Safety of an Intravenous Formulation of Voriconazole as an Intramuscular Injection in Pigeons ( f. ).

Aspergillosis is a common disease in birds. Currently, avian aspergillosis is treated with voriconazole administered orally, although intramuscular (IM) administration increases bioavailability and is more effective in treating generalized aspergillosis. The objective of this study was to evaluate the safety of the intravenous formulation of voriconazole as an IM injection in the pectoral muscles of pigeons ( f.

Reference intervals for Cu, Mg, and Zn in captive gyrfalcons and other falcon species in the United Arab Emirates.

Falconry is a long-standing tradition in the United Arab Emirates (UAE), and in 2016, falconry was included by UNESCO in the list of intangible cultural heritage of humanity. The health and wellness of falconry raptors is a priority for the local culture; plasma chemistry analysis plays an important role in monitoring, assessing, and managing diseases in avian patients. Imbalances of Cu, Mg, and Zn have been linked to several diseases in avian species; therefore, determining the reference intervals (RIs) of these minerals has important implications in the clinical management of falcons.

Disposition of posaconazole after single oral administration in large falcons (Falco spp): Effect of meal and dosage and a non-compartmental model to predict effective dosage.

Unlabelled: Posaconazole has been used anecdotally to treat aspergillosis in falcons resistant to voriconazole. In human medicine, it is used prophylactically in immunosuppressed human subjects with invasive pulmonary aspergillosis. So far, no studies have been performed in birds.

Multicentric Septic Osteomyelitis and Arthritis Caused by in a Gyrfalcon ().

An adult female gyrfalcon () was presented with a right-wing droop and weight loss. Radiographic images revealed osteolysis and osseous proliferation of the right shoulder and the mobile vertebra between the notarium and synsacrum. The tentative diagnosis was vertebral osteomyelitis secondary to septic arthritis.

Pharmacokinetics of voriconazole after a single intramuscular injection in large falcons (Falco spp.).

Voriconazole is one of the main azoles used to treat invasive aspergillosis in falconry raptors and birds. Despite the fact that there are studies for oral and intravenous use of voriconazole in birds, there are none for its effect after intramuscular use. Empirical use of intramuscular voriconazole in falcons, indicated quicker therapy response than the oral one.

First detection of Cryptosporidium parvum in falcons (Falconiformes): Diagnosis, molecular sequencing, therapeutic trial and epidemiological assessment of a possible emerging disease in captive falcons.

Cryptosporidiosis in raptors and falcons is well-known to be caused by Cryptosporidium baileyi and associated mainly with respiratory pathology. This report presents the diagnosis of an atypical cryptosporidiosis event caused by Cryptosporidium parvum, that to the authors' knowledge, is a case observed for the first time in falcons. Two falcons (Gyrfalcon x Peregrine hybrids) were presented for annual check without any clinical signs.

Serum protein electrophoresis by using high-resolution agarose gel in clinically healthy and Aspergillus species-infected falcons.

Serum protein electrophoresis has gained importance in avian medicine during the past decade. Interpretation of electrophoretic patterns should be based on species-specific reference intervals and the electrophoresis gel system. In this study, serum protein electrophoresis by using high-resolution agarose gels was performed on blood samples collected from 105 falcons, including peregrine falcons (Falco peregrinus), gyrfalcons (Falco rusticolus), saker falcons (Falco cherrug), red-naped shaheens (Falco pelegrinoides babylonicus), and hybrid falcons, that were submitted to the Dubai Falcon Hospital (Dubai, United Arab Emirates) between 2003 and 2006.

An outbreak of cryptosporidiosis in a collection of Stone curlews (Burhinus oedicnemus) in Dubai.

We describe an outbreak of cryptosporidiosis in Stone curlews kept in a mixed-species rearing unit in Dubai. Cryptosporidium was the predominant intestinal pathogen detected, although microbiological investigations revealed a concurrent Salmonella infantis infection in two of the 29 Stone curlew chicks that died. Nineteen of 29 birds had catarrhal enteritis associated with histopathological findings of numerous Cryptosporidium developmental stages at the mucosal surface.

Developmental intestinal aerobic microflora in the kori bustard (Ardeotis kori).

A study was carried out to investigate the normal aerobic bacterial flora of developing kori bustard (Ardeotis kori) chicks, captive bred at the National Avian Research Center, Abu Dhabi, United Arab Emirates. Faecal samples were collected from 14 birds at different ages from the first day of hatching until 99 days old and were cultured for aerobic bacteria. Several bacterial species were isolated from the cultures, they included Escherichia coli, Streptococcus viridians, Enterococcus faecalis, Klebsiella oxytoca, Proteus spp.

The use of voriconazole for the treatment of aspergillosis in falcons (Falco species).

