What is the colony morphology of Staphylococcus Saprophyticus?
Staphylococcus saprophyticus is a coagulase-negative species of Staphylococcus. Like other Staphylococci, it is Gram-positive, is globular shaped, and is a facultative anaerobe. It has abundant transporter systems to adapt to ever changing pH, osmolarity, and concentration of urea in human urine.
What are the characteristics of Staphylococcus?
Characteristics. Staphylococci are Gram-positive, nonspore forming, facultatively anaerobic, nonmotile, catalase-positive or negative, small, spherical bacteria from pairs to, grape-like clusters, from where the name Staphylococcus comes from (staphyle, meaning a bunch of grapes, and kokkos, meaning berry).
What is the morphology of Staphylococcus epidermidis?
Cellular morphology and biochemistry Staphylococcus epidermidis is a very hardy microorganism, consisting of nonmotile, Gram-positive cocci, arranged in grape-like clusters. It forms white, raised, cohesive colonies about 1–2 mm in diameter after overnight incubation, and is not hemolytic on blood agar.
What does Staphylococcus Saprophyticus cause?
Staphylococcus saprophyticus is a Gram-positive bacterium that is a common cause of uncomplicated urinary tract infections, especially in young sexually active females. It is also responsible for complications including acute pyelonephritis, epididymitis, prostatitis, and urethritis.
What is the characteristic appearance of Staphylococcus in culture?
Staphylococci are Gram-positive cocci about 0.5 – 1.0 μm in diameter. They grow in clusters, pairs and occasionally in short chains. The clusters arise because staphylococci divide in two planes.
What is the colony morphology of Bacillus subtilis?
Bacillus subtilis is a typical germ, which is rod-shaped and Gram-positive. When cultured on ordinary nutrient agar, the morphology circular colony of this bacteria is rough, opaque, fuzzy white or slightly yellow with jagged edges [1, 7].
Is Staphylococcus aureus harmful?
Staphylococcus aureus is the most dangerous of all of the many common staphylococcal bacteria. These gram-positive, sphere-shaped (coccal) bacteria (see figure How Bacteria Shape Up) often cause skin infections but can cause pneumonia, heart valve infections, and bone infections.
What is the disease caused by Staphylococcus aureus?
Staph infections may cause disease due to direct infection or due to the production of toxins by the bacteria. Boils, impetigo, food poisoning, cellulitis, and toxic shock syndrome are all examples of diseases that can be caused by Staphylococcus.
Is Staphylococcus a halophile?
Staphylococcus aureus is a Gram-positive non-spore-forming coccus that is often part of. the normal microflora of the human skin, nose, throat and mouth. . S. aureus is a facultative anaerobe, is a facultative halophile, and produces enterotoxins .
What are the characteristics of Staphylococcus aureus?
Morphology. The microscopic appearance of Staphylococcus aureus is round and resembles that of a sphere (cocci).
