Bacterial infection of oral cavity - scarlet fever and tuberculosis
Scarlet fever is a bacterial infection caused by group A Streptococcus bacteria, specifically Streptococcus pyogenes. It is characterized by a distinctive rash and is most commonly seen in children between the ages of 5 and 15 years. Scarlet fever is highly contagious and can be transmitted through respiratory droplets from infected individuals.
Symptoms:
- Sore throat: The infection usually begins with a sore throat, accompanied by difficulty swallowing and swollen tonsils.
- Fever: High fever is common and can reach up to 101°F (38.3°C) or higher.
- Scarlet rash: A characteristic rash appears on the skin within 1-2 days after the onset of the infection. The rash looks like tiny, red pinpricks and feels rough to the touch. It typically starts on the neck and chest and spreads to other parts of the body, sparing the face but often affecting the cheeks, creating a flushed appearance with a pale area around the mouth.
- Strawberry tongue: The tongue may become swollen and appear red, with a "strawberry-like" appearance, characterized by enlarged taste buds and a red or white coating.
- Pastia's lines: In some cases, red or pink lines may appear in the skin creases, such as the underarms, groin, and elbow bends.
Treatment:
Scarlet fever is treated with antibiotics, usually penicillin or amoxicillin. Early treatment is crucial to prevent complications and reduce the spread of the infection to others. It's essential for patients to complete the entire prescribed course of antibiotics even if they start feeling better.
Complications:
Prompt and appropriate treatment of scarlet fever usually prevents severe complications. However, if left untreated, or in certain cases, complications may arise, including:
- Rheumatic fever: An inflammatory condition that can affect the heart, joints, skin, and nervous system.
- Kidney problems: Acute post-streptococcal glomerulonephritis, a kidney disorder, may occur in some cases.
- Ear infections: Middle ear infections can develop as a secondary infection.
- Skin infections: Impetigo, a bacterial skin infection, may occur in some cases.
Prevention:
Practicing good hygiene, such as frequent handwashing, covering the mouth and nose when sneezing or coughing, and avoiding close contact with infected individuals, can help prevent the spread of scarlet fever.

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also target other parts of the body, such as the kidneys, spine, and brain. TB is a significant global health concern, and it spreads through the air when an infected person coughs or sneezes, releasing bacteria-containing droplets into the air.
Symptoms:
- Persistent cough: A cough that lasts for more than two weeks or produces blood-tinged sputum is a common symptom of pulmonary TB.
- Fatigue: Feeling weak or tired despite adequate rest and sleep.
- Fever: Low-grade fever, especially during the evening.
- Night sweats: Experiencing excessive sweating during sleep, soaking the bedclothes.
- Unintentional weight loss: A decrease in weight without intentional dieting or exercise.
- Loss of appetite: Reduced desire to eat.
- Chest pain: Pain or discomfort in the chest area, especially during breathing or coughing.
Diagnosis:
TB can be diagnosed through various methods, including:
- Tuberculin Skin Test (TST): An injection of tuberculin under the skin, followed by the observation of a delayed hypersensitivity reaction.
- Interferon-Gamma Release Assays (IGRAs): Blood tests that detect the release of interferon-gamma in response to TB-specific antigens.
- Chest X-ray: To detect abnormalities in the lungs.
- Sputum Tests: Examination of sputum samples for the presence of TB bacteria.
Treatment:
The treatment of TB involves a combination of antibiotics, typically taken for six to nine months. It's crucial to complete the full course of treatment to ensure successful eradication of the bacteria and reduce the risk of drug resistance.
Prevention:
Preventing the spread of TB involves a combination of measures, such as:
- TB vaccination (BCG vaccine): In some countries, the Bacillus Calmette-Guérin (BCG) vaccine is used to protect against severe forms of TB in children.
- Infection control measures: Proper ventilation and the use of masks by infected individuals can help reduce transmission.
- Early detection and treatment: Prompt identification and treatment of TB cases can prevent further spread of the disease.
TB is a major global public health challenge, and efforts are ongoing to control its spread through improved diagnosis, treatment, and prevention strategies. If you suspect you have TB or have been in contact with an infected individual, it's essential to seek medical attention promptly for evaluation and appropriate management.
1. Oral Ulcers: Painful, non-healing ulcers may develop on the oral mucosa. These ulcers can be solitary or multiple and may have irregular borders.
2. Granulomatous Gingivitis: Tuberculous gingivitis can lead to red, swollen, and bleeding gums due to granulomatous inflammation.
3. Tuberculous Cheilitis: Involvement of the lips may lead to tuberculous cheilitis, characterized by fissures, crusting, and swelling.
4. Lymphadenopathy: Enlarged lymph nodes in the neck (cervical lymphadenopathy) may be present in cases of oral TB.
5. Tuberculous Sialadenitis: The salivary glands may be affected, resulting in pain and swelling in the affected region.
6. Palatal Tuberculosis: In some cases, tuberculosis can involve the hard or soft palate, leading to ulceration and palatal perforation.
7. Tuberculous Glossitis: The tongue may show signs of tuberculous infection, with ulcerations and swelling.
It's important to note that these oral manifestations of tuberculosis can mimic other oral diseases, such as oral cancer, fungal infections, or other bacterial infections. Therefore, a definitive diagnosis requires a thorough evaluation by a healthcare professional. Biopsy and laboratory tests are often necessary to confirm the presence of tuberculosis bacteria in oral tissues.
Treatment of oral tuberculosis involves a combination of anti-tuberculosis drugs, similar to the treatment for pulmonary tuberculosis. Early detection and prompt treatment are essential to prevent the spread of the disease to other parts of the body and to reduce potential complications.
If you notice any unusual oral symptoms or have a history of tuberculosis or exposure to TB, it's essential to seek medical attention for proper evaluation and diagnosis.
