  2. Rhodococcus equi - Wikipedia

    en.wikipedia.org/wiki/Rhodococcus_equi

    Rhodococcus equi is a Gram-positive coccobacillus bacterium. The organism is commonly found in dry and dusty soil and can be important for diseases of domesticated animals (horses and goats). The frequency of infection can reach near 60%. [1] R. equi is an important pathogen causing pneumonia in foals.

  3. Bacterial cellular morphologies - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cellular...

    Coccobacillus: Oval and similar to coccus (circular shaped bacterium). [22] There is no connection between the shape of a bacterium and its color upon Gram staining; there are both gram-positive rods and gram-negative rods. MacConkey agar can be used to distinguish among gram-negative bacilli such as E. coli and salmonella. [23]

  4. Gram-positive bacteria - Wikipedia

    en.wikipedia.org/wiki/Gram-positive_bacteria

    Violet-stained gram-positive cocci and pink-stained gram-negative bacilli. In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall.

  5. Rhodococcus - Wikipedia

    en.wikipedia.org/wiki/Rhodococcus

    Rhodococcus is a genus of aerobic, nonsporulating, nonmotile Gram-positive bacteria closely related to Mycobacterium and Corynebacterium. [2] [3] While a few species are pathogenic, most are benign, and have been found to thrive in a broad range of environments, including soil, water, and eukaryotic cells.

  6. Gram stain - Wikipedia

    en.wikipedia.org/wiki/Gram_stain

    Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection . [ 1 ]

  7. Pasteurella multocida - Wikipedia

    en.wikipedia.org/wiki/Pasteurella_multocida

    Pasteurella multocida is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus of the family Pasteurellaceae. [1] Strains of the species are currently classified into five serogroups (A, B, D, E, F) based on capsular composition and 16 somatic serovars (1–16).

  8. Fannyhessea vaginae - Wikipedia

    en.wikipedia.org/wiki/Fannyhessea_vaginae

    It is a facultative anaerobic, Gram-positive rod-shaped or elliptical coccobacillus found as single elements or in pairs or short chains. [2] It is typically isolated from 80% of women with bacterial vaginosis and it is implicated in treatment failures. [3] [4] Invasive infections such as bacteremia have been reported. [5]

  9. Enterococcus raffinosus - Wikipedia

    en.wikipedia.org/wiki/Enterococcus_raffinosus

    Enterococcus raffinosus is a bacterial species of the Gram-positive genus Enterococcus, named for its facultative anaerobic metabolism, including the ability to ferment the trisaccharide raffinose. [1] This mesophilic microaerophile has optimal growth at 37°C in Columbia Blood Medium (agar mixture of trypticase soy and brain heart infusion). [2]
