13. Notes on Ceratocystis paradoxa causing internal post-harvest rot disease on immature coconut in Brazil
Currently there is a large and increasing demand for immature coconuts for fresh consumption of their liquid endosperm (coconut water). The occurrence of post-harvest diseases prevent its sale and change the taste, making it inappropriate for consumption. In 2011, coconut fruits showing internal post-harvest rot symptoms were found in a market in Belo Horizo

14. Hemolytic and urease activities in vibrios isolated from fresh and frozen oysters
INTRODUCTION: The present study aimed to survey the Vibrio microbiota of oysters (Crassostrea rhizophorae) obtained from restaurants in Fortaleza, State of Ceará, Brazil, and to identify virulence factors. METHODS: The isolated vibrios were submitted to biochemical identification and were tested for hemolytic and urease activities. RESULTS: The isolated str

15. Ocorrência de HLB e caracterização de Candidatus Liberibacter spp. no estado do Paraná
Huanglongbing (HLB) is considered the most important disease for citrus production around the world. Three bacteria species are associated with HLB, Ca. Liberibacter africanus, Ca. Liberibacter asiaticus and Ca. Liberibacter americanus. In Brazil, the disease was first reported in 2004, in the State of São Paulo. In Parana, HLB was reported for

16. Isolation and characterization of endophytic bacteria isolated from the leaves of the common bean (Phaseolus vulgaris)
The common bean is one of the most important legumes in the human diet, but little is known about the endophytic bacteria associated with the leaves of this plant. The objective of this study was to characterize the culturable endophytic bacteria of common bean (Phaseolus vulgaris. leaves from three different cultivars (Vermelhinho, Talismã, and Ouro Negro)

17. Pathogenic variation in isolates of Pseudomonas causing the brown blotch of cultivated mushroom, Agaricus bisporus
Twenty seven bacterial isolates were isolated from superficial brown discolorations on the caps of cultivated Agaricus bisporus. After White Line Assay (WLA) and the assist of Biolog computer-identification system, isolates were divided into groups: (I) comprised ninteen bacterial isolates that positively responded to a Pseudomonas "reactans" reference strai

18. Isolation and characterization of potential lactic acid bacteria (LAB) from freshwater fish processing wastes for application in fermentative utilisation of fish processing waste
Proteolytic and/or lipolytic lactic acid bacteria (LAB) were isolated from visceral wastes of different fresh water fishes. LAB count was found to be highest in case of visceral wastes of Mrigal (5.88 log cfu/g) and lowest in that of tilapia (4.22 log cfu/g). Morphological, biochemical and molecular characterization of the selected LAB isolates were carried

19. Antibiotic resistance of Vibrio parahaemolyticus isolated from pond-reared Litopenaeus vannamei marketed in Natal, Brazil
Ten out of fifty fresh and refrigerated samples of shrimp (Litopenaeus vannamei) collected from retailers in Natal (Rio Grande do Norte, Northeastern Brazil) tested positive for Vibrio parahaemolyticus. The Kanagawa test and multiplex PCR assays were used to detect TDH and TRH hemolysins and the tdh, trh and tlh genes, respectively. All strains were Kanagawa

20. Sentinel network for monitoring in vitro susceptibility of Plasmodium falciparum to antimalarial drugs in Colombia: a proof of concept
Drug resistance is one of the principal obstacles blocking worldwide malaria control. In Colombia, malaria remains a major public health concern and drug-resistant parasites have been reported. In vitro drug susceptibility assays are a useful tool for monitoring the emergence and spread of drug-resistant Plasmodium falciparum. The present study was conducted

21. The occurrence of Aeromonas in drinking water, tap water and the Porsuk River
The occurrence of Aeromonas spp. in the Porsuk River, public drinking water and tap water in the City of Eskisehir (Turkey) was monitored. Fresh water samples were collected from several sampling sites during a period of one year. Total 102 typical colonies of Aeromonas spp. were submitted to biochemical tests for species differentiation and of 60 isolates w

22. Heterogeneity in extracellular nucleotide hydrolysis among clinical isolates of Trichomonas vaginalis
Trichomonas vaginalis is a parasitic protozoan that causes trichomonosis, a sexually-transmitted disease, with serious sequelae to women and men. As the host–parasite relationship is complex, it is important to investigate biochemical aspects of the parasite that contribute to our understanding of trichomonal biology and pathogenesis. Nucleoside triphospha

23. Ocorrência e avaliação do potencial enterotoxigênico de Staphylococcus isolados de derivados lácteos / Ocurrence and assessment of enterotoxigenic potencia of Staphylococcus isolated from dairy products
Staphylococcus are microorganisms widespread in nature and humans and animals are their main sources. Cross-contamination after milk pasteurization, caused especially by improper handling, is considered the most recurrent source of dairy products contamination by these pathogens. Staphylococus deserves our close attention due their ability to produce a large
