48 patients admitted to a rural Bangladesh hospital with dehydration secondary to diarrhea were examined for infection caused by (R.L.A.) reovirus-like agent or (E.T.E.C.) enterotoxigenic Escherichia coli. The diagnosis of R.L.A. infection was established by electron microscopy of stool filtrates and by a 4-fold or greater rise in serum complement-fixing antibodies to the Nebraska calf diarrhea virus. Evidence of infection by heat-labile-toxin producing E.T.E.C. was sought by stool culture and serological testing using the adrenal cell tissue-culture system. Infection by heat-stable-toxin producing E.T.E.C. was sought by stool culture using the infant mouse test. 12 patients, all less than 2 years old, had evidence of R.L.A. infection, accounting for illness in 5% of the 22 patients under 2. None of these 22 had evidence of E.E.T.E.C. infection. R.L.A. diarrhea lasted 5-6 days, often led to serious dehydration, and was associated with vomiting and fever. 11 cases of E.T.E.C. diarrhea were detected, accounting for 56% of the cases of diarrhea in the 18 patients who were more than 10 years old. Diarrhea caused by E.T.E.C. was sudden in onset, shorter in duration, and caused pronounced dehydration. In a community survey, E.T.E.C. was isolated with equal frequency in the stools of control and case family members. Data suggest that E.T.E.C. is a common cause of adult diarrhea in Bangladesh while R.L.A. is a common cause of diarrhea in children.

A fecal filtrate of human origin containing the Norwalk agent of epidemic viral gastroenteritis was administered by stomach tube to chimpanzees in an attempt to induce diarrheal disease. Significant postchallenge serum antibody rises against Norwalk viral antigens were demonstrated in all animals using the techniques of immune electron microscopy and radioimmunoassay. In addition, viral antigens were detected in feces from five of nine animals using radioimmunoassay. Clinical illness characterized by diarrhea and/or vomiting did not occur. Infection was transmitted subsequently by feeding four additional chimpanzees a fecal filtrate prepared from one of the previously infected animals. Development of an antibody response in four animals and detection of viral antigen in two animals that received this passage filtrate indicated that viral replication had occurred in the absence of clinical illness. The availability of the chimpanzee as an experimental animal host susceptible to infection with the Norwalk agent should facilitate the study of epidemic viral gastroenteritis.

Since in the past, Aeromonas hydrophila had been isolated from all cases of human infection described. A. punctata and the anaerogenic sub-species were considered as apathogenic. From the case described, a close association between acute diarrhea with vomiting and the identification of A. punctata subsp. caviae becomes evident so that a conditional pathogenicity of this sub-species must be assumed. The question is discussed whether a preceding disturbance of the intestinal habitat in the presence of a particular susceptibility of the gastrointestinal tract promoted gastro-enteritis. Infection may have been brought about by the ingestion of surface water contaminated by sewage. Attention is again drawn to the fact that in the case of enteritis occuring during the open-air bathing season, faeces samples should also be examined for their Aeromonas content which may be performed by a simple indophenol or so-called cytochrome oxidase reaction of the aerobic flora in feces by rubbing off colonies into a corresponding test strip.

The electronmicroscopic examination of stool samples from 18 infants and young children with gastroenteritis, hospitalized at the Clinic of Infectious Diseases in Prague, was carried out. In ten children rotavirus was found in the faeces and the bacteriological findings were negative. Rotavirus particles were aggregated by convalescent child sera and by normal human gamma globulin. The clinical picture was characterized by the sudden onset of vomiting and fever, in one case with febrile convulsions. Diarrhoea was watery and yellow-green, and usually persisted for four to five days. The condition of the children improved rapidly after rehydration and a special diet. Older siblings, and in one family also adult members, were frequently affected.

The cause of diarrhea in a Rochester, Minnesota, pediatric population was studied by examining specimens for the presence of enterotoxigenic strains of Escherichia coli and reovirus-like agents, in addition to parasites and other bacteria and viruses. Reovirus-like agents were detected by electron microscopy in the feces of 11 of 31 patients, but none was found from specimens collected during convalescence or from 16 asymptomatic matched controls (P less than 0.01). Infection due to reovirus-like agents occurred significantly more often during the winter months in patients 6 to 18 months of age. Vomiting and diarrhea most often occurred simultaneously. All patients recovered without significant complications or sequelae, although one child was hospitalized for 3 days. Mean duration of illness was 9 days. No enterotoxigenic strains of E. coli were detected from symptomatic or control groups. Our results show that of the 16 organisms detected in stool specimens (11 reovirus-like agents, 3 salmonellae, and single isolates of adenovirus and enterovirus), the reovirus-like agent was the most frequent (69%) and was the probable etiologic agent in 35% of the cases of diarrhea in Rochester children.

