Petri dish bacterial culture being placed in stack
MODEL RELEASED. Bacterial cultures. Gloved hand places a petri dish with a bacterial culture back onto a petri dish stack. These petri dishes are filled with different coloured agar nutrient media on which bacteria are grown. Lines of bacteria can be seen growing on the upper dishes where they were streaked. This involves running a platinum wire loop that has been placed in contact with a bacterial culture over the agar. By heating the loop, each successive set of streaked lines leaves fewer bacteria, until round colonies form around single bacteria. This technique is used to isolate particular strains of bacteria, which may then be incubated and grown in pure form

EDITORS COMMENTS
In this photo print, we witness a crucial step in the fascinating world of microbiology. A gloved hand delicately places a petri dish filled with a vibrant bacterial culture back onto a stack of similar dishes. Each dish is brimming with agar nutrient media, providing an ideal environment for bacteria to thrive and grow. Upon closer inspection, lines of bacteria can be observed on the upper dishes where they were streaked. This technique involves using a platinum wire loop that has been in contact with a bacterial culture. By carefully heating the loop, each subsequent set of streaked lines contains fewer bacteria until round colonies form around individual microorganisms. This meticulous process serves an important purpose - isolating specific strains of bacteria for further study. Once isolated, these strains can be incubated and grown in pure form, allowing researchers to delve deeper into their characteristics and potential applications in medicine or other fields. The image showcases the precision and expertise required in laboratory settings dedicated to microorganism research. It highlights the intricate nature of studying these tiny organisms that play such significant roles in our lives – both beneficial and harmful. With its vivid colors and attention to detail, this photograph captures not only scientific curiosity but also the dedication behind advancing our understanding of health care practices through microbiological exploration.
