Sixty-eight proved cases of typhoid and paratyphoid fever were reviewed in a retrospective study covering 5 years (1986-1990). Patients within the age range of 10 to 39 years constituted 82.3 per cent of cases and there was equal incidence in both sexes. The mean duration of illness before presentation was 9.67 days. The major clinical features were fever (97%), abdominal tenderness (-9.4%), headache and abdominal pain (70.58%) each). Intestinal perforation was the commonest complication (27.9%) with a male preponderance (M:F-3:1). Perforation occurred after the first week of illness in 73.7 per cent of cases. Fourteen out of the nineteen patients who perforated were not on therapy at the time of perforation and they constituted 80 per cent of those cases of mortality in which perforation played a role. Surgical management of perforation gave better results than conservative management (mortality rates of 16.7% and 40% respectively). Salmonella was sensitive to Chloramphenicol in all the cases where the organism was grown. There were 10 recorded deaths (14.9%) of whom 60 per cent (i. e. 6 patients) presented after two weeks of illness.

A retrospective epidemiological study was conducted in connection with an outbreak of paratyphoid fever at a Peruvian naval installation in Callao. The study sought to determine the magnitude of the outbreak, the source of infection, the attack rates, the persistence of bacilli excretion, and the clinical picture of the disease. The source of Salmonella paratyphi B infection had been a meal of chicken and rice served to around 400 members of the naval police. Over a period of three weeks, 21 persons were hospitalized and 52 received outpatient treatment at the naval hospital. In addition, through a questionnaire it was revealed that 86 unreported cases of diarrhea related to the outbreak had occurred. The most common clinical manifestations were fever, headache, weakness, anorexia, abdominal pain, and diarrhea. The general attack rate was 39.8%. In a follow-up survey carried out 37 days after exposure, fecal cultures indicated that 8.5% of the persons affected continued to excrete the microorganism. The high rates of attack and transmission of S. paratyphi B in this outbreak point up the considerable pathogenicity and virulence of some strains of the microorganism and their impact on public health. It is suggested that preventive measures be taken at naval and other similar installations, including the education of workers who handle and prepare food, in order to ensure proper hygiene.

A disease with main symptoms of fever, headache, malaise, profuse sweating and diarrhoea occurred as an outbreak in a few villages at suburb of Hengyang City from March to July 1987. It was diagnosed as Type B paratyphoid fever by laboratory examinations. The number of cases occurred in this outbreak was 59 in total. All of them recovered after isolation and proper-treatment.

There is no objective data on the value of individual clinical symptoms or signs in the diagnosis of enteric fever in a febrile patient. The purpose of the study was to assess the value of some clinical and simple laboratory features in the diagnosis of enteric fever. One hundred & six patients with microbiologically confirmed enteric fever and 170 patients with other established febrile illnesses were included in the evaluation. History of stepladder pattern of rise of temperature, loose motions, relative bradycardia and coated tongue proved to be powerful markers of enteric fever with high specificity (100%, 94.71%, 94.71%, 94.12% respectively), positive and negative predictive values. Headache, hepatomegaly and splenomegaly were moderately powerful. ESR and WBC count appeared to have little value in the diagnosis of enteric fever. Pattern of onset and loose motions did not discriminate between typhoid and paratyphoid fever. Most of these patients had illness persisting beyond one week by which viral infections and infectious enterocolitides were largely excluded. Elucidation of power of these markers in distinguishing enteric fever from other febrile illnesses with the help of better designed prospective studies would lessen our dependence on expensive and time consuming laboratory investigations.

The aim of this study was to describe epidemiological and clinical characteristics of imported enteric fever in Czech travellers and to determine the antimicrobial susceptibility of isolated strains. Retrospective descriptive study included adult patients treated with enteric fever at Hospital Na Bulovce during January 2004-December 2012. A case of typhoid or paratyphoid fever was defined as isolation of Salmonella Typhi or Paratyphi from blood or stool. During the study period, there have been diagnosed 19 cases of enteric fever (12 males and 7 females) with age median of 30 years; 14 cases were caused by Salmonella Typhi and 5 cases by S. Paratyphi A. The infection has been acquired in South Asia (16 patients; 84.2 %), in Africa (Egypt, Angola) in two cases (10.5 %), and in Mexico (1; 5.3 %). Symptoms included fever (all patients), diarrhoea (16 cases; 84.2 %), headache (9; 47.4 %), and abdominal pain (7; 36.8 %). Seventeen patients (89.5 %) were treated with fluoroquinolones; however, the treatment failure was observed in seven of them (41.2 %). Decreased ciprofloxacin susceptibility was detected in eight strains (66.7 %), and one strain (8.3 %) was multidrug resistant. Sequence analysis of quinolone resistance-determining regions (QRDR) of the gyrA gene revealed the presence of amino acid substitutions in all tested isolates with decreased ciprofloxacin susceptibility. Typhoid and paratyphoid fevers represent epidemiologically important diseases that may lead to potentially life-threatening complications. Major issue in the management of enteric fever represents the non-susceptibility of Salmonella strains to fluoroquinolones and other antimicrobials.
