Condenações de carcaça suínas devido a doenças respiratórias revisão bibliográfica

As doenças respiratórias são um problema significativo na produção suína e podem levar à condenação de carcaças no abate. Entre os agentes causadores dessas doenças destacam-se o Actinobacillus pleuropneumoniae, Mycoplasma hyopneumoniae e a Pasteurella multocida. O Actinobacillus pleuropneumon...

Effect of parity segregation on Mycoplasma hyopneumoniae infection dynamics and pneumonic lesions in pigs

Ciênc. rural (Online); 52 (2), 2022
Gilts represent a group risk for Mycoplasma hyopneumoniae vertical transmission in swine herds. Therefore, parity segregation can be an alternative to control M. hyopneumoniae infections. The study evaluated the effect of parity segregation on M. hyopneumoniae infection dynamics and occurrence and severi...

Causes of death in growing-finishing pigs in two technified farms in southern Brazil

Pesqui. vet. bras; 40 (10), 2020
The aim of this study was to investigate the main causes of death in growing-finishing pigs in southern Brazil. During a one-year period (from 2018 to 2019), two industrial pig herds (18 and 20 thousand pigs each farm) in southern Brazil were monitored along the four seasons of the year (12 days per seas...

Genetic diversity of Mycoplasma hyopneumoniae in Mendoza province

Rev. argent. microbiol; 51 (3), 2019
En Argentina, la neumonía enzoótica porcina (NEP) es altamente prevalente y se han identificado diferentes tipos genéticos de Mycoplasma hyopneumoniae. Sin embargo, se carece de información acerca de la prevalencia de NEP y de otros aspectos epidemiológicos de esta entidad en la provincia de Mendoza...

Occurrence of Mycoplasma hyopneumoniae in slaughter pigs from Southern Brazil

Mycoplasma hyopneumoniae is the causative agent of enzootic pneumonia (EP), a disease that is highly prevalent and globally distributed, causing significant economic losses to the swine industry. Disease progression is characterized by reduced feed conversion and the development of lung lesions. Consider...

Persistence of the same genetic type of Mycoplasma hyopneumoniae in a closed herd for at least two years

Rev. argent. microbiol; 50 (2), 2018
Two cross-sectional studies were carried out in 2013 and 2015 monitoring for Mycoplasma hyopneumoniae presence in a swine farm. In these studies, the genetic diversity of M. hyopneumoniae was assessed in clinical specimens using a Multiple Locus Variable-number tandem repeat Analysis (MLVA) targeting P97...

Parenteral adjuvant potential of recombinant B subunit of Escherichia coli heat-labile enterotoxin

Mem. Inst. Oswaldo Cruz; 112 (12), 2017
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin (LTB) is a potent mucosal immune adjuvant. However, there is little information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a parenteral adjuvant using ...

Mycoplasma hyorhinis infection in early cases of mycoplasmal pneumonia in swine and evaluation of diagnostic assays

Pesqui. vet. bras; 37 (10), 2017
Mycoplasmal pneumonia is an important disease in the pig industry. Due to the controversial role of Mycoplasma hyorhinis in this disease, confirmation of the presence of this bacterium and the identification of its roles in respiratory disease remain major challenges. The objectives of this study were to...

Association of number of tandem repeats in two important adhesins in Mycoplasma hyopneumoniae

Diversidade genética de Mycoplasma hyopneumoniae tem sido relatada em análise múltipla de repetições em tandem em número variável (MLVA). O objetivo deste estudo foi descrever a distribuição espacial e a heterogeneidade genética de tipos de M. hyopneumoniae no Brasil, bem como investigar a corr...
