ascertain and identify major bacterial contaminants of frozen fish‚ which hitherto had constituted an important dietary intake of the people of Nsukka‚ Nigeria. Fish samples collected were identified and bacterial load of the samples determined using agar plate method. Differentiations and characterizations of various isolates were based on biochemical reactions and gram-staining technique. Frozen mackerel fish (Scomber scombrus) was used for the study. Invitro assay result revealed that the samples were

IDENTIFYING GRAM POSITIVE COCCI As mentioned in Exercise 8‚ “Identifying Gram Negative Rods”‚ identifying bacteria is a common activity in the microbiology lab. Like the game Clue™‚ each time you gather a piece of information to solve the mystery‚ you gather some information that supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus

It is very critical in microbiology to determine the effectiveness of a chemical to either inhibit or kill an organism as it can help cure a disease. If the agent kills the bacteria‚ it is called bactericidal. If the agent inhibits the growth of bacteria‚ it is called bateriostatic. (Fundaments of Microbiology Lab Manual) The purpose of this experiment was to examine the effect different disinfectants and antiseptics‚ which are used to decrease the number of microbes‚ on Escherichia coli and Staphylococcus

swab containing the inoculum was introduced to the media‚ and using a nichrome inoculating loop‚ the inoculum was streaked using the clock method. The clock method was performed by drawing four different quadrants or sectors on the back-side of the plate containing the culture medium. The four quadrants were drawn in such a way that at the last two lines of every sector there is small portion termed as a tail [2] that is the actual starting point of the next sector. Streaking is performed from the
