target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
background and objectives: a number of different subtypes of avian influenza (ai) viruses have emerged in humans includingh5n1, h7n2, h7n7 and h9n2. these influenza viruses are excreted in the infected birds and in their respiratory secretions.the aim of this study was to investigate seropositivity against h9n2 and h7n7 viruses among poultry and slaughterhouse workers with occupational risk of ...
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in pigs, referred to as colibacillosis. The aim of this study was to optimize multiplex polymerase chain reaction (PCR) and immunohistochemistry (IHC) analyses of paraffin-embedded material to detect pathogenic E. coli strains causing colibacillosis in pigs. Multiplex PCR was optimized for fimbriae (F18, F4, F6, F5, and F41) and toxins (ty...
Avian Pathogenic Escherichia coli (APEC) is the contributing agent behind avian infectious disease colibacillosis, which causes substantial fatalities in poultry industries that has a significant impact on economy and food safety. Several virulence genes have been shown to be concomitant with extraintestinal survival of APEC. This study investigates antibiotic resistance patterns APEC-associate...
Postweaning diarrhea or colibacillosis is a costly disease causing substantial mortality, as well as growth retardation, in swine production.1-3 Colibacillosis is typically associated with avid intestinal adhesion and fecal shedding of enterotoxigenic Escherichia coli (ETEC). The ETEC causing diarrhea in postweaning pigs carries the F4 (K88) or F18 fimbrial antigen in most cases.4-6 The F5 (K99...
BACKGROUND The aim of our study was to investigate the possible etiology of avian colibacillosis by examining Escherichia coli isolates from fecal samples of healthy broilers. FINDINGS Seventy-eight E. coli isolates from fecal samples of healthy broilers in Japan were subjected to analysis of phylogenetic background, virulence-associated gene profiling, multi-locus sequence typing (MLST), and...
PURPOSE A virologic surveillance program for A(H7N9) virus was conducted from April 15, 2013 to February 14, 2014 in Guangzhou, aiming to clarify the geographical distribution of A(H7N9) viruses among live poultry markets (LPMs) and poultry farms in Guangzhou. Virological and serological surveys of poultry workers were also conducted to evaluate the risk of poultry-to-human transmission of the ...
