Introduction

Milk and milk products are widely used as food items universally. Whole milk is very rich in nutrients. This fact explains why young ones of lactating animals are able to survive exclusively on milk for some period of time. In addition to being nutritious, milk secreted into the udder of a healthy cow is usually sterile (Jay, Golden, Jay-Loessner-Golden, and Loessner, 2005). Unlike other food substances, milk has no native flora. However, it is important to note that once in the udder, the milk may not be necessarily free from bacteria especially if the cow is infected with a Continue reading...

What chemicals do Nitrosococcus oceani and Nitrosopumilus maritimus consume from their ocean environment?  How does the abundance of these chemicals influence their success and abundance?  What is the relationship between nutrient availability and natural selection, in general?
Nitrosococcus oceani and Nitrosopumilus maritimus are examples of single celled organisms which are part of the kingdom Archaea. They are totally separated from the bacteria and other organisms (Stewart, n.d.). They are very important for some of the natural processes in the environment especially for the nitrogen and methane cycle. They are also a major part of the biological and biomass processes Continue reading...

The technological advancement has introduced numerous achievements in the field of biotechnology. Microbial transformation or biotransformation is the phenomenon where living organisms are used in modifying materials that are not frequently used for growth (Donova and Egorova). Apart from animal cells, plant tissues and enzymes, microbial transformation is associated with the reactions under biotransformation. A substance can be transformed into another product through microbial action on the substrate. Studies reported that the utilization of biotechnology in the formulation of steroids was introduced in the year 1952. Murray and Peterson developed 1 lα-hydroxylation using Rhizopus and utilized it effectively Continue reading...

In adults above the age of 45, cardiovascular diseases are common. There are several risks factors associated with cardiovascular disease such as hypertension, low density lipoprotein (LDL), gender (male), smoking, and low socioeconomic status. Few studies have suggested the link between atherosclerotic diseases and infection. Many researchers have suggested the link between several viruses and bacteria and the etiology of cardiovascular diseases. In transient bacteremia, dental procedures and periodontitis are considered as potential factors. In such cases, full mouth debridement resulted in Schwatzman reactions. In patient with periodontitis, gentle mastication can release bacterial endotoxins in the blood stream. During Continue reading...

Essay 1. Anthrax

Anthrax is a lethal disease which could affect most of the animals including humans. The major cause of anthrax is the bacterium Bacillus anthracis. It is a large gram-positive bacterium which is non-motile and could form spores (Rao et al, 2010). The bacterium lives in the soil in a spore from which could provide them protection and survive for more than decades. While in the spore from, they produces the toxins that could infect animals and humans into three major factors. The three major factors that could provide the virulence of the Bacillus anthracis which are lethal toxin, edema Continue reading...

Introduction
The choice of antimicrobial agent has a principal meaning for effective treatment of the infections which can be evoked by different causative pathogens. This paper reviews categories of antimicrobial agents, describes the differences between viral and bacterial infections and considers the importance of determining viral or bacterial etiology of the disease for choosing a specific antimicrobial agent.

Summary

All antimicrobials are basically divided into four broad categories: antibacterial, antiviral, antifungal and antiparasitic agents. This classification is based on the type\spectrum of microorganisms these drugs are targeted at, the way of their action and their chemical structure and pharmacokinetics ( Continue reading...

Without water there would be no life. Without life, there would be no humans or human civilization. There would be no cities. In fact, Las Vegas grew out of the desert because of water. Man’s conquest of and control of water allowed the city of Las Vegas to not only exist, but to thrive. It is a large city in the middle of the desert. This begs the question of how Las Vegas, or the rest of Southern Nevada gets its water. This paper explores water in southern Nevada, the sources, how the water is treated, the state Continue reading...

Wastewaters involve a large spectrum of different organic compounds depending on the scheme of production. The activated sludge process is the preferred treatment scheme for effective removal of organic matter through the aeration of wastewater mixed with reused biological sludge full of living microorganisms . The biological solids then separate from the treated wastewater in a clarifier and return to the aeration process. The microorganisms mix thoroughly with the incoming organic material, wherein they grow and reproduce using the organic material as food. Once flocculated, the living organisms readily settle in the secondary clarifiers. The waste water flows continuously into Continue reading...
