Does a micrococcus luteus is positive for capsule stain?
yes as it have capsule it give positive test for capsule staining when stain with malachite green The problem with the above answer is that a capsule stain is NOT done with malachite green.
What is the color of the capsule in the capsule stain?
When a stain, such as an acid dye, cannot penetrate the outer layers of a microbe, the cell will appear transparent on a colored background. This stain is called a negative or background stain. It is performed by mixing the dye with a suspension of bacteria on a slide and spreading the mixture into a thin layer for viewing. The capsule is a structure surrounding the cell wall that certain bacteria can produce. The ability to form a capsule is genetically and environmentally controlled. Only those microbes with the genes for capsule production have the potential to manufacture this polysaccharide (or polypeptide) surface layer. Special nutrients or other growth factors often are necessary for the genes to be expressed. The role of the capsule is primarily for protection of the bacteria. For example, the capsule affords a seal against dehydration. Many capsules repel white blood cells and thus allow pathogenic invading bacteria to elude one of the primary host defenses. Capsules are not readily stained and therefore are visualized by negative stain techniques. The organisms are prepared as a smear in the presence of an acid dye and allowed to air dry because heat will cause the capsule to shrink. Our procedure will combine a negative stain (which colors the background) and a simple stain to color the bacterial cell. The capsule appears as a colorless layer between the bacterium and the background.
Fibroblasts produce extracellular matrix for these connective tissue types?
Fibroblats produce extracellular matrix for these connective tissue types Which are they?
Why are encapsulated strains much more likely to cause disease than strains that do not produce a capsule?
Some bacterial cells are surrounded by an extracellular slime layer called a capsule or glycocalyx. This structure can play a protective role for certain pathogenic bacteria such as streptococcus pneunoniae. The capsule prevents phagocytic white blood cells from engulfing and destroying this bacterial pathogen, enabling the organism to invade the lungs and cause pneumonia. The capsule is also a means for many bacteria to attach to solid surfaces in the environment.
When conditions become unfavorable some bacteria produce a small internal resting cell called a capsule true or false?
false endospore
What Transgenic bacteria can be used to produce?
Genetically modified bacteria can be used to produce. This is a transgenic bacteria.
Does bacteria produce toxins?
Yes. Bacteria do produce toxins. Usually gram positive bacteria produce exo-toxins and gram negative bacteria produce endo-toxins.
What is Bowman's capsule?
The Bowman's capsule is also called the juxtaglomerular capsule and it is part of a nephron unit in the kidneys that helps the filtration process to produce urine.
Endocrine glands produce hormones which are secreted directly into the extracellular space?
interfictulal balance
What are the characteristics of a mutualistic relationship?
The term Mutualism, when referring to organisms and animals, is when both organisms benefit from each other. For example, certain fish feed off of a larger fish. This provides nnutrition for one fish, while the other gets a bath. Also, cows will benefit from certain types of bacteria, they benefit from the cellulose they produce, and the bacteria benefit from having nutrients in the host environment. I hope that helps!
What beneficial substance are produce by bacteria in the large intestine?
Bacteria in the large intestine can produce important vitamins for the body. For example, some bacteria produce vitamin K from eating fiber. Some bacteria also produce vitamin D.
