What is the difference between cocci and bacilli bacteria

Untreated periodontitis can cause loose teeth and even tooth loss. Symptoms of periodontitis include swollen gums, red or purple gums, bleeding gums, bad breath, and pain when chewing. Early symptoms include a low fever, runny nose, and cough. In infants, it can also cause apnea, which is a pause in breathing.

Plague is caused by the coccobacillus Y. Historically, Y. According to the World Health Organization , there were more than 3, cases of plague reported between and , causing deaths. Symptoms of plague can include a sudden fever, chills, headache, aches and pains throughout your body, a feeling of weakness, nausea , and vomiting.

Brucellosis is a disease caused by coccobacilli from the genus Brucella. However, humans can get it from eating or drinking unpasteurized dairy products. Symptoms of brucellosis include headache , feelings of weakness, fever, sweating, chills, and body aches. Coccobacilli are responsible for many conditions that cause a variety of symptoms, so treatment often depends on the type of illness you have.

The first step in treating coccobacilli-related infections is taking antibiotics. Whooping cough and plague are both much less common today than they used to be, thanks to vaccines against B. The Centers for Disease Control and Prevention recommends that all babies, children, preteens, teenagers, and pregnant women be vaccinated against whooping cough.

The H. However, today fewer than 50 cases of H. Bacillus is mostly arranged as a single bacteria. A single curved rod is called vibrio. Other different shapes of bacilli are filaments, club-shaped rods, spirochetes, spindle-shaped rods, and spirillum. Examples for each bacilli shapes are given in table 2. During multiplication, different arrangements of bacilli are found: diplobacilli, streptobacilli and coccobacillus. Diplobacilli is the side by side arrangement of two bacteria.

Streptobacilli are bacterial chains. Coccobacillus is short rod-shaped bacteria. Haemophilus influenzae , Gardnerella vaginalis, and Chlamydia trachomatis.

Bacilli are either endospore-forming aerobic or facultatively anaerobic. They are associated with bacteremia meningitis, endocarditis and infectious wounds in the eye, ear, urinary tract and respiratory tract. Two orders of bacilli is found: Bacillales and lactobacillus. Almost all bacilli are gram positive.

Gram staining of the Bacillus subtilis is shown in figure 2. Figure 2: Bacillus subtilis. Cocci: Cocci are either spherical, oval, bean or kidney-shaped. Bacilli: Bacilli are either rod, vibrio, filamentous, spirochetes, spindle or spirillum-shaped.

Cocci: One axis of the bacterium is almost the same as the other. Bacilli: One axis of the bacterium is longer than the other. What is peptidoglycan made up of? How does peptidoglycan affect gram staining?

How do pili help bacteria? How do antibiotics affect peptidoglycan? See all questions in Bacteria. Impact of this question views around the world. Cocci that divide in three planes and remain in groups cube like groups of eight. The cocci are arranged in grape-like clusters formed by irregular cell divisions in three plains. Examples: Haemophilus influenzae , Gardnerella vaginalis , and Chlamydia trachomatis. The bacilli bend at the points of division following the cell divisions, resulting in a palisade arrangement resembling a picket fence and angular patterns that look like Chinese letters.

Spirilla or spirillum for a single cell are curved bacteria which can range from a gently curved shape to a corkscrew-like spiral. Many spirilla are rigid and capable of movement. A special group of spirilla known as spirochetes are long, slender, and flexible. They have rigid spiral structure. Spirillum with many turns can superficially resemble spirochetes. They do not have outer sheath and endoflagella, but have typical bacterial flagella.

Example: Campylobacter jejuni, Helicobacter pylori , Spirillum winogradskyi, etc. Spirochetes have a helical shape and flexible bodies. Spirochetes move by means of axial filaments, which look like flagella contained beneath a flexible external sheath but lack typical bacterial flagella. Examples: Leptospira species Leptospira interrogans , Treponema pallidum , Borrelia recurrentis , etc. They are very long thin filament-shaped bacteria. These bacteria do not have any characteristic shape unlike all others described above.

They can change their shape. In pure cultures, they can be observed to have different shapes. In the classification of bacteria by staining, differential staining methods gram stain and acid fast stain methods are used.

In the gram staining method bacteria are stained as either positive or negative gram cells using a dye-iodine complex which permeat the cell wall of a gram- negative cell but not gram positive bacteria cell as it permit the outflow of the iodine complex during decoloration.. As in acid- fast staining certain bacteria such as the tubercle baccilli resist decoloration with acids. This is how bacteria are classified by staining method. You said in the introduction that bacteria do not have chlorophyll, but that is untrue.

There are still many kinds of free-living photosynthetic bacteria, or cyanobacteria, in existence. But that would be both pedantic and confusing to your readers….
