Klebsiella pneumoniae

methylene blue( EMB) agar and 5.12 x 108 cfu/mg soil on MacConkey (MCC ) agar, indicating that the bacterial count is higher on MCC than on EMB. The bacterial isolates and their frequency of isolation from dumpsites were Escherichia coli (33.3%), Klebsiella spp.(16.7%) ,Pseudomonas spp. (13.3%), Proteus spp.(10%), Streptococcus spp. (8.3%), Salmonella spp. (6.7%), Staphylococcus aureus (6.7%) and Enterobacter spp. (5.0%). The high presence of pathogenic bacteria from dumpsites is of serious…

Neisseria, in addition to Actinomycetes and Fusobacteria. Resistance to bacitracin is extremely uncommon. Meanwhile, neomycin acts on both gram-positive and gram-negative pathogens including staphylococci, Proteus, Enterobacter aerogenes, Klebsiella pneumoniae, Salmonellae, shigallae, Haemophilus influenza, Pasteuerella, Neisseria meningitides, Vibro cholera, Bordetella pertussis, Bacillus anthracis, Corynebacterium diptheriae, Streptococcus faecalis, Listeria monocytogenes, Escherichia coli…

nonfermenters. BCP (lactose) broth which was originally a purple colored medium turned into a color yellow and signs of gas production was also noted. The result indicated that the unknown #63 was positive for both acid and gas production and eliminated K. pneumoniae, and E. aerogenes because they can produce acid, but no gas production was suggested from the dichotomous key. The test result for SIM deep slant that was used to test for sulfur-reducing turned up positive due to its color changed…

R.S. Baylock 2001 studied bacterial…

respective ligand. According to Ewald (2011) there are three good options, CitX (periplasmic binding protein from Salmonella typhimurium) and the binding domains of DpiB (sensor histidine kinase from E. coli) and CitA (sensor histidine kinase from Klebsiella pneumoniae). We would then purify all three proteins and record fluorescence energy values when bound to citrate for future reference. It is also crucial to test the purified proteins affinity against pyruvate and other citric acid cycle…

pink. This outcome eliminated Klebsiella pneumonia as a possibility. The Urea test indication concluded that the Unknown #29 was Enterobacter aerogenes. But for good measure as a Final test I used the Methyl Red-Vogues Proskauer test to double check my results. The MR-VP test was performed, giving the expected negative result. This indicated that the unknown did not produce acids as a byproduct of glucose metabolism. The negative result eliminated K. pneumoniae from the list of remaining…

Sara Parks Unknown Report Introduction One of the many reasons to study microbiology is to gain a better understanding of microorganisms and the huge part they play in the world. It is imperative to know the differences between microorganisms. This knowledge is useful in many cases; for instance, a patient with an unidentified infection could be administered effective treatment if one possessed the knowledge to correctly define the microorganism. Furthermore, the purpose of this unknown…

Chitin is the second most abundant natural polysaccharide consisting of β(1→ 4)-linked N-acetyl-D-glucosamine (GlcNAc) units in a linear form. Chitin is insoluble in water and mainly exists in two crystalline (α- and β-) forms. The α-chitin consists of sheets of tightly packed alternating parallel and antiparallel chains (1) and is abundant in the exoskeleton of arthropods, insects, fungi, and yeast cell walls. The chains are arranged in parallel orientation in β-chitin (2), which occurs less…

with severe sepsis or septic shock and c Respiratory failure treat with an extended spectrum beta-lactam and either an aminoglycoside or fluoroquinolone to cover for Pseudomonas c Bacteremia treat with beta-lactam and macrolide for Streptococcus pneumoniae c Possible multi-drug resistant bacterial pathogens use combination therapy - Empiric combination therapy should not be used for more than 3-5 days c Deescalate to the most appropriate single therapy as soon as susceptibility profile is known…

Introduction: Resistance to antibiotics is an ongoing concern of the pharmaceutical industry. The limited number of antibiotics in the market to treat Gram negative bacteria made their resistance an issue that is being addressed worldwide. The isolation of colistin from Bacillus polymyxa var. colistinus in Japan in 1949 and the introduction of colistin into the market in 1959 as its inactive prodrug colistin methanesulfonate (CMS) were significant milestones in the treatment of this type of…
