Introduction:
Salmonella, a genus of gram-negative, rod-shaped, cytochrome oxidase-negative, lactose-negative, non-sporulating bacteria that is the etiological agent of Salmonella gastroenteritis or salmonellosis.
Case summary:
A person (31-year old-male) became feverish 4 days after arriving at a vacation resort in Idaho. During his stay he ate at two restaurants that were not associated with the resort. At the resort he drank soft drinks with ice, used the hot tub, and went fishing. The resort is supplied by a well that was dug 3 years ago. He went to the hospital when he developed vomiting and bloody diarrhea. Gram-negative, lactose-negative bacteria were cultured from the stool sample. The patient recovered after receiving intravenous fluids.
Characters of the case:
- A patient (Male) – 31 years old
- Vomiting and bloody diarrhea
- Gram-negative, lactose-negative bacteria
- Pathogen cultures from stool sample

Microbiology: An Introduction
- Gram positive case on the first day back to class at the local university, a student noticed a small abscess on his right elbow but didn't think much about it. Over the next couple days, however the abscess became more swollen and painful. The student decided to visit the health centet he told the doctor it looked like a spider bite but didn't recall being bitten. The doctor took a swab of the lesion and prescribed an antibiotic cream as it looked infected. The swab was sent to the lab for testing within a few days of treatment, the student lesion was healed. what is the overview of the etiological agent?( including basic characteristics of the organism, diseases it cause and use in industry) Broad to get a sense of what this organism isarrow_forwardThis 35-year-old woman reported that she had experienced three bouts of urticaria of unknown origin about 10 years ago. The urticaria affected her mucous membranes and skin. She had experienced similar symptoms after repair of a fractured femur caused by a skiing accident. These symptoms were attributed to an antibiotic reaction. As an emergency room nurse, she observed occasional localized hives after the use of latex gloves. Even when she used hypoallergenic latex gloves, she continued to have hives every few months. Increased urticaria, at times generalized, continued to occur. Within 30 minutes of having a routine vaginal examination performed by a health care provider wearing latex gloves, she had an anaphylactic reaction that required resuscitation and hospitalization. A vaginal biopsy 1 week later required a latex-free environment for her safety. A short time later, she was forced to retire from nursing because of symptoms of asthma. She had also developed food allergies to…arrow_forwardThree to five days after eating Thanksgiving dinner at a restaurant, 112 people developed fever and gastroenteritis. The dinner consisted of Roast Turkey, turkey giblet soup, mashed potatoes and crushed giblet gravy. The gravy was not refrigerated and was served the entire Thanksgiving day. The analysis of leftover food showed the same bacteria as was isolated from patients. a) What was the source of illness? b) What was the most likely microbe causing this illness? c) Was this an infection or an intoxication?arrow_forward

The baby was having trouble nursing/breastfeeding and the parents noticed milk would "dribble" out of the babies mouth. The baby had an apparent white coating inside the mouth. Since the baby's birth, the mother explained she would place honey on her breast to encourage the baby to nurse. You notice the baby has little muscle control, appearing like a "rag doll", exhibiting flaccid paralysis.

Parents report that the lesions developed over the course of a week. On physical examination, his temperature is 37°C, pulse rate is 80/min, blood pressure is 110/80 mmHg, and respiratory rate is 20/min. A culture of the sample from the lesion yields Gram-positive, catalase-negative, cocci. Which of the following is the most likely pathogen?
