1. Efficacy of leptospiral commercial vaccines on the protection against an autochtonous strain recovered in Brazil
Abstract In swine and bovines, leptospirosis prevention and control is carried out via vaccination of susceptible animals using bacterins. However, the efficiency of leptospirosis vaccines has been questioned. This work aimed to investigate the potency of five leptospirosis vaccines sold commercially in Brazil, challenging the animals with one autochthonous

2. Establishment of a Pathogenicity Index for One-day-old Broilers to Pasteurella multocida Strains Isolated from Clinical Cases in Poultry and Swine
ABSTRACT Although Pasteurella multocida is a member of the respiratory microbiota, under some circumstances, it is a primary agent of diseases , such as fowl cholera (FC), that cause significant economic losses. Experimental inoculations can be employed to evaluate the pathogenicity of strains, but the results are usually subjective and knowledge on the path

3. THE USE OF ARTIFICIAL INTELLIGENCE FOR THE PREDICTION OF PRODUCTIVITY PARAMETERS IN SWINE CULTURE
ABSTRACT In similar conditions of food handling and genetics, there are large differences in the final productivity of farms, resulting from inherent factors of the production system. This fact predisposes the need of studies on optimizing the rearing conditions of the farms, in order to verify the main limitations for the producers. Therefore, the present s

4. Anti-foot-and-mouth disease virus effects of Chinese herbal kombucha in vivo
Abstract The foot and mouth disease virus (FMDV) is sensitive to acids and can be inactivated by exposure to low pH conditions. Spraying animals at risk of infection with suspensions of acid-forming microorganisms has been identified as a potential strategy for preventing FMD. Kombucha is one of the most strongly acid-forming symbiotic probiotics and could t

5. Production of leptospiral LipL32 antigen in Pichia pastoris and its use in an enzyme-linked immunosorbent assay
The production of recombinant LipL32 protein using Escherichia coli has been used extensively for the development of vaccines and diagnostic tests for leptospirosis. However, E. coli has demonstrated limitations, including low yield and lack of post-translational modifications. In this study, rLipL32 was produced in eukaryotic expression system (Pichia pasto

6. The prevalence of swine enteropathogens in Brazilian grower and finish herds
Diarrhoea among growing and finishing pigs is an important problem in many herds. The prevalence of L. intracellularis, B. pilosicoli, B. hyodysenteriae, Salmonella spp., enterotoxigenic E. coli, Trichuris suis and the occurrence of mixed infection were investigated. Fecal samples for forty-six herds with diarrhea or a history of diarrhea were randomly colle

7. In vitro biofilm forming potential of Streptococcus suis isolated from human and swine in China
Streptococcus suis is a swine pathogen and also a zoonotic agent. The formation of biofilms allows S. suis to become persistent colonizers and resist clearance by the host immune system and antibiotics. In this study, biofilm forming potentials of various S. suis strains were characterized by confocal laser scanning microscopy (CLSM), scanning electron micr

8. Molecular characterisation and biomass and metabolite production of Lactobacillus reuteri LPB P01-001: a potential probiotic
Lactobacillus reuteri LPB P01-001 was isolated from the gastrointestinal tract of wild swine and was characterised by biochemical testing and sequencing of gene 16S rRNA. A simple and low-cost culture medium based on cane sugar (2.5% p/v) and yeast extract (1% p/v) was used in the production of this probiotic. The fermentative conditions were a) pH control a

9. Detecção e isolamento de anelovírus em suínos e cultivos celulares. / Detection and isolation of anelloviruses in pigs and in cell lineages
Preliminary studies aiming the identification of possible viral agents associated with the postweaning multisystemic wasting syndrome (PMWS) revealed a possible negative association between TTSuV1 and occurrence of PMWS. Based on this finding was hypothesized that TTSuV1 might be able to inhibit the PCV2 multiplication, preventing the development of PMWS. To

10. Production biomolecule with inhibitory activity against Gram-negative bacteria isolated from faeces of broilers and swine
The aim of this study was to investigate the potential of lactic acid bacteria, bacilli and yeasts isolates to produce antimicrobial substances, especially against Gram-negative bacteria isolated from the animal faeces, searching for a new alternative to control the enteritis diseases in animal health. Evaluations were performed by microdilution in broth usi

11. BIODIGESTORES E BIOGÁS: BALANÇO ENERGÉTICO, POSSIBILIDADES DE UTILIZAÇÃO E MITIGAÇÃO DO EFEITO ESTUFA / BIODIGESTORS AND BIOGAS: ENERGETIC BALANCE, POSSIBILITING THE USE AND MITIGATION OF THE GREENHOUSE EFFECT
Biogas is a gaseous composition formed mainly by the methane gas (CH4) and by the carbon dioxide (CO2), generated especially by microbiologic processes in environment with few or no oxygen. This research was carried out on the biogas produced from the treatment of swine dejections in breathing decomposition and accumulated in the interior of biodigestors, in
