Bacillus

The focus of this lab was to identify an unknown organism based on its characteristics and the results from each of the tests. There will be various of test to choose from in order to identify the unknown organism, which will eliminate numerous possibilities and narrow it down to one. All the fundamental skills that we have learned and practiced in the lab will be used to perform on our unknown such as aseptic technique, microscopic examination, the use of differential media, and determining if…

are a few types of Streptomyces including clavuligerus, cattleya, and griseus. These all work against both gram-positive and gram-negative bacteria. Another type of organism responsible for creating antimicrobial agents is Bacillus subtilis which inhibits wall synthesis and Bacillus polymyxa that disrupts the cell membrane (Harvey,1998). Since there are so many different microorganisms that create antimicrobial agents there will continue to be new species discovered for a long time. Lastly,…

infection enters its second stage after 7-21 days after initial infection, and it is generally asymptomatic. The TB bacilli start reproducing exponentially within the inactivated macrophages, this eventually result in a rapid expansion of the initial TB bacillus,until the macrophages cannot contain the spread anymore and it will bust and spreading necrotic residue and bacilli throughout the surrounding tissue. Other macrophages will also begin to extravasate from peripheral blood, but they are…

Introduction: The effectiveness of Antimicrobial agents against Microorganisms Population of microorganisms or growth are killed and/or inhibited by natural or synthetic chemical antimicrobial controls (Madigan, et al 2012). Antimicrobial agents are grouped according to their efficacy against microorganisms. Bactericidal that kill and bacteriostatic prevent and/or reduce growth (Madigan et al, 2012). Harmful pathogens are targeted with different antimicrobial agents according to their toxicity…

this slide, it is found that the organism present turned out purple, making it gram positive. This is meaningful because gram positive tells us that this organism has a thick peptidoglycan and teichoic acid cell wall. The morphology turned out to be bacillus, meaning that it is rod…

Neonatal sepsis is defined as clinical syndrome in an infant 28 days of life or younger,manifested by systemic signs of infection and isolation of a bacterial pathogen from the bloodstream (Edwards ms and baker cj 2004). Diagnosis and management of sepsis are agreat challenge facing neonatologists in nicus.clinical diagnosi of presentation is difficult due to non specific signs and symptoms . In addition,laboratory diagnosis is time consuming.this matter necessitates the initiation of empirical…

Biotechnology and probiotic GOS (Galacto-oligo-saccharides) INTRODUCTION What are Prebiotics? Prebiotics are commonly defined as non- digestible polysaccharides and oligosaccharides. These prebiotics enhance the growth of beneficial bacteria like lactic acid bacteria in intestinal tract and also exert antagonistic property against some other species like salmonella sp. or E. coli. Some scientist also defined other properties of prebiotics; which includes resistance to gastric activity,…

canopies (Parsons 2003). Sugarcane plants are able to obtain nitrogen via N2-fixation associated with N2-fixing bacteria including rhizobia. In some recent studies, many nitrogen fixing microbes has been found to be associated with sugarcane, such as Bacillus,…

It is conspicuous from various studies that the metal based nanoparticles is found to be an effective antimicrobial agent against several common pathogenic microorganisms.(Nanoparticles and potential apps, Biomedical applications,Antimicrobial activities of silver nanoparticles, Green synthesis, A review on plants extract mediated, Antimicrobial Properties).It is multidisciplinary area where in nanotechnology has led to major developments in health and medicine due to the integration the…

In experiment 2.1, absorbance readings for both heated and unheated corn and tapioca starch were taken. For both starch’s the heated results came to be much higher then the un-heated as seen in Table 2.1. Iodine reacts with the amylose compound in starch where it gets trapped in the amylose coils and blue-ish colour is formed after the addition of Lugols reagent (Fennema and others 2008). The absorbance readings came out higher for heated corn starch because iodine had more amylose to react with…
