Castellaniella: Are we missing this bacteria in lameness cases?

In the Fall 2023 issue of the Poultry Informed Professional newsletter from PDRC, there was an article describing isolation of Castellaniella from broiler breeders since 2018. They are initiating a research project to further investigate this bacteria that causes clinical signs of ‘tenosynovitis, femoral head necrosis, pericarditis and/or swollen wattles with submandibular edema’. When investigating broiler breeder lameness cases we can have difficulty obtaining good bacterial growth from obviously infected joints (good postmortem and histologic lesions) and it is unclear if this is due to previous treatment (no treatment history given). In discussion with Dr. Ðurđa Slavić (AHL bacteriologist), anaerobic culture must be ordered with aerobic culture to isolate this bacteria. Our routine is to order only aerobic culture due to cost and the number of samples we collect for lameness cases. In discussion with the other avian pathologists, if there has not been previous flock treatment for lameness, we would like to order anaerobic culture on at least 2 samples (i.e. joint swab) per case in order to determine if this organism is present. For postmortem cases of lameness, we will proceed with this approach starting February 1, 2024 unless veterinarians specifically indicate they are not interested in this testing. Please include flock treatment history when submitting lameness cases for postmortem examination. We will reevaluate the process as we go forward.


Fowl Adenovirus (FAdV, IBH), Infectious Bronchitis Virus (IBV), Infectious Bursal Disease Virus (IBDV) and Reovirus strains in Ontario (December 1, 2022 to Nov 30, 2023 – Q1 to Q4 2023).

Dr. Emily Martin and Dr. Davor Ojkic

In the OAHN year running from December 2022 to November 2023 the following tables show sequencing data from the AHL Virology lab for Ontario cases of FAdV, IBV, IBDV and reovirus. The most common field strains are highlighted in grey.


Poultry Veterinarian Survey Highlights – Q4 2023 (Sep-Nov)

Broilers

Early systemic bacterial infection (<14 d old) – ESBI

AHL: The number of cases were decreased from the previous 3 quarters. All cases had at least E. coli isolated either in pure culture or in combination with E. cecorum, or S. aureus.

Practitioners: Indicated as a commonly seen condition with stable to equally increased and decreased cases this quarter. Cases were attributed to Escherichia coli and Enterococcus cecorum.

Other causes of early mortality (>14 d old)

AHL: No other causes of early mortality were identified this quarter.

Practitioners: Stable this quarter with spiking mortality syndrome, heart attack and dehydration as main causes.

Late systemic bacterial infection (>14 d old) – LSBI

Practitioners: Reported stable numbers of infections with one respondent reporting decreased cases with E. coli, E. cecorum and P. aeruginosa listed as the main bacteria identified. Also, practitioners reported that between September and November 2023, 10-64 % of E. coli isolates were identified to be resistant to Trimethoprim sulfa (TMS).

Lameness – viral

AHL: The confirmed reovirus pathology cases were decreased from the previous 3 quarters but were increased from Q1 and Q3 2023. Fewer isolates were sequenced and from those that were sequenced the only strain identified was SK_R12. Reovirus suspicious cases (identified on histopathology) were increased from Q3 2023 but decreased from Q1 and Q2 2023.

Practitioners: Cases were reported as stable by practitioners with one veterinarian reporting decreased cases. The frequency of cases identified was mostly rare in the broiler flocks this quarter.

Lameness – bacterial
