Antimicrobial and disinfectant resistance of Salmonella Heidelberg from Brazili...
Bassani,Juliana; Paravisi,Mariana; Wilsmann,Daiane E.; Borges,Karen A.; Furian,Thales Q.; Salle,Carlos T.P.; Moraes,Hamilton L.S.ABSTRACT: Salmonella is a major cause of foodborne illness worldwide, and poultry and its derived products are the most common food products associated with salmonellosis outbreaks. Some countries, including Brazil, have experienced an increased prevalence of Salmonella Heidelberg among their poultry flocks. Some isolates have also presented high resistance to antimicrobial agents and persist in the poultry far...
Biofilm formation capacity of Salmonella serotypes at different temperature con...
Borges,Karen A.; Furian,Thales Q.; Souza,Sara N.; Menezes,Rafaela; Tondo,Eduardo C.; Salle,Carlos T.P.; Moraes,Hamilton L.S.; Nascimento,Vladimir P.ABSTRACT: Salmonella spp. are one of the most important agents of foodborne disease in several countries, including Brazil. Poultry-derived products are the most common food products, including meat and eggs, involved in outbreaks of human salmonellosis. Salmonella has the capacity to form biofilms on both biotic and abiotic surfaces. The biofilm formation process depends on an interaction among bacterial cells...
Evaluation of the biofilm formation capacity of Pasteurella multocida strains i...
Emery,Brunna D. de; Furian,Thales Q.; Pilatti,Roberta M.; Chitolina,Gabriela Z.; Borges,Karen A.; Salle,Carlos T.P.; Moraes,Hamilton L.S.ABSTRACT: Pasteurella multocida is a Gram-negative bacillus that causes economic losses due to the development of respiratory diseases in several animal species. Among the mechanisms of virulence, the formation of biofilms is an important factor for bacterial survival in hostile environments. Studies of biofilm formation by P. multocida are needed because P. multocida is an important pathogen involved in respir...
Classification of antimicrobial resistance using artificial neural networks and...
Rocha,Daniela T.; Salle,Felipe O.; Perdoncini,Gustavo; Rocha,Silvio L.S.; Fortes,Flávia B.B.; Moraes,Hamilton L.S.; Nascimento,Vladimir P.Avian pathogenic Escherichia coli (APEC) is responsible for various pathological processes in birds and is considered as one of the principal causes of morbidity and mortality, associated with economic losses to the poultry industry. The objective of this study was to demonstrate that it is possible to predict antimicrobial resistance of 256 samples (APEC) using 38 different genes responsible for virulence fact...
Evaluation of bursal lymphoid depletion: comparison between the conventional hi...
Salle,Carlos T.P.; Moraes,Lucas B.; Zimermann,Francielli C.; Fallavena,Luiz C.B.; Osório,Fernando S.; Salle,Felipe O.; Carvalho,DaianeAbstract: Fifty-five bursa of Fabricius (BF) were evaluated by optical microscopy for three different avian histopathologists (H1, H3 and H4) to determine the degree of lymphoid depletion. One histologist evaluated the same slides at two different times (H1 and H2) with four-months interval between the observations. The same BFs were evaluated using the system of Digital Lymphocyte Depletion Evaluation (ADDL), ...
Detection of virulence-associated genes of Pasteurella multocida isolated from ...
Furian,Thales Q.; Borges,Karen A.; Rocha,Silvio L.S.; Rodrigues,Everton E.; Nascimento,Vladimir P. do; Salle,Carlos T.P.; Moraes,Hamilton L.S.The current systems of breeding poultry, based on high population density, increase the risk of spreading pathogens, especially those causing respiratory diseases and those that have more than one host. Fowl Cholera (FC) is one such pathogen, and even though it represents one of several avian diseases that should be considered in the differential diagnosis of notifiable diseases that present with sudden death, ...
Detection of virulence-associated genes in Salmonella Enteritidis isolates from...
Borges,Karen A.; Furian,Thales Q.; Borsoi,Anderlise; Moraes,Hamilton L.S.; Salle,Carlos T.P.; Nascimento,Vladimir P.Salmonella spp. are considered the main agents of foodborne disease and Salmonella Enteritidis is one of the most frequently isolated serovars worldwide. The virulence of Salmonella spp. and their interaction with the host are complex processes involving virulence factors to overcome host defenses. The purpose of this study was to detect virulence genes in S. Enteritidis isolates from poultry in the South of Br...
Evaluation of follicular lymphoid depletion in the Bursa of Fabricius: an alter...
Moraes,Lucas B.; Osório,Fernando S.; Salle,Felipe O.; Souza,Guilherme F.; Moraes,Hamilton L.S.; Fallavena,Luiz C.B.; Santos,Luciana R.Fifty Bursa of Fabricius (BF) were examined by conventional optical microscopy and digital images were acquired and processed using Matlab® 6.5 software. The Artificial Neuronal Network (ANN) was generated using Neuroshell® Classifier software and the optical and digital data were compared. The ANN was able to make a comparable classification of digital and optical scores. The use of ANN was able to classify co...
Genes associated with pathogenicity of avian Escherichia coli (APEC) isolated f...
Rocha,Ana C.G.P.; Rocha,Silvio L.S.; Lima-Rosa,Carlos A.V.; Souza,Guilherme F.; Moraes,Hamilton L.S.; Salle,Felipe O.; Moraes,Lucas B.The virulence mechanisms of avian pathogenic Escherichia coli (APEC) have been continually studied and are believed to be multi-factorial. Certain properties are primarily associated with virulent samples and have been identified in avian isolates. In this study a total of 61 E. coli, isolates from chicken flocks with respiratory symptomatology, were probed by Polimerase Chain Reation (PCR) for the presence of ...
