  • Surviving Clean Water

    unsafe to drink. It doesn't matter if you get water from a fast moving, crystal clear stream or a lake filled with algae. All of the water is dirty and filled with nasty viruses, protozoa, bacteria and in some cases, chemical…

  • Pruritus Vulvae: A Case Study

    Physiological vaginal discharge does not need medical intervention. However discharge associated with increased quantity, pruritus, and foul smell, with changes in its colour or with blood seeks medical treatment (Panda et al, 2013).There are different types of pathogens causing vaginal discharge and their identification is challenging. Vaginitis caused by bacteria, fungi or protozoa can be associated with altered vaginal discharge and odor (Kataria et al, 2015). Vulval irritation, or pruritus…

  • Six Major Types Of Microorganisms And Disease

    are bacteria, archaea, fungi, protozoa, algae, and viruses. This essay aims to analyse micro-organisms and disease. First the key features of the main categories of micro-organisms and the roles of commensals, and pathogens will be explained respectively. Then mode of transmission, portals of entries and exits of microbes are explained. How our body defence mechanisms prevent from the infections will be discussed after the logical sequence of events that occur from the entry of a micro-organism…

  • Livestock Production And Climate Change

    proper ratio of microbes are present in the rumen and finally the optimum level of nutrients in the feed must be present. In the rumen fermentation, the microbes (bacteria, 40-50%; protozoa, 40-50% and fungi, 3-4% of total microbial biomass) act synergistically to degrade feed, while archaea and bacteriophages might help indirectly in the fermentation of feed (Kamra, 2005). This synergism might be due to a distinctly different mode of attack on fibrous feeds, therefore these microbial groups do…

  • NANDA International: The Risks Of Infection

    In terms of nursing diagnosis, the risk of infection is defined as "the state in which an individual is at risk to be invaded by an opportunistic or pathogenic agent (virus, fungus, bacteria, protozoa, or other parasite) from endogenous or exogenous sources" and was approved by NANDA in 1986. The risk of infection could be from any kind of pathogen and the level of infection might also very form patient to patient, based on the type of infection. According to the nursing diagnosis, elevated risk…

  • Eukaryotic Cells

    that has been engulfed by a larger cell, but wasn’t destroyed as a mutually beneficial relationship was formed. It is widely accepted that some if not all modern eukaryotic cells originated in this form. This theory also explains why the mitochondria contains its own ribosomes (Bolsover, S., Hyams, J., Jones, S., Shephard, E. and White, H. 1997) and circular genome very similar to that of a bacterial genome (Allison, L. 2007) also why the mouse mitochondrial DNA was shown as more closely related…

  • AP Biology Summer Assignment: Survival Of The Sickest

    Justin Dubler August 31, 2015 Mrs. Werle Period #1-2 AP Biology Summer Assignment Survival of the Sickest Big Idea 1: The process of evolution drives the diversity and unit of life. Passage 1: “Our genetic makeup has been adapting in response to where we live and what the weather’s like. The food we eat has evolved to cope with the organisms that eat it, and we’ve evolved to cope with that. We’ve looked at the way we’ve evolved to resist or manage the threat posed by specific infectious…

  • Population Growth In Paramecium

    Paramecia, unicellular cilliated protozoa, usually are ovoid and elongated. They widespread in brackish environments and freshwater. Length of the species are various ranging from 50 micrometers to 330 micrometers. They feed on yeasts, algae, and small protozoa which are captured by them through phagocytosis, devouring a particle by “wrapping pseudopodia around it and packaging it within a food vacuole” (Campbell and Reece 2011). They also serve as the models for the study of basic biological…

  • Life Cycle Of Naegleria Fowleri

    Naegleria Fowleri Parasites are living organisms that survive by living and feeding off another organism. There are millions of different kinds of parasites, but, this paper will discuss the biology and life-cycle of the parasitic organism, Naegleria Fowleri. It will also go into the dangerous health effects on the human body caused by an infection of the parasite. What is Naegleria Fowleri? Naegleria Fowleri, more commonly known as the “brain-eating amoeba,” are “microscopic, single-celled…

  • How Does Global Warming Affect The Human Population

    leads to rise in vector borne diseases. Mosquitoes, ticks and fleas are hosts to many viruses such as bacteria and protozoa. 1.3 FOOD SAFETY: ASIYEH ATTAR The impact of climate change on production, distribution and trade of food is enormous. Acute illness caused by foodborne viruses are an emerging threat. Common illness such as Salmonella and Toxoplasma gondii and others make up for an estimate of 48 million cases of foodborne illness per year. (, 2017) Furthermore, transportation of…
