Pulmonary infection on cystic fibrosis (CF) patients are associated with a limited qualitative number of microorganisms. During the colonization process, Staphylococcus aureus usually preceedes Pseudomonas aeruginosa. This latter is at first non-mucoid, being replaced or associated to a mucoid morphotype which is rare in other diseases. In 1980, Pseudomonas cepacia appeared as an important agent in CF pulmonary infections with a mean frequency of about 6.1% isolations in different parts of the world. The primus colonization mainly occurs in the presence of pre-existent tissue lesions and the clinical progress of the disease is variable. In some patients it can be fulminant; in others it can cause a gradual and slow decrease in their pulmonary functions. The concern with this germ isolation is justified by its antibiotic multiple resistence and the possibility of direct transmission from a colonized patient to a non-colonized one. We reported the first case of P. cepacia infection in a CF patient in our area. The microbiological attendance to this patient had been made from 1986 to 1991 and the first positive culture appeared in 1988. The sensitivity profile showed that the primus colonization strain was sensitive to 9 of 17 tested antibiotics, however in the last culture the strain was resistent to all antibiotics. These data corroborate the need for monitoring the bacterial flora on CF patients respiratory system.
Summary A description of a new species of Diaptomidae "Diaptomus" negrensis is given with a diagnosis. The variation of this species is very little. It has been found in various lakes at the left margin of the Rio Negro (Amazonas) near the city of Manaus. A map shows the distribution. A possible relationship with "Diaptomus" alter Herbst, 1960 is discussed but a certain relationship can't be given.
Resumo Descrição de uma nova espécie de Diaptomidae (Crustacea, Copepoda) "Diaptomus" negrensis, coletado em lagos situados à margem esquerda do rio Negro. Através de tabelas apresentadas, foi verificada uma pequena variabilidade no tamanho dos animais e no diâmetro e quantidade dos ovos. Alguns caracteres permitiram um possível parentesco com o "Diaptomus" alter Herbst, 1960.
