Abstract
The electrophoretic and immunochemical methods as well as gelfiltration through Sephadex G-200 showed that there are no immunoglobulins in blood serum of fetuses and new-born calves. Specific proteins in a zone of gamma-globulins electrophoretic mobility which correspond to Ig M and Ig A are found in the serum of calves 3 hrs after their feeding on colostrum. The content of these proteins reaches the maximum on the third day of life but at the age of three months it lowers up to minimum. On the third month after birth in the blood serum of calves there appears a new protein in a zone of gamma2-globulins mobility which correspond to Im G-main immunoglobulin of adult animals. An assumption is advanced that the protective functions of calves of the early age are found chiefly with immunoglobulins Ig M and Ig A.

Abstract
Enzyme immunoassays (ELISA) have been developed for the detection of BK virus IgG- and IgM-antibodies. Specific IgG is detected by an antigen-coated solid phase test; IgM by an antibody capture method. These methods have been used to study the age-distribution of BK virus antibodies in Tromsø county in Northern Norway. The serum panels tested were: 60 sera from paediatric patients aged 0-1 year; 220 sera from healthy persons aged 1-82 years; 74 sera from healthy blood donors; 107 sera from healthy pregnant women. The age-distribution of BKV-IgG antibodies showed that primary infections took place predominantly between the ages of 1 and 6 years, and that there were no sex differences, either in the age-specific prevalence or in the level of BKV-IgG. We found no significant differences in the prevalence of BKV-IgM antibodies in healthy children and adults and pregnant women. BKV-IgM was detected in 26 of the 461 sera tested (5.6%).

Abstract
Chlamydia pneumoniae is a newly recognized common cause of respiratory tract infections. The aim of this study was to examine its prevalence in Iceland. The study was based on 1020 serum samples from individuals 0-99 years old. The samples were divided into 10-year age groups. IgG and IgM antibodies were determined with microimmunofluorescence assay. An IgG titer > or = 32 and IgM titer > or = 16 were considered positive. The prevalence of positive IgG titer in the study population was 53 +/- 16% (mean +/- SD, age group range 14-66%). Neither seasonal nor gender-based difference in IgG antibody prevalence was demonstrated. It was lowest in the youngest group, 0-9 years old (p

Abstract
In the spring of 1980, an epidemic of an illness that resembled erythema infectiosum occurred in Manitoba, Canada. We initiated prospective epidemiologic, clinical, and microbiologic studies of this illness among elementary-school children and their families. Initial microbiologic studies failed to identify the cause of the exanthem. After a similar illness associated with serologic evidence of human parvovirus infection occurred in London, stored specimens of 12 patients with exanthem were investigated for parvovirus infection. Eleven patients had parvovirus-specific IgM antibody, as did two family contacts and a teacher with nonexanthematous illnesses, and two asymptomatic family members. None of 28 children with measles or rubella had serologic evidence of recent parvovirus infection. Human parvovirus was detected by DNA hybridization and immune electron microscopy in the serum of one patient who later had a rash and in one unaffected family contact. Parvovirus DNA was also detected in the pharyngeal specimen of the teacher who was ill but did not have a rash. We conclude that human parvovirus infection can be asymptomatic or cause a variety of clinical manifestations, including nonexanthematous illness and an illness resembling erythema infectiosum.

Serologic Tests
Abstract
During an epidemic of measles in a vaccinated community, five serodiagnostic tests were performed on 67 persons on whom clinical and epidemiological data were available. The test found most suitable for a rapid diagnosis of measles infection was an Enzyme Linked Immuno Sorbent Assay for the detection of specific IgM antibodies. Only one false negative IgM was recorded. In a group of 45 persons who fulfilled the clinical definition of measles, specific IgM antibodies were detected in the acute phase serum of only 30 (66.6%), of whom 17 were vaccinated. When the convalescent sera were tested, specific IgM antibodies were detected in 25 of the 28 (89.2%) vaccinated, and in 17 of the 17 (100%) non vaccinated clinical cases. A convalescent blood should be tested in persons with a rash illness and no IgM antibodies in the acute phase serum. There were individual variations in the time of appearance of IgM. On the day of onset of rash, IgM antibodies were detected in 7 of the 12 (58.3%). A history of prior vaccination is not always associated with immunity nor with the presence of specific antibodies.

