During a period of 12 months beginning on 18 February 1985, 1246 specimens of faeces from 935 children aged 3 weeks to 12 years with acute diarrhoea of varying severity were examined for the presence of cryptosporidium oocysts. Twenty-six patients required admission to hospital; four of them needed intravenous rehydration. Predominant clinical features were diarrhoea, often watery, and vomiting. Diarrhoea varied in duration between 7-15 days. Cryptosporidium oocysts were found in specimens from 41 patients, an incidence of 4.3%. In four patients an additional enteropathogen was identified (Campylobacter species in two and enteropathogenic Escherichia coli in two - serotypes 0126: K71 (B16) and 018C: K77 (B12]. None of the patients had recently travelled abroad. Of the children 23 were from a farming or rural background. Eight of the farms had recently had significant outbreaks of diarrhoea among calves. There was a marked seasonal variation with 27 of the cases arising between 18 February and 18 June, an incidence during this period of 8%.

The prevalence of viral, bacterial and parasitic pathogens among children of Jeddah, Saudi Arabia, was investigated. During December 1995-October 1996, 576 faecal samples were collected from children (0-5 year(s) old) suffering from acute diarrhoea and attending hospitals and outpatient clinics in Jeddah. One or more enteropathogen(s) were identified in 45.6% of the stool specimens. Mixed infections were detected in 12.2% of the diarrhoeal cases. Rotavirus was detected in 34.6% of the specimens of the hospitalized patients and in 5.9% of the specimens of the outpatients. Fifty-one percent of the rotavirus-positive specimens were long electropherotype, 26% were short electropherotype, and 23% could not be electropherotyped specifically. Among those of the long electropherotype, there were six patterns; and of the short electropherotypes, there were four patterns. Serotyping of these specimens revealed a distribution of 39.6%, 4.2%, 6.3%, and 15.6% for rotavirus serotype 1, 2, 3, and 4 respectively. Mixed serotypes were found in 3.1%, and 31.3% of the specimens were untypeable. Other aetiologic agents recognized included Escherichia coli (13%), of which 3.8% were enteropathogenic E. coli (EPEC) and 1.9% enterohaemorrhagic E. coli. Among the E. coli (EPEC) serotypes, O111:K58:B4, O55:K59:B11, and 0127:K63:B8 were found in 31.8%, 18.2%, and 13.6% of the cases respectively. Serotype 026:K60:B6, 0124:K72:B17, and 0112:K66:B11 each was found in 9.1% of the EPEC cases. 0128:K67:B12 and 0125:K70:B13 each was found in one case only. Other detected pathogens were: Klebsiella pneumoniae (4%), Giardia lamblia (3.1%), Salmonella sp. (3%), Shigella flexneri (2.6%), Entamoeba histolytica (2.2%), Trichuris trichiura, Hymenolepis nana, and Ascaris lumbricoides (0.7% each), and Candida albicans (0.5%). Based on the results of this study, it is concluded that the high prevalence of the various enteropathogens among young children is a significant public health problem.

Mortality from diarrheal diseases is most common in areas with high prevalence of caloric malnutrition. The considerable reduction of mortality from diarrhea following introduction of oral rehydration therapy has revealed the seriousness of persistent diarrhea with malnutrition. Persistent diarrhea is internationally defined as a diarrheal episode lasting 14 days or longer, generally accompanied by growth problems and protein calorie malnutrition. Persistent diarrhea is now considered a nutritional disease, generally occurring in low birth weight or malnourished children and itself a significant cause of protein calorie malnutrition. 10% of episodes of acute diarrhea are believed to evolve into persistent diarrhea, which accounts for 35% of deaths from diarrhea. Around 15% of episodes of persistent diarrhea are fatal. Several risk factors have been identified. Most patients are under one year old. Various studies have shown that protein calorie malnutrition retards repair of the damaged intestinal epithelium and prolongs diarrhea. Recent introduction of milk of animal origin is implicated in 30-40% of episodes of persistent diarrhea. Patients at risk have been shown to react abnormally to skin tests of antigens and to have recent histories of acute diarrhea or previous episodes of persistent diarrhea. Inconclusive studies implicate antimotilic drugs such as paregoric elixir and indiscriminate use of antibiotics as risk factors, but increased risk has been proven only with some antiparasitics. Patients with persistent diarrhea are deficient in vitamins A, B12, and folic acid, and in zinc and iron. Children under 6 months of age with persistent diarrhea should be hospitalized. Adequate feeding is the most important aspect of treatment. The objectives of nutritional treatment include temporary reduction of milk of animal origin, assurance of sufficient protein and calorie consumption, avoidance of foods aggravating the diarrhea, and correction of existing malnutrition.

Probiotic ingestion is recommended as a preventive approach to maintain the balance of the intestinal microbiota and to enhance the human well-being. During the whole life of each individual, the gut microbiota composition could be altered by lifestyle, diet, antibiotic therapies and other stress conditions, which may lead to acute and chronic disorders. Hence, probiotics can be administered for the prevention or treatment of some disorders, including lactose malabsorption, acute diarrhoea, irritable bowel syndrome, necrotizing enterocolitis and mild forms of inflammatory bowel disease. The probiotic-mediated effect is an important issue that needs to be addressed in relation to strain-specific probiotic properties. In this work, the probiotic properties of new Lactobacillus and Bifidobacterium strains were screened, and their effects in vitro were evaluated. They were screened for probiotic properties by determining their tolerance to low pH and to bile salts, antibiotic sensitivity, antimicrobial activity and vitamin B8, B9 and B12 production, and by considering their ability to increase the antioxidant potential and to modulate the inflammatory status of systemic-miming cell lines in vitro. Three out of the examined strains presenting the most performant probiotic properties, as Lactobacillus plantarum PBS067, Lactobacillus rhamnosus PBS070 and Bifidobacterium animalis subsp. lactis PBSO75, were evaluated for their effects also on human intestinal HT-29 cell line. The obtained results support the possibility to move to another level of study, that is, the oral administration of these probiotical strains to patients with acute and chronic gut disorders, by in vivo experiments.
