flora

Examples of flora in the following topics:

• Suppression and Alteration of Microbiota by Antimicrobials

  • Our bodies depend upon, and host, a vast number of complex microbial flora that can be affected negatively by antimicrobial treatments.
  • The human body hosts thousands of different species of microbial organisms, known as the microbial flora or microbiota.
  • An example is gut flora getting into the body's blood stream.
  • In the case of the gut flora, this may impair the ability of a patient to properly metabolize food.
  • In addition to serving a necessary function as gut flora due in metabolism of food, some microbiota in our bodies serve the function of keeping pathogenic microbes from inhabiting or dominating other flora at locations in our body.

• Normal Gastrointestinal Microbiota

  • Gut flora consist of microorganisms that live in the digestive tracts of animals and are the largest reservoir of human flora.
  • Gut flora consists of microorganisms that live in the digestive tracts of animals and is the largest reservoir of human flora .
  • It is estimated that these gut flora have around 100 times as many genes in aggregate as there are in the human genome.
  • Bacteria make up most of the flora in the colon and up to 60% of the dry mass of feces.
  • Fungi and protozoa also make up a part of the gut flora, but little is known about their activities.

• Innate Resistance

  • Many of the bacteria in the digestive tract are collectively referred to as the gut flora .
  • Normal flora bacteria can act as opportunistic pathogens at times of lowered immunity.
  • The gut flora is the human flora of microorganisms that normally live in the digestive tract and can perform a number of useful functions for their hosts.
  • It is the largest reservoir of human flora.
  • In this context, gut is synonymous with intestinal, and flora with microbiota and microflora.

• Overview of Human-Microbial Reactions

  • Human-microbial interactions can be commensal or mutualistic, as with many types of gut flora, or harmful, as with pathogenic bacteria.
  • Gut flora consists of microorganisms that live in the digestive tracts of animals and is the largest reservoir of human flora.
  • Bacteria make up most of the flora in the colon and up to 60% of the dry mass of feces.
  • Fungi and protozoa also make up a part of the gut flora, but little is known about their activities.
  • Skin flora are usually non-pathogenic and either commensal or mutualistic.

• Microbiota of the Skin

  • The skin flora, more properly referred to as the skin microbiome or skin microbiota, are the microorganisms that reside on the skin.
  • The skin flora, more properly referred to as the skin microbiome or skin microbiota, are the microorganisms that reside on the skin.
  • Skin flora are usually non-pathogenic, and either commensals (are not harmful to their host) or mutualistic (offer a benefit).
  • There are three main ecological areas for skin flora: sebaceous, moist, and dry.
  • Describe the types of skin flora and how they can be beneficial for the organism

• Bacteroides and Flavobacterium

  • The presence of bacteroides in the normal flora of mammals is indicative of its role in processing complex molecules to simpler ones that can be utilized by the host.
  • The role of bacteroides in the normal flora extends beyond their ability to breakdown larger complex molecules and can display protective function.
  • Describe the role of Bacteroides in the normal flora of the human gastrointestinal tract and the role of Flavobacterium in causing disease in freshwater fish

• Normal Genitourinary Microbiota

  • Those that are expected to be present and that under normal circumstances do not cause disease, but instead participate in maintaining health, are deemed members of the normal flora.
  • Normal flora bacteria can act as opportunistic pathogens at times of lowered immunity.The vaginal microflora consist mostly of various lactobacillus species .
  • Disturbance of the vaginal flora can lead to bacterial vaginosis.

• Control of Nosocomial Infections

  • Two categories of micro-organisms can be present on health care workers' hands: transient flora and resident flora.
  • The microbes comprising the resident flora are: Staphylococcus epidermidis, S. hominis, and Microccocus, Propionibacterium, Corynebacterium, Dermobacterium, and Pitosporum spp., while in the transitional could be found S. aureus, and Klebsiella pneumoniae, and Acinetobacter, Enterobacter and Candida spp.
  • The goal of hand hygiene is to eliminate the transient flora with a careful and proper performance of hand washing, using different kinds of soap, both normal and antiseptic, and alcohol-based gels.

• Antibiotics and Selective Toxicity

  • Common side-effects include diarrhea, resulting from disruption of the species composition in the intestinal flora, resulting, for example, in overgrowth of pathogenic bacteria, such as Clostridium difficile.
  • Antibacterials can also affect the vaginal flora, and may lead to overgrowth of yeast species of the genus Candida in the vulvo-vaginal area.

• Bacterial Skin Diseases

  • Cellulitis can be caused by normal skin flora or by exogenous bacteria, and often occurs where the skin has previously been broken.
  • Group A Streptococcus and Staphylococcus are the most common of these bacteria, which are part of the normal flora of the skin, but normally cause no actual infection while on the skin's outer surface.
