“…This could be due to the low prevalence of the organism, which may compromise statistical analysis. Fecal leukocytes were detected in 40% of S. enterica-positive fecal specimens, results similarly described by Huicho and coworkers (18) . In most cases a supportive treatment with no antibiotics is advised for patients presenting uncomplicated salmonellosis.…”

Introduction: Acute infectious diarrhea is still regarded as a public health problem associated with a wide range of etiologic agents, from which Salmonella enterica is particularly worth mentioning inasmuch as it is a major cause of inflammatory diarrhea in both developed and developing countries. Objective: To assess the distribution of S. enterica among children with acute diarrhea in Belo Horizonte and to characterize bacterium isolates. Material and methods: The study group comprised a total of 157 children from low socioeconomic background. Stool samples were collected for leukocyte analysis and Salmonella bacterial culture. The isolates were serotyped and evaluated as to antimicrobial susceptibility profile, extended-spectrum β-lactamases (ESBL) production, and presence of virulence markers (invA, iroB, and spvC). Results: A total of 5/3.2% children were infected by S. enterica, 3/60% by S. enterica Typhimurium, 1/20% by S. enterica Enteritidis and 1/20% S. enterica subsp. enterica serotype 8.20:z4,z23:-. Fecal leucocytes were detected in two out of five fecal specimens positive for S. enterica. Isolates from three children were resistant to nalidixic acid, nalidixic acid + chloramphenicol, and nalidixic acid + chloramphenicol + ampicillin. ESBL production was not detected. All samples presented invA and iroB genes. spvC marker was observed in isolates from two children infected by S. Typhimurium and S. Enteritidis. Conclusion:The results demonstrate that S. enterica infection is uncommon among children from our region. Furthermore, they indicate the need for periodic monitoring of bacterial antimicrobial susceptibility profile in order to establish suitable antimicrobial therapy when required.

“…Fecal blood and leukocytes are rarely found in coccidial diarrhea, but some studies have reported their presence in a significant number of HIV-seropositive patients. [36][37][38] In the case of mixed infections with S. enteritidis, the role of coccidia in symptoms is difficult to interpret. In the other cases, bloody diarrheas occurred only in patients with low CD4 counts.…”

Abstract. A study of the etiologies of diarrhea in adults in relation to their human immunodeficiency virus (HIV) serostatus and number of CD4ϩ cells was carried out in the Central African Republic. In cases and controls, multiparasitism was observed. Salmonella spp. were identified mainly during acute diarrhea, with 50% of the S. enteritidis isolated during the study being responsible for septicemia and/or urinary tract infection in immunodeficient patients. Enteroaggregative Escherichia coli (EAggEC) were the most frequently identified agent in HIVϩ patients with persistent diarrhea; 42.8% of the patients with EAggEC as sole pathogens had bloody diarrhea, and these strains were negative for the presence of a virulence plasmid. Coccidia were found in those with acute and persistent diarrhea. Blood was observed in 53.3% of infections involving coccidia as the sole pathogen. Microsporidium spp. and Blastocystis hominis were found only in HIVϩ patients with persistent diarrhea. Shigella spp., Campylobacter spp., and Entamoeba histolytica were found in HIVϩ and HIVϪ dysenteric patients; bacteria resembling spirochetes that could not be cultivated were identified only in HIVϩ cases with dysentery. Shiga-like toxin-producing E. coli O157:HϪ was isolated from two cases with hemolytic-uremic syndrome. Fungi were identified as the sole pathogen in 6.4% of the HIVϩ patients with persistent diarrhea. Most of enteropathogenic bacteria identified were resistant to ampicillin and trimethoprim-sulfamethoxazole, remained susceptible to ampicillin plus clavulanic acid, and were susceptible to amikacin, gentamicin, and ciprofloxacin.

“…5 An increase in the number of fecal leukocytes was also found by Huicho et al in 36% of children infected with Salmonella-ShigellaCampylobacter, 16% children infected by Rotavirus or enterotoxigenic E. colli, and 18% children are infected with Cryptosporidial diarrhea. 6 In our study, we found that Salmonella spp and C.difficile respectively of 33.3% and EPEC and Shigella spp respectively of 16.67%, neither Campylobacter nor E.Coli strain other than EPEC were found.…”

Coli Nuraini I Susanti, Reynaldo, Aria Kekalih,Anis Karuniawati, Badriul Hegar enterotoxigenic and rotavirus respectively 16%. 6 DeWitt also determined bacterial infection when fecal leukocyte count > 5/hpf was found.…”
