Exploring the Prevalence and Resistance of in Urban Bird Populations.

The increasing urbanization of ecosystems has had a significant impact on wildlife over the last few years. Species that find an unlimited supply of food and shelter in urban areas have thrived under human presence. Wild birds have been identified as amplifying hosts and reservoirs of worldwide, but the information about its transmission and epidemiology is still limited.

Prevalence and antimicrobial resistance of Campylobacter from wild birds of prey in Spain.

Wild birds have been identified as a relevant reservoir of Campylobacter spp., therefore, a potential source of infection in humans and domestic animals. The objective of this study was to determine the occurrence of Campylobacter spp.

Oropharyngeal Trichomonosis Due to Trichomonas gypaetinii in a Cinereous Vulture ( Aegypius monachus) Fledgling in Spain.

A juvenile Cinereous Vulture ( Aegypius monachus) fledgling was found disorientated on the roof of a building in Madrid City, Spain, in October 2016. A veterinary examination revealed multiple plaques distributed throughout the oropharyngeal cavity. Lesions were located under the tongue and at the choanal slit, hard palate, and esophagus opening and ranged from 2 to 7 mm, coalescing in areas up to 2 cm, with a yellowish color of the surface.

Colonization with Enterobacteriaceae-Producing ESBLs, AmpCs, and OXA-48 in Wild Avian Species, Spain 2015-2016.

Antibiotic resistance is a global threat of complex and changeable epidemiology. The role of wild birds in the dissemination of antibacterial resistance might be underestimated. We studied the cloacal colonization by cefotaxime-resistant Enterobacteriaceae in 668 wild birds in Spain.

Impact of human-associated Escherichia coli clonal groups in Antarctic pinnipeds: presence of ST73, ST95, ST141 and ST131.

There is growing concern about the spreading of human microorganisms in relatively untouched ecosystems such as the Antarctic region. For this reason, three pinniped species (Leptonychotes weddellii, Mirounga leonina and Arctocephalus gazella) from the west coast of the Antartic Peninsula were analysed for the presence of Escherichia spp. with the recovery of 158 E.

Distinct Campylobacter fetus lineages adapted as livestock pathogens and human pathobionts in the intestinal microbiota.

Campylobacter fetus is a venereal pathogen of cattle and sheep, and an opportunistic human pathogen. It is often assumed that C. fetus infection occurs in humans as a zoonosis through food chain transmission.

Effect of Feed Form and Whole Grain Feeding on Gastrointestinal Weight and the Prevalence of Campylobacter jejuni in Broilers Orally Infected.

Two independent trials were carried out to evaluate the effect of feed form, whole wheat (WW) and oat hulls (OH) addition on gastrointestinal (GIT) weight and Campylobacter jejuni colonization in orally infected birds. In Trial 1, there were six treatments factorially arranged with two feed forms (mash vs pellets), and three levels of WW from 1-21/22-42d: 0/0, 7.5/15%, 15/30%.

Fluorescent microbead-based immunoassay for anti-Erysipelothrix rhusiopathiae antibody detection in cetaceans.

A fluorescent microbead-based immunoassay (FMIA) for detection of anti-Erysipelothrix rhusiopathiae antibodies in pigs was adapted for use in cetaceans. The FMIA was validated and adjusted using serum samples from 10 vaccinated captive bottlenose dolphins Tursiops truncatus collected between 1 and 13 mo after immunization. The technique was then used to analyze specimens from 15 free-ranging cetaceans stranded alive on the Valencian Mediterranean coast between 2006 and 2014: 11 striped dolphins Stenella coeruleoalba, 3 Risso's dolphins Grampus griseus and 1 bottlenose dolphin Tursiops truncatus.

Isolation of a point mutation associated with altered expression of the CmeABC efflux pump in a multidrug-resistant Campylobacter jejuni population of poultry origin.

The objective of this study was to investigate the antibiotic resistance phenotype of Campylobacter jejuni isolates from a poultry flock of broiler production in Spain. Isolates were characterised by RFLP-PCR of the flaA gene and multilocus sequence typing. Minimum inhibitory concentrations of quinolones, aminoglycosides, β-lactams, tetracyclines, phenicols, macrolides and lincosamides were determined by Etest.

Health impact evaluation of alternative management systems in vicuña (Vicugna vicugna mensalis) populations in Peru.

To determine the impact of farming over vicuña population in Peru, serum samples were collected from 207 vicuñas (126 captive vicuñas and 81 free-ranging vicuñas) and 614 domestic South American camelids (571 alpacas and 43 llamas), in ten Andean communities at the Salinas y Aguada Blanca reserve, province of Arequipa, southern Peru. Samples were tested for the presence of leptospirosis, foot and mouth disease (FMD), bovine viral diarrhea (BVD), bovine herpesvirus type 1 (BHV-1), brucellosis, bluetongue disease (BT), paratuberculosis, and neosporosis. Serological results showed that 1.

Differences in the prevalence of Tritrichomonas foetus infection in beef cattle farmed under extensive conditions in northern Spain.

Bovine trichomonosis (BT) is a sexually transmitted disease of cattle caused by infection with Tritrichomonas foetus. In a recent study, T. foetus infection was detected in 41.

Detection of a novel genotype of Cryptosporidium in Antarctic pinnipeds.

A study was conducted to investigate the presence of Cryptosporidium and Giardia in Antarctic marine mammals. A total of 270 faecal samples from different species of pinnipeds from different locations in the South Shetland Islands and Antarctic Peninsula were analysed by immunofluorescence microscopy and PCR. Cryptosporidium was detected by PCR in three samples from Southern elephant seals (Mirounga leonina) and 2 Weddell seals (Leptonychotes weddellii).

Detection of Toxoplasma gondii antibodies in Antarctic pinnipeds.

The presence of Toxoplasma gondii antibodies was investigated in Antarctic marine mammals. Two hundred and eleven sera from different species of pinnipeds collected in years 2007, 2010 and 2011 from different locations in the South Shetland Islands and Antarctic Peninsula were analysed using a commercially available agglutination test kit. The presence of antibodies (titres ≥ 1:25) against T.

High prevalence of Tritrichomonas foetus infection in Asturiana de la Montaña beef cattle kept in extensive conditions in Northern Spain.

Bovine trichomonosis (BT) and bovine genital campylobacteriosis (BGC) are sexually transmitted diseases that can be important infectious causes of reproductive failure in extensively managed beef cattle where natural mating is a common practice. However, their prevalence in Europe was thought to be insignificant or very low. The purpose of this study was to investigate the prevalence and risk factors associated with BT and BCG in a representative beef cattle breed, Asturiana de la Montaña (AM), which is usually managed extensively in the mountain areas of Northern Spain and putative risk factors associated with the two diseases are present on most farms holding AM cattle.

Drinking water as the source of Campylobacter coli infection in grandparent heavy breeders.

The aim of the present study was the molecular identification of a common source of infection of Campylobacter coli in two grandparent breeder farms. Campylobacter jejuni and C. coli were isolated from well water and cloacal swabs from grandparent chickens.

Presence of Listeria, Arcobacter, and Campylobacter spp. in dairy farms in Spain.

Bacteria from genera Listeria, Campylobacter and Arcobacter are potentially zoonotic pathogens for humans and they may be detected in dairy cattle farms. In this study the presence of these bacteria was considered in dairy cattle farms in Galicia (northwest of Spain). In the first part of the study, bulk tank milk samples were collected to determine the herd prevalences of Listeria spp.
