Gram-positive bacteria

Following Gram staining and microscopic examination, Unknown 15 was identified to be a Gram positive coccoid. Based on these results, all of the Gram negative genera were eliminated including: Enterobacter, Citrobacter, Klebsiella, Escherichia, Pseudomonas, Serratia, Alcaligenes, Neisseria, Proteus, Salmonella, Shigella, Erwinia, Veillonella, and Flavobacterium (5). Bacillus, Lactobacillus, Listeria, Kurthia, and Arthrobacter were eliminated because they did not match the coccoid shape of…

Plant Material Collection Fully grown whole plants of Tribulus terrestris Linn. were collected from different localities of Chennai, Tamilnadu. The fruits were separated out from the plants and washed in running tap water to remove adhering dirt and soil particles and dried first under shade in room temperature and secondly in a hot-air oven for complete drying at 50-60˚C. The dried fruits were made into coarse powder by grinding and stored in labelled bottles for further study and…

growth of bacteria facilitating the dissolution and also helps in mineral transport. The moisture of the digestate increases with the increase of VS and TS reduction. 5.3.1.6. Phosphate Content Phosphate content is an important parameter for the growth of plant. Phosphorous is a macronutrient needed for the growth of plant. Phosphate maintains a stable anaerobic digestion process in the digestate. The amount of phosphorous present at the start of the digestion process was 0.24 mg/100 gram of…

5.3 Responses to probiotic bacteria and microbiota Pathogenic bacteria are not the only bacteria that elicit immune responses in the intestine as probiotic bacteria have also been tested as a food supplement to improve fish health. Few studies have evaluated the impact and regulation of Igs after probiotic administration. Most of these studies showed an increase in IgM secretion and/or expression after probiotic administration (Picchietti et al., 2007; Sun et al., 2010). However, a…

celled bacteria and has organelles, not bounded by a membrane. They are asexual and reproduce by binary fission. It belongs to Kingdom Bacteria because it has peptidoglycan in its cell wall. It is unicellular and lack nucleus. It is obligate anaerobe as well as have ability to produce by spore so it falls under Phylum Firmicutes. It is classified in class Clostridia and further in order Clostridiales due to its spore forming ability. It is in Genus Clostridium because of being gram positive rod…

The differential diagnosis that fits 5-year-old Johnny is Impetigo. Impetigo is caused by Staphylococcus aureus or Streptococcus pyogenes, which are Gram-positive bacterias that are highly contagious (Hartman-Adams, Banvard, & Juckett, 2014). According to Hartman-Adams, Banvard, & Juckett (2014), it is the most common bacterial skin infection seen in children between the ages of two and five years old. The symptoms associated with impetigo are classified as ruptured oozing sores, and…

breaks down glucose in the absence of oxygen. The energy released from glucose would convert into acids, gases or alcohol. Fermentation would take place when the electron transport chain would not be used. Fermentation would occur in yeast cells, bacteria and in muscle cells of animals. For most methods of fermentation metabolism, glycolysis would involve the breaking down of 6 carbons into two phosphoglyceraldehydes then to biphosphoglycerate by putting energy into the process. Electrons are…

Despite humans encountering if for millennia, pneumonia caused by Streptococcus pneumoniae remains one of the deadliest microbiological threats facing humanity today. S. pneumoniae is a Gram positive, diplococcus bacteria with ore than 90 serotypes1. Along with pneumococcus pneumonia, S. pneumonia can cause meningitis, sepsis, bacteremia, and otitis media1,2. It is the leading cause of community acquired pneumonia, as well as fatal respiratory infections globally, across all age ranges; severe…

The culture growth takes 3-7 days and is gram-negative. Polymerase chain reaction analysis is also specific and more sensitive than a culture. It is used to detect pertussis bacterium DNA sequences. This technique can be used after the patients has already begun antibiotics and does not require a living bacterium to be effective. Serology is mostly used for patients in the convalescent stage of the disease when a culture sample is unlikely to return positive. this test may not be effective in…
