a chitinase from aeromonas veronii cd3 with the potential to control myxozoan disease.the class myxosporea encompasses about 2,400 species, most of which are parasites of fish and cause serious damage in aquaculture. due to the concerns about food safety issues and limited knowledge of myxozoa life cycle and fish immune system, no chemicals, antibiotics or immune modulators are available to control myxozoa infection. therefore, little can be done once myxozoa establishment has occurred.201122205999
Do alternate bacterial indicators and pathogens increase after centrifuge dewatering of anaerobically digested biosolids?The objectives of this research were to evaluate the potential for sudden increase and/or regrowth of alternative bacteria as either indicators or pathogens after dewatering of thermophilic and mesophilically digested biosolids. The results showed that, in general, for thermophilic processes, even when a statistically significant (p < 0.05) sudden increase and regrowth occurred for fecal coliforms, Escherichia coli, and Enterococci, it did not occur for Salmonella or Aeromonas. For the mesophili ...201122195428
phylogenetic characterization of bacteria in the gut of house flies (musca domestica l.).house flies (musca domestica l.) are cosmopolitan, ubiquitous, synanthropic insects that serve as mechanical or biological vectors for various microorganisms. to fully assess the role of house flies in the epidemiology of human diseases, it is essential to understand the diversity of microbiota harbored by natural fly populations. this study aimed to identify the diversity of house fly gut bacteria by both culture-dependent and culture-independent approaches. a total of 102 bacterial strains wer ...201122092755
