INFECTION CONTROL Pathogen- Infectious agent Colonization- If microorganism is present or invades host‚ grows and/or multiplies but does not cause infection. Communicable disease- if infectious disease can be transmitted from one person to another. -Symptomatic-if pathogens multiply and cause clinical signs/symptoms. -Asymptomatic- if no s/s are present *CHAIN OF INFECTION: 1. An infectious agent or pathogen 2. A reservoir or source for pathogen growth 3. A portal of exit from the

monsoon the occurrence of variation of different species were high. The microorganisms isolated from the soil were of staphylococcus strain and were gram positive‚ aerobic‚ coccus shaped bacteria. The fungal species were also identified‚ of which Aspergillus and Penicillium were dominant‚ followed by mucur‚ as sub dominant .This project aims to find out the water and soil quality of River and as it is flowing through an industrial area‚ to find out if it is getting affected by the Industrial pollutants

An investigation into the effects of glyphosate on a yellow meadow ants ability to chose a food source Abstract: Yellow meadow ants play a vital role in our ecosystem and this experiment looks at how glyphosate alters their decision making when choosing a food source. To analyse the ants choice making I used a choice chamber with one side containing banana without glyphosate and one side with the herbicide. I hypothesised that there would be more ants moving to the side without the glyphosate because

Riboflavin‚ also known as vitamin B2 is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN‚ and is therefore required by all flavoproteins. As such‚ vitamin B2 is required for a wide variety of cellular processes. It plays a key role in energy metabolism‚ and for the metabolism of fats‚ ketone bodies‚ carbohydrates‚ and proteins. It is also used as an orange-red food colour additive‚ designated in

Some of the most common indoor species of molds are Penicillium‚ Aspergillus‚ Cladosporium and Alternaria. Some building materials act as catalysts for the growth of black molds. These include paper and paper products‚ wood and wood products‚ cardboard‚ ceiling tiles‚ and wet cellulose materials. Other household stuff that

Mold can grow in many different places. There are four different types of mold. Mold is impossible to see with the naked eye without a microscope. There is a type of mold called “Zygomycota”. Zygomycota grows mainly of fruit. Zygomycota is the type of mold that I will be working with in my science fair project. Zygomycota is one of the types of mold that are invisible to the naked eye in the early stages of development. Zygomycota grows on high sugar sources. So mostly on fruit and sugary

hypothesis due to the correlation between amylase activity and the starch. This is experiment displayed how efficiently temperature affected the shape of the enzyme‚ thus affecting the enzyme activity so It could function properly. Methods: Aspergillus oryzae known as fungal amylase and Bacillus licheniform also known as bacterial amylase were the two enzymes that were used to examine the different temperatures in order to find the optimal temperature to break down the starch. During the preparation

Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures. Maydelis Perez PI 4593042 Florida International University BSC 1010L‚ section UO9‚ March 6‚ 2013 Abstract Enzymes are very specific protein because they contain one active site on their surface that enable the substrate to bind to the enzyme and form the enzyme substrate complex and then release

INTRODUCTION Onychomycosis is defined as a fungal infection of the nail that expands slowly and if left untreated leads to complete destruction of the nail plate‚it can be dermatophytic (99%) and/or nondermatophytic (1%) (Including yeasts) infections of the nail plate. (1) The dermatophytes Trichophyton rubrum and Trichophyton mentagrophytes are the most common causative pathogens responsible for up to 90% of all cases.(1) Onychomycosis represents about 30% of all dermatophyte
