Dr. Chen Ming reply Rare Disease

Hello, Xiaoling.
I apologize for the delay in responding to your message, as I was working at National Taiwan University Hospital for the entire last year and have just returned to Changhua Christian Hospital.
Regarding the organism you referred to as "伽氏桿菌," its scientific name is Trichomonas vaginalis, which is more commonly known in Chinese as "陰道滴蟲" (vaginal trichomoniasis).
The white discharge that women often refer to is typically due to an abnormal overgrowth of microorganisms that are normally part of the vaginal microbiota.
The most common causes include fungal infections (especially Candida albicans), bacterial infections (bacterial vaginosis), and trichomoniasis, each requiring different treatments.

The most effective medication for trichomoniasis is Flagyl (generic name Metronidazole), which is available in both vaginal suppository and oral forms.
It is crucial for both partners to be treated simultaneously to eliminate the infection completely, as men are often asymptomatic.
If the woman is treated but the male partner is not, the infection can be transmitted back to her, creating a cycle of reinfection.
Therefore, it is essential to encourage male partners to take oral Flagyl for one to two weeks.
Otherwise, patients frequently report persistent or recurrent infections.
If you are referring to Gardnerella vaginalis, which is what you called "伽氏桿菌," it is a type of bacterial infection known as bacterial vaginosis.
Treatment with the suppository Tasultin for one week can effectively cure this condition, and since it is less likely to infect men, treating the female partner alone is usually sufficient.

More Info

Gai's Bacillus, also known as Bacillus cereus, is a type of bacteria that can cause foodborne illnesses. It is commonly found in soil, vegetation, and the gastrointestinal tract of humans and animals. Bacillus cereus is known for its ability to produce toxins that can lead to two main types of illnesses: emetic (vomiting) and diarrheal syndromes. The emetic type is often associated with rice dishes, particularly fried rice that has been cooked and kept warm for long periods, while the diarrheal type is linked to a variety of foods, including meats, vegetables, and dairy products.

Prevention of Bacillus cereus Infection
Preventing infection from Bacillus cereus primarily revolves around proper food handling and hygiene practices. Here are some key preventive measures:
1. Proper Cooking: Ensure that food is cooked to the appropriate temperatures to kill any bacteria present. For example, rice should be cooked thoroughly and served hot.

2. Immediate Refrigeration: Leftover food should be refrigerated promptly, ideally within two hours of cooking. Bacteria can multiply rapidly at room temperature.

3. Reheating: When reheating food, ensure it reaches a temperature of at least 165°F (74°C) to kill any bacteria that may have developed during storage.

4. Good Hygiene Practices: Wash hands thoroughly with soap and water before handling food, and ensure that cooking surfaces and utensils are clean.

5. Avoid Cross-Contamination: Use separate cutting boards for raw meats and other foods to prevent cross-contamination.

6. Storage: Store food in shallow containers to allow for quick cooling and prevent the growth of bacteria.

Treatment of Bacillus cereus Infection
If a person becomes ill due to Bacillus cereus, treatment typically focuses on managing symptoms, as most cases are self-limiting. Here are the common approaches to treatment:
1. Hydration: The most important aspect of treatment is to maintain hydration, especially in cases of diarrhea or vomiting. Oral rehydration solutions can be beneficial.

2. Symptomatic Relief: Over-the-counter medications may be used to relieve symptoms such as nausea and diarrhea. However, it is essential to consult a healthcare provider before taking any medication, especially in children or individuals with underlying health conditions.

3. Antibiotics: In severe cases, particularly if the infection leads to more serious complications such as bacteremia or if the patient is immunocompromised, antibiotics may be necessary. However, Bacillus cereus is often resistant to many common antibiotics, so treatment should be guided by a healthcare professional based on sensitivity testing.

4. Medical Attention: If symptoms are severe or persistent, it is crucial to seek medical attention. This is particularly important for vulnerable populations, such as the elderly, young children, or individuals with weakened immune systems.

Conclusion
Understanding Gai's Bacillus (Bacillus cereus) is essential for preventing foodborne illnesses associated with this bacterium. By adhering to proper food safety practices, individuals can significantly reduce the risk of infection. In the event of illness, supportive care and hydration are typically sufficient, but medical attention should be sought for severe cases or complications. Awareness and education about food handling and hygiene are key components in preventing Bacillus cereus infections and ensuring public health safety.
