Definition: Actinomycosis (or Acinar Aspergillosis) is an infectious fungal infection that affects the lining of the intestines (entera). It's caused by fungi called aspergilloma, which can infect any part of the body. The exact cause of this infection isn't well understood. Some people have it naturally, while others get it from exposure to contaminated soil or water. The immune system has a natural defense against Aspergillus fumigatus, which is common in contaminated soil and may be transferred into the body through food or contact with infected animals. The symptoms of actinomycosis are typically mild but can include: - Weight loss - Fatigue - Increased appetite - Diarrhea (constipation) - Nausea - Loss of taste or smell - Fever - Headache - Nervous system problems The infection is usually treated with antifungal agents like fluconazole. They typically don't cause any side effects and are generally safe to use. It's important to be aware that actinomycosis can spread through the air, so people should avoid exposure to contaminated soil or water if possible. It's also important for those who have it to inform their healthcare provider if they develop symptoms of illness such as diarrhea or fever, especially in cases where the infection is likely to spread. If you suspect you may be infected with Aspergillus fumigatus, you should take immediate action by seeking medical advice from a doctor.
