[Ab] Resumo:Ornithobacterium rhinotracheale (ORT) has been considered exotic to New Zealand and thus, any samples from poultry suspected of ORT infection are submitted as part of an exotic disease investigation managed by Ministry for Primary Industries (MPI) and subjected to standardized test protocols carried out in the physical containment level 3+ laboratory at MPI's Animal Health Laboratory (AHL). All previous exotic disease investigations concerning ORT produced negative results by bacterial culture and conventional PCR. Following the recent introduction of a real-time PCR for ORT at the AHL, several tracheal wash fluids from backyard chickens ( Gallus gallus domesticus ) were tested positive. This identification constituted the first detection of ORT in New Zealand poultry. As a result, a second premise was investigated with further samples testing positive for ORT by molecular assays. This paper describes the two exotic disease investigations associated with the first detection of ORT in New Zealand poultry and its implications.

[Ab] Resumo:The bacterium Ornithobacterium rhinotracheale is associated with respiratory disease and septicemia in poultry. In this study, 9 reference strains and a total of 23 isolates of O. rhinotracheale from respiratory diseased poultry from Mexico were serotyped and genotyped. Furthermore, the antimicrobial susceptibility of isolates and reference strains of O. rhinotracheale were determined. All isolates belong to serotype A and showed a clonal relationship. All reference strains and isolates were resistant to colistin, fosfomycin, gentamicin, kanamycin, streptomycin, and trimethoprim-sulfamethoxazole. These results should eventually be helpful in planning strategies for the control of O. rhinotracheale infections in poultry in Mexico.

[Ab] Resumo:The coinfection of Avibacterium paragallinarum and Ornithobacterium rhinotracheale in two outbreaks of infectious coryza from Peru is reported. The diagnosis was confirmed by bacteriologic isolation, PCR testing, and sequencing of the 16S rRNA gene. The susceptibility of the isolates to 12 antimicrobial agents was tested by a disk diffusion method. The isolates were susceptible to amoxicillin/clavulanic acid and florfenicol and were resistant to oxacillin and sulfamethoxazole/trimethoprim. The coinfection of Av. paragallinarum and O. rhinotracheale and the severity of clinical signs were evaluated by experimental infection of specific-pathogen-free chickens. The group inoculated with O. rhinotracheale alone presented minimal clinical signs in 3 of 10 chickens. However, the groups inoculated with both Av. paragallinarum and O. rhinotracheale induced the most-severe clinical signs compared with the group inoculated with Av. paragallinarum alone. In conclusion, coinfections with Av. paragallinarum and O. rhinotracheale may occur, and these outbreaks could be more severe than single infections. Hence, the prevention, control, and diagnosis of Av. paragallinarum with O. rhinotracheale are important in outbreaks of infectious coryza.

[Ti] Título:Molecular Characterization of the Recently Emerged Poultry Pathogen Ornithobacterium rhinotracheale by Multilocus Sequence Typing.

[Ab] Resumo:Ornithobacterium rhinotracheale (ORT) is an economically important bacterial pathogen of turkeys and chickens worldwide. Since its first detection, a variety of typing methods have been used to gain basic knowledge about the bacterial population structure, an issue that still needs to be addressed. Serological characterization revealed at least 18 different serotypes (A-R) with ORT of serotype A to be predominate among poultry. This study aimed to establish a multilocus sequence typing (MLST) scheme for ORT that could easily be used by other laboratories and allows for worldwide comparison of sequence data. For this purpose, 87 ORT strains from different poultry hosts, geographical origins, years of isolation and serotypes were included in the analysis to identify correlations. Fourteen different sequence types (ST) were found. The most common ST1 was identified in 40 ORT strains from turkeys and chickens on 4 continents and in 3 different European countries. Together with ST9, both STs represented over three quarters (77%) of ORT strains used in the MLST analysis and included strains of frequently cross-reacting ORT serotypes A, E and I. Nine STs were only represented by one ORT strain and might indicate possible avian host, disease or serotype-specific relationships. In contrast, discrepancies between serotype and phylogenetic relatedness were clearly demonstrated by ORT strains that belonged to identical serotypes but differed in their ST. The overall identified low genetic diversity among strains isolated from turkeys and chickens independent of host and geographical origins suggests that ORT has only recently been introduced into domestic poultry and dispersed worldwide.

