Evaluation of the Biostimulant Activity and Verticillium Wilt Protection of an Onion Extract in Olive Crops ().

The olive tree is crucial to the Mediterranean agricultural economy but faces significant threats from climate change and soil-borne pathogens like . This study assesses the dual role of an onion extract formulation, rich in organosulfur compounds, as both biostimulant and antifungal agent. Research was conducted across three settings: a controlled climatic chamber with non-stressed olive trees; an experimental farm with olive trees under abiotic stress; and two commercial olive orchards affected by .

Use of Olive Pulp for Gestating Iberian Sow Feeding: Influence on Performance, Health Status Indicators, and Fecal Microbiota.

Olive pulp (Olea europaea) inclusion in the diet of Iberian sows (Sus scrofa) is interesting due to fiber and bioactive compounds content and because both productions are located in the same area. The aim of this trial was to study the effect of olive pulp inclusion at 100 g/kg in Iberian sow’s diet on performance, immunoglobulin and serum parameters, antioxidant status, and fecal microbiota. Forty multiparous Iberian sows (body weight (BW) = 149.

Use of Mediterranean By-Products to Produce Entire Male Large White Pig: Meat and Fat Quality.

A total of 70 male growing non-castrated pigs (Large White), with a 23.07 ± 2.87 kg average body weight (BW), were randomly allocated to three treatments in a 103 day trial: a CONTROL diet and two experimental diets, ALLIUM (5 g/kg of spp.

Antimicrobial susceptibility of Trueperella pyogenes isolated from food-producing ruminants.

A total of 96 Trueperella pyogenes isolates, an opportunistic pathogen of food-producing ruminants, obtained from cattle (n = 34), sheep (n = 35) and goats (n = 27), and identified by Real Time PCR (qPCR), were analysed to determine the susceptibility to 12 antimicrobials commonly used in livestock, using a broth microdilution. The Minimal Inhibitory Concentration (MIC) distribution was unimodal for half of the antimicrobials tested with the exception of apramycin, gentamicin, streptomycin, oxytetracycline, tylosin, and erythromycin all of which showed bimodal MIC distributions. Low MIC values for penicillin, amoxicillin, ceftiofur, enrofloxacin, and gentamicin (<1 μg/ml) were obtained, suggesting that these antimicrobials would be the most effective first line empiric treatment for T.

Paratuberculosis in dairy goat flocks from southern Spain: risk factors associated with seroprevalence.

Background: Paratuberculosis (PTB) is a chronic, enteric wasting disease of ruminants caused by subspecies (MAP), with a worldwide distribution. Andalusia, located in southern Spain, is one of the European regions with the highest goat census and the highest milk production; however, current data on the prevalence of MAP in this species are not available.

Methods: A cross-sectional study was performed to determine the seroprevalence and risk factors associated with PTB in dairy goat flocks from southern Spain.

Antimicrobial Resistance and Distribution of spp. Pulsotypes Isolated from Goat and Sheep Bulk Tank Milk in Southern Spain.

Bulk tank milk from 58 dairy goat and sheep flocks located in southern Spain was examined to determine the prevalence and distribution of . A total of 45 isolates were obtained and characterized to determine the species, antimicrobial resistance profile, and genetic similitude by pulse-field gel electrophoresis (PFGE) using I. isolates were confirmed by polymerase chain reaction (PCR) analysis of , and resistance to methicillin was determined by PCR analysis of A.

Antimicrobial susceptibility and genetic characterization of Trueperella pyogenes isolates from pigs reared under intensive and extensive farming practices.

Trueperella pyogenes is an opportunistic pathogen associated with a variety of diseases and responsible for important economic losses for pig production. Minimal Inhibitory Concentration (MIC) and Pulsed Field Gel Electrophoresis (PFGE) typing analysis were used to determine the MIC distribution and to genetically characterize a total of 180 T. pyogenes isolates obtained from slaughtered pigs reared under intensive (TpIN, n = 89) and extensive (TpEX, n = 91) farming practices.

Distribution and tracking of Clostridium difficile and Clostridium perfringens in a free-range pig abattoir and processing plant.

The presence and genetic diversity of Clostridium difficile and C. perfringens along the slaughtering process of pigs reared in a free-range system was assessed. A total of 270 samples from trucks, lairage, slaughter line and quartering were analyzed, and recovered isolates were toxinotyped and genotyped.

Susceptibility Distribution to Essential Oils of Salmonella enterica Strains Involved in Animal and Public Health and Comparison of the Typhimurium and Enteritidis Serotypes.

To determine the distribution of the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of essential oils (EOs) of cinnamon (Cinnamomum zeylanicum), clove (Eugenia caryophyllata), oregano (Origanum vulgare), common thyme (Thymus vulgaris), and red thyme (Thymus zygis) against Salmonella enterica, double serial dilutions of each EO were challenged with 85 Salmonella strains belonging to 23 serotypes of animal origin. The results showed the bactericidal character of the EOs tested against S. enterica, highlighting the oregano with MIC and MBC of 3.
