There was revealed a regular reduction of plague, tularemia and pseudotuberculosis bacteria count in the lungs of guinea pigs the first 12 hours after aerosol infection. Generalization of the infectious process and associated septicemia occurred in pulmonary plague and pulmonary tularemia on the 1st-2nd day, and in pulmonary pseudotuberculosis - on the 4th-5th day. Limits of accumulation of the causative agents in the organs and the blood at various stages of the infectious process were established.

An increase of the ingestive and digestive capacity of neutrophils to the homologous causative agent and tularemia microbe was revealed by the opsonophagocytic test in Microtus arvalis, albino mice and guinea pigs infected with sublethal Yersinia pseudotuberculosis and Salmonella typhimurium doses. In subsequent tularemia infection some of the animals displayed a reduction of the septicemia intensity, prolongation of the disease and elevation of the susceptibility threshold. Period of manifestation of the inhibitory action on tularemia coincided with that of the increase in phagocytic activity

The clinical symptoms of infections with Y. ent. and pseudotub. are of a different nature. Whether the infection becomes apparent in form of a pseudo-appendicitis, enterocolitis or a typho-septic disease does apparently not only depend on the type of pathogens but also on the children's condition with regard to their resistance. All forms mentioned are observed in case of infections with Yersinia pseudotuberculosis as well as in case of infections with Yersinia pseudotuberculosis as well as in case of infections with Yersinia enterocolitica. However, infections with Yersinia enterocolitica seem to have more frequently a chronic course and to be accompanied by conjunctivitis, arthritis and skin diseases. For the subacute and the chronic forms of the disease, a specific treatment is not necessary in most cases. Severe enterocolitis and septicemia, however, need an antibiotic therapy besides the symptomatic therapy. The best antibiotics for an infection with Yersinia enterocolitica still seem to be the tetracyclines and leucomycine, for an infection with Yersinia pseudotuberculosis also the cephalosporines, ampicilline and carbenicilline.

The authors discuss the clinical and bacterial characteristics and progressive changes occurring in Yersinia pseudotuberculosis septicemia, basing their observations on one personal case and 30 adult cases reported in the published literature. The roles played by a generally poor condition of the patient and martial overloading are emphasized, and the changes brought about by the introduction of antibiotic therapy evaluated.

Human infection by Malassez and Vignal's bacillus (Yersinia pseudotuberculosis) can take many clinical aspects, the most frequent of which is mesenteric adenitis with pseudoappendicular syndrome, but occasionally also appearing as a tumor of the right lower abdominal quadrant. In a subsequent stage this mesenteric adenitis is often accompanied by erythema nodosum. There also exist some septicemia-like forms, which have become more and more frequent of late, always appearing on a particular terrain (predisposed persons). These various forms all correspond to contamination via the digestive route. Other, more exceptional modes of contamination may result in much rarer forms, such as ocular or pulmonary forms. Diagnosis is based on: (a) demonstrating the presence of Yersinia pseudotuberculosis, (b) serodiagnosis, (c) a positive intradermal reaction, (d) the characteristic aspect of lymph node lesions. Pseudotuberculosis is extremely frequent in animals. Many species, most of them rodents or birds, can serve as healthy carriers. This is how cats, through their access to this natural "reservoir", get contaminated and thus act as a "conveyor belt" in transmitting the disease to man.

Yersinia pseudotuberculosis septicemia and postdiarrheal hemolytic-uremia syndrome (HUS) developed in a 15-month-old boy after he ingested unpasteurized goat's milk. The epidemiology of this organism and the disease states caused by it are discussed with the suggestion that an association between it and some cases of the HUS might be found if sought.

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.

Septicaemia caused by Y. pseudotuberculosis in a female patient, aged 61, is reported. The patient suffered from amyloidosis with extensive infiltration of liver, spleen, and kidneys. While under treatment with corticosteroids and azathioprin, Y. pseudotuberculasis, serotype IA, was isolated from each of 6 blood cultures. The infection responded favourably to treatment with ampicillin. The development of Y. pseudotuberculosis septicaemia owing to impairment of the defence mechanisms by the underlying disease and the treatment given is discussed.

Virulent strains of Yersinia enterocolitica cause disease syndromes ranging from mild gastroenteritis to lymphadenitis and septicemia. The ability of these bacteria to invade intestinal epithelial cells to gain access to the reticuloendothelial system is thought to be an important aspect of their virulence. We report here on the cloning of two Y. enterocolitica chromosomal loci, inv and ail, each of which confers an invasive phenotype on Escherichia coli HB101. The inv locus allows a uniformly high level of invasion in several tissue culture lines and is homologous to the inv gene of Yersinia pseudotuberculosis. The second locus, ail, shows more host specificity than inv in that it allows invasion to a variable degree of some cell lines (e.g., HEp-2, HEC1B, and CHO cells) but allows no invasion of others (e.g., Madin-Darby canine kidney cells).

A 50-year-old man with diabetes was found to have sepsis with multiple small hepatic abscesses secondary to Yersinia pseudotuberculosis which were detected by computed tomography (CT) scan. Sepsis with Y. pseudotuberculosis is uncommon but usually seen in patients with underlying liver disease. Those patients with liver abscesses invariably have multiple small abscesses. Widespread use of CT scanning is likely to uncover more cases of hepatic microabscesses; in the appropriate clinical setting, Y. pseudotuberculosis should be considered as a possible cause.
