[Serological recognition of agglutinins against O and H antigens of various Salmonellae in "normal" adult subjects].

The distribution of Salmonella agglutinins among 390 normal sera from people living in the district of Pisa is described, and the relation of these findings with the Salmonella serotypes occurring in the same area is discussed. Clusters of agglutinins for several O and H antigens were found at or above a titre of 1:20, in many samples. In order to explain the significance of such antibodies and their origin an identical survey was carried out on some sera from patients with chronic liver disease, using the same antigens suspensions. The results from healthy persons compared with the increased antibody titres detected in liver patients support the hypothesis that the anti-Salmonella agglutinins may be originate by various antigenic stimuli which may be specific or most frequently non-specific, since it is well established the cross-reactivity between both the somatic and flagellar antigens of Salmonella and those of other organisms.

[A new serotype of Salmonella: "Salmonella pisa (16:i:l,w)" (author's transl)].

A new Salmonella serotype with the antigenic formula 16:i:l,w and named S. pisa is described. The strain was recovered from the feces of a healthy person who had suffered enteritis during a previous sojourn in Ghana. The W.H.O. Salmonella Centre of Paris confirmed the antigenic structure and agreed with this designation.

[Isolation of halophilic vibrios as possible agents of food poisoning (author's transl)].

Seventy-six halophilic vibrio strains were isolated from different marine sources such as coastal waters, fishes and mussels. Twenty strains were identified as Vibrio parahaemolyticus, 44 as Vibrio alginolyticus and 12 other strains could not be classified because of their atypical biochemical activities. Further investigations are necessary in order to assess if the present strains of V. parahaemolyticus can have a role in food poisoning outbreaks or human sporadic enteritis in our geographic area.

[Polyresistant "Salmonella bredeney" in a general surgical ward (author's transl)].

A series of cases of postoperative gastroenteritis by Salmonella bredeney in a general surgical ward has been described. The particular serotype of Salmonella in question, the widerange of drug-resistance of the strains, the epidemiological stages of the outbreak and the kind of the ward interested have been considered of uncommon occurrence.

[Epidemiological remarks on the "S. Arizonae" strains isolated from various animals in tuscany during 1969-1978 (author's transl)].

After a review of the taxonomic history of the genus Arizona culminated in the insertion of these bacteria in the Kauffmann-White schema, the most significant references concerning their pathogenicity and occurrence are related. In this paper, the outbreaks and sporadic cases by S. arizonae which occurred in Tuscan area during 1969-1978 are reported; between several animal species, turkeys were found frequently infect and the same serotype (S. arizonae 18:Z4,Z32:-) was identified. The epidemiological connections with the infection of turkeys and of other animals, humans inclusive, are discussed.

[Presence of salmonellae, E. coli and their homologous phages in the seawater].

Comparative experiments were carried out on samples of sea water at different degrees of natural pollution. The aim of such experiments was the quantitative estimation of coliforms and salmonellae and their respective phages. The results obtained show that it is thus possible to get better informations regarding the nature and degree of water pollution, than these obtained by the E. coli count alone.

[The evaluation of day hospital activities: an analysis of intervention protocols and a comparison between the indicators of the activities of the day hospital and of the regular admission].

Day hospital (DH) activity may avoid in-staying of patients resulting in an increase of efficiency and in a more satisfying diagnostical-therapeutical process for the patient. All the same, it is quite difficult to identify parametres and indicators to be used in the evaluation and quantification of DH, so that both scientific literature reporting experiences and law are lacking. One of the reasons is probably due to the lack of nosological characterization of patients and protocols of DH activity, so that the definition relies only on organizational and technical parameters. Characterization of protocols of intervention is the basic approach to the present DH investigation. Parameters such as: multiplicity of services, weekly planning of the activity and surveillance needed by the patient are considered the fundamental criteria to identify and quantify DH in the present research carried out at the University Regional Hospital of Pisa. The aim of this article is, on one side, to give a methodology of investigation based, as far as possible, on "explicit" indicators and parameters, so that the experience may be exported into other contexts and on the other, to give an example of resource analysis and efficiency evaluation which were internally used for "audit" review.
