Explanation
Some bacteria have a morphological characteristic called "chains" or "clusters", where they form long chains or clusters of cells. This characteristic is commonly seen in enterococci, which are a type of bacteria that are commonly found in the intestines of humans and animals. The other options mentioned in the question, such as the capsule, gram-positive cell wall, and spores, are not specific to enterococci and can be found in other types of bacteria as well. Therefore, the correct answer is that enterococci have a characteristic of moving in small chains.

The correct answer is "แแแ แแกแแแก แคแแ แแแแขแแแ" (Aggregatibacter fermentans) because it is the only option that is related to the pathogenicity of enterococci. Enterococci are a type of bacteria that can cause various infections in humans, and Aggregatibacter fermentans is a specific species that has been associated with periodontal diseases. The other options, "แแแขแแแแแ" (Catalase), "แแแคแกแฃแแ" (Capsule), and "แแ แแ แแแแแฃแแ แขแแฅแกแแแ" (Endotoxin), do not directly relate to enterococcal pathogenicity.

Endocarditis is the correct answer because it is a condition characterized by inflammation of the inner lining of the heart, usually caused by bacteria, including enterococci. Enterococci are a type of bacteria commonly found in the intestines and can cause infections in various parts of the body, including the heart. Therefore, it is the most likely infection that enterococci would cause.

Explanation
The correct answer suggests that enterococci differentiate from streptococci based on their resistance to high salt concentrations. Enterococci are able to grow and survive in high salt environments, such as the intestines, while streptococci are not. This characteristic is used to distinguish between the two groups of bacteria.

Explanation
Hyaluronidase is an enzyme that breaks down hyaluronic acid, a substance found in the extracellular matrix of connective tissues. By breaking down hyaluronic acid, hyaluronidase facilitates the spread of other substances, such as drugs or toxins, through the tissues. Therefore, hyaluronidase is responsible for increasing the permeability of the extracellular matrix and enhancing the diffusion of molecules within the tissues.

Neiraminidaza is the enzyme that is responsible for cleaving the glycosidic linkages of neuraminic acid residues in glycoproteins and glycolipids. This enzyme is important in the invasion process of meningococci, as it allows the bacteria to detach from the host cell surface and spread throughout the body. Therefore, the correct answer is Neiraminidaza.

Explanation
The correct answer is "แแแคแกแฃแแแก แแแแแกแแฅแแ แแแฃแแ" because N. meningitidis has a polysaccharide capsule that helps protect it from the immune system and is a major virulence factor for the bacterium. The capsule helps the bacteria evade phagocytosis and contributes to its ability to cause invasive disease.

Explanation
The correct answer is "แแแคแกแฃแแ แแแแแกแแฅแแ แแแฃแแ แแแขแแแแแ" (capsular polysaccharide antigen). This is the factor that protects meningococci from phagocytosis. Capsular polysaccharides are a major virulence factor of meningococci, as they prevent the bacteria from being recognized and engulfed by immune cells, allowing them to survive and cause infection.

The correct answer is "แฃแฏแ แแแแก แแแแแแก แแแแแแแแแกแแฅแแ แแแ" which translates to "Endotoxic shock is caused by the lipopolysaccharide of the cell wall". This answer explains that endotoxic shock is caused by the lipopolysaccharide component of the cell wall of certain bacteria, which triggers an excessive immune response leading to shock. The other options mentioned (hyaluronidase, extracellular antigen, and capsular antigen) are not directly associated with the pathogenesis of endotoxic shock.

Endotoxins are toxins that are released from the cell wall of certain bacteria when they die or are destroyed. They are not actively secreted by the bacteria, but rather are part of their structure. Endotoxins can cause a variety of harmful effects in the body, including inflammation, fever, and even septic shock. Therefore, the correct answer is endotoxins.

The correct answer is "แแแแแแแแแแชแแคแแแแขแก". This is because meningococcal meningitis is a bacterial infection that affects the meninges, which are the protective membranes surrounding the brain and spinal cord. It is commonly associated with symptoms such as fever, headache, stiff neck, and a characteristic rash. The other options, such as "แฌแแแแ แฅแแ แก" (red measles), "แฐแแแแขแแขแก" (hepatitis), and "แแแกแขแ แแขแก" (gastritis), are not typically associated with meningitis.

Endocarditis is an inflammation of the inner lining of the heart chambers and valves. It is typically caused by a bacterial or fungal infection. The other options listed, such as hepatitis, nephritis, and enteritis, are not associated with clinical forms that would cause meningococci. Therefore, the correct answer is endocarditis.

"แคแแแแแฃแ -แแ แแแฃแ แ" refers to fecal-oral transmission, "แขแ แแแกแแแกแแฃแแ" refers to transmission through blood or bodily fluids, and "แแแแแแแขแแ แฃแแ" refers to transmission through food or water.

The correct answer is "แแแแแแงแแคแ แแแแแแแแ" (Infected humans). This is because the question asks for the source of meningococcal infections, and the correct answer identifies infected humans as the source. The other options (แแฆแ แฆแแแแแแ, แแแแแแงแแคแ แชแฎแแแแแแแ, แแฌแแ แแแ) are unrelated to the transmission of meningococcal infections.

An antiseptic is a substance that is used to kill or inhibit the growth of microorganisms, such as bacteria. In the context of the question, the question is asking what type of antiseptic is used after a meningococcal infection. Meningococcal infection is a bacterial infection caused by the bacteria Neisseria meningitidis. Therefore, it is important to use an antiseptic that is effective against bacteria. The correct answer, "แแงแแ แ แแแขแแแแแ แแแฃแแ" (translated as "oral antiseptic") indicates that the antiseptic is used in the mouth, suggesting that it is effective against the bacteria in the oral cavity.

Sulphanilamides are a class of antibiotics that are commonly used to treat meningococcal infections. They work by inhibiting the growth and reproduction of the bacteria responsible for the infection. Sulphanilamides are bacteriostatic, meaning they prevent the bacteria from multiplying and spreading, allowing the immune system to effectively eliminate the infection.

Explanation
Epithelial cells are the cells that line the surfaces of organs and tissues in the body. They play a crucial role in protecting the underlying tissues, regulating the exchange of substances, and providing a barrier against pathogens. Cytotoxic T cells, which are a type of immune cell, primarily act on epithelial cells. They recognize and destroy infected or abnormal epithelial cells to eliminate pathogens and maintain tissue health. Therefore, the correct answer is "แแแแแแแแแชแแขแแแแ" (on epithelial cells).
