🧪 Culture & Sensitivity – Aerobic Bacteria (Semen Sample)
🔍 Overview
This test is used to detect the presence of aerobic bacterial infections in the semen, particularly in cases of male infertility, chronic prostatitis, epididymitis, or urogenital tract infections. It also assesses antibiotic susceptibility to guide appropriate treatment.
📦 Sample & Technical Details
Parameter | Details |
|---|---|
Sample Type | Semen |
Collection Method | Collected via masturbation into a sterile container |
Pre-Test Prep | Abstain from ejaculation for 2–5 days before sample collection |
Fasting Required | ❌ No |
Processing Time | 48–72 hours (culture), 5–7 days (final report with sensitivity) |
Lab Department | Microbiology |
🎯 Purpose of the Test
Used When | Purpose |
|---|---|
Male infertility evaluation | Rule out infection that affects sperm function |
Painful ejaculation, pelvic discomfort | Diagnose chronic prostatitis |
Urogenital infection symptoms (burning, frequency, etc.) | Confirm and identify causative organisms |
Post-vasectomy or post-surgical infections | Detect secondary infections |
🦠 Common Pathogens Identified
Organism | Clinical Significance |
|---|---|
Escherichia coli | Most common uropathogen |
Staphylococcus aureus | Often in chronic prostatitis or abscesses |
Enterococcus faecalis | Common in older males with urologic conditions |
Pseudomonas aeruginosa | Especially in hospital-acquired infections |
Klebsiella pneumoniae | Opportunistic urogenital pathogen |
Streptococcus species | Occasionally detected |
💊 Antibiotic Sensitivity Testing (AST)
- Identifies which antibiotics are effective against the isolated bacteria.
- Sensitivity reported as:
- S – Sensitive
- I – Intermediate
- R – Resistant
Common antibiotics tested:
- Ciprofloxacin
- Norfloxacin
- Doxycycline
- Amoxicillin-Clavulanate
- Nitrofurantoin
- Gentamicin
📊 Interpreting Results
Result | Interpretation |
|---|---|
✅ No Growth | No bacterial infection detected |
❌ Positive Culture | Indicates infection – follow antibiotic sensitivity report |
⚠️ Contaminants | Possible improper sample collection (e.g., contact with skin) |
🧪 Recommended Additional Tests
Test | Purpose |
|---|---|
Semen Analysis | Assess sperm count, motility, morphology |
Prostate Specific Antigen (PSA) | If chronic prostatitis is suspected |
Urine Culture (Post-ejaculate) | Rule out concurrent urinary infection |
Urethral Swab Culture | If symptoms point to anterior urethritis |
STI Panel (Chlamydia, Gonorrhea) | Especially if high-risk exposure or recurrent infections |
🧠 Clinical Importance
- Bacterial prostatitis or seminal vesiculitis can reduce sperm motility and viability.
- Early treatment prevents chronic complications like infertility or recurrent UTIs.
- Essential before assisted reproduction (IVF, IUI) to prevent embryo contamination.
