Olfactory lamellae of teleosts contain two morphologically different types of olfactory receptor neurons (ORNs): ciliated ORNs (cORNs) and microvillous ORNs (mORNs). However, little is known about the functional difference between these two types of ORNs in fish olfaction. We isolated cORNs and mORNs using a Ca(2+)-free solution method from olfactory organs of the rainbow trout and examined the...

Background: Seafood-borne Vibrio infections, often linked to contaminated seafood and water, are of increasing global public health concern. The aim of this study was to evaluate the prevalence of human pathogenic vibrios and their associated virulence genes isolated from fish and water samples from 2 commercial dusky kob farms and Kareiga estuary, South Africa. Methods: A total of 200 samples ...

The gastrointestinal (GI) microbiome in fish plays significant roles health and disease resistance. This investigation was accomplished to enumerate, characterize identify the potential probiotic bacteria from three Indian Major Carps (IMCs), viz., rohu (Labeo rohita), catla (Catla catla) mrigal (Cirrhinus mrigala) using culture dependent methods. Altogether, 105 pathogen-inhibitory (out of 121...

Responses in Atlantic salmon (Salmo salar L.) juveniles (fry) fed diets containing genetically modified maize (Bt-maize, MON810) expressing Cry1Ab protein from first-feeding were investigated during a 99-day feeding trial. Four experimental diets were made; each diet contained ∼20% maize, either Bt-maize or its near-isogenic maternal line (non-GM maize). One pair was fishmeal-based while the ot...

ABSTRACT  BACKGROUND: PIXE (Particle Induced X-Ray Emission) is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. It is very important to know which factors or probably elements act as initial seed and lead to growing the sands. The goal of this study was to compare the relative values of Fe/K, Cu/K and Zn/K for gallst...

The increasing use of pharmaceuticals has led to their subsequent input into and release from wastewater treatment plants, with corresponding discharge into surface waters that may subsequently exert adverse effects upon aquatic organisms. Although the distribution of pharmaceuticals in surface water has been extensively studied, the details of uptake, internal distribution, and kinetic process...

Heavy metals have been reported to negative impacts on the histology of fishes. In this study, impact heavy metal bioaccumulation gills, muscle and liver Oreochromis niloticus from Opa Igun reservoirs was determined by histological methods. This with a view checking for possible alterations fish organs. Live samples were collected identified in laboratory. Histological analyses carried out orga...

aim : to assess the complications of bile duct injury in laparoscopic cholecystectomy in loghman medical center, tehran. background : the incidence of complications of laparoscopic cholecystectomy has increased dramatically since the introduction and widespread use of laparoscopic cholecystectomy.  patients and methods : from january 1998 to january 2002, a total of 155 laparoscopic cholecystec...

Climate change has caused increasing Vibrio parahaemolyticus infections in areas unaffected by this pathogen. Water temperature is an important ecological factor. It consequently of high importance to follow V. aquatic environments and foods. The aim work was detect the presence Tigris River from eight different sites namely Malabadi Bridge, Fiskaya, Ongözlü Bağıvar, Pamukçay, Ambarçay, Seyrant...
