Question

A. Case 1b: Safari Expedition Steve and his wife Stacey decided to celebrate their 10th wedding anniversary by traveling to Africa to go on Safari. Their tour guide, told them about a waterfall that was off the beaten path in an uninhabited part of Africa. It would take about an hour to get there. Intrigued, Steve and Stacey decided since there were here, they might as well experience everything they could However, that morning prior to departing on the safari, Steve forgot to put on bug repellent. The following day, Steve noticed a bite mark on his arm. It was a little sore and contained some dead tissue. A few days later, they departed for the United States. Once home, Steve became ill with headaches and a fever. He decided to go to the hospital where you work. 1. You are concerned about Steve and a potential illness given his recent travel plans. You decided to take a blood sample and you detect a microbe with 60s/40s ribosomes, Based on this initial analysis, identify what type(s) of microbe(s) could be causing the infection (Gram + bacteria, Gram - bacteria, protozoan, virus, or yeast)? 2. Further analysis shows the presence of a long, thin microbe that has a single, long flagellum. Explain which group of protozoans this belongs to and contrast to other groups of protozoans (in other words, list how they are different).

Explanation / Answer

ANSWER 1)
Based on the Ribosome subunit, the microbe is a protozoa.

EXPLANATION-
60s/40s ribosome stand for a 80s ribosome. 80s ribosome are a chracteristic feature of Eukaryotes. Protozoans are nothing but single-celled Eukaryotes. Thus it can be concluded that the microbe is a protozoan.
Bacterias that is prokaryotes have a 50s/30s that is 70s ribosomes, while virus are non cellular entities hence lack ribosomes.

ANSWER 8)
The presence of single long flagellum proves that the microbe is a Flagellated protozoa, probably of the subphylum mastigophora . It is generally is non photosynthetic and free living pathogenic organism example Trypanosoma Gambiense which causes Sleeping Sickness.
Other types of Protzoans include,
Ciliates, which move by using hair like structures on their body called cilia.
Amoebae, which move by feet like structures called pseudipodia.
Sessile, which do no move at all.
