Yersinia pseudotuberculosis infections in two bacteriologically confirmed cases are described. A child was found to have mesenteric adenitis and an adult had septicemia. Invariably simulating acute appendicitis, mesenteric adenitis most often occurs in male children and adolescents. Septicemia with this organism usually affects elderly, debilitated patients, who frequently have chronic hepatic disease. The infrequent diagnosis of infection with Yersinia pseudotuberculosis in the United States is probably due to failure to consider it a human pathogen. Currently classified with the Enterobacteriaceae, Yersinia pseudotuberculosis in a non-lactose-fermenting, Gram-negative coccobacillus. It is sensitive to a wide range of antibiotics, including tetracycline and streptomycin, but usually is resistant to ampicillin. Yersinia pseudotuberculosis has a worldwide distribution in wild and domestic mammals and birds. Infections in man may result from direct contact with infected animals or their excreta.

In 352 patients who were hospitalized with symptoms of an acute appendicitis, Yersinia infection were determined in 18.2% of the cases by cultural and serological methods. Infections due to Y. enterocolitica (Y. e.) serovar 0:3 were approximately 6 times more frequent than those due to Y. e. serovar 0:9. Yersinia pseudotuberculosis (Y. pstbc.) could only be isolated in one patient from a mesenterial lymph node. In another case Yersinia serovar 0:6 could be isolated as well as Y. e. serovar 0:3. The majority of the infections were found in the age group 9-12 years. The incidence was highest in the summer months June-August.

Infections and their complications requiring surgical intervention are a frequent presentation in African children. Surgical site infection (SSI) is common with rates over 20%, even after clean procedures. The high rates of SSI are due in part to lack of infection control and surveillance policies in most hospitals in Africa. SSI is attended by complications, long hospital stay, and some mortality, but the economic consequences are unestimated. Typhoid fever and typhoid intestinal perforation are major problems with perforation rates of approximately 10%, which is higher in older children. The ideal surgical treatment is arguable, but simple closure and segmental resection are the present effective surgical options. Because of delayed presentation, complications after surgical treatment are high with a mortality approaching 41% in some parts of Africa. Nutrition for these patients remains a challenge. Acute appendicitis, although not as common in African children, often presents rather late with up to 50% of children presenting with perforation and other complications, and mortality is approximately 4% is some settings. Pyomyositis and necrotizing fasciitis are the more common serious soft-tissue infections, but early recognition and prompt treatment should minimize the occasional mortality. Though common in Africa, the exact impact of human immunodeficiency virus infection on the spectrum and severity of surgical infection in African children is not clear, but it may well worsen the course of infection in these patients.

Infections caused by foodborne enteric pathogens including typhoidal and non-typhoidal Salmonella species can mimic symptoms of acute appendicitis. The association between such bacterial pathogens and pathology-proven acute appendicitis has been described, but this link is poorly understood. Here we describe a case of a young man with typhoid fever presenting with histology-proven acute appendicitis requiring urgent appendectomy, and provide a brief review of relevant literature to prompt more widespread recognition of this rare cause of a common surgical emergency.
