Bacterial defense
Bacteria protect themselves in a variety of ways.
v Biofilm
There are bacteria that secrete substances that attach to bacteria and other cells. Together with bacteria, it forms an adhesive layer called a biofilm.
v Capsular
Some bacteria protect themselves by using capsules called capsules. The capsules resist infection and block the function of white blood cells that feed on bacteria. Such bacteria are described as capsules.
v Adventitia
Gram-negative bacteria have an outer membrane beneath the capsule that protects the bacteria against certain antibiotics. When this outer membrane is destroyed, a toxin called endotoxin is released. In gram-negative bacterial infections, endotoxin helps exacerbate symptoms.
v Spore
Some bacteria form inactive (latent) spores. From spores, it can survive in harsh environments. In a better environment, the spores germinate as active bacteria.
Resistant bacteria are transmitted from animals to humans. Resistant bacteria are common in cattle because antibiotics are regularly prescribed to healthy cows to prevent infections that inhibit growth and cause disease. Many states ban the use of antibiotics for animals to avoide the following risks:
- Danger of swallowing resistant bacteria in livestock meat and processed products.
- Risk of contamination by resistant strains due to contact with animals
- Risk of exposure to antibiotics in beef and processed products
Bacterial infection
Bacterial infectious diseases are classified according to several methods for classifying bacteria. For example, it can be classified as a gram-negative or gram-positive infection, and it is important to make this distinction. Because different types of antibiotics may be needed to treat these two types of infections.
v Infections caused by Gram-negative bacteria include:
- Brucellosis
- Campylobacter infection
- Cat scratch disease
- cholera
- coli infection
- Gonorrhea infection
- Reason of Infectious diseases are Klebsiella, Enterobacter, and Serratia bacteria
- Legionella infection
v Infections caused by Gram-positive bacteria include:
- Anthrax
- diphtheria
- Enterococcal infection
- Eligiperoslix disease
- Listeriosis
Some infectious diseases are categorized by the shape of the bacteria. For example, infections caused by spirochete (spiral bacteria) are classified as spirochete infections.
Spirochetes infections include:
- Begel, strawberry tumor, pinta
- Leptospirosis
- Lyme disease
- Rat-bite fever
- Relapsing fever
- syphilis
Infections can also be categorized based on whether the infectious bacteria need oxygen or can live without it. If it requires oxygen to survive is called aerobic bacteria. Bacteria that do not need oxygen to live and multiply are called anaerobic bacteria.