A comparative trial of pivmecillinam and ampicillin was performed on 100 women with bacteriuria of pregnancy. They received either 400 mg pivmecillinam four times daily or 500 mg ampicillin four times daily for seven days. Cure rates at two weeks were 88% in the pivmecillinam group and 85% in the ampicillin group. At six weeks the respective rates were 76% and 64%. Failure of therapy was not associated with the appearance of bacterial resistance in either treatment group. Side-effects, particularly vomiting and premature cessation of therapy, were significantly more frequent in the pivmecillinam group. No significant effects on liver function were found. In subsequent patients treated in a non-comparative manner with 200 mg pivmecillinam three times daily, the incidence of side effects was markedly reduced with no loss of efficacy.

In 37 children with Campylobacter enteritis seen over a 6-month period, ages ranged from 2 weeks to 15 years. The sex ratio (male:female) was three:two. Fever, diarrhea, and bloody stools occurred in about 90% of patients. Blood appeared in the stools characteristically 2 to 4 days after onset of symptoms. Over 90% of older children developed abdominal pain. Vomiting was mild and occurred in 30% of patients. Dehydration was not a feature. Infection occurred in all social classes and was not associated with parental occupation, travel, or animal contact. The illness often presented characteristically and a rapid laboratory diagnosis could be made in patients presenting acutely by direct phase-contrast microscopy of stools. The organism persisted in the stools for up to seven weeks in untreated patients, but could no longer be cultured after 48 hours of therapy with erythromycin, to which all strains were highly sensitive. Significant serologic responses were elicited using a serum bactericidal assay. The Skirrow-type selective medium used by us could be improved by increasing the concentration of polymyxin B sulfate to 5 microgram/ml.

Campylobacter jejuni/coli has recently become recognized as a common bacterial cause of diarrhea. Infection can occur at any age. The usual incubation period of campylobacter enteritis is 2 to 5 days. Fever, diarrhea and abdominal pain are the most common clinical features. The stools frequently contain mucus and, a few days after the onset of symptoms, frank blood. Significant vomiting and dehydration are uncommon. A rapid presumptive laboratory diagnosis may be made during the acute phase of the illness by direct phase-contrast microscopy of stools. Isolation of the organism from stools requires culture in a selective medium containing antibiotics and incubation under reduced oxygen tension at 42 degrees C. The organism persists in the stools of untreated patients for up to 7 weeks following the onset of symptoms. Erythromycin may produce a rapid clinical and bacteriologic cure, and should be used to treat moderately to severely ill patients as well as patients with compromised host defences. The emergence of erythromycin-resistant strains requires close monitoring. The epidemiologic aspects of campylobacter enteritis will be fully understood only when methods become available for differentiating strains of C. jejuni/coli. The historical background and current knowledge of campylobacter enteritis are reviewed in this paper.

Infection of the peritoneal cavity with cestode larvae, presumptively diagnosed as tetrathyridia of the genus Mesocestoides, was found by exploratory celiotomy in a dog with clinical signs consisting of episodic anorexia, vomiting, and depression. Lymphopenia and hypoalbuminemia were associated clinicopathologic abnormalities. Dystrophic calcification and midline duodenal displacement were found on abdominal radiographs. Therapy with mebendazole was instituted after recurrence of the initial episodic clinical signs postoperatively. Daily use of mebendazole for intermittent periods of up to 3 months led to remission of gastrointestinal signs for 30 months. However, 17 months after the initial diagnosis, infection of the vaginal tunic of the testicle with similar cestode larvae necessitated castration and removal of the vaginal tunic to the inguinal ring. Mebendazole therapy was reinstituted and continued for 31/2 months postoperatively. The dog was free of clinical signs of infection during and for the 16 months since this period of treatment.

During the period from September 8 to October 2, 1970, 44 of the 120 children and 78 of 141 adults questioned at the Children's Asthma Research Institute and Hospital experienced gastroenteritis characterized by nausea, vomiting, and fever and/or chills. Diarrhea was rare in children (4.5%) and common in adults (74%). The median duration of illness for children, 18 hours, was significantly shorter than the 48 hours for adults. All viral and bacterial cultures of 30 stool specimens were negative for viruses and bacterial pathogens. A retrospective survey of 28 ill employees revealed a secondary attach rate of 46% of 76 family contacts. A bacteria-free filtrate prepared from stool swab specimens of 2 ill adults by a team at the National Institute of Allergy and Infectious Diseases was administered orally to 3 adult volunteers. One of the 3 vomited and had 4 watery diarrheal stools on the third post-inoculation day. Diarrheal stool filtrates from this person were then given orally to 8 others; 1 became ill. Although the epidemiologic features point to the respiratory route of infection, the probably successful serial transmission of disease via bacteria-free stool filtrates through 2 generations of volunteers also suggests that the "Denver agent" is a virus-sized particle that replicates in the gastrointestinal tract.
