was diagnosed, and amoxicillin-clavulanate and prednisone were prescribed for 7 days.
Among different diagnosis codes at admission, the highest rate of positivity for influenza was recorded for myalgia and clinical suspicion of influenza (both above 80%), followed by other diagnoses of respiratory infections, such as acute rhinopharyngitis, tracheitis, laryngotracheitis
, or laryngopharyngitis (Fig.
Information about the data of the normal anatomical structures of living creatures is of importance in accurate evaluation of radiographic examinations, in understanding of the surgical procedure results (Weiglein et al., 1992), and in the diagnosis of diseases widespread among avian species such as avian influenza and laryngotracheitis
(Calnek et al., 1991).
The laying pullets imported from South Africa had already been vaccinated for FPV on day 1 with the commercial fowlpox-vectored infectious laryngotracheitis
vaccine and day 17 with the fowlpox-vectored infectious laryngotracheitis/avian encephalomyelitis vaccine.
Croup or laryngotracheitis
is common in children and rare in adults.
Different species of the virus lead to different diseases; for example, HCoV-OC43 leads to sore throats while HCoV-NL63 causes laryngotracheitis
and nonfatal respiratory tract infections in children and the elderly.
Naturally occurring dual infection of layer chickens with fowlpox virus and gallid herpesvirus 1 (infectious laryngotracheitis
virus) can be diagnosewith the help of electron microscopy, PCR andhistology (24).
Other respiratory complications were bronchitis 5(10%) and laryngotracheitis
Antibodies against MG and infectious laryngotracheitis
virus were found in 36.7% and 30% of the animals, respectively.
