Pathogen

detect streptococci causing bacteria in the back of their throats and other objective was to view pathogen causing diseases under the microscope. Activity 1 – Identification of Human Streptococcal Pathogens Materials 1. Glass microscope slides 2. Bunsen burner 3. Inoculating loop 4. Sharpie pen 5. 2 bacitracin discs 6. Sterile saline tubes 7. Sterile cotton swabs 8. Tongue depressors 9. Gloves 10. 1 blood agar plate/student pair Procedure Divide a blood agr into two sections, one for you and the other for the lab partner. Wash hand thoroughly before proceduring to the getting a throat culture. Depress the tongue with a sterile depressor, donot put it down on the table or touch any surface with it until the procedure is completed. Swab the inside of the throat known as the pharynx with a sterile swab Swab one…

First, good hygiene practice is critical in chicken farms. Due to the high separability of the diseases, keeping the flocks in a generally healthy state is the first action to consider (Gondwe & Wollny, 2007). Second, the possible carriers of the pathogen should be isolated from the healthy flocks. Breeding with a bird from an unknown source should be prohibited as they might be recovered carrier birds. Third, vaccines has been used in many countries for intervention. Inactivated bacterin…

small metal tube, germs can be passed around easily. “When someone actually goes on a plane, they could be sick and they could actually be in this latency period in which they could actually have the disease but not exhibit any symptoms” (Wang). With Raymond’s invention, the air in planes should be pathogen-free but the air is not the only place germs get spread in the plane. “The…

viruses. It is then surprising to note that, in spite of the tenure and the absence of an immune system, the death of plants by disease end up being an exceptional situation. This suggests that the defense mechanisms of plant cells, both those constituent as those induced by the presence of the pathogen, are very effective to stop or counter an infection. In addition, it has been verified that the plants are able to react to external stimuli, as can be the intensity of light, the amount of water…

allows them to quickly evolve into pathogens. Pathogens can exclusively affect animals or evolve into a pathogen that affects humans too (Wolfe, Punuan, Diamond, 2007). Evolution not only influences the changing of humans, but also the variation of disease within the populations. With diverse immunity, evolutionary ecology and origin of…

Pathogen infection leads to response induction as well as a change in antioxidant activity, chlorophyll content, chlorophyll fluorescence parameter and proteome of the host plant. (Swarbrick et al., 2006).Investigation of plant-pathogen interaction shows pathogens aim to overcome host defense responses while plants employ a battery of responses to limit pathogen growth and disease development. Consequently, plant induces defense mechanism which demands a reallocation of energy towards the…

Bifidobacterium bifidum is one of the most commonly probiotic bacterium found in the body of mammals. This popularity of this pathogen is probably due to its digestion aiding abilities. Bifidobacterium bifidum is rod shaped and commonly found in the intestines of mammals, including humans. The pathogen is beneficial to the body and can be found in intestines mainly but also, breast milk and the vaginal area. The amount of Bifidobacterium Bifidum in your system can be increased by taking certain…

Virtually everyone who works in a scientific field will ultimately have to deal, in one way or another, with the production of healthy clean water and the key concepts to cooking food correctly. The importance of keeping our drinking water clean is not stressed enough. There are distributions of harmful components that are put into our waters on a day to day basis (and the distribution that we speak of is nasty pathogens that are commonly found in human/animal bodily waste).The majority of the…

Relationships Pathogens have with Ecological Diversity The effect that pathogens have on the environment due to ecological diversity is great and complicated. The systems of between disease and species can change an ecosystem drastically and shake up the biosphere entirely. In this essay I will discuss how pathogen like those found in Plague inc. can impact biodiversity in our world today, and vice versa. One obvious consequence of deforestation is the loss of habitat for animals. But one…

Foodborne Pathogens In our homes, we have the possibility of eating foods that may be contaminated with a variety of different foodborne pathogens. A foodborne pathogen is any illness resulting from contaminated food due to pathogenic bacteria, viruses, parasites, and natural or chemical toxins. There are many types of foodborne pathogens, growth of pathogens due to improper food preparation, and there are a variety of habits you can change to prevent foodborne illness. First, there are…
