Group B Streptococcus Testing

Group B Streptococcus (GBS) Testing is a medical procedure that screens for the presence of the GBS bacteria in a pregnant woman’s body. It is important for this test to be performed because a GBS infection during pregnancy can cause neonatal meningitis, sepsis, or even death (Albouy-Llaty, Nadeau, Descombes, Pierre & Migeot, 2012). According to Mercer, Ramsey & Sibai (1995), 18 to 32 percent of congenital infections are caused by neonatal sepsis and can be a major cause of mortality and morbidity where 1.3 to 3 per 1000 neonates are affected by the early onset of Group B streptococcal sepsis.

Pathophysiology of Rheumatic Fever

Introduction
Rheumatic Fever (RF) is the type of inflammatory disease that can develop due to untreated or inadequately treated throat infection (scarlet fever or strep throat) caused by a type of bacteria known as streptococcus (Carapetis, McDonald & Wilson, 2005). This paper is going to cover pathophysiology of the Rheumatic Fever. It will begin with the symptoms associated with RF. A description of mechanisms or processes that take place in a person infected with RF will be described. This will be followed by a discussion of the causes of RF. There is a section dedicated to the pathophysiology of RF ...

Pathogenic and Non-pathogenic Organisms

Similarities in both organisms include the fact that both organisms are non-sporulating. Although, not the only metabolite, Salmonella enterica can produce lactate as one of its metabolite while Lactococcus lactis produces lactate. Both organisms are anaerobes, feeding by fermenting substrates (PHAC, 2010). Salmonella enterica ferments glucose while Lactococcus lactis ferments milk.
Salmonella enterica is different from Lactococcus enterica in several ways. From gram staining, Salmonella enterica is a gram-positive organism while Lactococcus lactis is a gram-negative organism. At the level of feeding, Salmonella enterica feeds on a wide range of carbohydrates (PHAC, 2010). It is a heterofermentative organism whereas Lactococcus lactis is a ...

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 ...

Industrial microbiology has helped greatly in the discovery and development of substances that we use in our day to day life. It applies scientific and bioengineering techniques to processes and materials. Microorganisms produce valuable products of industrial microbiology.(Law 15) They include; Antibiotics, fermentation beverages, enzymes for amino acids synthesis, dairy products, and recovery of minerals from low grade ores, waste and waste water management, Biodegradation of xenobiotics, synthesis of chemotherapy drugs, just to name but a few. It’s a field that requires people to research on existing problems find or discover new products, get ways of producing and commercializing ...

Article #1:

The article focussed on the breeding behaviours of emperor penguins that are recently discovered with the help of satellites. Mostly it is believed that penguins lay their eggs on sea ice that is fast and stable and that remains intact under the chick fledge. Fretwell and co-workers conducted this study on forty-six colonies emperor penguins. The recent observation revealed that few colonies of emperor penguins breed on ice-shelves instead of sea ice. Due to rapid climate changes and the incidence of ice melting the penguin population has declined and very close to extinction. It is a big concern that ...

A. Gauge the size of various biological components and organisms. The Virtual Microscope (copy and paste this address into a new browser window: http://learn.genetics.utah.edu/content/cells/scale/ ) can be used to make these observations. Estimate the size (length and width in microns) of
An E.Coli cell is around 0.5µm in width and around 2µm in length. A mitochondrion is around 0.5µm in width and approximately 10µm in length. A Red blood cell is around 5.5µm in width and 7.5µm in length. A virus is approximately 0.25µm in width and ...

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 but they also ...

Why Pneumococcal Infections is a Global Health Problem

Pneumococcal infections are mainly caused by streptococcus pneumoniae also known as pneumococcus. Serious pneumococcal infections are a major global health problem. By the year 2010, the World Health Organization estimates that more than 1.6 million people – including more than 800,000 children under the age of 5 years – die every year from pneumococcal infections (Georgiev, 2009). Nearly all of these infections and deaths occur in the world’s poorest countries. These include Sub-Saharan African countries, Latin America, South Asia, some parts of Europe and Australia. In Latin America, epidemiological studies show that infants younger than 6 months have a higher risk ...

INTRODUCTION

General overview

Preparation of yoghurt takes place through milk fermentation process with various cultures of bacteria comprising of streptococcus subspecies mixed with lactobacillus delbrueckii subspecies and thermophiles (Barbano, 2009). Basically, yoghurt comes in two types: distilled and set (Augustin et al., 2003). The author further explains there is a difference in the main procedure through which these yogurts are manufactured. In the set yoghurt (inclusive of fruit on the bottom), the formation takes place in retail pots as the fermentation of the lactic acid bacteria proceeds into lactic acid generating a structure of continuous gel in the container of the consumer. ...
