Porcine Epidemic Diarrhea Virus (PEDV) can infect pigs of any age, but the disease severity varies significantly, particularly affecting neonatal piglets due to their immature immune system. Various vaccination strategies have been questioned for their efficacy, especially since outbreaks have occurred even on vaccinated farms. Recent suggestions indicate that exposure to the virus may enhance the effectiveness of inactivated vaccines, highlighting the potential benefits of using attenuated viruses to generate immunity in sows without prior exposure. This study aimed to evaluate the humoral and cytokine responses in pregnant sows and their piglets after inoculation of affected piglet intestinal contents and a virus isolated. We measured immune parameters such as IL-12, IL-22, IgG, and IgA, as well as neutralizing antibodies in serum, colostrum, and milk. Notably, higher titers of neutralizing antibodies were found in sows immunized with the viral inoculum, while IL-12 and IL-22 levels showed no significant differences. Additionally, we assessed productive parameters like total piglets born, weaning mortality, average birth weight, and stillborn rates. The results indicated that sows treated with affected piglet intestinal contents had higher mortality (48.31%) and stillborn rates (20.96%) compared to those receiving the isolated virus (30.02% and 10.44%, respectively). These findings suggest that using an isolated virus can offer a safe, long-lasting, and specific immune response, underscoring the importance of thorough analysis of both systemic and mucosal immune responses against PEDV.

The research was conducted in southern Serbia, at an altitude of 600 meters, in a beech stand, on a dwarf albino specimen furher usually called Absiente pigmente fagus or just Absiente pigmente. Soil sampling and analysis were carried out at depths of 0-10 cm, 11-20 cm, and 21-30 cm. Laboratory tests included determination of the textural composition of the soil, total humus content, total nitrogen, total phosphorus and potassium, the sum of absorbed base cations, determination of hydrolytic acidity, and both active and substitutional acidity. The soil was found to have a sandy textural composition, with a strong to very strong acidic reaction and a low degree of saturation with base cations. It was further determined to be highly humic, well-supplied with total nitrogen and plant-available potassium, but poorly supplied with phosphorus. Chemical composition analyses of the leaves were simultaneously conducted on both pigmented and non-pigmented leaves. The composition of 15 macro and microelements was examined. The results showed that their concentration in albino leaves was 30% - 50% higher, except in the case of Se. The presence of heavy metals such as cadmium, chromium, and nickel was significantly higher in the non-pigmented beech tissue compared to the green tissue (38.56% for Cd, 22.97% for Cr, and 44.89% for Ni). The research was conducted for the purpose of heavy metal extraction from the soil and green restoration, and it shall continue to this end.

Climate change brings extreme events like drought, landslide, flood and anticipated more constraint to profitable livestock production causing huge economical loss in the livestock sector of the country. Deaths of livestock and damage to farms and farm infrastructure is causing a huge loss, small livestock holders are highly venerable to such climatic hazards. So to cope with these uncertain climatic hazards livestock insurance is the one of the best strategies. This study reveals that different climatic hazards is been experienced by the livestock holders of Kaski, Dolakha and Jhapa district of Nepal, 62% of the respondent has observed the change in climate. Of the total respondents perceived around 47% farmer have insured their livestock in Kaski district, 33% in Jhapa and 20 % in Dolakha district. Beside the proper vaccination, deworming, management and feeding of animals people are insuring their livestock assets due to uncertain in the climatic pattern and its consequences, this shows that livestock insurance is the one of the tool to mitigate with changing climate and climate relate hazard in livestock sector of Nepal.

The age-old battle between plants and viruses has many twists and turns. Plants acquired the RNAi factors to checkmate the viruses and the viruses encode VSRs to defeat RNAi for their own survival. Plants designed mechanisms to neutralize the toxic effects of VSRs and the viruses, in their turn, use host microRNAs to strengthen their infection processes. The infightings between these two entities will take different shapes with prolonged evolution and accordingly the researchers will dig these novel forms of duels not only to throw lights in the involved mechanisms but also to manipulate various antiviral strategies. Some of the research courses that might come up in the immediate future are discussed.

Although the veterinary art has been practiced since antiquity, the modern era began in the 18th century with the establishment of the discipline of “Veterinary Science” at universities. In the 19th century, veterinary education began in Australia with Kendall’s private veterinary school in 1888 [1]. In 1909, a Veterinary Faculty was established at the University of Melbourne and Kendall’s school was incorporated into it. In 1910, a second faculty was established at the University of Sydney and in 1936, a third was established at the University of Queensland [2-4]. A fourth school was established at Murdoch University in Western Australia (WA) in 1974 [5].

The use of novel PGPR as bio inoculant is an alternative sustainable agricultural practice to improve soil health, grain quality, increase crop productivity, and conserve biodiversity. The aim of this study is to isolate, and characterized PGP bacteria colonizing tef rhizosphere during the seedling stage. For this concern, 426 samples of tef (Eragrostis tef) rhizosphere soils and roots were collected from East Shewa zone, Oromia regional state. 200 morphologically different bacterial pure colonies were isolated and screened for their PGP traits and biocontrol properties. Among these 40.5% isolates were positive for phosphate solubilization. 36% were positive for IAA production, 4.5% were positive for ammonia production, 19 % were positive for (EXPS), 15.5% were positive for protease production, 12.5% were positive for HCN productions, 9.5 % were positive for cellulase production, 4% were positive for amylase production, 3.5% were positive for chitinase production. For abiotic stress tolerance test, all of the isolates were grown well at 20oc and 30oc and neutral pH, 27% isolates were grown well at 4oc, 25.5% grew at 40oc, 25.5% were grown well on pH-9 and pH-11, 23.5% were tolerated pH-5, 3.5% grew at 50oc and 60oc, 13.5% were grown well on 5% NaCl (w/v), 3.5% were grown well on 10 and 15% NaCl (w/v), which indicated these isolates can survive in some extreme conditions. Totally 15 bacterial species having PGP traits, biocontrol properties, and abiotic stress tolerance ability were identified using the Biolog bacterial identification system. Among these, the majority of the identified PGPR have utilized carbohydrate, carboxylic acid, and amino acid, which are the main components of plant root exudates. The above results indicated that thus PGPR can be used as biofertilizers as well as biocontrol agents to replace agrochemicals to improve crop productivity. Hence, these species can be further formulated and used for greenhouse and field applications.

