This spirochete is not transmitted by air spores or a fomite. Humans may acquire the infection by direct. Acute infectious disease caused by the spirochete Leptospira interrogans which is transmitted in the urine of both wild and domestic animals.

An example of spirochetemia is caused by the spirochete Leptospira interrogans which gives rise to leptospirosis. Spirochaetales An order of bacteria in which the cells are slender spiral in shape and flexible and 5250μm long depending on species. Spirochetes are gram-negative motile spiral bacteria from 3 to 500 m 1 m 0001 mm long.

E the presence of two axial filaments each of which is anchored at one end. Spirochete spirochaete consists of gram-negative motile and spiral-shaped bacteria with endocellular flagella. Which of the following is a spirochete.

Oscillatoria is about 7 µm in. Which of the following is the spirochete that causes Lyme disease. Some bacteria have had a gene called Lac-Z put into their genomes so that when theyre fed a certain substance they pull the substance into their cells and cause it to turn blue.

The cytoplasm is surrounded by a cytoplasmic membrane and a peptidoglycan layer contributes to cell rigidity and shape. A spirochete B bacilli C spirilla D cocci. Spirochetes are unique in that they have endocellular flagella axial fibrils or axial filaments which number between 2 and more than 100 per organism depending upon the species.

Spirochaetes are slender unicellular helical or spiral rods Fig. Which of the following is the coccus that causes strep throat. Their movement is active and accomplished by spinning and flexing about the long axis.

B its ability to infect many wild and domestic animals. Individual bacteria can assume one of three basic shapes. 1-d They are obligate aerobes 2-b Treponema endemicum 3-b A screening test used for the detection of syphilis antibodies in the blood4-d Hard chancre 5-a Borrelia recurrentis 6-c Borrelia burgdorferi 7-d Used for the observation and detection of thin spirochetes suspended in a liquid 8-c Spirillum minor 9-c Giemsa stain 10- b Antibodies are.

Spherical cocci rod bacilli spiral spirilla comma vibrios or corkscrew spirochaetes. Their motility is due to periplasmic flagella ie. Examples of genera of spirochetes include Spirochaeta Treponema Borrelia and.
