Antimeasles antibodies in children submitted to different vaccination schedules.

In order to study the measles antibody behavior of three vaccination schedules, 684 children were divided into 4 Groups: Group A (341 vaccinated children under the age of one); Group B (101 children at the age of one); Group C (74 children under the age of one and one at the age of one); Group D (163 unvaccinated children with a history of measles in the past-Group control). Children of Group A presented lower rates and 25.9% of the age group under two did not show any measles antibodies. In Group B, all the children presented antibodies. In Group C only 4.0% did not. In all age groups, the geometric mean HI antibody titers of Group A were lower than the values found in the other groups. The age at vaccination was the factor of greater influence on the results of this study.

[Intestinal parasite contamination of vegetables sold at supermarkets in the city of Rio de Janeiro].

Parasitological examinations were performed in material derived from 220 vegetables to detect cysts and eggs of intestinal parasites. This material was collected from supermarkets in northern and southern areas and from CEASA (Central Supply Market--40 vegetables) in Rio de Janeiro city. Vegetables proceeding from the northern areas presented a greater degree of contamination mostly of helminth eggs; lettuce was the most contaminated vegetable. The authors suggest that differences found between the northern and southern areas of the city may be due to either packing or manipulation by shop assistants and consumers.

Phyllocaulis variegatus--an intermediate host of Angiostrongylus costaricensis in south Brazil.

Molluscs collected in five localities in the State of Rio Grande do Sul (Brazil) were digested and examined. The infected slugs were identified as Phyllocaulis variegatus and the larvae found were inoculated per os into mice. After 50 days, worms with the caracteristics of Angiostrongylus costaricensis were recovered from the mesenteric arterial system. The results establish the role of P. variegatus as intermediate host of A. costaricensis in south Brazil, where many cases of abdominal angiostrongyliasis have been diagnosed.

On the diversity of mollusc intermediate hosts of Angiostrongylus costaricensis Morera & Cespedes, 1971 in southern Brazil.

Veronicellid slugs are considered the most important intermediate hosts of Angiostrongylus costaricensis, an intra-arterial nematode of rodents. Studies undertaken in three localities in southern Brazil led to identification of molluscs other than veronicellid slugs as hosts of A. costaricensis: Limax maximus, Limax flavus and Bradybaena similaris. These data indicate a low host specificity of larval stages of A. costaricensis, as it has been reported to other congeneric species.

[Dengue study in a slum area in Rio de Janeiro: preliminary analysis].

This study is part of a program to control and prevent dengue in a slum bordering on the grounds of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. The results obtained from a questionnaire and entomological survey called attention to problems pertaining to the information transmitted by public health campaigns and its interpretation, since many practices result from misunderstanding or forgetting preventive messages. Dengue-related data include most frequent vector breeding sites, people's knowledge, and dengue-related habits. The study's conclusions in terms of dengue prevention point to the need for drafting messages not only about ideal preventive practices but also teaching possible solutions: disseminating frequent messages throughout the year and not only seasonally and planning health education to join health professionals and the population in the search for sustainable dengue control alternatives.

[Evaluation of the conditions of storage of measles vaccine at the Public Health Units of Niteroi and São Gonçalo, State of Rio de Janeiro].

Twenty two "Public Health Units" were visited and evaluated as to standards of storage recommended by the Brazilian Immunization Programme. In 86.4% of the units, refrigerators were adequately or regularly maintained. However, when items such as proper inside location of the vaccines in the refrigerator or the control of temperature were checked, only 60% and 54.5% respectively presented adequate storage conditions. In 90% of the Units health workers complained of lack of immediate technical support in emergency situations. In 100% of the vaccine samples titers were well under the minimal recommended potency. Inadequacy and lack of uniformity, at regional and local levels, concerning conditions of vaccine storage as well as insufficient training of health personnel must have contributed to the above results.

[Identification of wild rodents as hosts of Angiostrongylus costaricencis in southern Brazil].

Increasing number of human cases of abdominal angiostrongyliasis has been diagnosed in the south of Brazil. The main definitive host of Angiostrongylus costaricensis in Central America is the cotton rat (Sigmodon hispidus) that does not occur in South America, except in the north of Colombia, Peru and Venezuela. Rodents were captured in the endemic area in Rio Grande do Sul (RS) and definitive hosts were identified for the first time in Brazil: Oryzomys nigripes and Oryzomys ratticeps. O. nigripes is a small wild rodent and it appears to be the main definitive host of A. costaricensis in the highlands of RS, Brazil's southernmost State.
