A pathogenic or an infectious disease is caused by an external infectious agent or pathogen such as viruses‚ bacteria‚ parasites and fungi. These pathogens are found in water‚ soil and air and a human body can be infected from drinking‚ eating or touching something infected with germs. Examples of a bacterial pathogenic disease are pneumonia and gonorrhea‚ while viral pathogenic diseases include influenza and measles. An example of a parasitic pathogenic disease is malaria‚ while an example of

Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts.

Pathogens are everywhere. They are in people‚ animals‚ and the environment. Pathogens come in a wide variety. The types are fungal‚ bacterial‚ viral‚ and other parasites. All pathogens can be dangerous‚ but two of them are more dangerous. These two types that more dangerous are fungal and bacterial. While both fungal and bacterial pathogens cause illness‚ they differ in the way they are transmitted‚ the way they are treated‚ and the diseases they cause. First‚ the way fungal and

My idea of a perfect pathogen would be one that can survive and persist long enough to cause infection and to be transmitted to the next host. And this multiplicity of behaviours depends at least on the generation of diverse cell surface structures and phenotypic variants to evade the host immune response. One such strategy to achieve this in bacteria is antigenic variation‚ a strategy also employed by viruses‚ fungi‚ and protozoa‚ which all face similar challenges when infecting a host‚ that is

Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic. What is the scientific name for this process? methicillin-resistant Staphylococcus aureus Why is bacterial resistance a problem? Because they can cause diseases. What has led to an increase in the amount of bacterial resistance? Because the particles

containing the viruses or bacteria that can result to a big breakdown of the business. Viruses‚ bacteria‚ mycoplasma‚ and some forms of parasites are considered microbes. When a microbe contributes to the occurrence of disease‚ it is referred to as a pathogen. Most microbes‚ however‚ do not adversely affect the animal. There is a normal flora of microbes literally covering every external and internal surface of the pig’s body. These normal microbes occur on the skin‚ in the ears‚ mouth‚ stomach‚ intestine
