Demand that they be multiplied‚ that they be adorned. These are the temples of the future—temples of well-being and of happiness. There it is that humanity grows greater‚ stronger‚ better.

Inocula were obtained from overnight fresh cultures adjusted to approximately log 108 CFU/ml‚ a turbidity equivalent to a 0.5 McFarland standard (Kroning et al.‚ 2016). The inocula were spread on the surface of Mueller-Hinton agar (MHA) plates. The disk diffusion test‚ recommended by the Clinical and Laboratory Standards Institute (CLSI‚

What Sunscreen really works? Problem: Will sunscreen with an SPF of 4 be able to withstand the sunlight more effectively than SPF 45? Purpose: Due to the increasing amount of sun exposure on teens‚ we want to ensure that sunscreen can protect against the sun. An increase amount of exposure can damage the skin directly. The dangers of increased sun can lead to the 3 types of skin cancer (Basal‚ Melanoma‚ and Squamous) and these types can spread to other parts of the body. The most dangerous form

Blood agar plate This test is used to detect the hemolytic activity in the bacteria. A darkish green color on the media around the bacteria would represent incomplete hemolysis. A transparent media around the bacteria colony represents complete lysis of the red blood cells. If no change is observed around the bacteria colony then the bacteria is non-hemolytic. For my bacteria no change is observed in the media therefore the bacteria is non-hemolytic and negative result. MacConkey Agar test

of bacteria in a given cultured sample is too great to be counted directly. The samples will be serially diluted by a factor of 10 in sterile saline‚ to be repeated 7 times. A 10 microliter aliquot from each dilution will be placed on a 5% blood agar plate or a MacConkey plate‚ depending on the type of organisms plated. These plates are selected because of the ease of differentiation between organisms. The original vial and all diluted aliquots will then be refrigerated to restrict growth until

technique). Each group will inoculate his/her own plate of Mueller-Hinton agar with an assigned culture. To that inoculated plate‚ you will then aseptically add sterile filter paper discs (using a disc dispenser)‚ which contain a known concentration of antibiotics. As soon as the antibiotic discs touch the agar‚ the antibiotic will begin to diffuse into the surrounding agar. During incubation the bacteria you inoculated onto the agar

This is a quantitative test and is considered to be the gold-standard method for biofilm detection (13). Organisms isolated from fresh agar plates were inoculated in 10 mL of trypticase soy broth with 1% glucose. Broths were incubated at 370C for 24 hours. The cultures were then diluted 1:100 with fresh medium. Individual wells of sterile 96 well-flat bottom polystyrene tissue culture