Objective: To perform a review of brain biopsies in the canine species and determine if it is possible to compare the stereotactic and neuronavigation results. Method: A search was performed in NCBI’s PubMed database for stereotactic or neuronavigational canine brain biopsy publications and articles which met at least one of the inclusion criteria and not any of the exclusion criteria were selected. The inclusion criteria were: 1) assessment of the specificity of the biopsy, 2) assessment of system accuracy, 3) assessment of the biopsy results, and 4) duration of the procedure. Results: Only one article met all the inclusion criteria. Eleven articles that partially met the criteria were used for comparison. Authors used different stereotaxic methods and two used neuronavigation equipment. The authors of the stereotactic studies either adapted devices from human medicine or developed their own devices; the level of accuracy was variable (errors of 0.0 mm to 5.1 mm), and the two articles that used animals with spontaneous lesions had a diagnostic specificity rate higher than 90 percent. The accuracy of the neuronavigation studies was approximately 3.3 mm; however, no live animals were used. Conclusions: It was not possible to properly compare stereotactic and neuronavigation techniques. To do so, the methodologies and the assessed parameters need to be standardized.

Worldwide, Canine Distemper Virus (CDV) infection is a highly prevalent disease with high morbidity and mortality. CDV causes a multisystemic disease in a wide range of hosts including 9 families of mammals among them some primates, cetaceans and numerous carnivores. It presents a high tropism for lymphoid, neurological and epithelial tissue, leading to an infection of almost all systems, so the clinical signs observed are very varied. The diagnosis is made based on the clinical presentation of the disease, which considers a variety of signs and must be confirmed by a laboratory diagnostic method. The molecular technique called Reverse Transcription Polymerase Chain Reaction (RT-PCR) has been used to characterize viral strains based on the basis of genetic differences on the hemagglutinin (H) gene of CDV has allowed the identification of 14 circulating lineages in the world. Two lineages, namely the America-1 and the Europe-1/South America-1 have been described in Chile. The goal of this work was to implement a multiplex RT-PCR protocol, which was built on the in silico design of primers based on the H gene nucleotide sequences stored in the Genbank® database. This method was capable of detecting the previously described two circulating genetic lineages of CDV in a differential way providing a supporting diagnostic tool for epidemiological studies in the country. These results suggest that the primers described here are extremely selective for the above-mentioned lineages. In addition, our initial screening indicated that most analyzed clinical samples corresponded to the America-1 lineage, stressing the need for a continuous surveillance in order to properly address the prevalence of both lineages in Chile.

This study comparatively evaluated the analytical performance of the Erba H7100 hematology analyzer against the Siemens Advia 2120i and Beckman Coulter DXH 900, using 243 patient samples. The study assessed the agreement and linear relationship across 14 key hematological parameters in whole blood, employing statistical methods that included mean bias, standard deviation of the difference, Pearson’s correlation, and coefficient of determination. Additionally, reticulocyte counts were analyzed in 27 samples for Erba H7100 vs. Advia 2120i and 53 samples for Erba H7100 vs. DXH 900, revealing exceptional agreement with high Pearson’s r and r-squared values. The performance of the Erba H7100 and DXH 900 in analyzing ascitic, cerebrospinal, and bronchial wash fluids was also evaluated. Notably, the Advia 2120i analyzer exhibited discrepancies in mean corpuscular volume (MCV) and monocyte counts (Mon#). Conversely, the Erba H7100 showed better agreement with the DXH 900 for MCV and Mon# in whole blood. In fluid samples, Erba H7100 and DXH 900 demonstrated a strong correlation with Microscopy in determining Neutrophil % and Lymphocyte % values. Strong linear correlations were observed for most parameters in whole blood, with reticulocyte counts showing near-perfect correlation. This study underscores the importance of rigorous validation and potential platform-specific reference intervals to ensure accurate and reliable hematological testing, emphasizing the need for standardized methodologies in clinical laboratories.

Acute osteomyelitis (AOM) is defined as an inflammation of the bone secondary to infection. Among the most common complications of AOM is the development of a periosteal abscess and the extension of the focus locally to muscle (pyomyositis) and/or joint (osteoarthritis). However, complications with much lower incidence have been described, including deep vein thrombosis (DVT) and septic pulmonary embolisms (SPE), mainly associated with S. aureus infections. The AOM + DVT + ESP triad is a fairly uncommon entity in the pediatric population; however, if it is not diagnosed and treated in time, it implies a high morbidity and mortality. Treatment, which must be early and aggressive, includes targeted antibiotic therapy, anticoagulation, and focused control surgery. In this article, we describe the case of a 14-year-old boy with disseminated staphylococcal infection associated with the triad AOM+ DVT + SPE.
