List Of Gram Negative Bacteria And Their Diseases Pdf
Gram-negative bacteria are a group of bacteria that can cause serious infections in humans. They contain a cell wall that makes them resistant to many antibiotics, making them difficult to treat. Here is a list of the most common gram-negative bacteria and the diseases they can cause in humans.
1. Escherichia coli (E. coli)
Escherichia coli, commonly known as E. coli, is a gram-negative bacteria found in the human intestine. While most strains of E. coli are harmless, some can cause serious infections. Common symptoms of E. coli infection include diarrhea, abdominal pain, and fever. In severe cases, it can lead to kidney failure.
2. Salmonella
Salmonella is a gram-negative bacteria commonly found in contaminated food and water. Symptoms of salmonella infection include diarrhea, abdominal cramps, and fever. In severe cases, it can lead to dehydration and hospitalization. Salmonella infection is commonly referred to as "food poisoning."
3. Pseudomonas aeruginosa
Pseudomonas aeruginosa is a gram-negative bacteria found in soil, water, and some hospital environments. It can cause infections in people with weak immune systems or those with open wounds. Symptoms of Pseudomonas aeruginosa infection include skin infections, urinary tract infections, and pneumonia.
4. Klebsiella pneumoniae
Klebsiella pneumoniae is a gram-negative bacteria found in the human intestine. It can cause infections in the lungs, bloodstream, and urinary tract. Symptoms of Klebsiella pneumoniae infection include fever, chills, and coughing up phlegm.
5. Legionella pneumophila
Legionella pneumophila is a gram-negative bacteria found in water. It can cause Legionnaires' disease, which is a serious type of pneumonia. Symptoms of Legionnaires' disease include fever, chills, cough, and shortness of breath.
6. Helicobacter pylori
Helicobacter pylori is a gram-negative bacteria found in the stomach. It can cause stomach ulcers and stomach cancer. Symptoms of Helicobacter pylori infection include abdominal pain, bloating, and weight loss.
7. Neisseria gonorrhoeae
Neisseria gonorrhoeae is a gram-negative bacteria that causes gonorrhea, which is a sexually transmitted infection. Symptoms of gonorrhea include painful urination and discharge from the genitals in both men and women.
8. Haemophilus influenzae
Haemophilus influenzae is a gram-negative bacteria that can cause ear infections, sinus infections, and pneumonia in children. Symptoms of Haemophilus influenzae infection include fever, cough, and ear pain.
9. Bordetella pertussis
Bordetella pertussis is a gram-negative bacteria that causes whooping cough. Symptoms of whooping cough include severe coughing spells followed by a "whooping" sound when inhaling. It can be especially dangerous in infants and young children.
10. Vibrio cholerae
Vibrio cholerae is a gram-negative bacteria that causes cholera, which is a severe diarrhea and dehydration illness. It is typically spread through contaminated water and can be deadly if left untreated. Symptoms of cholera include watery diarrhea, nausea, and vomiting.
In conclusion, gram-negative bacteria are a serious threat to human health. It is important to take precautions such as washing your hands regularly, cooking food thoroughly, and avoiding contact with contaminated water sources to prevent infections caused by these bacteria.
