Do You Know About Gram-negative Bacteria? Quiz

The symptoms of Salmonella Typhi include invasion of lymph nodes, necrosis of intestinal lymphatic tissue, high fever, vomiting, diarrhea, and the presence of Peyer's patches. These symptoms are characteristic of typhoid fever, which is caused by the Salmonella Typhi bacteria.

The symptoms of Enterocolitis caused by Samonella Enterica include fever, chills, headache, malaise (muscle pains), diarrhea, abdominal pain, vomiting, and rarely causes septicemia.

Bortella Pertussis is a subdivision of Alcaligenaceal that causes Whooping cough. It destroys the ciliated cells in the trachea and bronchi, leading to mucus buildup and a violent cough. It possesses four virulence factors that contribute to its pathogenicity. The heat killed organism is included in the DPT vaccine, which helps to provide immunity against Pertussis.

Shingalle Dysentery can be found in tropical areas with poor sanitation. This is because the disease is commonly transmitted through contaminated food and water, and in areas with poor sanitation, the risk of contamination is higher. Tropical areas also provide an ideal environment for the growth and spread of the bacteria or parasites that cause Shingalle Dysentery. Therefore, the combination of tropical climate and poor sanitation increases the likelihood of encountering this disease in those regions.

Campylobacter jejuni can be obtained from the normal flora in birds. This bacterium is commonly found in the intestines of birds, such as chickens, turkeys, and ducks, without causing any harm to them. However, if contaminated meat or poultry is consumed or proper food handling and cooking practices are not followed, Campylobacter jejuni can cause foodborne illness in humans. Therefore, it is important to handle and cook poultry properly to prevent infection.

Enteroinvasive E. coli is a lactose fermenter that causes bloody diphtheria. This bacterium is able to invade the intestinal cells, leading to inflammation and damage. The presence of blood in the diphtheria is due to the invasion and destruction of the blood vessels in the affected area. Other lactose fermenters may cause different types of infections, but in this case, it is specifically Enteroinvasive E. coli that is responsible for the bloody diphtheria.

E. Coli O157 H7 can cause Neonatal meningitis.

Vibriocholerae can be found in waterborne sources such as contaminated water. It can also be present in shellfish, clams, and raw oysters that have been exposed to contaminated water.

Entertoxogenic E. Coli is the correct answer because it is a Gram-negative bacterium that can ferment lactose and cause travelers' diarrhea. This type of E. Coli produces toxins that can lead to gastrointestinal symptoms such as diarrhea, abdominal pain, and vomiting. It is commonly associated with contaminated food or water, and is a common cause of diarrhea in travelers to developing countries.

The correct answer is Enteroheamorrage E.Coli and Shinga Toxins. Enteroheamorrage E.Coli is a type of bacteria that can cause a severe illness called Hamburger disease. It is a lactose fermenter, meaning it can break down lactose sugar. In addition to causing illness, Enteroheamorrage E.Coli produces Shiga toxins, which are responsible for the symptoms associated with the disease. These toxins can damage the lining of the intestines and lead to symptoms such as bloody diarrhea and abdominal pain.

Salmonella Enterica can be found in uncooked chicken, poorly handled foods, and drinks. It takes approximately 10^5 bacterial cells or 20-24 hours of exposure to become infectious. However, in immunocompromised individuals, it only takes 10^3 bacterial cells to cause an infection.

Salmonella Typhi can be found in tropical areas, contaminated water, shellfish, and contaminated milk. In order to be infectious, it takes a minimum of 10^6 of the bacteria. This means that a person needs to ingest at least one million bacteria to become infected with Salmonella Typhi.

The symptoms of the slightly comma-shaped Vibrio campylobacter species Vibriocholerae include decreased absorption of sodium, which leads to diarrhea. This means that the body is unable to properly absorb sodium from the intestines, resulting in loose and watery stools. This can cause dehydration and electrolyte imbalances if not treated promptly.

Campylobacter jejuni is a bacterial infection that commonly causes enteritis, which is inflammation of the small intestine. The symptoms of Campylobacter jejuni infection include fevers, chills, muscle pain (myalgia), and diarrhea. These symptoms are typical of enteritis caused by this bacterium.

Pseudomonas aeruginosa is a bacterium that thrives in damp environments such as shower heads and humidifiers. It is considered an opportunistic pathogen, meaning it can cause infections in individuals with compromised immune systems, such as those with cystic fibrosis or burn injuries. However, it does not typically cause infections in healthy individuals. Pseudomonas aeruginosa is known for its natural resistance to antibiotics, making it difficult to treat.

Psedomas cepcia is a type of bacteria that thrives in moist environments such as shower heads and humidifiers. It is known to infect individuals with cystic fibrosis and can multiply in low nutrient environments that contain saline and water. One notable characteristic of Psedomas cepcia is its natural immunity to antibiotics.

Haemophilus influenza is a bacterium that typically resides in the nasopharynx as part of the normal flora. However, it can become an opportunistic pathogen, causing various infections such as meningitis, pneumonia, and joint infections.

Legionella is a type of bacteria that thrives in water, particularly in shower heads and water tanks. It has the potential to cause pneumonia and is considered an opportunistic pathogen, meaning it primarily affects individuals with weakened immune systems. Unlike some other infectious diseases, Legionella does not spread directly from person to person.

Helicobacter pylori is a bacterium that is known to cause duodenal ulcers and chronic gastritis. Bismuth salts are able to inhibit the growth of H. pylori. The organism also expresses urease, which helps raise the pH locally and protects it from the acidity of the stomach.
