Haemoproteus and Plasmodium species are widespread avian blood parasites. Several known for their high virulence have caused significant declines in naïve bird populations. The impact of closely related parasites is largely unknown. Recently we reported a lethal disease two parrot aviaries by Here show that the causative pathogen minutus responsible further 17 outbreaks Denmark, Germany Great Britain. All affected parrots endemic to Australasia South America. We sequenced cytochrome b gene...
Measuring the ratio of heterophils and lymphocytes (H/L) in response to different stressors is a standard tool for assessing long-term stress laying hens but detailed information on reliability measurements, measurement techniques methods, absolute cell counts often lacking. Laying offered sites nest boxes at ages were compared two-treatment crossover experiment provide procedure measuring difficulties interpretation H/L ratios commercial conditions. pen-specific depended age aviary system....
Birds of prey are found increasingly in captive situations. When sick, these animals show only very subtle signs disease, making the detection disease difficult. For this reason, analysis hematologic parameters is a useful technique for avian veterinarian. However, birds most frequently transported to veterinary clinic health check-up. This study investigates effects transport-related stress on heterophil and lymphocyte morphology peregrine falcons (Falco peregrinus) Harris's hawks...
Blood samples of 86 captive panther chameleons (Furcifer pardalis) were collected in January and August from the ventral coccygeal vein order to establish reference intervals clinical healthy individuals under similar husbandry conditions for plasma biochemistry hematology this species. Significant differences found phosphorus, glucose, total protein, albumin, white blood cell count between males females both seasons. Calcium, alanine aminotransferase, aspartate lactate dehydrogenase varied...
Abstract Background Species of Plasmodium (Haemosporida, Plasmodiidae) are remarkably diverse haemoparasites. Information on genetic diversity avian malaria pathogens has been accumulating rapidly, however exo-erythrocytic development these organisms remains insufficiently addressed. This is unfortunate because, contrary to species parasitizing mammals, the parasites undergo several cycles development, often resulting in damage various organs. Insufficient knowledge most described precludes...
Summary Objective: A disease is described in juvenile tortoises (Testudo graeca and Geochelone elegans) consisting mainly of a soft carapace, plastron deformed skeleton. The aim this study was to determine histopathological lesions the biological properties isolated viruses. Materials methods: Clinical signs gross pathology were determined on diseased healthy appearing tortoises. Paraffin sections stained with HE, PAS Prussian Blue histologically examined. Terrapene heart (TH-1) cell...
Monitoring and early detection of emerging infectious diseases in wild animals is crucial global importance, yet reliable ways to measure immune status responses are lacking for the wild. Here we assess usefulness bio-loggers detecting disease outbreaks free-living birds confirm detailed using leukocyte composition large-scale transcriptomics. We simulated natural infections by viral bacterial pathogens captive mallards (Anas platyrhynchos), an important vector avian influenza virus. show...
A 6-week-old, parent-reared peregrine falcon (Falco peregrinus) was presented with spastic hypertonus of its hind limbs unknown origin and duration. Radiologic examination revealed smooth periosteal reactions ventrally at thoracic vertebrae 5 to 7. Contrast-enhanced computed tomography identified the swelling as inflammation; antibiotic, antimycotic, anti-inflammatory, analgesic treatments were initiated, vitamins minerals supplemented. Because bird's condition did not improve after 10 days,...
The objective of the present study was to assess level stress imposed on Lohmann Silver laying hens kept in a small group housing system with elevated perches (Eurovent (EV) 625a-EU, sizes 40, 60 hens, four two different heights) compared furnished cages (Aviplus, 10, 20, 30 hens) and an aviary winter garden (Natura, pens, 1,250 under identical management feeding conditions. Each within compartments EV were either incorporated stepped position (ST, front back heightened) or only being (BE)....
An adult, wild-caught electric eel (Electrophorus electricus), weighing 18 kg and measuring 2 m in length, presented with bilateral swellings behind the pectoral fins, lethargy, anorexia for days. Anesthesia was performed immersion tricaine methanesulphonate supplemented 0.11 mg/kg medetomidine 2.2 ketamine intramuscularly. Endoscopy revealed blood oral gastric cavity. The stomach grossly enlarged, flaccid, contained a lead wire which removed manually. Blood values were severely elevated....
Einleitung Bisherige Studien zur Sarcocytis (S.) calchasi-induzierten Pigeon Protozoal Encephalitis (PPE) lieferten inkonstante Ergebnisse in Bezug auf läsionsassoziierte Erregernachweise und diesbezügliche tierartliche Unterschiede bei Zwischenwirten.
