Salmonella typhi causing typhoid and Clostridium tetani causing tetanus are which type of bacteria?

Explanation

Option A is correct.Salmonella typhi and Clostridium tetani are both bacilli. Bacilli are rod-shaped bacteria. They are one of the three main shapes of bacteria, along with cocci (spherical bacteria) and spirilla (spiral bacteria). Bacilli are found in a wide variety of environments, including soil, water, and the human body. Some bacilli are beneficial, such as those that produce lactic acid in yogurt and cheese. Other bacilli are pathogens, which means that they can cause disease. Salmonella typhi and Clostridium tetani are both examples of pathogenic bacilli. Salmonella typhi causes typhoid, a serious disease that can be fatal if it is not treated. Typhoid is transmitted through contaminated food and water. It causes fever, headache, and diarrhea. Clostridium tetani causes tetanus, a disease that affects the nervous system. Tetanus is caused by a toxin that is produced by the bacteria. The toxin causes muscle spasms, which can be severe and life-threatening. Tetanus is transmitted through contact with contaminated soil or other objects. Both Salmonella typhi and Clostridium tetani can be prevented by vaccination. The typhoid vaccine is recommended for people who are traveling to areas where typhoid is common. The tetanus vaccine is recommended for everyone as part of the routine childhood immunization schedule.Spirilla:Spiral bacteria.Example; Campylobacter (food poisoning), Leptospira (leptospirosis), Treponema pallidum (syphilis) Cocci: Spherical bacteria.Examples; Streptococcus (strep throat), Staphylococcus (staph infection), Neisseria (meningitis, gonorrhea) Comma-shaped bacteria are a type of spirilla. Comma-shaped bacteria include: Vibrio cholerae (cholera), Vibrio parahaemolyticus (food poisoning), and Helicobacter pylori (stomach ulcers).
