Characterization of the commercial fish production landed at Manaus, Amazonas State, Brazil

The present work aims to update a series of information about the regional fishing production, by presenting and characterizing the contribution of the different sub-systems of the Amazon basin to the catch landed at the main fishing market of Manaus, Brazil, from 1994 to 1996. Collectors specifically hired for this function registered key information on the fisheries. Thirty nine types or groups of fish were found in the fishing production landed. Jaraqui (Semaprochilodus spp.), curimatã (Prochilodus nigricans), pacu (Myleinae), matrinchã (Brycon cephalus), sardine (Triportheus spp.), aracu (Anostomidae) and tambaqui (Colossoma macropomum) were the most important items during three consecutive years. In 1994 these items summed up 91.6% of the total production; in 1995 and 1996 these values were, respectively, 85.3% and 86.4% of the total production. Tambaqui landed decreased remarkably during the period 1976-1996. There was a strong seasonal component in the production of the main species; jaraqui and matrinchã were mostly landed between April and June, while curimatã, pacu, and sardine were mostly landed during the dry season. Other important items showed a strong inter-annual variation in their production. The fishing production landed came mostly from the sub-system of the Purus River (around 30% of the total production). The subsystem of the Medium-Solimões contributed with an average of 15% and the sub-systems of the Madeira, Lower-Solimões, Upper-Amazon and Juruá, together contributed with 11.5% of the total production landed. Finally, the remaining sub-systems contributed with only 7.6% of the production.

Enterococcus spp. em espécimes clínicos de pacientes atendidos em unidades de terapia intensiva

The relationship between the occurrence of enterococci in the oral microbiota and serious infections in patients hospitalized in intensive care units (ICU) has been established. This study evaluated the presence of Enterococcus faecalis and other species of this genus in the mouths of patients on ICU, correlating it with oral and systemic conditions. Data on health and socioeconomic, medication use, medical and family history of patients maintained for 72 hours in the ICU, diagnosed with severe infection or who have developed this condition after the entry to the unit were obtained. Fifty patients provided intraoral and extraoral clinical samples for analysis (above and subgingival biofilm, saliva and buccal mucosa, followed by obtaining samples of respiratory secretions for patients with pneumonia, and blood and urine for sepsis). The presence of target microorganisms was performed by polymerase chain reaction (PCR) and culture using selective media. The chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients showed poor. E. faecalis was significantly more frequent microorganism, followed by E. faecium. The use of broadspectrum antimicrobial action was associated with the presence of these opportunistic microorganisms. These bacteria were more frequent in patients with periodontitis or gingivitis. The results showed that enterococci associated with serious infectious processes may originate from resident microbiota of patients and its prevalence is not elevated in healthy individuals.

Ceratoconjuntivite por Encephalitozoon hellem em periquitos agapornis (Agapornis spp.) no Brasil: relato de caso

Relata-se um caso de ceratoconjuntivite causada por Encephalitozoon hellem em agapornis (Agapornis spp.) adultos, provenientes de um criatório comercial. Cinco animais apresentaram sinais clínicos de ceratoconjuntivite, blefaroespasmo e blefaroedema bilateral, com presença de secreção seropurulenta. Amostras fecais foram colhidas e foi realizado exame coproparasitológico, com resultado negativo. Dois animais foram necropsiados, sendo detectados, em impressões de raspado de conjuntiva ocular, esporos e outros estádios evolutivos de Microsporidium. A confirmação do diagnóstico foi feita pela reação em cadeia de polimerase e sequenciamento de fragmentos amplificados, com utilização de primers específicos para o gene da subunidade 18S do rRNA de E. hellem. A análise dos fragmentos amplificados demonstrou 100% de similaridade com outras sequências de E. hellem publicadas no GenBank. Este é primeiro relato de infecção por E. hellem em aves no Brasil.
