Isolation and characterization of porcine parvovirus in Vietnam.

Background And Aim: No study has successfully isolated parvovirus in Vietnam. This study aimed to isolate and characterize parvovirus strains indigenous in Vietnam for vaccine development against porcine parvovirus (PPV).

Materials And Methods: We collected serum and stillbirth samples from six provinces in Vietnam, and PPV-positive samples were identified using a polymerase chain reaction.

Signal sequence contributes to the immunogenicity of Pasteurella multocida lipoprotein E.

Recombinant Pasterurella multocida lipoprotein E (PlpE) has been shown to protect against fowl cholera. This study aimed to determine if the signal sequence may contribute to the antigenicity and protective efficacy of recombinant PlpE. A small antigenic domain of PlpE (termed truncated PlpE, tPlpE) was constructed with (SP-tPlpE) or without (tPlpE) the signal sequence and evaluated in vitro and in vivo.

Comparative genomics of reveals recent importation and subsequent widespread dissemination in mariculture farms in the South Central Coast region, Vietnam.

Between 2010 and 2015, nocardiosis outbreaks caused by affected many permit farms throughout Vietnam, causing mass fish mortalities. To understand the biology, origin and epidemiology of these outbreaks, 20 . strains collected from farms in four provinces in the South Central Coast region of Vietnam, along with two Taiwanese strains, were analysed using genetics and genomics.

Isolation and characterization of strains isolated from ostriches () in Vietnam.

Background And Aim: can cause enteritis in ostriches. The toxin release is believed to play a major role in determining pathogenesis properties of these pathogenic bacteria. This study was conducted to isolate and characterize strains from ostriches in Vietnam for identifying if particular virulence factors of these pathogenic bacteria are associated with enteritis progress in ostriches.

Prevalence of virulence factor, antibiotic resistance, and serotype genes of strains isolated from pigs in Vietnam.

Aim: The study was conducted to determine the prevalence and characterization of the isolates from suspected pigs in Vietnam.

Materials And Methods: A total of 83 strains were isolated from lung samples and nasal swabs collected from pigs associated with pneumonia, progressive atrophic rhinitis, or reproductive and respiratory symptoms. Isolates were subjected to multiplex polymerase chain reaction (PCR) for capsular typing, detection of virulence-associated genes and antibiotic resistance genes by PCR.
