BACILLUS MALARIAE Meaning and
Definition
-
Bacillus malariae is a microbiological term that refers to a particular species of bacteria known as Bacillus cereus biovar anthracis. The bacterium is most commonly associated with causing anthrax, a severe and potentially fatal disease in humans and animals. Bacillus malariae is gram-positive and rod-shaped, exhibiting mobility through the use of flagella.
The bacteria possess the ability to form endospores, highly resistant structures that allow them to survive under harsh conditions such as extreme temperatures, low nutrient availability, and exposure to chemicals. Bacillus malariae bacteria are typically found in soil and can infect humans and animals through direct contact with contaminated materials, ingestion, or inhalation of spores present in the environment.
In humans, Bacillus malariae infections may manifest as three different forms of anthrax depending on the mode of entry: cutaneous, gastrointestinal, or respiratory. Cutaneous anthrax occurs through skin contact with spores, resulting in skin lesions and ulcers. Gastrointestinal anthrax is obtained through ingestion of contaminated meat, leading to severe abdominal pain, vomiting, and bloody diarrhea. Respiratory anthrax occurs when spores are inhaled, causing flu-like symptoms that can progress to severe respiratory distress and systemic infection.
Given the potential for high morbidity and mortality rates associated with Bacillus malariae infections, prompt medical attention and appropriate antibiotic treatment are essential. Additionally, measures to prevent exposure to contaminated materials and proper handling and disposal of animal carcasses are crucial for disease prevention and control.
Etymology of BACILLUS MALARIAE
The word "Bacillus malariae" is a combination of two separate terms: "bacillus" and "malariae".
1. Bacillus: The term "bacillus" originates from Latin, where "bacillum" means a small staff or wand. This term was first used by German scientist Ferdinand Cohn in 1875 to describe rod-shaped bacteria. Since then, "bacillus" has been widely used to refer to various rod-shaped bacteria.
2. Malariae: The term "malariae" dates back to ancient Rome, where "mal" means bad and "aria" signifies air. It was believed that the disease was caused by "bad air" or miasma. The term "malaria" specifically refers to a febrile illness caused by Plasmodium parasites, transmitted through the bites of infected mosquitoes.
