Morganella Morganii: Causes, Symptoms, and Treatment - Urology

More Info

---

Morganella morganii is a Gram-negative bacterium that is part of the Enterobacteriaceae family, which includes other well-known pathogens such as Escherichia coli. This organism is commonly found in the intestinal tract of humans and animals, and while it is typically non-pathogenic, it can become opportunistic and cause infections, particularly in individuals with compromised immune systems or underlying health conditions.


Causes of Morganella morganii Infection
Morganella morganii infections can occur through various routes, including:
1. Endogenous Infection: This is the most common route, where the bacteria, normally present in the gut, translocate to other areas of the body, such as the urinary tract, leading to infections like urinary tract infections (UTIs) or urethritis.

2. Healthcare-Associated Infections: Morganella morganii can be transmitted in healthcare settings, particularly among patients with invasive devices (like catheters) or those undergoing surgical procedures.

3. Contaminated Food or Water: Although less common, ingestion of contaminated food or water can also lead to gastrointestinal infections, which may subsequently result in urogenital infections.


Symptoms of Morganella morganii Infection
Infections caused by Morganella morganii can manifest in various ways, depending on the site of infection. Common symptoms associated with urinary tract infections include:
- Dysuria: Painful urination
- Increased Urgency and Frequency: A strong need to urinate frequently
- Urethral Itching or Discomfort: This can be a symptom of urethritis, which may present as itching or irritation in the urethra.

- Lower Abdominal Pain: Discomfort in the lower abdomen may also occur.

- Fever and Chills: In more severe cases, systemic symptoms may develop.


Treatment of Morganella morganii Infection
The treatment for a Morganella morganii infection typically involves the use of antibiotics. However, antibiotic resistance is a growing concern with this organism, so susceptibility testing is often necessary to determine the most effective antibiotic. Commonly used antibiotics may include:
- Trimethoprim-sulfamethoxazole (TMP-SMX)
- Ciprofloxacin
- Piperacillin-tazobactam
In cases where the infection is mild, the healthcare provider may recommend symptomatic treatment, such as increased fluid intake and over-the-counter pain relief medications.


Addressing Urethral Itching
If you are experiencing urethral itching, it could be a direct symptom of the infection or a result of irritation. It is essential to consult with a healthcare provider for a proper diagnosis and treatment plan. They may recommend:
- Antibiotics: To clear the infection.

- Topical Treatments: To alleviate itching, if appropriate.

- Hydration: Drinking plenty of fluids can help flush out the urinary tract.


Conclusion
In summary, Morganella morganii can cause urinary tract infections and may lead to symptoms such as urethral itching. The infection is typically treated with antibiotics, and it is crucial to consult a healthcare professional for an accurate diagnosis and appropriate treatment. If you have isolated this organism in your semen analysis, it is advisable to discuss the findings with your doctor, who can provide guidance on the next steps, including potential treatment options and further investigations if necessary.
