Enteroaggregative Escherichia coli (EAEC) has been reported to cause traveler's diarrhea and persistent diarrhea in children in developing countries and in immunocompromised patients. To clarify the prevalence of EAEC in traveler's diarrhea, we studied 636 US, Canadian, or European travelers with diarrhea: 218 in Guadalajara, Mexico (June--August 1997 and 1998), 125 in Ocho Rios, Jamaica (Septe...

Bovine viral diarrhea viruses (BVDV) are members of the Pestivirus genus within the family Flaviviridae. Based on antigenic and nucleotide differences, BVDV are classified into two recognized species, BVDV-1 and BVDV-2. More recently, a new putative pestivirus species, tentatively called "HoBi-like", has been associated with bovine viral diarrhea. HoBi-like viruses were first identified in feta...

abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...

Abstract A hedonic model was employed to examine factors impacting feeder cattle prices at a monthly video auction in Tennessee. Home-raised were estimated have $2 per cwt. premium and that been tested for PI-BVDV (persistent infections with bovine viral diarrhea virus) sold of $1.19 We also show how price varies across sale months steers heifers, suggesting opportune times market gender-specif...

Escherichia coli strains causing postweaning diarrhea (PWD) and edema disease (ED) in pigs are limited to a number of serogroups, with O8, O45, O138, O139, O141, O147, O149, and O157 being the most commonly reported worldwide. In this study, a DNA microarray based on the O-antigen-specific genes of all 8 E. coli serogroups, as well as 11 genes encoding adhesion factors and exotoxins associated ...

in order to study the seroprevalence of pestivirus infection in small ruminants of ahvaz at khouzestan province of iran, 148 sheep sera and 143 goat sera were randomly collected and tested by seroneutralization. seroneutralization was performed by nadl strain of bovine viral diarrhea virus genotype 1. the results indicated the overall seroprevanelces of 46.62% in sheep and 32.871% in goats. pre...

Characterisation of a new infectious full-length cDNA clone of BVDV genotype 2 and generation of virus mutants Novel BVDV-2 mutants as new candidates for modified live vaccines New insights into processing of bovine viral diarrhea virus glycoproteins Erns and E1

Bovine viral diarrhea (BVD) is a disease that affects cattle and other ruminants worldwide causes considerable economic losses. A cross-sectional study was carried out between December 2017 July 2018 with the aim to estimate prevalence of Viral Diarrhea virus (BVDV) antibodies identify potential risk factors associated occurrence in dairy peri-urban areas Gondar city, Northwest Ethiopia. total ...

Bovine viral diarrhea virus (BVDV) is one of the most important viral pathogens of cattle worldwide. The aim of present study was to determine the molecular characterization and phylogenetic analysis of BVDV infection in dairy herds of Fars province, Iran. For initial screening, a total of 400 blood samples were collected from 12 industrial dairy herds with previous history of diarrhea, abortio...
