In the present study, the influence of stress from handling and transport on some frequently examined blood parameters of racing pigeons was evaluated. After 3 hr, there was a highly significant (P < 0.01) increase in the number as well as in the percentage of heterophils and decrease of lymphocytes. In clinical chemistries, increases of creatine kinase and(More)
A longitudinal study was performed in order to investigate virus excretion and viraemia during a clinical outbreak of the psittacine beak and feather disease in budgerigars (Melopsittacus undulatus). Viral nucleic acid was detected in feathers, cloacal swabs and blood samples. Overall, beak and feather disease virus (BFDV) DNA was detected most commonly in(More)
Voriconazole, a highly potent triazole antifungal agent with high in vitro activity against a wide variety of fungal pathogens, appears to be an option for the treatment of aspergillosis in birds. To gain initial information on pharmacokinetics, bioavailability, and tissue distribution of voriconazole in birds, we evaluated voriconazole in chickens in a(More)
We established reference ranges for three hematologic and 15 clinical chemistry parameters of 40 clinically healthy birds of the genus Eos. The following species were included to the study: Eos histrio (n = 19), Eos squamata (n = 8), Eos bomea (n = 5), Eos reticulata (n = 4), Eos cyanogenia (n = 4). Detailed information concerning methodology, which is(More)
Many migrating birds undertake extraordinary long flights. How birds are able to perform such endurance flights of over 100-hour durations is still poorly understood. We examined energy expenditure and physiological changes in Northern Bald Ibis Geronticus eremite during natural flights using birds trained to follow an ultra-light aircraft. Because these(More)
The present study is the first to monitor plasma chemistries of a group of 30 Hermann's tortoises (HTs) over two summer seasons to characterize and quantify seasonal and gender-related influences. The following analytes were analyzed: ALT, ALP, AST, BA, CA, CHO, CK, LDH, GLU, GLDH, P, TP, TRIG, urea and uric acid. Two-way repeated-measures ANOVA, mean(More)
The aim of the study was to obtain basic data on individual biological variation, the required number of specimens to define the homeostatic setpoint (the aspired value of a variable adjusted to the individuals homeostasis) and critical differences of selected chemistry parameters in budgerigars (Melopsittacus undulatus). Blood from 99 healthy budgerigars(More)
The diagnostic evaluation of the glomerular filtration rate by urinary clearance has significant practical limitations in birds because urine is excreted together with feces. Thus, pharmacokinetic modeling of an exogenous plasma creatinine clearance could be useful for assessing renal creatinine excretion in birds. For this study, creatinine (50 mg/kg) was(More)
Five mute swans (Cygnus olor) were presented with inability to stand or with abnormal positioning of a leg. Clinical examinations indicated the possibility of femoral fractures or coxofemoral luxations. The suspected diagnosis was proven by means of computed tomography (CT), while superimposition of gastrointestinal contents or other artefacts limited(More)
The aim of the study was to investigate if there is a clinically relevant influence of daytime or season and if there are sex-dependant differences in some frequently determined clinical chemistry parameters. The study was performed with 99 1.5- to 2-year old healthy budgerigars of three races. A harmonic regression analysis was performed taking into(More)
