[fatal aeromonas sobria infection in liver cirrhosis].aeromonas sobria infection is known to be very serious in immunocompromised hosts. we report a case of a. sobria infection fatal in a subject with decompensated liver cirrhosis. a 63-year-old man with liver cirrhosis admitted for fever and vomiting developed a necrotizing soft-tissue infection in the right lower leg. despite a decompression incision in the affected limb and intensive care, he died of sepsis one day after surgery. a. sobria was detected afterward in a blood culture.201122117380
Identification of the Midgut Microbiota of An. stephensi and An. maculipennis for Their Application as a Paratransgenic Tool against Malaria.The midgut microbiota associated with Anopheles stephensi and Anopheles maculipennis (Diptera: Culicidae) was investigated for development of a paratransgenesis-based approach to control malaria transmission in Eastern Mediterranean Region (EMR). Here, we present the results of a polymerase chain reaction (PCR) and biochemical-based approaches to identify the female adult and larvae mosquitoe microbiota of these two major malaria vectors, originated from South Eastern and North of Iran. Plating ...201122163022
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

culture-based and denaturing gradient gel electrophoresis analysis of the bacterial community structure from the intestinal tracts of earthworms(eisenia fetida).the bacterial communities in the intestinal tracts of earthworm were investigated by culture-dependent and - independent approaches. in total, 72 and 55 pure cultures were isolated from the intestinal tracts of earthworms under aerobic and anaerobic conditions, respectively. aerobic bacteria were classified as aeromonas (40%), bacillus (37%), photobacterium (10%), pseudomonas (7%), and shewanella (6%). anaerobic bacteria were classified as aeromonas (52%), bacillus (27%), shewanella (12%), paeni ...201121952364
identification and molecular characterization of the interleukin-10 receptor 1 of the zebrafish (danio rerio) and the goldfish (carassius auratus l.).this is the first report of the identification and molecular characterization of an interleukin-10 receptor 1 in bony fish. by gene synteny analysis, we identified the zebrafish interleukin-10 receptor 1 (il10r1) and using this il10r1 sequence, we cloned the goldfish il10r1 cdna transcript. the identified fish il10r1 protein sequences had a putative jak1 binding site, only one of the two stat3 binding sites, that are present in all other vertebrates il10r1 proteins as well as c-terminal serine r ...201221906622
Quantification of polyphenols during retting and characterization of bacteria from the Kadinamkulam Backwaters, Kerala.The retting environment which provides a competitive niche for specialized microbes is speculated to harbour a variety of microbes with high biodegradation potential. In this context, an effort has been made to isolate and identify bacterial species having high tolerance to phenol In vitro. Maximum polyphenol (1.897 mg l(-1)) as observed during the initial period of retting, which decreased as retting proceeded. Based on biochemical characterization, the isolated bacterial strains were identifie ...201121888245
evaluation of a quantitative h(2)s mpn test for fecal microbes analysis of water using biochemical and molecular identification.the sensitivity and specificity of the h(2)s test to detect fecal bacteria in water has been variable and uncertain in previous studies, partly due to its presence-absence results. furthermore, in groundwater samples false-positive results have been reported, with h(2)s-positive samples containing no fecal coliforms or escherichia coli. false-negative results also have been reported in other studies, with h(2)s-negative samples found to contain e. coli. using biochemical and molecular methods an ...201222244995

synergies of carvacrol and 1,8-cineole to inhibit bacteria associated with minimally processed vegetables.this study assessed the occurrence of an enhancing inhibitory effect of the combined application of carvacrol and 1,8-cineole against bacteria associated with minimally processed vegetables using the determination of fractional inhibitory concentration (fic) index, time-kill assay in vegetable broth and application in vegetable matrices. their effects, individually and in combination, on the sensory characteristics of the vegetables were also determined. carvacrol and 1,8-cineole displayed minim ...201122273461
effects of graded levels of dietary methionine hydroxy analogue on immune response and antioxidant status of immune organs in juvenile jian carp (cyprinus carpio var. jian).immune response and antioxidant status of immune organs in juvenile jian carp (cyprinus carpio var. jian) fed graded levels of methionine hydroxy analogue (mha) (0, 5.1, 7.6, 10.2, 12.7, 15.3 g kg(-1) diet) for 60 days were investigated. results indicated that head kidney index, spleen index, red and white blood cell counts significantly increased with increasing mha levels up to a point (p < 0.05), whereupon decreased (p < 0.05). glutathione reductase activity in head kidney and spleen, anti-hy ...201222245840
prevalence and antimicrobial susceptibilities of vibrio, salmonella, and aeromonas isolates from various uncooked seafoods in thailand.uncooked seafood samples were collected from open markets and supermarkets in bangkok, thailand, and were examined for the presence of vibrio, salmonella, and aeromonas species from january to february 2008. from 120 samples, 272 bacterial isolates were identified through biochemical testing. of all sea bass, shrimp, oyster, and blood cockle samples (30 of each) that were processed for culture, 114 (95%) samples had at least one detectable isolate of vibrio, salmonella, or aeromonas, leaving on ...201222221354
baltic salmon, salmo salar, from swedish river lule älv is more resistant to furunculosis compared to rainbow trout.furunculosis, caused by aeromonas salmonicida, continues to be a major health problem for the growing salmonid aquaculture. despite effective vaccination programs regular outbreaks occur at the fish farms calling for repeated antibiotic treatment. we hypothesized that a difference in natural susceptibility to this disease might exist between baltic salmon and the widely used rainbow trout.201222276121
an aerolysin-like enterotoxin from vibrio splendidus may be involved in intestinal tract damage and mortalities in turbot, scophthalmus maximus (l.), and cod, gadus morhua l., larvae.vibrio splendidus is a pathogen that can cause major losses during the early stages of larval turbot rearing when live feed (rotifers or artemia) is used. as haemolytic bacteria have often been associated with larval rearing losses, we studied the role of the v. splendidus haemolysin in infection of larvae. from a bank of over 10 000 transposon mutants of v. splendidus, two different types of haemolysin-negative mutants were obtained. both had lost virulence for larval fish, and immunohistochemi ...201222233514