To evaluate the clinical efficacy and safety of voriconazole for the treatment of aspergillosis in falcons, 20 falcons with aspergillosis admitted to the Dubai Falcon Hospital from August 2003 to May 2006 were treated with voriconazole. These falcons included 6 gyrfalcons (Falco rusticolus), 10 gyrfalcon hybrids, 1 lanner (Falco biarmicus), 1 saker (Falco cherrug), and 2 peregrine falcons (Falco peregrinus). Clinical signs were weight loss, inappetence, dyspnea, inspiratory stridor, tachypnea, and biliverdinuria.

Urinalysis as a noninvasive health screening procedure in Falconidae.

Clinical signs of renal disorders in animals, including raptors, are not specific. Furthermore, serum or plasma biochemical parameters change only when 70% of kidney function is lost. In this study, reference values of urine variables were established in clinically healthy falcons.

Susceptibility of fungi isolated from the respiratory tract of falcons to amphotericin B, itraconazole and voriconazole.

The minimum inhibitory concentrations (mics) of fungi isolated from the air sacs of falcons before (group 1), and during antifungal treatment with amphotericin B nebulisation and oral itraconazole or voriconazole (group 2), or with itraconazole alone (group 3) or voriconazole alone (group 4) were determined. Before treatment, 95 per cent of the isolates, including Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger and Aspergillus terreus, were susceptible to voriconazole at mics up to 0.38 microg/ml, and all the isolates were susceptible at mics up to 1 microg/ml.

An outbreak of low pathogenic avian influenza in a mixed-species aviculture unit in Dubai in 2005.

This case describes an outbreak of low pathogenic hemagglutinin 9 neuraminidase 2 avian influenza virus (AIV) in two white-bellied bustards (Eupodotis senegalensis), one stone curlew (Burhinus oedicnemius), and a blacksmith plover (Antibyx armatus) in a private zoologic collection in Dubai, United Arab Emirates. The four birds showed signs of respiratory disease, and all died as a result of disease or euthanasia. Attention has been paid to the diagnostic process and common differential diagnosis for upper respiratory tract disease in bustards, curlews, and plovers.

Assessment of a commercial sandwich ELISA in the diagnosis of aspergillosis in falcons.

A commercial sandwich elisa (Platelia Aspergillus EIA; Bio-Rad) developed for the detection of galactomannan, a major cell wall constituent of Aspergillus species, was tested for its efficacy in the diagnosis of aspergillosis in falcons. Ninety serum samples from 50 aspergillosis-positive falcons and 182 samples from 142 aspergillosis-negative falcons were tested. The sensitivity of the test was only 12 per cent and its specificity was 95 percent.

Medical dilemmas associated with rehabilitating confiscated houbara bustards (Chlamydotis undulata macqueenii) after avian pox and paramyxovirus type 1 infection.

Projects to rehabilitate confiscated animals must carefully consider the risks of disease when determining whether to release these animals back into the wild or to incorporate them into captive breeding programs. Avipox and paramyxovirus type 1 (PMV-1) infections are important causes of morbidity and mortality during rehabilitation of confiscated houbara bustards (Chlamydotis undulata macqueenii). This paper presents key findings of an intensive health monitoring program (physical condition, hematology, serology, endoscopy, microbiology, and virology) of two flocks of houbara bustards that survived outbreaks of septicemic avipox and PMV-1 respectively.

Plasma concentrations of vitamin E in six species of bustard (Gruiformes: Otididae).

Vitamin E (measured as alpha-tocopherol) and cholesterol concentrations were determined in plasma samples collected from 86 clinically healthy captive adult bustards of six species and 23 captive juveniles (6-12 mo old) of two of these species. Adult houbara bustards (Chlamydotis undulata macqueenii) had higher plasma alpha-tocopherol concentrations than juveniles (adult: mean +/- SE, 11.07 +/- 0.

Bacterial flora of the conjunctiva and nasal cavity in normal and diseased captive bustards.

A survey was carried out to describe the normal aerobic bacterial flora of the conjunctiva and nasal cavity of captive houbara bustards (Chlamydotis undulata), kori bustards (Ardeotis kori), and white-bellied bustards (Eupodotis senegalensis) maintained at the National Avian Research Center, Abu Dhabi, United Arab Emirates. A total of 58 samples were examined from the nasal cavity and 55 samples from the conjunctiva of healthy bustards. There was no bacterial growth in 45% of conjunctival samples.

Pseudomonas aeruginosa infections in kori bustards (Ardeotis kori).

Pseudomonas aeruginosa associated upper respiratory tract infections occurred in a flock of 19 juvenile kori bustards. Morbidity was 32% and all birds recovered after parenteral treatment with combinations of enrofloxacin, gentamicin and piperacillin, although gentamicin toxicity was suspected in one bird. A marked haemoresponse occurred 3-10 days after the onset of clinical signs and included leukocytosis, heterophilia, monocytosis and thrombocytosis.
