In recent years, aquaculture has attained a major economic revolution, however, infectious diseases of bacterial, viral, mycotic and parasitic origin are the most significant restrictive agents in improvement intensified aquaculture, which become fast blooming seafood industry. For environment-friendly human health concerns owing to rise incidences antimicrobial resistant microbes food safety hazards, immunoprophylaxis or vaccination strategies highly effective economical protecting fish...

Abstract Trout farming is a growing aquaculture industry in Mexico, with stock mainly supplied by the importation of eyed eggs. The aim present study was to determine frequency bacterial isolations farmed rainbow trout Oncorhynchus mykiss from Mexico. Sixty-five farms distributed among seven states Mexico were included study. Individual samples gills, liver, spleen, intestine, and kidney obtained 563 apparently healthy fish. In total, 371 isolates recovered sampled fish; genera Aeromonas,...

The objective of this study was to obtain a phenotypic and genotypic profile Salmonella enterica including multidrug‐resistant (MDR) isolates from food‐producing animals clinical isolates, as well their genetic relatedness in two different States Mexico (Jalisco State Mexico). A total 243 were evaluated terms antimicrobial resistance (AMR) related genes through disk diffusion method PCR respectively; we found 16 MDR all them harbouring the blaCMY gene but not qnr genes, these represent less...

Abstract Infectious pancreatic necrosis virus (IPNV) is one of the most important viruses in Pacific salmon Oncorhynchus spp., Atlantic Salmon Salmo salar, and Rainbow Trout O. mykiss industry. This has been shown to produce high mortality among salmonid fry juveniles, survivors might become carriers. Since 2000, IPNV affected Mexican culture, resulting considerable economic losses. In current study, molecular characterization VP2 gene a number isolates was done virus's phylogenetic...

Between 2008 and 2010, 14 isolates of Avibacterium paragallinarum were identified as serovar C-1 in Mexico. All obtained from commercial laying hens suffering infectious coryza despite a history vaccination. The enterobacterial repetitive intergenic consensus-based PCR genotyping showed that all had common pattern. Until recently, serovars A-1, A-2, B-1, C-2 the prevalent Serovar has been Japan recently Americas Ecuador. Our current study suggests Av. is an emerging results also indicate...

The bacterium Ornithobacterium rhinotracheale is associated with respiratory disease in wild birds and poultry. In this study, the phylogenetic analysis of nine reference strains O. belonging to serovars A I, eight Mexican isolates serovar A, was performed. extended include sequences from another 23 available public domain. showed that 40 formed six clusters, I VI. All field were placed cluster I. One appears present genetic diversity not previously recognized a new cluster. conclusion,...

A coprological survey of enteroparasites in raptors (60 Falconiformes) from Central Mexico is reported. Three samples contained coccidian unsporulated oocysts, one Eimeria sp., trematode eggs and capillarid sp. After sporulation at the laboratory, oocysts a Falco peregrinus were identified as Caryospora neofalconis. The phylogenetic analysis C. neofalconis (GenBank accession number KT037081) showed close relationship to Australian strain RY 2014 isolate 16710 KJ634019) daceloe, with 99.2%...

The enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) technique was used for fingerprinting of reference strains and Mexican isolates Haemophilus paragallinarum. A total nine ERIC patterns were given by the serovar this bacteria. Two Modesto (C-2) from different sources showed same pattern. Seventeen obtained among 29 included in study, belonging to serovars prevalent Mexico (A-1, A-2, B-1, C-2). Obtained results indicate that ERIC-PCR could be as a...

The isolation and identification of Avibacterium paragallinarum serovar B-1 from severe infectious coryza outbreaks in broiler breeders Panama is reported for the first time. Infectious was absent over a decade breeder farms area. Disease were characterized by an up to 45% drop egg production increased mortality. Use commercial trivalent bacterin strengthened biosecurity program prevented susceptible flocks farm.

In the present study, hemagglutinating activity of seven reference strains, and nine Mexican three Danish field isolates, Gallibacterium was investigated by using fresh erythrocytes 19 different types including chicken (broiler, rooster, layer hen), turkey, pigeon, quail, duck, Harris's hawk (Parabuteo unicinctus), house finch (Carpodacus mexicanus), cow, sheep, horse, dog, rabbit, pig, human (groups A, B, AB, O; Rh+). Agglutination observed for broiler chicken, hen, pig with a subset...

The bacterium Avibacterium paragallinarum is the etiologic agent of infectious coryza chickens. There are nine serovars A. , and serovar C-1 has emerged in outbreaks layer hens Americas, with all isolates having been obtained from coryza-vaccinated In current study, clinical histopathologic outcomes experimental infections chickens were investigated. Japanese reference strain, H-18, a Mexican isolate, ESV-135, included study. No differences sign scores or morbidity observed between two...

Haemosporidian parasites of birds are found worldwide and include the genera Haemoproteus, Plasmodium Leucocytozoon. Infection with haemosporidian can affect host physical condition reproductive success. The aim this study was to identify blood parasitaemia in endemic non-endemic passerine from central Mexico highlands. This included 157 passerines representing 29 species 17 families. Overall, 30.6% (48/157) were infected parasites. Of those, Haemoproteus spp. 14.0% (n = 22), Leucocytozoon...

Dogs ( Canis lupus familiaris ) are an invasive alien species that can negatively impact natural ecosystems due to the potential of predation, competition, or disease transmission. Nonetheless, few studies assess ecological impacts these on protected areas. Our objective was determine diet free-ranging dogs, through scat analysis within Nevado de Toluca Flora and Fauna Protection Area, Estado México, Mexico. A total 130 samples from dogs were collected with help a bloodhound. Prey items...

The transmission of multidrug-resistant pathogens and antimicrobial resistance genes is an emerging problem involving multiple factors (humans, domestic animals, wildlife). aim this study was to investigate the presence Escherichia coli isolates with different from backyard poultry demonstrate in vitro transduction phenomenon these between phages migratory wild birds E. isolates. We collected 197 chickens, turkeys, ducks production units (northern region State Mexico). Isolates were...

Injection of 1 mg kg −1 2‐methylisoborneol (MIB) caused an increase in a CYP1A‐like protein approximately 56 kDa from the kidneys juvenile channel catfish as determined by western blot analysis using antibodies raised against trout CYP1A1. Ethoxyresorufin O‐deethylase activity MIB‐injected fish was significantly elevated compared to ethanol‐injected controls. Static exposure 10 ppm MIB statistically significant induction CYP2K‐like 53 livers treated CYP2K1. Treatment with ethanol (1 ml )...

Abstract The infectious pancreatic necrosis virus (IPNV) affects several species of freshwater and marine fish. In Mexico, IPNV has an important impact on farming rainbow trout Oncorhynchus mykiss; however, distribution in Mexico is unclear. diagnosis laborious; usually it based isolation tests cell culture followed by immunological identification using techniques serum neutralization, immunofluorescence, or enzyme-linked immunosorbent assay. It recently been demonstrated that reverse...
