Cocci

 

berry-shaped bacteria; diameter, 1–2 microns. Cocci are nonmotile and gram-positive, form no spores, and reproduce by transverse division.

Classified as cocci are Micrococci, Streptococci, Staphylococci, and Sarcina. On solid nutrient media cocci form round, smooth convex colonies (gray, white, yellow, or red). Cocci are widely distributed in nature, living in soil, air, and food products. Lactic-acid streptococci are used in making sour cream, butter, and clabbers. Pathogenic streptococci and staphylococci produce inflammatory processes and purulent diseases—for example, furunculosis, erysipelas, and angina.

This indicates that not only monomicrobial cultures were obtained, but also the associations of pathogens, where microbial spectrum dominated by Gram-positive cocci (S.
The Bruker Biotyper was also validated for identification of Corynebacterium species, generally perceived as a more challenging group of organisms to identify to the species level compared to common gram-negative bacilli and gram-positive cocci.
Although not FDA approved for this indication, this agent is routinely used at our hospital for UTIs due to drug-resistant gram-positive cocci.
The positive bottle is usually immediately tested using a Gram stain, with Gram positive or Gram negative organisms reported, including also information on cell morphology--usually rods, cocci, clusters, or chains.
Out of 11 isolates, five were Gram's positive rods, five were Gram's positive Cocci, and only one was Gram's negative Cocci which were isolated from different composts.
Azyter is effective against the majority of Gram positive cocci (Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumonia), Gram negative species (such as Haemophilus influenzae, commonly isolated in eye infections in children) as well as intracellular germs (Chlamydia).
The purpose of the automated image analysis of digital bacterial cell image is to identify the type of bacteria whether it is bacilli or cocci or spiral based on their geometric features using different classification techniques, namely, 3[sigma] classifier, K-NN classifier, Neural Network classifier and Fuzzy classifiers.
