Outbreak of Human Trichinellosis - Arizona, Minnesota, and South Dakota, 2022.

Trichinellosis is a parasitic zoonotic disease transmitted through the consumption of meat from animals infected with Trichinella spp. nematodes. In North America, human trichinellosis is rare and is most commonly acquired through consumption of wild game meat. In July 2022, a hospitalized patient with suspected trichinellosis was reported to the Minnesota Department of Health. One week before symptom onset, the patient and eight other persons shared a meal that included bear meat that had been frozen for 45 days before being grilled and served rare with vegetables that had been cooked with the meat. Investigation identified six trichinellosis cases, including two in persons who consumed only the vegetables. Motile Trichinella larvae were found in remaining bear meat that had been frozen for >15 weeks. Molecular testing identified larvae from the bear meat as Trichinella nativa, a freeze-resistant species. Persons who consume meat from wild game animals should be aware that that adequate cooking is the only reliable way to kill Trichinella parasites and that infected meat can cross-contaminate other foods.

Acute Cholecystitis Complicated with Gallbladder Perforation and Peritonitis Caused by Vancomycin-resistant Lactobacillus paracasei.

A 66-year-old female has a medical history of remote subarachnoid hemorrhage and dysphagia. She presented with acute onset of right upper quadrant abdominal pain. Ultrasound showed acute cholecystitis, and subsequent CT scan of the abdomen and pelvis showed gallbladder perforation. The patient's hospital course was complicated with peritonitis, and bile culture grew vancomycin-resistant Lactobacillus paracasei. This case report will focus on an unusual case, in which Lactobacillus acts as the primary pathogen in peritonitis secondary to an cholecystitis-induced gallbladder perforation. There are four other case reports worldwide that illustrate Lactobacillus species as the primary pathogen in cholecystitis, only one of which was complicated with peritonitis.
