![]() ![]() This is a Gram-positive saprophytic bacterium that appears as a tetrad. It causes many human problems starting from skin rashes to fatal contamination and even leading to sepsis. These are Gram-positive, aerotolerant bacteria that appear as a chain of cocci. These are also present in the alimentary tract of ruminant animals. Mostly these are associated with UTI, sepsis, and also colorectal cancer. This Gram-positive, catalase-negative, lactic acid bacterium appears as chains of cocci or remains in pairs. These are coagulase-negative, Gram-positive bacteria. It remains as an opportunistic bacterium for immunocompromised patients. This bacterium shows non-coagulase activity with coccoid-shaped cells. However, it can become opportunistic bacteria once inside the human body. This is a facultative anaerobe, Gram-positive bacterium that occurs frequently on human skin. They are arranged either in tetrads or cuboids. This bacterium is anaerobic, endospore-forming Gram-positive that has coccoid cells. ![]() They are present in nasopharynx of humans and cause bacterial meningitis. This is a Gram-negative bacterium occur in pairs. These are extensively used in fermenting soy sauce. They can grow in extremely salt conditions and are tolerant to 18% NaCl solution. This is a Gram-positive, halophilic anaerobe, a coccoid-shaped lactic acid bacterium. Streptococcus From Creative commons Tetragenococcus halophilus It is a Gram-positive, catalase-negative spherical bacteria that appear in a cluster of cocci. Some spherical bacteria examples are listed below: Aerococcus urinae Spherical bacteria have characteristic round or spherical shape as seen under a microscope, can be categorize depending upon the arrangement of cocci cells and also the plane of division. Bacteria are classified based on their shapes, i.e., bacillus ( rod-shaped), cocci ( spherical shaped), and spirochetes ( spiral-shaped). Some appear as round, spherical while others appear as rod shaped. Micrococcus roseus What are spherical bacteria?īacteria are single celled microorganisms that occur in various shapes.The spherical bacteria examples are as follows: This article will provide insights regarding some spherical bacteria examples. Spherical bacteria are usually spherical, ovoid, or round in shape referred as coccus (pl. The morphology of the bacteria has been used as a phylogenetic tool which suggested that spherical bacteria is the most evolved morphology. ![]()
