Which organism causes polio?
poliovirus the causative agent of poliomylitis. it consists of three serotypes named type 1,2,3 and belong to enteroviruses group.inf. occurs through nasopharynx.
What gram negative organisms have capsules?
Several Gram-negative organisms possess capsules, which serve as a protective layer. Notable examples include Escherichia coli (certain serotypes, such as K1), Klebsiella pneumoniae, Neisseria meningitidis, and Pseudomonas aeruginosa. These capsules enhance virulence by aiding in evasion of the host's immune response and promoting adherence to surfaces.
Is Escherichia coli encapsulated?
Some serotypes (species) of E. coli form capsules. So, not all E. coli form capsules but some do.
Why is the capsulated form of Streptococcus peneumoniae more virulent than the noncapulated form?
I believe all forms of strep pneumoniae are encapsulated. The polysaccharide capsule dictates the virulence factor and there are many different serotypes. Each type has a different prevalence and level of virulence, as well as different resistance to drugs. If I had to answer your question (for homework?) I would say that encapsulation provides superior resistance to environmental threats, giving the organism a better chance of survival when not in optimal conditions.
Why is vaccine developed for influenza but not for rhinovirus?
Because the rhinovirus (which is one virus that causes the common cold) mutates and changes its structure extremely frequently as do the other viruses that cause the common cold, such as Coronaviruses, and any of the others of hundreds of viruses that cause colds. While influenza strains also mutate, it is not as quickly as cold viruses that almost constantly are mutating, resulting in several dozen active viruses in any one locality. In addition, influenza has proven reasonably easy to grow in labs for study and for vaccine production, while cultivating rhinoviruses has proven very difficult.
What if you are positive for 13 hpv 16 18 31 33 35 39?
These serotypes are high risk for getting cancer.
Can a person infected with dengue be a lifetime carrier?
No, a person infected with dengue cannot be a lifetime carrier of the virus. While dengue can cause severe illness and complications during an infection, the immune system typically clears the virus from the body. However, infection with one of the four dengue virus serotypes provides lifelong immunity to that specific serotype, but not to the others, meaning a person can still be infected again by different serotypes.
What is the difference between polio type 1 2 and 3?
In poliomyelitis, polio viruses with 3 different serotypes have been identified. These are classified by their capsid protein differences in PV1, PV2, and PV3.
What is salmonella arizonae?
Types of salmonella bacteria can be distinguished from one another based on the different arrangement of structures on the surface of the cell - referred to as serological types or "serotypes". Examples include Salmonella Enteritidis or Salmonella Typhimurium. Often these serotypes are given names according to the place where they were first discovered, like Salmonella Saintpaul. It is possible this is how Arizonae got its name.Salmonella arizonae is a type of Salmonella bacteria that has been associated with reptiles. There have been illnesses in people who have kept reptiles as pets.
How long are you immune to dengue once infection 1st time is cleared?
After a primary dengue infection, immunity typically lasts for several months to a few years, but it is not lifelong. While the body develops antibodies that provide some protection against the same serotype of the virus, this immunity does not extend to other dengue serotypes. Subsequent infections with different serotypes can lead to more severe forms of the disease, such as dengue hemorrhagic fever. Therefore, it is important to remain cautious even after recovering from a primary infection.
How many times a person can have dengue?
A person can contract dengue fever multiple times, as there are four distinct serotypes of the dengue virus (DEN-1, DEN-2, DEN-3, and DEN-4). Infection with one serotype typically provides lifelong immunity to that specific type, but not to the others. Subsequent infections with different serotypes can occur and may increase the risk of severe dengue. Therefore, it's possible to have dengue fever up to four times in a lifetime, once for each serotype.
What is the difference between prevnar 7 and prevnar 13?
Prevnar 7 and Prevnar 13 are both pneumococcal vaccines, but they protect against different strains of the Streptococcus pneumoniae bacteria. Prevnar 7 covers seven serotypes, while Prevnar 13 covers 13 serotypes, including all those in Prevnar 7 plus six additional ones. This broader coverage in Prevnar 13 offers enhanced protection against pneumococcal diseases such as pneumonia, meningitis, and otitis media in children and adults. As a result, Prevnar 13 is often recommended over Prevnar 7 for updated immunization schedules.
Which organism causes polio?
poliovirus the causative agent of poliomylitis. it consists of three serotypes named type 1,2,3 and belong to enteroviruses group.inf. occurs through nasopharynx.
What type of pathogen is dengue?
Dengue is an acute viral disease caused by any of the four dengue virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4). The principal mosquito vector is Aedes aegypti. This disease is sometimes called "bone break" fever because of the tremendous chills and shaking the patient has.
What gram negative organisms have capsules?
Several Gram-negative organisms possess capsules, which serve as a protective layer. Notable examples include Escherichia coli (certain serotypes, such as K1), Klebsiella pneumoniae, Neisseria meningitidis, and Pseudomonas aeruginosa. These capsules enhance virulence by aiding in evasion of the host's immune response and promoting adherence to surfaces.
Why there is no vaccination for cold but there is vaccination for the flu?
The Common Cold (Rhinovirus) is different for each person, there is no vaccination becasue there are either to little to no cross protection between at leaset 99 serotypes. Though from what I understand a vacine is being deleloped but it's a slow process As for the flu it's a more deadly virus that changes frequently and so having the vaccination protects you mroe aginst it .
Does every type of polio causes to paralysis?
Not every type of polio causes paralysis. The poliovirus has three serotypes: poliovirus type 1, type 2, and type 3. While the majority of infections are asymptomatic, about 1 in 200 infections can lead to paralysis. Most cases are mild or asymptomatic, but in some instances, the virus can affect the nervous system, resulting in paralysis.