[La] Idioma:eng
[Ab] Resumo:The objective of this study was to verify the hypothesis that increasing levels of dietary methionine can stimulate the mechanisms of cell-mediated and humoral immunity in young turkeys. The blood and organs involved in cell-mediated and humoral immune responses were analyzed in 8-week-old turkeys that had been vaccinated against Ornithobacterium rhinotraheale (ORT) infection (on days 17 and 48). The birds were fed diets with a low (LM), medium (MM) and high (HM) methionine content (0.45 and 0.40%, 0.60 and 0.51%, 0.71 and 0.57% in weeks 1 - 4 and 5 - 8, respectively). Dietary methionine supplementation led to a significant increase in body weights of turkeys at 56 days of age, from 3532 g in group LM to 3720 g in group MM and 3760 g in group HM (p=0.001). A significant increase in vaccine-induced antibody titers against ORT was noted in group HM relative to group LM (p=0.006). Increasing levels of methionine had no significant effect on total serum IgG nor IgM levels and most serum biochemical parameters, TP, ALB, GLOB, GLU, AST, ALP, P and Ca. In comparison with group LM, group HM turkeys were characterized by a lower percentage of IgM⁺ B cell subpopulation in the blood and bursa of Fabricius. The percentages of CD4⁺ and CD8⁺ T cell subpopulations in the bursa of Fabricius in group HM were significantly different from those found in groups LM and MM. The highest percentages of CD4⁺ T cells and CD8⁺ T cells in the spleen were observed in groups LM (p<0.001) and HM (p=0.04), respectively. The differences were statistically significant relative to the remaining groups. Turkeys of group LM were characterized by a lower CD4⁺ T cell percentage in the thymus (p<0.001) and a lower CD8⁺ T cell percentage in the cecal tonsils (CTs) (p<0.01). Vaccination against ORT resulted in a significant increase in the percentage of CD4⁺CD8⁺ T cell subpopulation and a decrease in the percentage of CD8⁺ T cell subset in the spleen.

[Ti] Título:Retrospective Study on the Isolation of Ornithobacterium rhinotracheale from Chickens and Turkeys in Central California: 294 cases (2000-12).

[Ab] Resumo:Ornithobacterium rhinotracheale is a rod-shaped, gram-negative, and mostly oxidase-positive bacterium that causes respiratory infections in chickens and turkeys worldwide and can also spread to nonrespiratory organs. The present report analyzes 294 cases in which O. rhinotracheale was isolated from turkeys or chickens in central California in the years 2000 through 2012. Two hundred sixteen cases were from turkey flocks and 78 from chicken flocks. The median age of turkey flocks was 8.7 wk; the median age of chicken flocks was 6.4 wk. From turkeys, O. rhinotracheale was more often isolated from August to January than during the rest of the year. Chickens cases were more evenly distributed throughout the year. The organs with the highest isolation rate were the infraorbital sinus and trachea, followed by lungs and air sacs. Isolation from other organs was rare. Pure cultures were obtained from relatively more turkey organs than chicken organs. The organ from which there was the highest chance to obtain a pure culture was the air sac. In 108 turkey flocks (50.0%) and 64 chicken flocks (82.1%) at least one other respiratory pathogen was detected. The most common gross lesions were increased mucus in trachea, caseous or fibrinous exudate in the air sacs, consolidated lungs indicating pneumonia, congested and edematous lungs, and a flattened trachea. For most types of lesions, the percentage of affected turkeys was higher than the percentage of affected chickens. The percentage of birds with lesions was higher if other respiratory pathogens were present. Overall, the host species (turkey or chicken) was a more important factor for the prevalence of most lesions than the detection of other respiratory pathogens. The most common histopathologic lesions in the sinus and trachea were heterophilic or mononuclear inflammatory cell infiltration. In the lungs and air sacs, the inflammation was characterized by heterophilic infiltration and/or fibrin accumulation. These results are helpful in selecting the most appropriate samples for isolation of O. rhinotracheale. In addition, they show the incidence of the bacterium in turkeys and chickens and which lesions can be expected after infection with O. rhinotracheale, and they indicate that in some cases O. rhinotracheale can be the primary, or at least the major, pathogen.

[Ti] Título:Pharmacokinetic and pharmacodynamic properties of gamithromycin in turkey poults with respect to Ornithobacterium rhinotracheale.

