A streak culture was performed on a Tryptic Soy Agar Plate for isolation and purity and then incubated at 37 degrees Celsius for 24 hours. A gram stain was performed to determine whether the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed

In her article entitled “Close Encounters of the Prehistoric Kind”‚ Science Magazine correspondent Ann Gibbons explains that due to interbreeding between Neanderthals and early modern humans‚ modern humans still contain traces of prehistoric Neanderthal DNA. According to researchers‚ Asians and Europeans most likely possess a higher frequency of Neanderthal genomes than Africans because the two species “occupied the [same regions] intermittently” in Europe‚ the Midwest‚ the Near East‚ and Russia

most important soft tissue feature helpful in evaluating the dental–facial composition and establishing a smile design is Lip analysis” (299). To understand lip analysis thoroughly‚ one needs to understand the lip mobility and lip morphology‚ states Davis. Lip morphology breaks down into “width‚ fullness‚ and symmetry of the lip” (Davis 300). Davis states‚ “wide lips make for a wide smile. In general terms‚ a smile that is at least half the width of the face‚ at that level of the face‚ is considered

while in the laboratory it has been found that birds can be infected‚ as well as cell cultures from mammals‚ birds‚ reptiles and insects (Carter and Saunders 175). The rabies virus is an enveloped virus in the Rhabdoviridae family with a cylindrical morphology. The structure of this virus is unique. It is a rod or bullet shaped‚ single-stranded‚ genome with negative-sense‚ unsegmented‚ enveloped RNA virus (Fig. A). The genetic data is packaged as a ribonucleoprotein complex in which RNA is tightly bound

The first procedure that needed to be done was to streak the unknown out on a Trypticase Soy Agar plate‚ using the T streak method. This needed to be done in order to test the purity of the unknown. After the plates were incubated and grown‚ the morphology was observed and recorded and a Gram stain was performed. After determining the Gram reaction‚ specific biochemical tests were performed. The biochemical tests were chosen from the unknown identification tables that were in the lab manual. Since
