Essays on Microorganisms

There exists about 300,000 plant species on earth, and every individual plant hosts one or more endophytes. However, it is just a few of these plants that have been researched relative to their endophytic biology. Hence, the chance for isolation of new, as well as, interesting endophytic bacteria in plants are important. Endophytic bacteria can be referred to as bacteria that can be isolated from tissues of a surface-disinfected plant or bacteria extracted from inside of a plant, which cause no visible negative effects to the plant. Almost every plant is populated by varied bacteria referred to as

Introduction:

Clean non-polluted water is a major basic requirement for all the living things. Nowadays, its availability becomes a major problem in the ecosystem. This problem is expected to increase in the future due to population growth and industrialization processes. The processes discharge of domestic, industrial and agricultural wastes contribute largely to the contamination of existing natural waters in the environment. Therefore, at the present moment, it is important that the pathogens and pollutants are completely removed from the waste water to cater for the needs of domestic use, industrial use, and irrigation purposes. This paper discusses two processes of

Soils are an effective medium of treatment for septic system effluent because they contain complex biological communities. A tablespoon of soil may contain over a million of microscopic organisms including protozoa, molds, fungi, bacteria and other creatures. The microorganisms and bacteria in the soil purify the water before it reaches the underground water. The septic effluent must pass through the soil gradually enough to provide adequate contact with microorganisms. One of the major components in wastewater effluent is nitrogen which exists in different forms. These forms include nitrates (NO3), ammonia (NH3), and nitrites (NO2). Nitrates are essential plant nutrients,

Introduction

Most of the microorganisms naturally present in the human body are harmless commensals. However, there also exists other disease causing microorganisms known as pathogens and the mechanism by which they cause disease is known as pathogenesis. These pathogens persist or multiply within the host causing infection. Some pathogens like Pseudomonas aeruginosa are considered as opportunistic pathogens that cause disease only in patients with compromised immunity and only under certain conditions. The infectious diseases may be treated with antibiotic drugs. However, it is important to know the different types of pathogens and the virulence factors by which they cause disease

Introduction

Bacterial meningitis is an infection that affects the meninges, the cerebrospinal fluid and the spinal cord that causes death and disability in a number of people worldwide. This is a highly contagious airborne disease that is spread through the transmission of three organisms present in the respiratory secretions: Neisseria meningitides, Haemophilus influenzae, and Streptococcus pneumoniae. The onset or origins of the disease varies among different age groups and geographic locations. According to estimates, 200,000 people die annually of meningitis. Case fatality rates vary with age at time of illness and also depend on the particular bacterial strain causing

It is widely accepted that a sufficient food and water consumption is an integral part of living and health promotion. Food safety and quality are therefore considered to be a major concern for food manufacturers, policy makers and general public. Although there is a significant progress in advisory labelling practice, undeclared allergens can sometimes be added into food as a result of a manufacturing process. Allergens can be defined as a substance capable of triggering immediate hypersensitivity (AAAAI, 2014). Food Standards Agency (FSA) (2014) has calculated that each year approximately 10 people die from food-induced anaphylaxis. Poorly controlled production

Canine Micro Biomes Affected by their Diet

Canines Micro Biomes Affected by their Diet
Abstract
Dogs and other cats alike suffer from similar maladies faced by humans. The similarity in the maladies between the two groups of organisms stems from the ability to suffer infections from microbiomes of the gut. However, most of the research and knowledge on canine microbiome is not comprehensive to enable the deduction of accurate and precise conclusions. Recently, the molecular studies conducted on the cat family indicated that there are complex microbiomes in the gastrointestinal tract of then organism. The family of microbiomes includes archaeal, fungal, bacterial, and viral groups that

Microbiology is the study of microorganisms. Microorganisms are those organisms that are less than a millimeter in size and require the help of a microscope to view them. Microorganisms can be unicellular or multicellular but have very simple cell structure, unlike the highly developed, complex organisms such as larger animals and humans. Microorganisms are classified based on criteria such as their cell structure, pattern of growth, nutrition, reproduction method, etc. However, microbial classification is a challenging task due to the dual nature of some microorganisms that exhibit both animal and plant like characteristics. Some microorganisms are photosynthetic like plants

