Mortality In Some Domesticated Pigeons (Columba Livia) From Jammu, India, Syed Mehmood, Nawab Nashiruddullah, Jafrin Ara Ahmed

Turkish Journal of Veterinary & Animal Sciences

Although pigeons are reared for recreational purposes in Jammu region, disease occurrence is sparsely documented. Based on clinical signs, lesions and laboratory investigation, approximately 600 out of 4000 (15%) domestic pigeons were found to be disease affected. Necropsy of 60 birds was conducted to determine the cause of death. Haemoproteus columbae demonstrated within erythrocytes and various development stages in tissue and endothelial schizogony caused majority deaths due to pneumonia and hepatitis (45%) accompanied by severe vascular and tissue reaction. Newcastle disease (20%) confirmed by positive serum haemagglutination inhibition manifested in a severe neurological form with characteristic cerebral malacia and demyelination. …

A Review Of Avian Influenza A Virus Associations In Synanthropic Birds, Susan A. Shriner, J. Jeffrey Root

USDA Wildlife Services: Staff Publications

Avian influenza A viruses (IAV) have received significant attention due to the threat they pose to human, livestock, and wildlife health. In this review, we focus on what is known about IAV dynamics in less common avian species that may play a role in trafficking IAVs to poultry operations. Specifically, we focus on synanthropic bird species. Synanthropic species, otherwise known as peridomestic, are species that are ecologically associated with humans and anthropogenically modified landscapes, such as agricultural and urban areas. Aquatic birds such as waterfowl and shorebirds are the species most commonly associated with avian IAVs, and are generally considered …

Limited Transmission Of Emergent H7n9 Influenza A Virus In A Simulated Live Animal Market: Do Chickens Pose The Principal Transmission Threat?, Angela Bosco-Lauth, Richard A. Bowen, J. Jeffrey Root

USDA Wildlife Services: Staff Publications

Emergent H7N9 influenza A virus has caused multiple public health and financial hardships. While some epidemiological studies have recognized infected chickens as an important bridge for human infections, the generality of this observation, the minimum infectious dose, and the shedding potential of chickens have received conflicting results. We experimentally tested the ability of domestic chickens (Gallus gallus domesticus) to transmit H7N9 to co-housed chickens and to several other animal species in an experimental live animal market. Results indicated that an infected chicken failed to initiate viral shedding of H7N9 to naIve co-housed chickens. The infected chicken did, however, …

Spatial Memory In Pigeons On A Four-Arm Radial Maze, Robert H.I. Dale

Robert H. I. Dale

Pigeon spatial memory was examined using a four-arm radial maze. The maze had four arms, spaced at 90° intervals, extending radially from a central choice area. Subjects were forced into three arms, then permitted two choices to enter the remaining ann. Five subjects chose accurately (90% correct) with delays of 5 min or less, their choices depended on extramaze cues, and the food in the target arm provided no essential cues. After an incorrect first choice, subjects' second choices were more accurate than chance. These data suggest that, while spatial memory has many similar characteristics in rats and pigeons, pigeon …

High Clinical Disturbance And Mortality In Pigeon Flocks Caused By Hadjelia Truncata Infection In Sistan, Iran, Reza Nabavi, Javad Khedri, Mehdi Jahantigh

Turkish Journal of Veterinary & Animal Sciences

A large number of birds in 3 pigeon flocks (containing 637 individuals) were severely affected by Hadjelia truncata. This was observed in April 2011 in Sistan District in Iran. In the affected birds, progressive weight loss, weakness, and death were observed. In the necropsy of 8 cases the gizzards were larger and softer than normal and in all of them distortion was detected. Stool examination by the Clayton Lane method revealed 72% infection among domestic pigeons. The hematological analysis of affected birds showed signs of decline in hematocrit and total protein volume. A levamisole treatment program could successfully remove the …

The Long Life Of Birds: The Rat-Pigeon Comparison Revisited, William A. Buttemer, Anthony J. Hulbert, M K. Montgomery

Faculty of Science - Papers (Archive)

The most studied comparison of aging and maximum lifespan potential (MLSP) among endotherms involves the 7-fold longevity difference between rats (MLSP 5y) and pigeons (MLSP 35y). A widely accepted theory explaining MLSP differences between species is the oxidative stress theory, which purports that reactive oxygen species (ROS) produced during mitochondrial respiration damage bio-molecules and eventually lead to the breakdown of regulatory systems and consequent death. Previous rat-pigeon studies compared only aspects of the oxidative stress theory and most concluded that the lower mitochondrial superoxide production of pigeons compared to rats was responsible for their much greater longevity. This conclusion is …

Effects Of Medetomidine-Ketamine Combination Anaesthesia On Electrocardiographic Findings, Body Temperature, And Heart And Respiratory Rates In Domestic Pigeons, Metehan Uzun, Sedat Yildiz, Gülteki̇n Atalan, Mehmet Kaya, Nesri̇n Sulu

Turkish Journal of Veterinary & Animal Sciences

The applications of medetomidine (M) as a pre-anaesthetic and ketamine (K) as an anaesthetic agent were investigated in seven domestic pigeons in terms of the degree of anaesthesia (DA) and alterations in physiological parameters. An intramuscular (IM) injection of M (200 µg/kg) was followed by administration of K (120 mg/kg, IM) after 10 min. Body temperature (BT), respiratory rate (RR), heart rate (HR), DA, and electrocardiogram (ECG) findings were determined before (0 min) and 10 min after the application of M, and 5, 15, 30, 45 and 60 min after the administration of K. All pigeons had 4^{th} degree anaesthesia …

Blood Parasites Of Wild Pigeons In Ankara District, Yunus Gicik, M. Özkan Arslan

Turkish Journal of Veterinary & Animal Sciences

A total of 200 wild pigeons, 82 young and 118 adults, captured from 12 localities in Ankara District, were examined for blood parasites. Haemoproteus columbae was found in 57% (114/200) of the pigeons examined, and no other blood parasites were detected.

Morphology Of The Spinal Cord In The Chicken, Duck And Pigeon, R. Meri̇h Haziroğlu, İ. Önder Orhan, Di̇nçer Yildiz, M. Erdem Gülti̇ken

Turkish Journal of Veterinary & Animal Sciences

The morphology of the spinal cord in 15 chickens, 15 ducks and 15 pigeons obtained from the Ankara region were examined. The spinal cord consisted of 15 cervical, 7 thoracic, 14 lumbosacral and 5 coccygeal segments (a total of 41 segments) in the chickens; 15 cervical, 8 thoracic, 16 lumbosacral and 5 coccygeal segments (a total of 44 segments) in the ducks and 13 cervical, 6 thoracic, 13 lumbosacral and 5 coccygeal segments (a total of 37 segments) in the pigeons. The cervical enlargement was composed of cervical segments 13-15 and thoracic segments 1-2 in the chickens; cervical segments 12-15 …

Scanning Electron Microscopy Of The Lateral Ventricle Of The Pigeon Brain, P. Mestres, K. Rascher, J. D. Delius

Scanning Electron Microscopy

Adult pigeons of both sexes were used for this study. Depending upon the distribution of various surface profiles, for example cilia, microvilli and blebs, ependymal areas with differing surface patterns were distinguished in the lateral ventricle. The topographical locations of these areas with respect to the underlying forebrain nuclei were determined in accord with the atlas of Karten and Hodos (1967). The medial surface (A) of the ventricle was much more densely ciliated than the lateral surface (B). There did not appear to be any correlation between a given surface pattern and a specific type of underlying nervous tissue. Comparison …
