Extract of sample "Alcaligenes faecalis"

Download file to see previous pages It is found in the alimentary tract as a harmless saprophyte in 5% to 19% of the normal population. This organism does not usually cause systemic infection. Alcaligenes faecalis has been reported to cause “sepsis, meningitis, peritonitis, enteric fever, appendicitis, cystitis, chronic suppurative otitis media, abscesses, arthritis, pneumonitis, and endocarditis” (Kavuncuoglu et al 118). Because Alcaligenes faecalis is resistant to commonly used antibiotics, the organism is associated with fatal outcomes. Thesis Statement: The purpose of this paper is to investigate Alcaligenes faecalis, and examine various aspects of the organism, its morphology and effects. Taxonomy, Morphology and Functions of Alcaligenes faecalis Hans Riemann and Dean O. Cliver argue that food borne diseases are increasing because of accelerated globalization of food supply, and emphasize the importance of finding new ways of detecting and identifying foodborne pathogens, and the elimination of food-related infections and intoxications. “Alcaligenes faecalis is a Gram-negative, oxidase-positive, and catalase-positive microorganism shaped in the form of a rod, coccal-rod or coccal” (Riemann and Cliver 343). The obligate aerobic bacterium moves with the help of peritrichous flagella, usually eight in number, but may occasionally be up to twelve. Some strains of the microorganism are capable of anaerobic respiration in the presence of nitrate or nitrite (Riemann and Cliver 343). Alcaligenes faecalis generally exists singly, and has a size of 0.5 – 1.0 x 0.5 – 2.6 um. The organism grows optimally at a temperature range of 20-370C. Although not considered as a major food-borne pathogen, it has caused occasional food-borne outbreaks with the typical symptoms of abdominal pain, headache, vomiting and diarrhoea. Further, “A. faecalis is an important food spoilage bacterium” ((Riemann and Cliver 344). Besides soil and water, the organism has been isolated from various sources such as medical specimens including body fluids and body waste matter, and from nematodes and insects. Some species of A. faecalis are commonly found in the intestinal tracts of vertebrates (Riemann and Cliver 344). The scientific classification of Alcaligenes faecalis (Vasanthakumari 335) is as follows: Kingdom: Bacteria Phylum: Proteobacteria Class: Beta Proteobacteria Order: Burkholderiales Family: Alcaligenaceae Genus: Alcaligenes Species: Alcaligenes faecalis (Vasanthakumari 335) Fig.1. White, Glistening Colonies of Alcaligenes faecalis on Blood Agar (Herrera, 2012) Paul G. Engelkirk and Janet L. Duben-Engelkirk observe that identification of Gram staining Alcaligenes faecalis and CDC Alcaligenes – like group 1 reveals that they cannot be differentiated from other non-fermenters. They have similar cellular morphology, and are motile by peritrichous flagella. The colonial morphology reveals that A. faecalis produces white colonies with a thin, spreading, irregular edge (Fig.1). Older colonies, as shown in the illustration above “tend to spread at the periphery and turn the agar a green-apple color” ((Engelkirk and Duben-Engelkirk 332). James T. Staley, Don J. Brenner, Noel R. Krieg and co-authors observe that the type subspecies faecalis of the Species Alcaligenes faecalis contains the type strain of the species. Its morphological characteristics are the same as those of the Genus Alcaligenes. Colonies of the organism on nutrient agar range in ...Download file to see next pagesRead More

Bacterial transmission

...). With this in mind, it is highly crucial to note that pathogen-microbe interactions in the host must be seriously considered with regard to disease severity and development. With respect to hospital surfaces, they are often contaminated with nosocomial pathogens. Due to the large number of people frequenting the areas of the library, there are pathogens present there as well (Bures et al. 2000; Kramer et al. 2006). 2.1.1. Enterococcus faecalis: 2001).With respect to nosocomial infections, E. faecalis is listed as the first to third leading cause (Glick, 2005). According to Alouf and Popoff (2006) many of these infections are experienced after abdominal surgeries or a puncture wound. Increased infections...

Differentiation of Microorganisms

..., KCN, MB agar, TSI agar, SS agar, and MacConkey agar. Discussion The culture media experiment used the following microorganism: Escherichis Coli, Enterococcus faecalis, and Pseudomonas aeruginosa. The two culture media in the experiment were synthetic medium and tryptic Soy Broth. The experiment examined the growth of the microorganisms in the two media. It was found out that the microorganisms had growth in the two culture media. Additionally, the culture media experiment examined the growth of microorganisms in SF Browth, Maccoonkey Agar and Color change, and Nutrient Agar and Glucose. The microorganisms used in these particular tests were Staphylococcus aureus, Enterococcus faecalis, Salmonella...

Membrane filtration (expriment)

...examination is crucial to determine the safety of drinking water. Presence of Enterococcus faecalis, Escherichia coli, Enterobacter aerogens and Proteus mirabilis in water sample was estimated using membrane filtration followed by incubation of the membrane filter in appropriate growth media to examine the determine the presence of pathogenic micro-organism. The motive to perform this study was to determine the presence of unknown organism(s) present in the provided samples. The study encompasses classification of bacteria based on their bio-chemical reactions, pH levels and osmoregulation. Identification and classification of bacteria from the sample is pragmatic as presence of any pathogenic micro-organism could be...

...antibiotics except ciprofloxacin. The E coli, S. aureus and E. faecalis are highly sensitive to antibiotics. Conclusion The individual genus groups of the bacteria are as follows; Klebsiella pneumoniae-MSU 1, M. tuberculosis- MSU 2, pseudomonas aeruginosa- MSU 3, S. Aureus- MSU 4, E. coli- MSU 5, E. faecalis- MSU 6 The MSU 1 belonged to a patient who experienced a recurrent vesicoureteric reflux; this is a condition characterized by a backflow of urine from the bladder to the kidneys. The most likely diagnosis was an infection by a bacterium of the enterobacteriace family. According to the laboratory results, the bacterium would be the Klebsiella pneumoniae. In this case, the most suitable antibiotics...

Vancomycin-resistant Entercocci

...to become resistant to Vancomycin it would be untreatable. (CHA 1996 pg 2) In the United States acquisition and transference of VRE outside hospital settings is not supported by data. Colonization nearly always precedes the majority of infections in European studies, which indicates that colonization occurs in the community. European reports also show that,”VRE exists in animal feces and in human foods originating in animals.” (McDonald, 1997 para 3). This implies a relationship between the community and nosocomical infections. The most common form of Entercocci is E. faecalis, responsible for 80% of colonizational human infections. As a possible weapon Entercocci are ideal in that they are an extremely resilient...

In order to further segregate the Micrococcus sp. presence or absence of glucose fermentation was observed. The result was negative confirming the absence of Micrococcus varians (which displays glucose fermentation) and presence of Micrococcus luteus (does not display glucose fermentation). B. Gram negative very short rods- The second unknown bacteria was aerobic as it was catalase as well as oxidase positive. Since it is Gram negative aerobic bacilli the identification tapers to the possibility of either Helicobacter salinarum, Alcaligenes faecalis, Pseudomonas aeruginosa. Since citrate utilization was...

Oxidation of acetaldehyde to acetate yields does not produce ATP, because the reaction proceeds directly with no intermediary production of acetyl-CoA iii) Alcaligenes Neither oxidizes nor ferments glucose Nonfermenters Oxidative Gram-Negative Bacilli, which also include Pseudomonas spp., release acid from glucose and carbohydrates only when oxygen is present (nonfermenters). It is wort noting that, Enterobacteriaceae , Vibrio andAeromonas are fermentative which utilize carbohydrates when oxygen is absent.
