We reported a case of salmonellosis treated with ofloxacin (OFLX) which showed excellent clinical and bacteriological effect in a 22 year-old Japanese male with Salmonellosis paratyphi A. He had stayed in India from Sept. 6, 1990 to Oct. 13, 1990. On Oct. 25, 1990, he complained of a high fever and headache. On Oct. 29, he was admitted to our hospital and was diagnosed as Salmonellosis paratyphi A by the blood culture. He was treated with 2.0 g/day of chloramphenicol (CP) for 7 days, but the clinical efficacy was not sufficient. Therefore, we added 900 mg/day of OFLX for 10 days. He was treated successfully with them, the temperature became on the 2nd day. No side effect and no changes of laboratory data were observed and no recurrence was observed clinically and bacteriologically for three months after his discharge.

Recurrent episodes of salmonellosis, including recurrent life-threatening bacteremias, have been well-described in patients with AIDS. Because of the need to avoid sensitization to trimethoprim-sulfamethoxazole (TMP-SFX) in AIDS patients and the high frequency of ampicillin resistance of Salmonella isolates, alternative therapies must be sought. We report the treatment of nine AIDS patients, who had recurrent salmonellosis, with norfloxacin, a new oral fluoroquinolone which has excellent in vivo activity against Salmonella sp. Each patient had two to three prior distinct clinical episodes of salmonellosis which had failed to be eradicated with standard courses of ampicillin, TMP-SFX, ceftriaxone or cefotaxime. Microbiologic relapse had occurred in each patient within 2-4 weeks. Each of the enteric pathogens was susceptible in vitro to norfloxacin. Patients were treated with norfloxacin 400 mg bid orally for 30 days. Stool cultures were negative at 1 week in all patients. Nausea and headache were the only adverse reactions to norfloxacin noted. One patient had a clinical and microbiologic relapse of Salmonella 1 week after norfloxacin was stopped but responded to retreatment with norfloxacin. Norfloxacin appears effective in the treatment of enteric infections in AIDS patients and may be more useful than standard agents in eradicating the organism and preventing clinical and microbiologic relapse. Oral administration and twice daily dosing are significant advantages.

The clinical and immunological responses to typhoid vaccination with parenteral (TAB) and oral (Ty21a) vaccines in two groups of 30 adult male subjects were studied. Parameters monitored included specific anti-Salmonella typhi cell-mediated immunity and total and specific antilipopolysaccharide fecal immunoglobulin A (IgA) titers in Ty21a-vaccinated subjects. Peripheral blood lymphocytes antibacterial activity was significantly increased only in Ty21a-vaccinated subjects. Serum arming activity and results of human F(ab')2 anti-IgG and -IgA inhibition tests suggest antibody-dependent cellular cytotoxicity mediated by IgA in those vaccinated with Ty21a. Interestingly enough, the cells of TAB-vaccinated subjects were able to mediate IgG-dependent cellular cytotoxicity, as was observable from the results of blocking experiments. Moreover, total and specific antilipopolysaccharide fecal IgA levels were observed to be significantly increased with Ty21a, up to 8 months post-vaccination schedule. An early-onset, transitory increase in serum IgM rheumatoid factor was also found, exclusively in subjects treated with TAB, and was no longer detectable on day 240. Ty21a was well tolerated and free of side effects, whereas 65% of subjects administered TAB reported fever, headache, malaise, and local tenderness at the injection site. Our data show that the two typhoid vaccines induce different cell-mediated specific immune responses. The role of these responses in protection against Salmonella infection, however, requires further investigation.

