An ideal vaccine against brucellosis should induce protection, not cause disease in animals or humans, and not interfere with serological diagnosis. Vaccine adjuvants can improve the immune response, leading to a more intense and prolonged protection, improving its effectiveness. The Brucella ovis ΔabcBA strain encapsulated in alginate provides an experimental vaccine formulation that protects against Brucella spp. infection. However, the investigation of other polymers such as adjuvants is important for optimizing the efficiency of the candidate vaccine B. ovis ∆abcBA. Therefore, this study aimed to evaluate the vaccine potential of the B. ovis ∆abcBA associated with different polymeric adjuvants in mice challenged with B. ovis. We observed that B. ovis ∆abcBA encapsulated by alginate with chitosan, but not copolymer Poloxamer 407, resulted in the lowest bacterial recovery in both the spleen and liver of challenged animals compared to non-vaccinated mice. While copolymer Poloxamer 407 did not induce significant humoral immune response, the alginate and chitosan vaccine formulation induced higher levels of Immunoglobulin G, with an increase in the IgG2b subclass, indicating a Th1 type of response, which is known to play a critical role in controlling infections by intracellular agents.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"60 3","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conjunctival route resulted in a shorter serological response, with all animals RBT seronegative at 12 weeks PV, compared to 57% still positive at 74 weeks PV with the subcutaneous route. LFA positivity remained high in both groups until 30 weeks PV, then decreased faster in the conjunctival group. All SHO returned to LFA negativity by 74 weeks PV.

It is one of the most commonly neglected diseases worldwide and can infect a wide range of domestic animals, including ruminants such as camels, as well as various wild species.

This study investigates the distribution of brucellosis in camels in Sudan's Kordofan States and compares several diagnostic tests, including a modified Rose Bengal Plate Test (mRBPT), Buffered Plate Agglutination Test (BPAT), Serum Agglutination Test (SAT), and a competitive Enzyme- Linkimmunosorbent Assay. A total of 388 apparently healthy camels were sampled to determine the seroprevalence of brucellosis. Forty-three (11.08%), 41 (10.56%) and 30 (7.73%) were found positive by (mRBPT), (BPAT) and (SAT) respectively. All serum samples were subsequently retested using (cELISA) as confirmatory test, which confirmed that 32 samples (8.24%) were positive. When comparing the screening tests to the confirmatory test, Cohen's kappa coefficients indicated poor agreement with cELISA: 16% for mRBPT, 32% for BPAT, and 31% for SAT. A kappa value of 40 or less is considered poor. This study highlights brucellosis prevalence in camels in Sudan's Western States and suggests targeted control measures. The data indicate that the mRBPT test is a more sensitive, cost-effective, and practical screening method compared to other agglutination tests.","PeriodicalId":23550,"journal":{"name":"Veterinaria italiana","volume":"60 3","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143658805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was designed to evaluate the thermo-stability of a live-attenuated ND virus vaccine containing the Mukteswar strain and to genetically characterize the seed virus. Moreover, the presence of extraneous agents (Fowl adenovirus, Mycoplasma, Salmonella Pullorum, and Salmonella Gallinarum) was assessed using polymerase chain reactions (PCR) optimized for detection in a panel. The vaccine was evaluated for its potency and efficacy after storage at 4°C, 25°C and 37°C for 36, 48, 96 and 144 hours. A total of 100 commercial broiler chickens were randomly divided into six groups and immunized with the vaccine stored at specified temperatures for the given times.

The data were analyzed by two-way analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA). Reverse-transcription PCR targeting the F gene of Newcastle disease virus (NDV) and subsequent sequence analysis confirmed the presence of NDV in the vaccine seed (deposited to GenBank Acc. Nos.

Phylogenetic analysis revealed a close resemblance of the vaccine virus with other Avian Avulaviruses (NDV class II Genotype III viruses and more specifically with NDV Mukteswar vaccine strains), yet it was distinct from NDV class II Pakistani field isolates, which grouped into genotype XIII.2.1. The PCR testing confirmed that the vaccine was free from extraneous agents. The present study's findings propose an alternative rapid PCR-based method to evaluate the purity of NDV live vaccines.

Characteristic histologic lesions were found in the epididymis.

In such a context, a timely, accurate, and reliable flow of information, aimed both at the population and at stakeholders, is crucial for establishing a proper dialogue between institutions and people, driving the empowerment of citizens. To address this crisis, the Italian Government introduced Law 6 of 2014, establishing a multidisciplinary Working Group tasked with identifying and mapping the sites affected by spills and illegal disposal in the territory. The TdF-WG defined a scientific methodology for classifying these sites in terms of prohibition on the cultivation of specific crops, consequently allowing the adoption of appropriate clean up and restoration measures for the impacted sites.