Abstract
All new cases of insulin dependent diabetes mellitus (IDDM) in children below 15 years of age were recorded prospectively during a 21-year period 1964-1984 in a defined uptake area with a relatively constant child population. The total number of children recorded was 222-111 boys and 111 girls. The number of new cases varied between 4 cases in 1968 and 20 in 1984; in 1983 seventeen new cases were recorded. Specific IgM antibodies against Coxsackie B virus (CBV), types 1-5 were measured by a reverse radioimmunoassay (RIA) technique in 24 consecutive patients collected during the period March 1982-January 1984, some of whom represented the recent period of a very high incidence of diabetes. Sixteen patients (67%) exhibited CBV IgM responses, strongly suggesting a current or recent CBV infection. The titres declined during the first few months of diabetes and seemed to be absent after the first half-year period. Among age-matched non-diabetic children scheduled for elective procedures during the same period, no cases with CBV-IgM antibodies were detected. Only three of the 16 IgM-RIA-positive patients showed a significant rise in the neutralising antibody titre against the same Coxsackie B type. It is concluded that CBV may play a pathogenetic role in induction of IDDM, and possibly more frequently so during periods with a high incidence of diabetes, at least in children below 15 years of age.

Abstract
Using a case-control design we have studied whether antibodies to cow's milk proteins are risk determinants for childhood-onset Type 1 (insulin-dependent) diabetes mellitus independent of early exposure to cow's milk formula and islet cell antibodies. Sera from 116 recent-onset diabetic children and 112 age- and sex-matched control children were analysed for cow's milk protein IgA, IgG and IgM antibodies, beta-lactoglobulin IgA and IgM antibodies and islet cell antibodies. The titres were compared to questionnaire data on duration of breast-feeding and introduction of formula feeding. Most antibody levels tended to be increased among diabetic compared to control children. This was statistically significant for cow's milk protein IgA antibodies (p less than 0.001) and beta-lactoglobulin IgA antibodies (p less than 0.01) as well as for islet cell antibody-positivity which was found among 92% of the diabetic and 3% of control children. The differences in cow's milk protein antibodies as well as beta-lactoglobulin antibodies were more pronounced among children with an early onset of Type 1 diabetes. Breast-feeding duration was significantly inversely related to the log of beta-lactoglobulin IgG (r = -0.16, p = 0.04) and the log of cow's milk protein IgA antibodies (r = -0.17, p less than 0.001). A positive correlation was found between formula feeding and the logarithm of beta-lactoglobulin IgG antibodies (r = 0.22, p = 0.01) and the log of cow's milk protein IgA antibodies (r = 0.16, p = 0.04).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
From August 27 to September 21, 1979, 58 patients fell ill with Legionnaires' disease (LD) in the town Västerås, Sweden. All patients had been staying in the town some time during 2 weeks preceding their illness, as had 10 LD patients who fell ill from mid-June to mid-August the same year. Clinically, high fever, headache, dizziness and gastrointestinal symptoms were dominating. Respiratory symptoms were moderate, radiologically verified pneumonia was seen in 59 of 64 patients examined. One patient died. The diagnosis was verified by serology, using the IFL method, in all cases. Legionella pneumophila serogroup 1 was isolated from a closed lung biopsy from 3 patients. Isolates of identical strains were made from the cooling tower on the roof of an indoor shopping centre in Västerås, visited by 57 of the patients during the incubation period.

Abstract
Nineteen patients were involved in an outbreak of infection caused by Yersinia pseudotuberculosis serotype 3. No epidemics attributable to this microorganism have been previously reported; the most extensive known cluster of cases involved four children in one family and their pet dog. The key finding in the outbreak described in the present study was the bacteriologic identification of serotype 3 in stool specimens from patients with clinically typical yersiniosis. Twelve cases were identified by isolation of Y pseudotuberculosis from stool specimens. An ELISA permitted serological diagnosis of the remaining seven cases. The antibody response was unusually slow in some patients. A noteworthy feature of the outbreak was the high incidence of postinfection complications, which developed in 10 of 19 patients. In spite of active screening of the respective families and environments of the patients, no transmitting factor was found, and the precise source of the infection remains unknown.
