The clinical records of 185 cases of Salmonellosis have been reviewed retrospectively, in order to study a relation between the evolution and the treatment given, so as to be able to determine the therapeutic criteria. 139 cases showed as gastroenteritis, 48 of which received antibiotic treatment and 91 did not. Statistic differences were observed in favour of the non treated cases where, the average time of hospitalization, the negative copro-cultive and the onset of complications were more favourable. All the cases with Tipho-Paratific fever were treated with antibiotics without finding any significant differences in the clinical evolution not withstanding the antibiotic used. The data here obtained is compared with that previously reported. According to the results a treatment planning is suggested.

Methods for estimating the economic impact of disease agents were developed and utilized to assess the relative economic importance of rotavirus and other disease agents in calves. Based on incidence data from 2 sources, Escherichia coli was responsible for the most devastating economic losses (50.9% and 74.6%). Coronaviral (17.5% and 29.7% loss) and rotaviral (3.2% and 9.1% loss) infections ranked 2nd and 3rd, respectively. In one study, cryptosporidial infections (6.5% loss) were estimated to be similar in economic impact to rotaviral infection. Salmonellosis, mycotic gastroenteritis, infectious bovine rhinotracheitis, and bovine viral diarrhea infections accounted for minor losses. The estimated average annual loss of calves for the 7-year period, 1970 through 1976, was $95,500,000/year. Based on data from 2 studies, the estimated average annual loss from E coli was $48.6 and 71.2 million; from coronaviral infection, $16.7 and 28.4 million; from rotaviral infection, $3.1 and $8.7 million; and from cryptosporidial infection, from 1 study, $6.2 million. Estimates of economic impact of disease agents on calves, and likely in other species, indicate that rotaviral infections have a relatively minor role with respect to E coli and coronaviral infections.

During a 21-month period from April 1974 to February 1976, 948 children with gastroenteritis were studied. Aetiologic agents were identified in 43% of these patients. Isolates were identified as follows: V. cholera El Tor, 273 (67%); Salmonella enteritidis, 64 (16%); enteropathogenic E. coli, 28 (7%); Shigella, 28 (7%); Vibrio (NAG), 9 (2%): and V. parahaemolyticus, 7,2%). Gastroenteritis with dehydration is a serious continuing pediatric problem in Jakarta, constituting 30% of admissions to Sumber Waras hospital. The incidence of both cholera and salmonellosis increased during the past 2 years, as judged by the distribution of enteric bacteria isolated from the rectal swabs of gastroenteritis patients in Sumber Waras hospital.

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.

The epidemiology of Salmonella infections in Sassari in the last four years was reported. The remarkable increase of gastroenteritis caused by uncommon Salmonella and by S. wien in 1975 and 1976 was point out: about all cases were related with 3 epidemic episodes in hospitalized patients that were notified as paratyphoid cases in 91% and as infancy's gastroenteritis in 9%. The 201 strains of Salmonella isolated from June 1975 to May 1976 belong for 91% to group B (for 80,5% to S. wien), for 2% to group C1, for 1,5% to group C2, for 5% to group D1 and for 0,5% to group E4. The hypothesis on introduction of S. wien in Sardinia were examined; the rules for limitation of Salmonella diffusion and for prevention of the endemicity of new imported strains, were examined.

An analysis of data on Salmonella infection treated at the Children's Hospital "La Fe", in Valencia, from 1974--75 is presentd. A patient population of 211 selected cases were divided into two groups: Gastroenteritis (GEC), 155 cases, and typhoid-paratyphoid fever (T-P F), 56 cases. Hospitalization was required in 79% of the cases. The following parameter were studied: Locality and district of origin with respect to residence, conditions of hygiene, size of family: age, sex, seasonal incidence, previous time of illness, presenting symptoms and physical sings and complementary studies. The following conclusions were obtained: Salmonella infection are and endemic problem in Valencia. Their incidence is maximal during the months of June to October. Epidemiological environment was positive in 15% of the cases. Higher morbidity in children less than two years of age. Most frequent presenting symptoms: Diarrhea, fever and vomiting as often in GEC as in T-P F. In 38.7% of GEC cases, the diarrhea was bloody; 21.9% of GEC cases began with fever. Salmonella paratyphi B was the agent most frequently responsible. Data concerning sex, family size, conditions of hygiene and white blood cells offer little discriminatory information. Results obtained are concordant with those described in the literature.

