Forty-two episodes of culture-proved salmonellosis were found retrospectively among 2,262 patients treated for malignant diseases at St Jude Children's Research Hospital, Memphis. These cases were reviewed in an effort to determine whether Salmonella infections in childhood cancer patients are associated with an increased frequency of septicemia and death, as has been reported for adults with cancer. Septicemia occurred in only 10% of the patients studied, consistent with the frequency established in general populations. There were no deaths attributable to Salmonella infection. Most of the patients (57%) with salmonellosis had gastroenteritis, and the clinical course of this syndrome was no more severe or prolonged than that seen in otherwise normal children. We recommend that management of Salmonella infections in children with cancer follow presently accepted guidelines for normal hosts.

Six children, out of twelve in a neonatal unit suffered from group D salmonellosis. Two patients presented in addition to intestinal manifestations massive extraintestinal symptoms, both with septicemia and meningitis. One patient died on the fourth day from massive disseminated intravascular coagulation and pyocephalus. The other patient had a complete recovery after an antibiotic therapy with chloramphenicol and ampicillin. As the source of infection the mother of case 1 was identified. In her stools salmonella group D were cultured. Cultures of the ward-personals, stool and the food were negative. It should be mentioned that only children fed with artificial food suffered from salmonellosis; whereas children on breastmilk had an unremarkable clinical course and consistantly negative stoolcultures.

The fecal mucus obtained from 110 samples in 50 children with diarrhea was studied. Leukocytes were present in 44 cases and 66 samples were negative. Patients with E. coli 0111 did not show fecal leukocytes in contrast with those with E. coli 0119. Patients with shigellosis showed fecal leukocytes of polymorphonuclear predominance, the same as patients with non-thyphoid salmonellosis. But when septicemia was present, either from salmonella or from other enterobacteria, there was a striking increase in percentage of mononuclears. Several patients with negative stool cultures showed fecal leukocytes of polymorphonuclear predominance which suggested residual inflammatory reaction or presence of bacteriologically unidentified invasive E. coli. The index of diagnostic prediction for this test was 73%. Its routine use is recommended in any child with acute or protracted diarrhea, before the initiation of antimicrobial treatment.

Infections or inflammatory states often cause significant increases in serum phenylalanine and the phenylalanine-tyrosine ratio. More than 95% of samples obtained during inflammatory diseases in man showed phenylalanine-tyrosine ratio increases greater than the maximum normal values. An increase in this ratio also occurred in monkeys with induced Rocky Mountain spotted fever, viral encephalitis, yellow fever, or pneumococcal and Salmonella infections, as well as in rats with pneumococcal and Salmonella infections, as well as in rats with pneumococcal, Salmonella or tularemia infections. A similar ratio increase occurred in rats inoculated with unpurified mediator substances (released by activated leukocytes) that appear to initiate many of the secondary metabolic phenomena associated with infection and/or inflammation. To identify responsible mechanisms, rats were given lethal doses of Streptococcus pneumoniae; serum phenylalanine and phenylalanine-tyrosine ratios increased significantly. Hepatic phenylalanine hydroxylase activities were slightly decreased when compared to noninfected controls. Infected and noninfected rats showed comparable oxidation rates for 14C-phenylalanine given with an oral phenylalanine load, as a pulse-oral dose, or as an intraperitoneal injection. After 8 hr, both infected and control rats had similar amounts of radioactivity in total body protein, but tissue distributions were markedly altered during pneumococcal sepsis. Serum proteins of infected rats contained almost twice as much total radioactivity as that found in controls, while the amount of labeled phenylalanine in skeletal muscle protein was significantly reduced in the infected group. Isolated muscles from infected rats released more phenylalanine and less tyrosine than control muscles. Infection-related increases in serum phenlalanine could not be explained by decreased hydroxylation or oxidation. Rather, the data were consistent with an increased flux of phenylalanine into serum, most likely as the result of increased skeletal muscle catabolism. Elevations in the serum phenylalanine-tyrosine ratio have potential value for estimating the presence of an inflammatory fisease and the catabolic state of a patient.

Six cases of severe salmonella genitourinary infection and a case of salmonella septicemia after prostatectomy are reported. The mechanism whereby the urinary tract is involved in salmonellosis is described, as are the different manifestations of genitourinary salmonellosis. Host factors predisposing to the development of genitourinary salmonella infection include other urologic pathology, malignant neoplasms and states of depressed immunity. Recommendations are made with regard to the diagnosis and management of this sometimes lethal condition.

