Bacillus cereus is a spore-producing rod-shaped, gram-positive bacterium. It releases toxins that result in vomiting or diarrhea. Bacillus cereus infections are self-limiting, mild, and harmless. Some strains of this bacterium are beneficial as it is used as probiotics for animals. Bacillus cereus is a food-borne bacteria. It also found in soil. It causes fried rice syndrome. Spore formation causes it to survive adverse environments including normal cooking temperatures. This bacterium is also resistant to alcohol treatment. Few strains of this bacterium produce bacteriocins used to kill the other strains of Bacillus cereus or other gram-positive bacteria.
The increased rate of foodborne disease has become a great concern over the world. Every year millions of people are infected with foodborne pathogens, get hospitalized and die due to the consumption of foods along with a variety of foodborne pathogens transmitted onto foods. There are several bacteria that cause foodborne disease associated with various food, we consume every day. In this context, a list of foodborne disease has been discussed along with the associated infectious bacteria and foods they found. This list of foodborne disease makes you understand the symptoms of food poisoning, foods, hygeine, and bacteria.
We were 5th batch both in the microbiology department and in the university. After orientation class, the first lecture of our whole university life was delivered in Room No 304 of Bangabandhu Academic Building. It was the most beautiful room in the Microbiology department. We were waiting for our teacher to enter the room. On that day we didn’t know all of our friends (total of 35 students). I only introduced with 4/5 friends.
What is Endosymbiotic theory ?
Endosymbiotic theory stats that, the modern eukaryotic cells (mitochondria ) evolved in steps through inter-cooperation into cells from a nuclear line of descendants of chemoorganotrophic and phototrophic symbionts.
It states that Mitochondria and Chloroplast were free-living bacteria that established residency in the primitive eukaryotic cells, eventually yielding the modern eukaryotic cell.
Antibiotic resistance is increasing day by day over the world and this will cause a dramatic danger to the human civilization. It is now suspected that millions of people will die due to the increasing antibiotic resistance by 2050. Therefore, this increased resistance emphasizes the researchers to find new antimicrobial agents for combating microbial diseases. This article describes 15 antibiotic alternatives some of which may have strong antimicrobial effectiveness against microbial infection.
