Myocarditis
Published in Mary N. Sheppard, Practical Cardiovascular Pathology, 2022
Rarely, myocarditis has been found in Salmonella septicaemia caused by Salmonella typhi or paratyphi. Yersiniosis myocarditis is, in most cases, a mild disease and considered to be immune in pathogenesis. Mycoplasma pneumoniae infection is commonly accompanied by mild myocarditis with up to 33% of cases exhibiting ECG changes.
Laboratory Diagnostic Tests in the Evaluation of Fever
Published in Benedict Isaac, Serge Kernbaum, Michael Burke, Unexplained Fever, 2019
Although diarrhea is rare in typhoid fever, stool examination may reveal large numbers of mononuclear cells on direct smear. The stool culture in typhoid is generally negative until the 10th to 14th day of illness. Unusual infections of the ileocecal region such as yersiniosis and intestinal tuberculosis may be diagnosed through culture of stool on specialized media.

Yersiniosis is usually a self-limiting illness and mortality is extremely rare (1.2%) (Long et al. 2010). However, antibiotics are indicated in severe infections and patients who are immunocompromised. The preferred antibiotics are fluoroquinolones for adults and septran for children for a period of 5 days. In areas where Yersinia is resistant to fluoroquinolones, the alternative choice is septran or doxycycline. In septicemia and more severe infections, a combination of third-generation cephalosporin along with an aminoglycoside is preferred, and the duration of treatment is for 3 weeks. Because Yersinia is almost foodborne (90%), proper cooking of the meat, adequate pasteurization of milk, and drinking safe water can prevent such infections.
Protein-losing enteropathy caused by Yersinia enterocolitica colitis

Y. enterocolitica can be transmitted via water, soil, animals and food. Human major pathogenic serogroups are O:3, O:5,27, O:8 and O:9 [7]. Raw pork products such as neck trimmings, tonsillar tissue, tongue and tripe are important sources of yersinioses [8–10] which can present as abdominal pain, loose, watery or bloody stools, fever and septicaemia [8,11,12]. Y. enterocolitica adheres to gut epithelial cells and invades them via invasin and other surface proteins such as yersinia outer membrane proteins (Yops). It then localises in lymphoid tissue within the gut wall and in mesenteric lymph nodes [7,13]. Yersiniosis is commonly diagnosed by positive stool culture and it can also be isolated in culture from mesenteric lymph nodes, pharyngeal exudates, peritoneal fluid or blood. Serology or Western blotting, which uses Yops as antigens for antibody detection is more sensitive and specific than stool culture or other serological methods of diagnosing yersinia-associated complications [12,13].
Resistome and microbial profiling of pediatric patient’s gut infected with multidrug-resistant diarrhoeagenic Enterobacteriaceae using next-generation sequencing; the first study from Pakistan

The predominance of Bifidobacteriaceae associated non-pathogenic bacterial species in healthy controls reflects their intact gut microbiota while the abundance of Enterobacteriacea associated opportunistic pathogens in MDR microbes infected patients indicates the association of AMR with gut microbial dysbiosis. Our results are supported by a previous study indicating that diarrhea and various doses of antibiotics increase the likelihood of children’s gut microbiota enrichment with MDR bacteria in children [29]. The various gram-negative bacteria identified in the gut microbiota of MDR infected patients in the present study have been reported to be the potential causative agents of diarrhea in children [30]. Bacterial species belonging to the genus Yersinia and Klebsiella identified in the gut microbiota of MDR diarrheagenic Enterobacteriaceae infected patients have been associated with severe diarrheal diseases such as yersiniosis [31].

Yersiniosis is an important foodborne disease related to the consumption of raw or undercooked pork, which may be primarily contaminated by contact with equipment and utensils (Kasprzak 2014). Jun et al. (2018) evaluated the effectiveness of phage in controlling Yersinia enterocolitica in raw minced pork, ready-to-eat barbecued pork loin, and utensils (cutting boards and knives). Phage treatment applied to food after bacterial contamination decreased counts by one to three logs. In addition, phage treatment of kitchen utensils was also effective in decreasing the bacterial population by one to two logs from the original level.
