AVALIAÇÃO MICROBIOLÓGICA DE HORTALIÇAS E FRUTAS MINIMAMENTE PROCESSADAS COMERCIALIZADAS EM FORTALEZA (CE)

Avaliou-se a qualidade microbiológica de 15 amostras de hortaliças/tubérculos e de 15 amostras de frutas minimamente processadas, comercializadas em Fortaleza (CE). Foram realizadas análises de coliformes fecais e totais, pesquisa de Salmonella sp., contagem total de bolores e leveduras, contagem de Staphylococcus coagulase positiva e contagem total de psicrotróficos. Detectou-se a presença de Salmonella em 66,6% das amostras de hortaliças/tubérculos e em 26% das de frutas. Foi verificado que 13,3% das amostras de hortaliças/ tubérculos apresentaram contagem de coliformes fecais acima do limite estabelecido pela legislação brasileira. Contagens elevadas de coliformes totais, de bolores e leveduras e de psicrotróficos também foram encontradas em ambos os produtos, indicando condições inadequadas de higiene durante o processamento, comprometendo seu armazenamento e sua qualidade microbiológica. MICROBIOLOGICAL EVALUATION OF VEGETABLES AND FRUITS MINIMALLY PROCESSED MARKETED IN FORTALEZA (CE) Abstract The microbiological quality of 15 vegetables and 15 fruits minimally processed samples marketed in Fortaleza - CE (Brazil) was evaluated. The following analyses were carried out: total and fecal coliforms, Salmonella sp., total yeasts and moulds count, coagulase positive Staphylococcus count and total psychrotrophics count. Salmonella was detected in 66.6% of vegetable samples and 26% of fruit samples. Fecal coliforms count higher than legislation limit, it was verified in 13.3% of vegetable samples. High counts of total coliforms, yeasts and moulds and psychrotrophics were also found on both products, showing inadequate hygiene conditions during manufacturing, affecting storage and microbiological quality of minimally processed fruits and vegetables

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Perfil de contaminação por Staphylococcus e suas enterotoxinas e monitorização das condições de higiene em uma linha de produção de queijo de coalho Contamination profile for staphylococci and its enterotoxins and monitorization of the conditions of hygiene in a ‘coalho' cheese production line

Avaliou-se o perfil de contaminação por Staphylococcus e suas enterotoxinas e monitorou-se as condições de higiene em uma linha de produção de queijo de coalho por meio da técnica de bioluminescência (ATP). A população de Staphylococcus sp. variou de This research aimed to evaluate the contamination by staphylococci and its enterotoxins as well as to monitor the conditions of hygiene from a coalho cheese production line, using ATP bioluminescence assay. Staphylococcus sp. population varied from <1CFU mL-1, in pasteurized milk to 1.5 x 107CFU mL-1, in raw milk, whereas coagulase-positive staphylococci count ranged from <1CFU mL-1, in pasteurized milk to 5.0 x 106CFU mL-1 in raw milk. Coagulase-positive staphylococci were detected in 100% (25/25) of the raw milk samples and in 8% (2/25) of cheese samples. Twelve Staphylococcus species were identified within the selected 68 isolates, being nine negative and three positive for coagulase. Raw milk samples showed a high rate of coagulase-positive, being S. aureus the most common, whereas other product samples and equipment surfaces, pieces of furniture, utensils and manipulator gloves samples presented a high frequency of coagulase-negative and low frequency of coagulase-positive. Staphylococcal enterotoxin was detected in 20% of the raw milk samples and therefore in pasteurized milk, curd and cheese. ATP measurement permitted to assess the effectiveness of the surfaces cleaning, being considered adequate in 62.1% (36/95), "alert state" in 23.2% (22/95) and inadequate in 14.7% (14/95) of surfaces evaluated. Detection of staphylococci species with enterotoxigenic potential as well as enterotoxin presence reveal dissemination of contamination at the "coalho" cheese production line, possibly due inappropriate Good Manufacturing Practices (GMP) from the initial milking step until the final cheese production

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
