C. Trachomatis

Protist lab report
WHAT FUNGUS OR PROTIST IS THIS?
Chlamydia Trachomatis is one of 3 species of the genus Chlamydia and has 3 variant prokaryotic strains.
HOW DO THEY AFFECT HUMANS AND WHY DO WE CARE?
Chlamydia is the most common sexually transmitted disease in the world. It is estimated that there were 92,000,000 new cases reported in 2009. The 3 strains of c. Trachamotis are trachoma which affects the eyes, urethritis which affects the urethra and cervix and lymphogranuloma venereum, which affects the human lymph system. It causes numerous diseases including prostatitis, epiditimytisis, proctitis and infertility in males and cervicitis, pelvic inflammatory disease, chronic pelvic pain, ectopic pregnancies and infertility in women. It can also cause eye infections in men and women which can lead to blindness. It can also be passed from mom to baby during birth in the form of eye infections and pneumonia.
HOW WAS IT DISCOVERED?
c. Trachamotis was first discovered in 1907 by Giemsa staining by Halberstaedter and von Prowazek who took scrapings from individuals infected with trachoma and inoculated orangutans eyes with the samples. This demonstrated how the disease could be spread between infected individuals. In 1929, there was an epidemic of pneumonia originating from contact with Chlamydia infected parrots. In 1935, Chlamydia was thought to be a virus because it could only exist in living cells. In the 1960’s Chlamydia was confirmed to be a bacteria, when it was discovered that it contained both DNA and RNA, ribosomes, and cell walls which are structures typical of bacteria.
HOW WAS IT NAMED?
Chlamydia is named after the Greek word chlamys meaning "cloak draped around the shoulder". This is used as a description for the inclusions of the bacteria that surround the nuclei of infected cells.
HOW DO WE DIFFERENTIATE THIS PROTIST FROM OTHERS?
c. Trachamotis is an aerobic, obligate intracellular
