Microbiological testing for unknown (salmonella sp.)

To begin my obscure research, I prepared and inoculated, with undiagnosed #24, 2 NA slants, 1 NA dental case and boiled and cooled 1 slant of FTM. I then placed the FTM, photographic plate (Quadrant streaked) and unitary of the slants into the incubator, and the other slant into the hood. The slants were inoculated using the glide inoculation technique. after 24 hrs I observe beaded, smooth and increase harvest-home in both slants. On the quad streaked plate I observe round colonies with raised margins and caterifrom elevations (Fig.1). The egress inside(a) the FTM slant was determined to be facultative. I labeled nonpareil the slants as reserve and placed in the cooler for come near use. At this term, I decided to do a identify of stains from the colony development. First stain that was conducted was the Gram stain, which determined that the unknown was Gram negative with rods (Fig.2). A gram stain of the growth observed in the working slant provided the sam e information. The secondly stain performed was a simple stain. This was done to verify the existence was, indeed rods. I also observed that there seemed to be a clear capsule around the organism. At this measure I preformed the capsule stain, which did indeed verify that the organism was encapsulated. During this time, I performed the cultural study with nutrient gel slant. The slant was observed for two weeks. Growth was seen along the stab line and on top of the medium, but the organism did not liquefy the gel. Furthermore, the personal credit line tests were performed: ·         PR Glucose: had residue at bottom of slant, broth turned yellow and ·         Lactose: little reside observed in tube no gas in shorthorn tube. ·         mannitol: Turned yellow >10% gas seen in shorthorn tube ·         Nitrate broth: Had become hazy no...
