Question

Questions 1. What type of pathogen is Candide glabrata? C. Viral a. Bacterial d. Parasitic b. Fungal What area(s) of the body are commonly colonized by C. glabrata? 3. What type of pathogen is Burkholderia cepacia? c. Viral a. Bacterial b. Fungal d. Parasitic 4. What is usual source/habitat of B. cepacia? is an opportunistic pathogen? pathogens in the family Enterobacteriaceae from the stool. 6. List 3 selective media that are used to isolate 7. What medium is specifically designed to isolate C, difficile from the stool? 8. Oxacillin sensitive Staphylococcus s aureus was isolated from the blood of this patient. What is the drug of choice to treat methicillin-resistant S. aureus (MRSA)? The material excised from the terminal ileum was stained and a small section sent to the parasitology section of the laboratory. The section sent to the parasitology section of the lab was placed in a drop of sterile saline and the tissue was teased apart with dissecting needles and examined under the microscope Motile amoebae were seen which exhibited directional motility and the extrusion of long, finger-like pseudopodia with finely granular endoplasm and hyaline ectoplasm. In the stained tissue sections (Figure 3) the organisms exhibited a single nucleus with peripheral chromatin that was uniform and small in size and which was evenly distributed. The karyosome was centrally located, small, round, and compact. The 9. cytoplasm was finely granular and some trophozoites had ingested red blood cells. No cyst forms were found in the tissues. This organism is most likely - a. Entamoeba histolytica b. E. hartmanni c. E. coli d. E. dispar How could you differentiate the trophozoite stage of the pathogenic species from trophozoites of the other non-pathogenic (commensal) amoeba in the genus Entamoeba commonly found in the colon? .

Answer 1

1.fungi.it is the species of haploid yeast.yeasts are fungi

2.gastrointestinal tract and mouth are the area commonly effected with this fungi

3.bacteria.it is mainly seen in cystic fibrosis patient as virulent pathogen

4.water,soil and plants are the habitat of B.cepacia

5.it is a infectious pathogen which cannot harm its host but it is able to develop disease when the resistance of the host is less

6.endo agar,deoxycholate agar,XLD agar

7.cefoxitin is one of the media used to isolate C.difficille

8.vancomycin is the drug of choice .it is highly infectious thus highly effective antibiotic is used .

9.answer is A.these features can be seen in amoebizoa.

10.tropozoite pathogens occurs due to the indigestion of water food in intestinal tract.non pathogens passed through stool .
