THE 37° BACTERIAL COUNT

Effect of olive leaf powder on the performance and ileal bacterial count of broilers

This experiment was conducted to investigate the effects of olive leaf (OL) on the performance, abdominal fat pad and some ileal bacterial population of Cobb broiler chickens. A total number of 400 day-old chicks were randomly distributed into floor pens and reared under the same condition until 14 days of age. On day 14, each pen was randomly assigned to one of the five experimental treatments...

Computational Approach to Count Bacterial Colonies

Research involving bacterial pathogens often requires enumeration of bacteria colonies. Bacterial colony enumeration is an essential tool for many widely used biomedical assays. Bacterial colony enumerating is a low throughput, time consuming and labor intensive process. Since there might exist hundreds or thousands of colonies on a Petri dish, and the counting process is often manually perform...

Polymorphonuclear leukocyte count in spontaneous bacterial peritonitis.

Human host defense peptide LL-37 prevents bacterial biofilm formation.

The ability to form biofilms is a critical factor in chronic infections by Pseudomonas aeruginosa and has made this bacterium a model organism with respect to biofilm formation. This study describes a new, previously unrecognized role for the human cationic host defense peptide LL-37. In addition to its key role in modulating the innate immune response and weak antimicrobial activity, LL-37 pot...

Metabolic activity of bacterial cells enumerated by direct viable count.

The direct viable count (DVC) method was modified by incorporating radiolabeled substrates in microautoradiographic analyses to assess bacterial survival in controlled laboratory microcosms. The DVC method, which permits enumeration of culturable and nonculturable cells, discriminates those cells that are responsive to added nutrients but in which division is inhibited by the addition of nalidi...