Abstract

Solid waste and wastewater are primary sources of pollution from food processing industries. The wastewaters usually contain high suspended solids, organic starch and sugars that may contain toxic substances to the environment. Solid wastes come from organic materials while the mechanical preparation processes need biological treatment before releases into the environment. When untreated, they find their way into other water plants like lakes and streams. Since they have higher nutrient content, they result of eutrophication of the water systems hence causing algal growth. It, therefore, compromises the stability of the aquatic ecosystems as the water quality is changed. It

Use of Restriction Enzymes in Pharmaceuticals
Restriction enzyme, which is also referred to as restriction endonuclease, is a class of enzyme that is helpful in cutting DNA at restriction sites. Restriction sites are particular recognition nucleotide sequences on double stranded DNA having the length of 4-5 base pairs. Restriction enzymes are also known deoxyribonucleases (DNases). Presently, there are four different types of restriction enzymes:
- Type I enzymes that are “classical” in nature, e.g. EcoKI, EcoBI, and EcoR124;
- Type II enzymes that are “orthodox” in nature, e.g. EcoRI, HindIII, EcoRV;
- Type III enzymes having more than

Dissolved Oxygen

INTRODUCTION
Dissolved oxygen is a useful parameter used to determine the level of effluent in waste water treatment. Living organisms in water bodies require oxygen to break down organic matter. These organisms consume the dissolved oxygen in water and give out carbon dioxide. Oxygen does not readily dissolve in water and gets depleted quickly by increased micro-organism activity. To maintain optimal oxygen levels in a water body, the oxygen replenishing rate from the air should be equal to dissolved oxygen use by micro-organism in the water. A curve drawn to represent dissolved oxygen levels down a stream from a

Surgical site infections (SSI) are the typical type of infections that occur in a wound caused by invasive surgical process. This type of infections is the prevalent causes of healthcare-associated infections. Most patients who undergo a surgical procedure always fall victim of surgical site infections. In minor cases, these infections do occur after the patient is discharged from hospital. It is of great significance to note that, surgical site infections can range from a normal trivial wound discharge without any apparent complication to an adversely complicated condition. This type of infection is related to morbidity, a considerable statistic of

Introduction

Ciproflaxins (or simply Cipro) are a known second-generation of fluoroquinolones. Fluoroquilones, or more generally quinolones, are known as potent chemical agents against Gram-negative bacteria, widely used as a treatment of bacterial infections (Ball, 2000). Ciproflaxins have a wider spectrum of in vitro antibacterial activity and are effective in the treatment of many types of infection associated with Gram-negative bacteria, specifically respiratory tract infections. It is also known to treat anthrax in people (Hilts, 2001).
In a livestock and other animals, a drug which is chemically similar to Cipro is commonly used, known as Baytril. The primary target of Cipro

Background and significance of the problem

Salmonella species are a group of Gram-negative enterobacteria associated with human and animal infections. There are two types of Salmonella strains viz. Typhoid Salmonella and non-typhoid Salmonella (NTS). The former causes enteric fever that leads to significant morbidity and mortality, especially in the developing countries. The epidemiology of Salmonella infections vary considerably depending on the species involved. The enteric fever caused by S. typhi and S. paratyphi is severe and life threatening condition whereas NTS infections are self-limiting. Humans serve as the reservoirs for typhoid Salmonella that transmits predominantly through water. On the contrary, NTS strains harbor animals as

Asepsis

Microorganisms are the tiny microscopic structures that cannot be seen with naked eyes. They are present on all the living things and also in the environment. Some of these microorganisms are non pathogenic that is they do not cause any disease. However, many of the microorganisms are pathogenic in nature. The pathogenic microorganisms can cause disease or infections. Absence of these pathogenic microorganisms is known as asepsis.

Importance of asepsis

Asepsis is usually carried out in the laboratory mostly while dealing with microorganisms. The techniques used to carry out asepsis are known as aseptic techniques. If aseptic conditions are not maintained in

1. Components and mechanisms of the respiratory system
The respiratory system is the system that allow humans and animals to breathe. The main function of the system is to provide oxygen to the body through the blood. Breathing involves two main actions: inhaling and exhaling air. Inhalation brings oxygen into the body via the blood and exhalation chases out carbon dioxide.
The respiratory system is composed of different tissues and organs, including the airways, lungs, bloods vessels and muscles connected to each other to assure a proper breathing process (National Heart, Lung and Blood Institute, 2012). The airways include