[Ab] Resumo:The macrolide gamithromycin (GAM) has the ability to accumulate in tissues of the respiratory tract. Consequently, GAM might be a suitable antibiotic to treat bacterial respiratory infections in poultry, such as Ornithobacterium rhinotracheale. As O. rhinotracheale infections are common in turkey flocks, the aim of this study was to determine the pharmacokinetic (PK) parameters of GAM in plasma, lung tissue, and pulmonary epithelial lining fluid (PELF) of turkeys and to correlate them with pharmacodynamic (PD) characteristics (PK/PD). The animal experiment was performed with 64 turkeys, which received either a subcutaneous (SC, n=32) or an oral (PO, n=32) bolus of 6 mg GAM/kg body weight (BW). GAM concentrations in plasma, lung tissue, and PELF were measured at different time points post administration (p.a.), and PK characteristics were determined using non-compartmental modeling. The maximum plasma concentration after PO administration was ten-fold lower than after SC injection (0.087 and 0.89 µg/mL, respectively), whereas there was no difference in lung concentrations between both routes of administration. However, lung concentrations at day 1 p.a. were significantly higher than plasma levels for both routes of administration (2.22 and 3.66 µg/g for PO and SC, respectively). Consequently, lung/plasma ratios were high, up to 50 and 80 after PO and SC administration, respectively. GAM could not be detected in PELF, although this might be attributed to the collection method of PELF in birds. The GAM minimum inhibitory concentration (MIC) was determined for 38 O. rhinotracheale strains; MIC50 and MIC90 were 2 and >32 µg/mL, respectively. PK/PD correlation for lung tissue demonstrated that the time above the MIC90 of the susceptible population (2 µg/mL) was 1 day after PO bolus and 3.5 days after SC administration. The area under the curve (AUClast)/MIC ratios for lung tissue after SC and PO administration were 233 and 90, respectively. To conclude, GAM is highly distributed to lung tissue in turkey poults, suggesting that it has the potential to be used to treat respiratory infections such as O. rhinotracheale.

[Ab] Resumo:Ornithobacterium rhinotracheale (ORT) is a Gram-negative bacillus that causes respiratory disease in birds, and directly affects the poultry industry. The mechanisms behind these infections are not completely known. Currently, its capacity to form biofilms on inert surfaces has been reported; however, the conditions for biofilm development have not been described yet. The present work was aimed at identifying the conditions that enhance in vitro biofilm formation and development by ORT. For this, serovars A-E were analysed to assess their ability to induce biofilm development on 96-well flat-bottom polystyrene microtitre plates under diverse conditions: temperature, incubation time, and CO2 concentration. The results obtained showed not only that all serovars have the ability to produce in vitro biofilms, but also that the optimal conditions for biofilm density were 40°C after 72 h at an elevated CO2 concentration. In conclusion, ORT biofilm formation depends on the environmental conditions and may contribute to the persistence of this microorganism.

[Ab] Resumo:Chlamydia psittaci is prevalent in broiler chicken production. However, the role of C. psittaci in the respiratory disease complex needs to be clarified. Our aim was to identify the time point when a C. psittaci infection appeared on a broiler farm and to examine the presence of other respiratory pathogens at that time. We focused on the 'major' respiratory pathogens occurring in Belgian broilers, namely infectious bronchitis virus (IBV), avian metapneumovirus (aMPV), Ornithobacterium rhinotracheale, Mycoplasma gallisepticum and Mycoplasma synoviae, and examined their co-occurrence with C. psittaci on three commercial broiler farms. For all farms, 1-day-old broilers showed high maternal antibody titres against C. psittaci in the presence of viable C. psittaci. Maternal antibodies seemed to protect against respiratory signs. Maternal antibodies declined and clinical outbreaks could be identified serologically even before maternal antibodies completely disappeared. Mixed infections with genotypes B/C and B/C/D were observed. Broilers with C. psittaci antibody increases showed conjunctivitis, signs of upper respiratory disease and dyspnoea. C. psittaci always preceded an O. rhinotracheale infection. Infections with aMPV, IBV or Mycoplasma spp. were not observed. Evidence was provided that C. psittaci could occur at an early age in broilers without a predisposing respiratory infection. Both C. psittaci and O. rhinotracheale should be considered when developing prevention strategies for respiratory disease in broilers.

[Ab] Resumo:High prevalence of leg disorders in fattening meat turkey farm was observed. Four birds as well as tracheal and joint swabs were submitted to the Bavarian Health and Food Safety Authority in Oberschleissheim and to the Institute of Poultry Diseases, Faculty of Veterinary Medicine, Free University of Berlin. At the post-mortem, all birds showed an inflammation of the hock joints (intertarsal joint). The histopatholical investigations revealed a chronic inflammation of the joint and amyloid deposits in the joints in two cases as well as in different tissues (liver, spleen and kidneys) in another two cases. Using polymerase chain reaction, Ornithobacterium rhinotracheale-DNA could be detected in the examined tracheal and joint swabs. On the other hand, Mycoplasma gallisepticum- and Mycoplasma synoviae-DNA could not be detected. A causal correlation between the detected infectious agent and amyloidosis in relation to the leg disorders were discussed.
