Nematode parasites of Brazilian psittacid birds, with emphasis on the genus Pelecitus railliet & Henry, 1910

In the present paper, some species of nematodes from Brazilian parrots are studied: Aproctapyrrhurae. Ascaridia hermaphrodita, A. sergiomeirai, Pelecitus circularis and P. helicinus. Single female specimens of Pelecitus sp. and Thelazia sp. are presented. The male of P. circularis is fully illustrated, for the first time, since 1884. Ascaridia sergiomeirai is also restudied 59 years after proposition. New host records are estabilished. Remarks on other species of nematodes occuring in psittacid birds are included.

Pelecitus helicinus Railliet & Henry, 1910 (Filarioidea, Dirofilariinae) and Other Nematode Parasites of Brazilian Birds

We report Pelecitus helicinus Railliet & Henry, 1910 from 13 species of birds of 2 orders and 7 families, collected from the states of São Paulo and Mato Grosso, Brazil. All 13 constitute new host records for this nematode. In addition, we report the first record of Aprocta golvani Diaz-Ungria, 1963 from Brazil and Monasa nigrifrons (Bucconidae), as well as a number of other nematode records from Neotropical birds.

Biomphalaria spp. (Preston, 1910) snails in the municipality of Juiz de Fora, Zona da Mata Mineira mesoregion, ate of Minas Gerais, Brazil

This study focuses on the geographic distribution of the snail of the genus Biomphalaria and evaluates its infectivity by Schistosoma mansoni in 5264 specimens collected in the municipality of Juiz de Fora, Minas Gerais, Brazil. Of the 31 locations studied, 6 were reservoirs, 11 rudimentary holding ponds, 7 irrigation ditches, 5 lakes, 1 ornamental pond, and 1 waterfall. Intermediate hosts were found only in the rudimentary ponds and ditches, which were 100% positive. Using morphological and molecular analysis techniques, B. tenagophila, B. peregrina, and B. straminea were identified. This is the first report of B. stramínea in the municipality, and evaluation of its infective potential revealed susceptibility of 25.4%. Although we did not find specimens of Biomphalaria infected by S. mansoni, the data obtained indicate the presence of intermediate hosts, especially in the irrigation ditches in Juiz de Fora, and their proximity to contaminated areas.

The practice of nurses caring for families of pediatric inpatients in light of Jean Watson

Objective To know the facilities and the difficulties of nurses in caring practice of hospitalized children’s families in the light of Jean Watson’s Theory of Human Caring. Method It was used the descriptive qualitative approach. The data collection was conducted in three stages: presentation of theoretical content; engagement with families in the light of Watson’s theory; and semi-structured interview with 12 pediatric nurses. The interviews were analysed using inductive thematic analysis, being possible to form three themes: Recognizing a framework for care; Considering the institutional context; and Challenges in family’s relationship. Results The theory favored reflections about self, about the institutions and about nurses’ relationship with the family of the child, normalized by a consciousness toward caring attitudes. Conclusion In this process, it is imperative that nurses recognize the philosophical-theoretical foundations of care to attend the child’s family in hospital.



Notas sobre a socialidade e a biologia de nidificação de Trypoxylon (Trypoxylon) asuncicola Strand, 1910 (Hymenoptera, Sphecidae)

Twenty-two nests of Trypoxylon asuncicola were sampled in Viçosa, State of Minas Gerais, Brazil, in January 2000 and the occupants' behavior of three nests was registered in 2h of direct observation. 528 brood cells were excavated (24±13.84 SD cells per nest), 129 were reused cells, some of them for seven times (meconium deposit count). The mean number of total cells, mean number of open and closed cells, parasitism rate and mean number of reused cells per nest were similar between old and new nests. Parasitism rate and cell reuse were associated with the number of building cells in the nest, but nest aggregate in the sampled area may play some role in the parasitism rate. Brachymeria sp. (Chalcididae) was the most important agent of brood mortality (80%). Other parasites were Melittobia sp. (Eulophidae) (17%) and a species of Icheumonidae (3%). The number of closed cells with immature individuals per nest was 4±4.2SD (N=17) and the mean reproductivity per female was 3±2.4SD (N=5). New nests produced more offspring (0 a 35%) than old nests (0 to 11%). Females and males can be found resting in the nest but copula or guarding behavior by the male was not observed. There is some evidence that in the sampled area the switch of nests by females is great and agonistic behavior between a nest owner and a visitor was not evident. Females were larger (3.9±0.4SD mm) than males (3.1±0.3SD mm) (measured as forewing length). The secondary sex ratio was 1.26 (±0.07 SE) in favor of females, which was not different from 1:1 ratio. The majority (97%) of the sampled larvae of T. asuncicola showed diapause. Some (5.1%) 'anomalous cells' were found.
