Questions. Worldwide. What areas of the world have the highest incidence of parasitic infections? What are the top three parasites worldwide? Are the same parasites in the most affected areas? Or would it be better to have a a top three parasites be in each region? United States. What areas of the United States have the highest incidence of parasitic infections? What are our top three parasites? Are these the same as other areas of the world? Are they similar? What are the symptoms/treatments? California/Central Valley How about here? What are the top three animal parasites in the central valley? Are there any other parasites that are not animal that are important here? More. Comparing these two phyla, Platyhelminthes and Nematoda. Which causes more problems? Which phyla is the parasitic infection of greater import the human infected? Which phyla(s) is/are the most important intermediate host? What would be some of ways of limiting parasitic infections?

28. Diseases such as diarrhea; dysentery, porkworm infection have mode of transmission. 29. Human reservoir are primary reservoir for STDs and transmitted by direct contact mode 30. If minimal # of cases per year for a disease in a country is 1000, it is called as level; but if # of cases in specific month reach 10,000; it will be called as 31. Incubation period: the initial phase of a disease during which no signs and symptoms appear even if person is infected. 32: illness: classical phase of disease when all signs and symptoms are seen. 33. Prodromal period: phase during which mild general symptoms are felt by patient. 34. Convalescence: recovery period of a disease. 35. Decline: period after antibiotic treatment in which microbial number decreases and signs and symptoms subside. 36. Carrier: asymptomatic person infected with pathogen is called. 37. Needles; dollar bill; door knob etc. are examples of fomites and air, water, food; soil are examples of nonliving reservoir 38. Fever; hypotension; rash are sign of a disease; while headache; weakness; nausea; fatigue are examples of symptom of a disease. 39. sporadic: small; infrequent number of cases of a disease occur in a population is called. 40. hospital acquired infections are: nosocomial infection Fill in the blanks: Nosocomial infections 41. Three factors in cause of nosocomial infections are: ; and . 42. Two categories of microbes that cause nosocomial infections are:

Name the type of organisms and the scientific name of the following gastrointestinal tract diseases. Name of the disease | Type of organism (bacteria/virus/fungi/protozoa/helminths) | Scientific name of the organism causing the disease. 1. Mums 2. Hepatitis 3. Giardiasis 4. Cholera 5. Amoeboid dysentery 6. Schistosomiasis 2. a. Compare the causal agents of Hepatitis A, B, & C. Hepatitis A: Hepatitis B: Hepatitis C: b. Which hepatitis viruses may establish chronic infections? Ans: 3. What feature(s) is/are common to diseases caused by Campylobacter, Shigella, Escherichia, Salmonella, and Listeria species? Ans:
More than 100 bacterial species live on the surface of the human body. Bacteria cover portions of human skin in concentrations of up to 8 million cells per square centimeter. In particular, human sebaceous glands support the growth of the bacterium Propionibacterium acnes, which uses oil from the glands for food. Two strains of P. acnes are associated with the development of acne on human skin, but other strains are associated with healthy skin. Which statement best describes the relationship between humans and P. acnes? a. In some cases it is commensal and in others it is parasitic. b. In some cases it is mutualistic and in others it is commensalistic. c. It is almost always parasitic. d. It is almost always mutualistic.