Between December 21, 1969, and April 14, 1970, 44 symptomatic cases of Salmonella typhimurium gastroenteritis occurred among the approximately 2500 Sioux Indians of the Lake Traverse Reservation in South Dakota. Twenty-five cases were confirmed by positive stool culture. All 19 cases not confirmed by culture had diarrhea and were epidemiologically associated with the culture-proven cases. Fourteen of these were discovered during the course of the investigation and had not been cultured previously. Twelve cases were hospital-acquired and 32 community acquired. Both the nosocomial and community-acquired infections occurred randomly during the 17-week span of the epidemic. Despite extensive investigation, no common exposure was discovered. The hospital-acquired infections all occurred in patients who shared a room or nursing personnel with patients who had active disease, or were born of a woman with active disease at the time of parturition. Twenty-nine of the 32 community acquired cases were linked to each other by person-to-person contact. This epidemic is the first documented outbreak of non-institutional salmonellosis propagated by person-to-person transmission.

During the period January 1969 through October 1973, rectal swabs from 13,947 diarrhea patients of all ages at infectious disease hospital and children hospital in Saigon were examined. From these specimens 610 strains of Salmonella of all group were isolated. A total of 46 serologic types were encounted. The most commonly encounted were S. paratyphi B, S. java and S. typhimurium (group B). Most of Salmonella isolated were obtained from adult gastroenteritis. We have also studied the possible relation between human and animal salmonellosis. The rodents trapped from different aera in Saigon, fish and clams collected from different markets were examined by bacteriological surveys. From these specimens, 42 strains of Salmonella were isolated for a 2,2 percent isolation rate. Our study showed that Salmonella types which were isolated frequently from animal were encounted in man.

A study on 25 hospitalized children with salmonellosis in the two forms of typhoid fever and gastroenteritis is reported. It confirms the higher incidence of gastroenteritic forms under the age of 3 years, and of typhoid fever in older children. We verify the limited value of the white cell count and the enlargement of the spleen. An appraisal of the serologic tests is made. The direct relationship between group D salmonella and typhoid fever form is pointed out. Finally we analyze the action of ampicillin, chloramphenicol and trimethoprim-sulphamethoxazole, due to the current appearance of resistances to antibiotics.

There are an estimated 2 million cases of salmonellosis in the United States every year. Unlike the incidence of many infectious diseases, the incidence of salmonellosis in the United States and other developed countries has been rising steadily over the past 30 years, and the disease now accounts for 10 to 15% of all cases of acute gastroenteritis in the United States. The infecting organism is ingested and must traverse the intestinal epithelium to reach its preferred site for multiplication, the reticuloendothelial system. Despite several recent studies, the genetic basis of the invasion process is poorly understood. An emerging theme from these studies is that wild-type Salmonella organisms probably have several chromosomal loci that are required for the most efficient level of invasion. In this study, we have identified and characterized 13 TnphoA insertion mutants of Salmonella enteritidis CDC5 that exhibit altered invasion phenotypes. The mutants were identified by screening a bank of TnphoA insertions in S. enteritidis CDC5str for their invasion phenotype in three tissue culture cell lines (HEp-2, CHO, and MDCK). These 13 mutants were separated into six classes based on their invasive phenotypes in the tissue culture cell lines. Several mutants were defective for entry of some cell lines but not for others, while two mutants (SM6 and SM7) were defective for entry into all three tissue culture cell lines. This suggests that Salmonella spp. may express more than one invasion pathway. Southern analysis and chromosomal mapping indicated that as many as nine chromosomal loci may contribute to the invasion phenotype. It is becoming clear that the invasive phenotype of Salmonella spp. is multifactorial and more complex than that of some other invasive members of the family Enterobacteriaceae.
