Comparative Study of Two Immunisation Protocols in Goats Using Thiol-Sepharose Chromatography-Enriched Extracts from Adult Worms.

: A comparative analysis was conducted between two immunisation protocols using different amounts of protein extracts from adult worms, purified by thiol-Sepharose chromatography (625 μg/animal vs. 200 μg/animal). These protocols involved either five or two inoculations of the immunogen, respectively.

Electrochemotherapy Intralesional Treatment in a Captive Peregrine Falcon () with Dermal Squamous Cell Carcinoma.

Captive birds of prey often exceed their wild counterparts' lifespan, as seen in bald eagles (, ~20 years wild vs. ~40 years captive), golden eagles (, ~32 years wild vs. ~46 years captive), and Andean condors (, ~50 years wild vs.

Molecular Epidemiology of Cryptosporidiosis on Lamb and Goat Kid Farms in Gran Canaria, Canary Islands (Spain).

The aim of this study was to analyse and characterise spp. in sheep and goats in Gran Canaria (Spain) and to identify the risks and economic factors related to the disease. During sampling, a semi-structured survey was conducted with farmers, and faecal samples were collected from lambs, goat kids, sheep, and adult goats from a total of 30 farms.

Molecular analysis of cryptosporidiosis on cattle farms in Gran Canaria, Canary Islands (Spain).

spp. infections in calves cause serious economic losses in livestock and pose an important zoonotic risk. The aim of this study was to investigate the prevalence of spp.

Isolation of a Novel Caprine Strain (GC) in Canary Islands and Analysis of Parasitological, Clinical, and Pathological Findings on Experimentally Infected Goat Kids.

is considered among the most pathogenic species in goats. The aim of this study was to isolate an strain and to assess its infectivity, pathogenicity, and ability to develop a protective immune response. After previous collection of -positive faeces, purification of oocysts, and amplification in donor animals, an experimental infection was carried out.

Analysis of Protection and Immune Response against in Goats Immunised with Thiol-Binding Proteins from Adult Worms.

In view of the increasing occurrence of anthelmintic-resistant strains of gastrointestinal nematodes in ruminants, various alternative control strategies have been investigated, such as those based on the induction of protective immune responses by immunisation with parasite antigens. In this study, the protective activity of somatic antigens from adult worms of purified by affinity chromatography on thiol-sepharose was analysed in goats. After challenge, the enriched products induced a slight reduction in the cumulative faecal egg counts (21%) and in the number of worms (23.

Metaphylactic strategies using toltrazuril against coccidiosis in goat kids.

Goat coccidiosis compromises animal welfare, reduces productivity and may cause mortality and delayed growth rates in goat kids around the weaning period worldwide. This field study was conducted to evaluate the efficacy of metaphylactic treatments with two doses of toltrazuril (20 or 40 mg/kg body weight - BW, p. o.

Immunoprotection against mixed Eimeria spp. infections in goat kids induced by X-irradiated oocysts.

Strategies to control goat coccidiosis traditionally rely on the use of management practices combined with anticoccidial treatments, and limited effort has been made, so far, to address immunological control of caprine Eimeria infections. Previously, we showed that monospecific immunization with X-Rad-attenuated Eimeria ninakohlyakimovae oocysts induced considerable immunoprotection upon challenge. In the present study, we conducted a similar vaccination trial but using a mixture of caprine Eimeria species typically present in natural infected goats.

Local immune response of Canarian Majorera goats infected with Teladorsagia circumcincta.

Background: Due to increased anthelmintic resistance, alternative methods to drugs are necessary to control gastrointestinal nematodes (GINs). Some of the most promising alternatives are based on the immune response of the host, such as the selection of genetically resistant breeds or the use of vaccines against these parasites. Given the limited information available on the immune response against GINs in goats, this study investigated the local immune response of goat kids of an indigenous Canary Islands breed (Majorera breed) experimentally infected with Teladorsagia circumcincta, one of the most pathogenic and prevalent GIN species.

Immune response in goats vaccinated with thiol-binding proteins from Haemonchus contortus.

The experimental protocol of immunization tested here confirms its protective effect against Haemonchus contortus in goats. This protection translated into a 65.5% mean reduction in adult worm burden after a homologous challenge, and a significant decrease (73.

Susceptibility of Malassezia pachydermatis to aminoglycosides.

Previous studies have evaluated the action of gentamicin against Malassezia pachydermatis. The aim of this study was to evaluate in vitro susceptibility of M. pachydermatis to the aminoglycosides- gentamicin, tobramycin, netilmicin and framycetin.

Humoral immune responses of experimentally Eimeria ninakholyakimovae-infected goat kids.

Although cellular immune reactions seem to be crucial for protective immune responses in Eimeria spp. infections, there are also evidences on an active involvement of the humoral counterpart. In the present study, we have analyzed the humoral response of goat kids subjected to primary and challenge infections with Eimeria ninakholyakimovae.

In vitro susceptibility testing of Malassezia pachydermatis to gentamicin.

Background: Two studies have observed that growth media containing gentamicin can inhibit the growth of the yeast organism Malassezia pachydermatis. The minimum inhibitory concentration (MIC) of this bactericidal antibiotic for this organism has not been previously determined.

Objective: To evaluate the susceptibility of M.
