This laboratory experiment demonstrated the method used to identify different bacterial shapes. The manual provides background information on the three most common bacterial shapes before providing manual guidelines for the examination and identification of respective bacterial shapes. It begins with extensive insight into bacteria and their unique characteristics. Bacteria are stated to be “prokaryotic organisms, meaning that each is a singular cell which lacks a nucleus.” (Carolina, 2017, p.3) An in-depth discussion on the effects, role, and importance of bacteria reveal that bacteria are also known as pathogens. They are responsible for causing infectious diseases, including strep throat, gonorrhea, and Lyme disease. Therefore, it is important to have the necessary knowledge and skills to identify and classify different types of bacteria according to their shapes and arrangement.

The identification process was aided by the use of a microscope-one of the best ways of identifying bacteria, as recommended in the discussion section of the lab report is through their cell shapes. The study material for the experiment included readily available slides with embedded specimens hence eliminating the need for external sourcing. Through the microscopic lens, smeared cells were identified and documented in tables as recommended. The three identified included the bacillus, coccus, and spiral: Bacillus is a rod-shaped cell; coccus is a spherical cell, while spiral cells are shaped like coils. The findings are consistent with information available in the discussion section of the lab manual, which cites the existence of three common bacteria shapes and arrangements cocci, spirals, and bacilli (Carolina, 2017)
This experiment aids in the cell identification and classification process. This exercise is vital, especially in the medical sector, as it helps practitioners make an informed diagnosis of bacterial infections. Apart from medical use, bacteria identification is utilized when monitoring bacterial cultures in food production.