Non-typhoid salmonellosis remains a common infective illness. We studied 77 consecutively admitted children aged 1 month to 15 years in order to determine frequency of antecedents, the strain of the isolated organisms, clinical findings, frequency of complications and the adequacy of management. The presentation and severity of the illness were compared between younger than two and older children. Salmonella typhimurium was isolated in 65% of the cases. Two thirds of the tested strains were multiresistant to antibiotics. Non-typhoid salmonellosis usually occurred in the form of acute gastroenteritis: in only 4% of the cases it presented as pyrexia of unknown origin without gastrointestinal symptoms. 30% of the cases had been exposed to one or more antimicrobial agents within four weeks before the date of their stool culture. Only 30% had been breast fed. Previously diagnosed cow's milk protein intolerance resulted to be present in 14% of the less than two years old children (p < 0.02). Abdominal pain and headache were found more frequently in older children (p < 0.02). Protein C reactive values were significantly higher in this age group (p < 0.05). 25% of the children were mildly or moderately dehydrated. Hypernatremia was uncommon. 31% of the cases were treated with antibiotics: the antimicrobial treated children presented diarrhoea for longer period (p < 0.05) and they remained admitted for longer time (p < 0.00).(ABSTRACT TRUNCATED AT 250 WORDS)

Salmonella typhimurium phage type (PT) or definitive type (DT) 104 is a virulent pathogen for humans and animals, particularly cattle. It has been isolated increasingly from humans and animals in the United Kingdom and several other European countries and, more recently, in the United States and Canada. Humans may acquire the infection from foods of animal origin contaminated with the infective organism. Farm families are particularly at risk of acquiring the infection by contact with infected animals or by drinking unpasteurized milk. The symptoms in cattle are watery to bloody diarrhea, a drop in milk production, pyrexia, anorexia, dehydration and depression. Infection may result in septicemic salmonellosis and, upon necropsy, a fibrinonecrotic enterocolitis may be observed. The infection occurs more commonly in the calving season than at other times. Feedlot cattle and pigs may also be affected. Prolonged carriage and shedding of the pathogen may occur. Symptoms in humans consist of diarrhea, fever, headache, nausea, abdominal pain, vomiting, and, less frequently, blood in the stool. Salmonella typhimurium DT104 strains are commonly resistant to ampicillin, chloramphenicol, streptomycin, sulfonamides, and tetracycline.

Salmonellosis is a worldwide health problem; Salmonella infections are the second leading cause of bacterial foodborne illness in the United States. Approximately 95% of cases of human salmonellosis are associated with the consumption of contaminated products such as meat, poultry, eggs, milk, seafood, and fresh produce. Salmonella can cause a number of different disease syndromes including gastroenteritis, bacteremia, and typhoid fever, with the most common being gastroenteritis, which is often characterized by abdominal pain, nausea, vomiting, diarrhea, and headache. Typically the disease is self-limiting; however, with more severe manifestations such as bacteremia, antimicrobial therapy is often administered to treat the infection. Currently, there are over 2,500 identified serotypes of Salmonella. A smaller number of these serotypes are significantly associated with animal and human disease including Typhimurium, Enteritidis, Newport, Heidelberg, and Montevideo. Increasingly, isolates from these serotypes are being detected that demonstrate resistance to multiple antimicrobial agents, including third-generation cephalosporins, which are recommended for the treatment of severe infections. Many of the genes that encode resistance are located on transmissible elements such as plasmids that allow for potential transfer of resistance among strains. Plasmids are also known to harbor virulence factors that contribute to Salmonella pathogenicity. Several serotypes of medical importance, including Typhimurium, Enteritidis, Newport, Dublin, and Choleraesuis, are known to harbor virulence plasmids containing genes that code for fimbriae, serum resistance, and other factors. Additionally, many Salmonella contain pathogenicity islands scattered throughout their genomes that encode factors essential for bacterial adhesion, invasion, and infection. Salmonella have evolved several virulence and antimicrobial resistance mechanisms that allow for continued challenges to our public health infrastructure.

