, boubṓn, 'groin') is adenitis or inflammation of the lymph nodes and is an example of reactive infectious lymphadenopathy. [1] Buboes are a symptom of bubonic plague and occur as painful swellings in the thighs, neck, groin or armpits. [2] .

Lymph node aspirate: An affected bubo typically contains numerous organisms that can be evaluated microscopically and by culture. Blood: Routine blood cultures are a sensitive means of detecting Y. pestis. In later stages of disease, levels of bacteremia are high enough that organisms may occasionally be seen by microscopy on blood smears.

Feb 1, 2012 · To diagnose lymphogranuloma venereum, genital swabs or bubo aspirate may be tested for C. trachomatis serotypes L1, L2, and L3 by culture, direct immunofluorescence, or nucleic acid...

In the case of plague, the F1RDT detects the F1 capsular antigen of Y. pestis, which is present in large amounts in buboes, blood and sputum from infected patients. The test is performed on sputum from patients with suspected pneumonic plague and on bubo aspirate from patients with suspected bubonic plague.

When handling the bubo aspirate and blood, laboratory personnel must use gloves and care to avoid aerosolization of these infected fluids. Laboratory workers who process the cultures should be alerted to take precautions; however, standard bacteriologic techniques that safeguard against skin contact with and aerosolization of cultures should be ...

A bubo or swelling of regional lymph nodes becomes apparent in the groin, axilla, or neck within the first day. Buboes vary from 1 to 10 cm and elevate the overlying skin, which may be warm and erythematous.

Aug 25, 2015 · Bubonic plague, resulting from the bite of an infected flea, accounts for approximately 80%–85% of cases; patients develop a "bubo," a painful swelling of one or several lymph nodes that progresses during the first few days of illness.

Aspiration of fluctuant buboes using a wide bore needle through adjacent healthy skin every second or third day. An incision and drainage should not be attempted. If buboes persist, the patient should be referred. Sequelae such as strictures and/or fistula may require surgery.