Although disease caused by Arizona hinshawii is known to resemble the spectrum of clinical syndromes seen with Salmonella infections, little is known of their sensitivity to antimicrobials. We present three cases that are illustrative of Arizona sepsis, localized infection, or both; review the literature; and report sensitivities to 12 antimicrobials for 32 human and animal isolates of Arizona hinshawii from various geographic areas. With the exception of erythromycin and streptomycin, most strains were sensitive to many of the commonly used antibiotics. As with Salmonella infections, ampicillin or chloramphenicol appear to be the initial antimicrobial agents of choice for severe infections with A. hinshawii. Definitive antimicrobial therapy must be individualized on the basis of sensitivity testing and with regard to host factors.

Approximately 200 opossums, trapped during the fall of 1973 in the vicinity of Raleigh, NC, were maintained in the Institute's breeding colony in individual cages until the breeding season. Clinically normal, dead, and moribund opossums were examined for Salmonella. Six serotypes of Salmonella were identified in both clinically normal and diseased opossums. Positive culture results were obtained on 39 of 56 (70%) rectal swab specimens collected in the fall from incoming opossums, and on 30 of 50 (60%) rectal swab specimens collected during midwinter from an additional group of clinically normal opossums, which were maintained in isolation for approximately 3 months before testing. At necropsy, 87 of 108 (81%) diseased opossums were culture positive for Salmonella. Salmonellae in serogroups B and R were isolated from the spleen, liver, kidneys, or heart blood as well as the ileum of 57 diseased opossums. In 23 cases, S typhimurium or S bern was isolated in pure culture from the visceral organs. These findings indicated bacterial septicemia. In contrast, salmonellae in serogroups C1, E1, and F were routinely isolated from the feces of clinically normal and diseased opossums, suggesting a habitat restricted to the intestinal tract and probably the mesenteric lymph nodes. It was concluded that the opossum serves as a reservoir for a number of serotypes of Salmonella and may have an important role in the epizootiology of wildlife salmonellosis.

Salmonellosis includes two groups of diseases: typhoid fever and non-typhic infections. Epidemiological and clinical features are different in each group. Typhoid fever is a major health problem in developing countries. It realizes septicemia and endotoxinic symptoms, and has not to be forgotten when the patient is back from travelling. Non-typhic infections in most cases produce acute feverish diarrhea, conforming with collective food toxi-infection. Non digestive localizations are usually the fact of underlying diseases, and are able to kill the patient.

Salmonella accounts for up to one-third of all primary abdominal aortic infections. During the past ten years, we have treated three patients with this disease and have reviewed an additional 61 instances found in the English literature. The overall survival rate was 46 percent. Fever and back or abdominal pain were present in more than 90 percent of the patients, while a pulsatile mass was present in only 42 percent of those reported. Blood cultures were positive in 73 percent of patients. Computed tomography and angiography were helpful in delineating the presence of aneurysms and defining the extent. Twenty-two patients were treated without undergoing aortic resection; there were no survivors. One patient had an aortic resection without reconstruction and survived. Twenty-eight patients were treated with aortic resection and anatomic reconstruction. Six patients in this group died of graft sepsis and an additional six patients required graft removal for persistent infection. In contrast, 18 of 19 patients treated with extra-anatomic grafting and aneurysm resection survived, with only one death from aortic stump sepsis. No patient has required graft removal for sepsis. These results suggest that aneurysm resection and extra-anatomic bypass is the treatment of choice in patients with Salmonella infections involving the infrarenal aorta.

The septicemia caused by the Arizona group organism is rare and usually observed in adults with underlying diseases. In Korea, Salmonella infection is common, but a report of Arizona infection is unknown. We isolated S. entercia subsp. diarizonae from blood of a 6-month-old infant. The serovar was determined as 28:z10:-, a rare one in America. The isolate was susceptible to ampicillin, chloramphenicol, cotrimoxazole and others. The patient rapidly recovered with ampicillin and gentamicin therapy. Clinical laboratories should consider that the infection exists in Korea and should attempt to isolate and identify Arizona organism in certain patients.
