TAQ1 Definition of Pathogen and research into the main features of bacteria‚ protozoa‚ fungi and viruses. Pathogens‚ or infectious agents‚ are microorganisms that cause disease or illness to their host. There are divided into four groups; bacteria‚ protozoa‚ fungi and viruses. The term pathogen most often describes an organism that disrupts the normal physiology of a plant or animal. In identifying a pathogen it is important to determine the properties that ‘contribute to its infectious

“DISCUSS THE STRATEGIES THAT ARE USED BY BACTERIAL PATHOGENS TO EVADE HOST ANTIBACTERIAL PEPTIDES AND PHAGOCYTES” The mammalian immune system has two major components; the innate and the adaptive immune system. The innate system is usually the first line of defence and it acts as a strong roadblock to invading bacterial pathogens through direct mechanisms such as inflammation‚ phagocytosis‚ complement system activation‚ antibacterial peptides and indirectly by activating adaptive response through

One of the most common bacteria that infect the wild and cultured Tilapia is Aeromonas sobria. Aeromonas sobria is water borne pathogen that are common in almost all aquatic environments including fresh‚ brackish and marine water. They cause fin rot or skin rot disease and may lead to heavy mortality in cultured tilapia (El-Sayed‚ 2006). Aeromonas sobria veronii also causes a similar

Infection Control What causes people to get sick? How is disease spread from one person to another person? What can be done to stop the spread of infection and disease? As a health care worker‚ it is important to know the answers to these questions. When you understand what causes infection‚ you can learn how to prevent it. Infection control is a set of practices and procedures that will help to prevent the transmission of disease within a health care facility. Infectious and Communicable Diseases

the causative agent can be found in blood. Vector-borne diseases include West Nile virus and malaria. Many blood-borne diseases can also be transmitted by other means‚ including high risk sexual behaviour. Since it is difficult to determine what pathogens any given blood contains‚ and some blood-borne diseases are lethal‚ standard medical practice regards all blood (and any body fluid) as potentially infective. Blood and Body Fluid precautions are a type of infection control practice that seeks to
