Spherical-shaped bacteria Spherical-shaped bacteria are called cocci e.g. M. tuberculosis and M. leprae, the most notorious species, are the causative agents for tuberculosis and leprosy, respectively. Bacteria, like the ones called cocci and bacilli, are used to make some of our favorite foods, including cheese, pickles, and soy sauce. These infections include strep throat, pneumonia, food poisoning, otitis media, various skin diseases, meningitis and severe types of septic shock. Bacteria are classified according to their shape, or morphology. Coccus bacteria are those bacteria which have round shape. The goodness and badness of bacteria do not depends upon its shape. Some of them are good and some of them are bad. For example, Staphylococcus epidermidis is cocci but found as normal flora on our skin so it is good bacteria. Occur as single cells, pairs, chains or clusters. 1. Most bacteria are helpful, but some should be avoided. The campylobacter bacteria is the most common cause of food poisoning in the UK. Helicobacter pylori. Bacteria (bak-TEER-ee-uh) are tiny, single-celled organisms that get nutrients from their environments. b. they are plant-like, but lack chlorophyll. A bacterial infection is a proliferation of a harmful strain of bacteria on or inside the body. The campylobacter bacteria is the most common cause of food poisoning in the UK. Bacteria that cause UTI are divided into two main classes: gram-negative and gram-positive bacteria. Listeria. Some bacteria are harmful to humans, but most are not. Clostridium perfringens. This article focuses on the bacteria that are pathogenic to humans. Bacteria that forms waxy like shells and turns into spores when the conditions aren't favorable for them. The bacteria are usually harmless, but infections can occur on broken skin or within a blocked sweat or sebaceous gland, resulting in boils, pustules and abscesses. Others include Campylobacter, which is the main cause of food poisoning among humans. a. the three major types are cocci, bacilli, and pathili. 5 Types of Bacteria According to Gram Staining: Coccus – These are rounded or spherical in shape and may occur in chains or clusters.

Some types of bacteria, however, are harmful to humans. Spiral-shaped bacteria Spiral-shaped bacteria are called spirilla e.g. Plants 3. It is also a frequent cause of otitis media (infection of the middle ear) and meningitis. Typical of what might be seen in milk and dairy products are: Cocci ----- Spherical cells, 0.4 - 1.5 microns. The cell walls are referred to as, 'lipopolysaccharide,' or, 'endotoxins.' The cocci bacteria are responsible for illnesses such as streptococcal and staphylococcus. (e.g., Genera - Streptococcus, Staphylococcus). To cause disease, these pathogenic bacteria invade a living organism due to poor hygiene, unsanitary water, and poor sewage treatment centers.
