Gradient Plate for Hicomb Minimum Inhibitory Concentration (MIC) Test

Abstract Background and objectives: "The comb antibiotic sensitivity test" is a quick, reliable and cost effective method to determine the susceptibility of bacteria to different antibiotics. The purpose of this study is to design a plate that is easy and quick to use, and enable to be interpreted easily without the need for measurement of the margins with a ruler. Material and Method...

Disc antibiogram test with graded plate method

Abstract Background and objectives: Halo interference around antibiogram disc is one of the problems seen in Agar media. This study aimed at applying graded plate method to reduce this problem. Material and Methods: Forty-eight millimeter plates, before putting disc, were graded and the location of discs was determined. Instead of full disc, we used half-disc and then compared the haloe interfe...

Contributions for standardisation of plate loading test

The static loading plate tests have been done in different engineering works and particularly in earthwork quality control. At Portugal AFNOR NF P94-117-1 and DIN 18134 standards are frequently used for this purpose. These standards differ on the test protocol and on test interpretation, which reflects on the final elastic modulus obtained. Attempting the importance that this parameter assumes ...

The plate virulence test for diphtheria.

A method has recently been described (Elek, 1948) for the detection in vitro of toxin-producing organisms including C. diphtheriae. The present paper has two purposes. The first is the examination of a larger series of strains of C. diphtheriae with a view to establishing the reliability of the procedure, for if the method is to be of any practical value for clinical purposes it must demonstrat...
