Concept explainers
To determine:
The chemical produced by the organism in the following illustration.
Concept introduction:
The illustration depicts the growth of bacteria on blood agar medium. Blood agar media is included under complex media as it has soybean meal and casein. This media also exhibits differential growth of microorganisms on a single media and brings major differences in different colonies; hence it is also a type of differential media. Microbes produce different types of toxins which are associated with causing diseases.
To determine:
The process by which this chemical add pathogenicity to an organism.
Concept introduction:
The illustration depicts the growth of bacteria on blood agar medium. Blood agar media is included under complex media as it has soybean meal and casein. This media also exhibits differential growth of microorganisms on a single media. The medium is used to grow a wide spectrum of microbes. The medium includes a mixture of nutrients which supports the growth of microorganisms.

Your project manager gives you your next assignment, as you look down the list of organisms that you will be performing susceptibility tests, your eyes stop on Bacillus subtilis and Bacillus anthrax. 1) What gave you pause about these bacteria? 2) What conversation do you need to have with your project manager? no references, just homeworkarrow_forwardPlease reply to the post below whether or not you agree or disagree and why A common microbe found in foods and can be taken orally are probiotics. Probiotics are live bacteria that balance good and bad intestinal bacteria and aid in digestion or digestive problems. For example, Lactobacillus species habituate where rich carbohydrate substances are available including the human digestive and urinary tracts. In 1900 lactobacillus acidophilus was isolated by Moro from infant feces and the intestinal tract of animals and humans. Also, it was reported in the feces of milk fed infants and older persons consuming high milk/lactose diets. This microbe is also found in plant materials and agricultural products particularly milk, cheese, fermented milk products and beverages such as wine and cider. Historically, Lactobacillus species is most often known to be capable of eliciting beneficial effects on the microbiota of the gastrointestinal tract. It helps the body break down food, absorb…arrow_forwardPathogen Staphylococcal Infections Streptococcal Infections Pneumonia Infections Bacterial Meningitis: Haemophiles influenzae OGI Tract Infections - Escherichia coli Common Cold Influenza English (United States) Type (Bacteria, Virus, Fungus, or Parasite) Text Predictions: On Signs and Symptoms Accessibility: Investigate Search One Interesting Fact / Statistic of Disease W D Focusarrow_forward
