Vaccines are for preventing infections. Infections are pathogenic (caused by germs). Vaccines help your body prepare to fight specific pathogens, e.g., bacteria and viruses.
kills any pathogenic bacteria in your body
It is a vaccine which protects against the pathogenic bacteria called Corynebacterium diphtheriae. This bacteria causes an upper respiratory tract illness called Diphtheria.
Frederick Griffiths observed natural transformation for the first time, while he was searching for the pneumonia vaccine. He discovered that mixing a heat killed pathogenic strain of bacteria with a living nonpathogenic strain converted some cells into the pathogenic form.

No. There is a vaccine for the flu and H1N1, but not for the common cold. But all you need for the common cold is TLC and a little bit of orange-flavored Delsum. :)
Attenuated simply means "weakened". An attenuated flu vaccine refers to vaccines made with live viruses (so you get a good immune response), but they have been weakened chemically so that they are unable to give you the flu. There are two types of flu vaccines available in the US. What is called inactivated, inactive or "dead" vaccine and what is called "live", weakened/attenuated vaccine. The injectable vaccines (intradermal and intramuscular) are made with "dead" viruses and the nasal spray is made with "live" attenuated viruses.
Killed vaccines: These are preparations of the normal (wild type) infectious, pathogenic virus that has been rendered non-pathogenic, usually by chemical treatment such as with formalin that cross-links viral proteins.Attenuated vaccines: These are live virus particles that grow in the vaccine recipient but do not cause disease because the vaccine virus has been altered (mutated) to a non-pathogenic form; for example, its tropism has been altered so that it no longer grows at a site that can cause disease.Sub-unit vaccines: These are purified components of the virus, such as a surface antigen.DNA vaccines: These are usually harmless viruses into which a gene for a (supposedly) protective antigen has been spliced. The protective antigen is then made in the vaccine recipient to elicit an immune response
No, not all pathogenic bacteria are gram-negative. Pathogenic bacteria can be either gram-negative or gram-positive, depending on their cell wall structure. Some common gram-negative pathogenic bacteria include Escherichia coli, Pseudomonas aeruginosa, and Neisseria meningitidis, while some gram-positive pathogenic bacteria include Staphylococcus aureus, Streptococcus pneumoniae, and Enterococcus faecalis.
Yes, their are some Euglena that are pathogenic. Many are pathogenic, although some are not.
Pathogenic.
Pathogenic bacteria are bacteria that cause bacterial infections to humans. Tuberculosis is one of the common diseases that are caused by a bacteria called Mycobacterium tuberculosis. Other common infections caused by Pathogenic bacteria are typhoid fever, diphtheria, tetanus, and syphilis.
