Citrobacter is a gram … Streptococcus organisms are Gram positive, microaerophilic and non-motile bacteria. Micrococci are microbiologically characterized as gram-positive cocci, 0.5 to 3.5 μm (micrometres; 1 μm = 10-6 metre) in diameter. Probiotic bacteria protect these sites by taking up position and establishing a protective barrier in the gut. 5 GRAM- Positive- Cocci- Staphylococci. BACKGROUND. can diagnosis on … Many authors continued to place motile cocci in the genus Micrococcus, arguing that motility was not sufficient grounds to place the organisms in a completely different genus.However, it was demonstrated subsequently that the mol% G + C content … SWANNELL AND I.M. Gram-stain: Negative = 0, Positive = 1, Indeterminate = 2: Found in human microbiome: Microbes that live anywhere in the human body and are not pathogenic to humans (i.e. Strain NEAU-ST10-9(T) is a moderately halophilic, coccoid and non-motile bacterium isolated from saline and alkaline soils in the Dechang Township, Zhaodong City, China. Bacteria of this genus are of primary clinical significance. Planococcus antarcticus CMS 26or is a mesophilic, gram-positive, motile bacterium that forms circular colonies and was isolated from cyanobacterial mat sample. A novel aerobic, Gram-stain-positive, motile, moderately halophilic and coccoid bacterial strain, designated LCB217 T, was isolated from a saline-alkali soil in north-western China and identified using a polyphasic taxonomic approach.Growth occurred with 3-15 % (w/v) NaCl (optimum 3-5 %), at 10-45 °C (optimum 30 °C) and at pH 7.0-9.0 (optimum pH 9.0). It can form in tetrads or irregular clusters but not in chains and belongs to the family Micrococcaceae. Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia.It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest.It is associated with citrus, but it attacks a wide range of … B. May cause opportunistic infection in an immunocompromised host. A. True. Sometimes, these measurements are the only differences needed to distinguish between two closely related species. Culture in Blood Agar and MacConeky Agar.
