Prevalence of Toxocara spp. and other parasites in dogs and cats in Halifax, Nova Scotia.

Several cases of visceral larva migrans syndrome in children led to an investigation of the ova of Toxocara spp. and other species in stool specimens from stray dogs and cats in Halifax, Nova Scotia. Fecal samples from 474 stray dogs and 299 stray cats were examined. Ova of Toxocara canis or cati were present in stools from 26.6% of the dogs and 25.1% of the cats. In dogs the prevalence of Toxocara canis was noticeably greater in puppies (56.1%) than in mature animals (11.9%).

Prevalence of recurrent herpes labialis and aphthous ulcers among young adults on six continents.

The prevalence of recurrent herpes labialis (RHL) and recurrent aphthous ulcers (RAU) in young adults - - 635 armed-forces recruits and 9897 health-profession students - - in 48 institutions in 21 countries was determined by a questionnaire survey. Two or more occurrences (lifetime prevalence) of RHL were reported by 33.2% of men and 28.0% of women; the corresponding figures for RAU were 38.7% and 49.7%. North American respondents, mainly from Canada, had a significantly higher prevalence of both lesions. There were some differences in relation to profession. Approximately 15% of all the people surveyed had had herpes labialis and 25% had had aphthous ulcers at least once during the previous year. Persons with a history of recurrence of one lesion were more likely to have a history of recurrence of the other.

Virusemenia after cytomegalovirus mononucleosis.

Cytomegalovirus (CMV) was demonstrated for 15 months in semen from a male homosexual with a recent history of a mononucleosis-like illness. The male urogenital tract can harbor CMV for long periods, and sexual transmission of the virus is more likely in persons with multiple heterosexual or homosexual contacts.

Survey of a neonatal population for the prevalence of cytomegalovirus.

A neonatal population of 542 was tested for cytomegaloviruria. 293 were normally grown and full term, 172 normally grown but premature, and 77 were undergrown. Two normally grown term infants and one premature were excreting the virus (o.55%). Only one, a normally grown term infant, had signs of classical cytomegalic inclusion disease. None of the undergrown infants was infected.

The occurrence of hepatitis-associated antigen in a group of Canadian patients with leukemia.

Serial blood samples from 37 Nova Scotian patients with different forms of leukemia and other malignant conditions of bone marrow and lymphoid tissue were tested for the hepatitis-associated antigen (HAA). Ten patients were found to be positive for HAA. Not only is there an increased incidence of HAA in this population group, but when present the antigen is carried for a longer period than in the normal individual. The increased incidence was completely unrelated to the blood transfusion histories of the patients.

Congenital cytomegalovirus infection: clinical, pathological and virological studies of two fatal cases.

Two infants severely ill at birth as a result of congenital cytomegalovirus infection were born in Halifax, Nova Scotia, in April and July 1968. Both died within seven weeks. Clinical, pathological and virological studies including serology and electron microscopy were made both before and after death. Cytomegalovirus was isolated in tissue culture from urine specimens from both infants during life and from organ tissues, blood and ascitic fluid after death. Large inclusion-bearing cells mixed with the erythrocytes and leukocytes were seen within the lumina of pulmonary blood vessels. A brief general discussion is presented of the various clinical manifestations of congenital cytomegalovirus infection and of the different serum antibody patterns found in these two pairs of mothers and infants.

Prevalence of cytomegalovirus infection in a normal urban population in Nova Scotia.

During 1967 and 1968 a seroepidemiological survey was conducted on the prevalence of CF antibodies to CMV in the normal population of the Halifax-Dartmouth metropolitan area of Nova Scotia. Samples of 550 sera, collected from all age groups, including newborns, were processed. At birth, 34% of infants possess antibodies, presumably of maternal origin, and there follows a decline until at 2 years of age only 4% of children exhibit evidence of infection. There is a gradual increase up to 16% by 20 years of age, and thereafter this is maintained until by 40+ years half the population possesses antibodies.A more detailed analysis of cord sera indicated that approximately 60% of women of childbearing age possess no antibodies and are susceptible to primary CMV infection. Among these, age and gravidity are not significant factors.These data indicate that CMV infection is fairly widespread in this community, although comparative studies suggest that it is less so than in some other areas, such as Easter Island, where a more homogeneous pattern of overcrowding and poor sacioeconomic conditions prevails.