Salmonellosis is a bacterial disease that causes acute gastroenteritis, with sudden onset of headache, abdominal pain, diarrhoea, nausea and sometimes vomiting. Infection is often associated with the consumption of foods prepared using raw eggs. During July to August 2008 an outbreak at an aged care facility (ACF) in New South Wales was confirmed as Salmonella Typhimurium phage type 44 (Stm 44) in eight of 45 residents. Two additional probable cases also occurred. Cases were located in each unit of the ACF and for 5 cases, onset of diarrhoea was between 45 to 64 hours (median of 46 hours) after consumption of a dessert containing raw eggs. Onset for 5 further cases occurred up to 9 days after this meal. Eggs were supplied to the ACF from a local farm. Stm 44 was detected on an egg in an unopened box at the ACF from this supplier. The raw-egg dessert was epidemiologically implicated as the likely source of the Salmonella and delayed onset cases may have resulted from ingestion of a smaller dose of Salmonella, or ongoing transmission through cross-contamination of kitchen machinery or surfaces. This outbreak demonstrates that inadequate cooking of eggs continues to pose a risk for Salmonella infection in settings with vulnerable populations. The findings of the investigation provide support for the importance of food safety regulations and demand further advocacy for measures to reduce the risks associated with the distribution, storage and preparation of shell eggs.

Although salmonellosis is a common endemo-epidemic disease in Benin, there is a paucity of data about it. The purpose of this cross-sectional study was to determine the incidence of major salmonellosis requiring hospitalizaton and to describe its epidemiological, clinical, and serologic features as well as treatment and outcome. Consecutive cases observed at the Medical Department of Parakou University Hospital in Benin between January 1, 2005 and December 31 2007 were included. Salmonellosis was defined on the basis of clinical and serological criteria. Among the 2,520 patients hospitalized during the study period, salmonellosis was diagnosed in 135 (5.4% [95% CI 4.5%-6.3%]). Highest incidences were observed in January, July, October and November. The main symptoms were headache, fever, fatigue and abdominal pain. The Salmonella typhi serotype was identified in 94.8% of patients. Two patients presented co-infection, i.e., Salmonella typhi with paratyphi A in one case and Salmonella typhi with paratyphi B in the other. Fluoroquinolones were used for treatment in 79.3% of patients. Outcome was favorable in 62.2%. The main complications were,typhoid digestive perforation in 11.1%, and gastrointestinal bleeding in 8.1%. The mortality rate was 4.4% (n=6). These data are consistent with previous reports in the literature and confirm the frequency and severity of salmonellosis in Benin.

Q fever which is caused by Coxiella burnetii, is a worldwide zoonosis. Many species of wild and domestic mammals, birds, and arthropods, are reservoirs of C.burnetii in nature, however farm animals are the most frequent sources of human infection. The most frequent way of transmission is by inhalation of contaminated aerosols. The clinical presentation of Q fever is polymorphic and nonspecific. Q fever may present as acute or chronic disease. In acute cases, the most common clinical syndromes are selflimited febrile illness, granulomatous hepatitis, and pneumonia, but it can also be asymptomatic. Fever with hepatitis associated with Q fever has rarely been described in the literature. Herein we report two cases of C.burnetii hepatitis presented with jaundice. In May 2011, two male cases, who inhabited in Malkara village of Tekirdag province (located at Trace region of Turkey), were admitted to the hospital with the complaints of persistent high grade fever, chills and sweats, icterus, disseminated myalgia and headache. Physical examination revealed fever, icterus and the patient appeared to be mildly ill but had no localizing signs of infection. Radiological findings of the patients were in normal limits. Laboratory findings revealed leukocytosis, increased hepatic and cholestatic enzyme levels, and moderate hyperbilirubinemia- mainly direct bilirubin, whereas serum C-reactive protein and erythrocyte sedimentation rate were found normal. Blood and urine cultures of the patients yielded no bacterial growth. Serological markers for acute viral hepatitis, citomegalovirus and Epstein-Barr virus infections, brucellosis, salmonellosis, toxoplasmosis and leptospirosis were found negative. Acute Q fever diagnosis of the cases were based on the positive results obtained by C.burnetii Phase II IgM and IgG ELISA (Vircell SL, Spain) test, and the serological diagnosis were confirmed by Phase I and II immunofluorescence (Vircell SL, Spain) method. Both cases were treated with doxycycline for 14 days and became afebrile within four days. These cases were presented to emphasize that C.burnetii infection should be considered in the differential diagnosis of patients with fever and elevated serum transaminase levels, irrespective of the presence of abdominal pain and exposure to potentially infected animals.
