quick identification of vibrio cholerae in epidemics is   important, on the other hand; conventional methods are time-consuming and   costly. the aim of this study was to develop a rapid, inexpensive and high   sensitivity method for quick identification of vibrio cholerae . for   this purpose we designed a pcr detection based on magnetic nanoparticles for   identification of bacterial dna by p...

vibrio species are the major seafood-borne bacteria that are frequently associated with the consumption of contaminated sea food. a total of 113 samples including 58 fish and 55 shrimps were studied for the possible contamination with vibrio species. a biochemical protocol was applied for the identification of the vibrio isolates and polymerase chain reaction (pcr) was carried out to confirm th...

To assess the impact of pollution induced by pesticides on Pacific oyster, Crassostrea gigas, health in France, in vivo effects of combined pesticide exposure and bacterial challenge on cell activities and gene expression in hemocytes were tested using flow cytometry and real-time PCR. As a first step, an in vivo model of experimental contamination was developed. Pacific oysters were exposed to...

Perelleschus Wibmer & O’Brien (Curculionidae: Curculioninae: Derelomini) is revised, including the redescription of P. carludovicae (Günther) from Costa Rica and P. rectirostris Voss from Perú, as well as the addition of six new species: P. evelynae, new species, from Colombia and Panama; P. variabilis, new species, from Ecuador; P. biventralis, new species, from Ecuador; P. splendidus, new spe...

The aim of this research was to study the occurrence of Vibrio spp., Aeromonas hydrophila, Escherichia coli and Campylobacter spp. in crayfish from Azerbaijan Province using culture method and PCR assay. A total of 55 isolates were collected from 97 studied samples. Vibrio spp., A. hydrophila, E. coli and Campylobacter spp. were detected in 26 samples (26.8%), 12 samples (12.3%), 15 samples (15...

Coastal region of Chah Bahar port, Sea of Oman, was screened for the presence of bioluminescence bacteria for the first time. Water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (SWC) agar. Luminous colonies were observed after an overnight incubation at 25°C. Among twenty luminous isolates, four of them were selected for preliminary ...
