These antibodies, if present in the serum, will agglutinate bacterial suspension which carries homologous antigens. If agglutination occurs with O antigen then it is considered positive for Salmonella typhi. If agglutination occurs in A or B antigen then it is confirmed as positive for Salmonella paratyphi. Agglutination will occur in H antigen for all the cases of antigens like O, A, and B. This Widal test can be performed either by slide agglutination test or by tube agglutination test.…

However Philpott also leaves out some key info that makes his prior points not match up. His argument seems partly…

bacteria cell meaning that it is bacteria. [Plus, it’s got it in its name ;)] 2.) Salmonella-I knew this was Salmonella because it was rod-shaped gram-negative bacteria. Gram-negative bacteria do not retain the crystal violet dye used in the gram staining method due to the fact that they have cell walls that are thin. Gram-negative bacteria are often harmful to a host, which is the case for many of the Salmonella bacteria. Protists 1.) Irish Moss- I knew that this was Irish Moss because it…
