Research Paper On Clostridium Perfringens

Clostridium difficile is a gram positive, spore forming anaerobic bacillus, which may or may not carry the genes for toxin A-B production (Nipa, 2010). These two types of protein exotoxins produced by the Clostridium difficile bacillus, toxin A and toxin B, can have an infectious form and a non-active, non-infectious form (Grossman, 2010). The infectious form can survive for a short duration of time in the environment. The spores can survive for a longer period of time in the environment and are not infectious unless and until they are ingested or are transformed into an infectious state (Nipa, 2010).

Clostridium Difficile (C-Diff) is considered one of the most common infections a patient can acquire within their hospital stay. It is estimated that C-Diff is responsible for 337,000 infections and 14,000 deaths a year (Centers for Disease Control and Prevention, 2012). Working in the emergency department (ED), I have witness first hand how debilitating this gastrointestinal infection can be. Patients are admitted to the ED for having severe watery diarrhea, abdominal pain, and fever. Elderly patients are at increase risk for sepsis and dehydration related to recurrent infections. Appropriate management and education of C-Diff is optimal for patient survival and decrease contamination across lifespan.

Many Americans die each year from complications connected to Clostridium difficile. It can ill a significant number of individuals as well as animals. The Clostridium difficile infection is the result of poor hygiene, misuse, overuse of antibiotics and an aging population. In this paper I will be discussing the following topics, what clostridium difficile means, what it causes, signs and symptoms, complications, treatment and the prevention.

761). Since the nutrients in the intestines are available due to the good bacteria being destroyed, Clostridium difficile uses the nutrients to multiply and releases the toxins , which attack the lining of the intestines, thus causing colitis (Fordtran, 2006, pp. 3).

The healthcare professional can expect to encounter various conditions within their scope of experience. Clostridium difficile represents one of the most common and challenging nosocomial infections that can cause life-threatening complications such as hypervolemia, sepsis, pain, and peritonitis (Grossman and Mager 155). The recognition, diagnosis, treatment and inhibition of transmission of this bacterium are imperative in order to limit infection and prevent death.

Clostridium difficile was discovered and isolated from neonates in 1935. It was initially considered a component of the fecal flora of newborns and not thought to be pathogenic (Keessen, Gaastra, & Lipman, 2010). The history of C. diff and other antibiotic resistant pathogens are closely related with the history of antibiotics. The first antibiotic discovered was penicillin by Alexander Fleming while working with Staphylococcus. With this discovery, a surge of natural and synthetic drugs was discovered to treat bacterial infections. During the 1970s, clindamycin and cephalosporins were highly used as an effective antibiotic against bacterial infection but at the same time disrupted the normal, healthy bowel flora, allowing C.

difficile lies within the 19.6 kb pathogenicity locus (PaLoc) and codes for two major virulence factors and three accessory proteins [9]. Genes tcdA and tcdB encode Toxin A and Toxin B, respectively, the two major virulence factors which are part of the clostridial glucosylating toxin family [10]. Both catalyze the inactivation of Rho-GTPases, which are essential for the regulation of eukaryotic cell cytoskeleton [9]. The inactivation of Rho-GTPases causes cell death via cytoskeletal disorganization [9]. The accessory gene functions are as follows; tcdE as a putative holin protein; tcdD as a positive regulator and tcdC as a negative regulator, both of which are controlling Toxin A and B gene expression

Clostridium difficile is a gram-positive bacterium which causes diarrhoea. It also known as antibiotic associated diarrhoea and also pseudomembranous colitis. The bacterium secretes large protein toxin that also causes toxic mega colon. Clostridium difficile is caused by when a person is given one of the following antibiotics: Cephalosporin, penicillin (particularly Ampicillin or Amoxicillin), Clindamycin and Fluoroquinolone. The antibiotic will remove the entire normal flora in the colon. The lack of normal flora will make the person vulnerable to infection especially to Clostridium difficile because Clostridium difficile produces hardy spores

Many different diseases are caused by different species in the Clostridium genus, including tetanus, botulism, and gangrene ("Clostridium."). But perhaps the worst, but least publicly recognized, is Clostridium difficile, or CDI. This disease affects 500,000 people every year in the US alone, and of those infected, around 6% died within the first month of being infected (“Healthcare-Associated Infections.”). CDI is a gastrointestinal infection. It is found in soil, water, processed meat, and human and animal feces, but once the bacteria has reached a surface, it can linger there for months. If people touch a surface with CDI with their hands, they can then accidentally ingest it, leading to a potential CDI infection. Certain people are at much

This test is performed to check for Clostridium difficile bacteria in your stool. Being infected with this toxin can result in damage to the lining of your colon and may lead to colitis.

Each year in the United States, many people require hospitalization due to various medical reasons. Often times, patients must undergo a course of antibiotics to treat the medical condition that warranted the hospitalization. The combination of the necessity to be admitted to a health care facility along with the administration of an antibiotic may result in a Clostridium difficile infection (CDI). The purpose of this paper is to provide an overview of a CDI, including an overview of the microbiology of Clostridium Difficile (C- diff), as well as the epidemiology, pathophysiology, signs, symptoms, treatment and prevention of the infection.

Clostridium perfringens are bacteria that produce harmful toxins to humans. Clostridium perfringens and its toxins are found everywhere in the environment, including soil, dust and, animals. but human infection is most likely to come from eating food that is contaminated with Clostridium perfringens in it. Food poisoning from Clostridium perfringens is very common, but is typically not too severe, and is often mistaken for the “24-hour flu”.

A new strain of Clostridium botulinum has been discovered that has caused many problems. To begin, this discovery is important as this strain of Clostridium botulinum is responsible for the deadly illness, botulism. As a result, the scientists that discovered this new strain, they decided to keep their findings to themselves and not to to the public. Not to mention that another reason why this new strain of Clostridium botulinum is important is because it is one of the first to be identified in 40 years. Ultimately, the finding of the new strain of Clostridium botulinum is important as it could affect the future effectively.

Furthermore, dangerous strains of E. coli, such as E. coli O157:H7, produces toxins such as Shiga toxins. These toxins have the capabilities to damage the lining of the small intestine, which can result in stomach cramps, diarrhea, vomiting, nausea and bloody stool. If a person can come into contact with a contaminated source, symptoms can appear about three to four days after exposure and can usually last between one to nine days. The infected host is considered contagious until their symptoms stop and even a couple days after that. The way E. coli O157:H7 is diagnosed is by a special stool culture that is sent to a stool laboratory, where tests are run to

The genus name refers to a spindle, and the species name means tension which is appropriate since Clostridium tetani causes Lockjaw. The taxonomic information is: Domain Bacteria, Phylum Firmicutes, Class Clostridia, Order Clostridiales, Family Clostridiaceae, Genus Clostridium, Species tetani.