1. Ecosystems.
(10 pts) Provide a review of the process of succession and trends in biodiversity, productivity, and nutrient cycling.
Ecological succession refers to the process of gradual change of the ecosystems. This is attributed to the fact that habitats do not remain constant and they keep changing over time. Succession is divided into two; there is primary succession and secondary succession. Primary succession refers to changes which occur on an environment that has never been colonized before, for instance, quarrying on land that has never been quarried before. Secondary succession on the other hand involves environmental disturbance on

Introduction

The Polio virus was first identified by Landsteiner and Popper in the year 1908 as an etiological agent for poliomyelitis. The polio virus was the first virus to be grown in cultured cells which was in itself a great breakthrough leading to (1) development of a killed virus and a live attenuated vaccine; (2) physical and chemical characterization of the virion along with its assembly intermediates, and (3) the characterization of the virus life cycle within the infected cell . Poliomyelitis is a highly infectious disease which may be caused through a virus through the invasion of the nervous system.

Of principal concern is the prevention and control of ventilator-associated pneumonia (VAP) by medical practitioners in intensive care units (ICUs). VAP is one of the most frequently reported infections acquired by patients under mechanical ventilation healthcare. Ventilator-associated pneumonia (VAP) persists to be a frequent and potentially deadly complication of ventilator care (Chulay, 2005), often occurring within environments characteristic of the intensive care unit (ICU) that are high-tech and high touch. Patients who are ventilated and intubated present the unique challenge for critical care registered nurses (RNs) to incorporate evidence-informed practices concerning the delivery of high-quality care (Crunden, 2005).

Ventilator-associated pneumonia

Ventilator-Associated Pneumonia
Ventilator-associated pneumonia (VAP), defined as pneumonia that was absent or not developing at intubation, is the second most common hospital acquired infection (Bahrt, 2009, p. 49). It is the most prevalent hospital acquired infection amongst mechanically ventilated patients in critical care units with an estimated 10-20% incidence rate in some hospitals. It affects approximately 28% of patients requiring mechanical ventilation for >48 hours (Button, Culmer, Southard, & Donaldosn, 2005). Patients on mechanical ventilation for >24 hours are 6 to 21 times more likely to acquire VAP than patients not on ventilator support. VAP is the most

Architecture is very significant in people’s life. Hence, every building should be created correctly. The point is that people face buildings every day: we lie in houses created by architectures; we work in offices created by them as well; we shop in malls projected by architectures. However, some architectures do not strive to build correctly. Although, there is no clear cause for it, but there are many cases when “badly built” buildings cause different diseases. Doctors call it sick building syndrome. This research is devoted to the issue of sick buildings and the syndrome they cause. The peculiarity

The natural soil contains lots of microorganisms that are sufficient enough to naturally produce nutrients required for agricultural activities and benefit the plants; moreover, that improves the quality and quantity of the yield produce. In a situation where the soil fertility is deteriorated, natural and organic fertilizer should be added as they provide all the necessary nutrients required by the living microorganisms and the plants (Traina & Laperche, 1999). Artificially developed fertilizers are rich in nutrients that boost the yield quality and quantity but should be controllably used as they might kill all the microorganism transforming the productive soil into

Deforestation is defined as the act of chopping down trees as well as clearing forests without planting others in their place (Debra 1). People cut down trees for different reasons. The increase in population worldwide has escalated cutting down of trees due to the increase in the demand for land for people to build houses to live in and also to obtain land for farming of both subsistence and cash crops, both by individuals and governments. People, particularly those living in rural areas where they cannot access electricity as well as gas, resort to cutting down trees for firewood,

Introduction: Prior to the discovery of penicillin by Alexander Flemming millions of people worldwide succumbed to common infections. The influenza pandemic of 1918-1919 killed nearly 30 million people, which was higher than the population that succumbed to the First World War. Following the discovery of penicillin in 1928, a number of other antimicrobial agents were discovered from natural sources or synthesized in laboratories that led to treatment of many infectious diseases worldwide. It was believed at one point that these magic bullets could be used to target and kill any and all kinds of pathogenic microorganisms. However, soon after

INTRODUCTION

Every year, many lives are usually lost due to the spread of infections in the hospitals. Although all hospitals have infection control procedures and policies, the risk of infections seems to be impossible to completely eliminate. In the course of my clinical nursing experience, I have noted that these infections that are mostly picked up during a patients stay in the hospital mostly ranges from lung infections, urinary tract infections, Methicilin-Resistant Staphylococcus Aureus (MRSA), and blood stream infections among many others (Amos & Waugh,2010). These are commonly known as hospital-acquired infections (HIA). In this paper, I will expound on
