Recurrent airway obstruction in horses - an allergic inflammation: a review
G. Moran, H. Folch
Vet Med - Czech, 2011, 56(1):1-13 | DOI: 10.17221/1566-VETMED 
Recurrent airway obstruction (RAO), also known as heaves, is a debilitating and incurable disease of the equine airway. Affected horses develop bronchoconstriction and neutrophilic airway inflammation as a result of exposure to specific airborne irritants and allergens such as hay mould and barn dust. Clinical signs of RAO include exercise intolerance, coughing, nostril flare and abdominal push related to respiratory effort. Evidence suggests that both the innate and acquired immune response contribute to the activation of inflammatory cells resulting in type I hypersensitivity and type III hypersensitivity reactions with an increased expression of...
Tomenendalova J: How to approach the QT interval in dogs - the state of the heart: a review
C.F. Agudelo, P. Scheer, J. Tomenendalova

The QT interval has been the objective of exhaustive attention in the past and also in recent times. A number of conditions, congenital and acquired, can have a direct effect on cardiac repolarization. Also drug regulatory agencies have showed increasing interest in the topic because certain drugs can prolong the QT interval to a level that produces ventricular arrhythmias. The dog is a species that shares some similarities with the human electrical system and has been used in human and veterinary research. We here present the current recommendations for QT measurement in dogs for use in clinical and experimental practice.

Bacillus anthracis can infect both livestock and humans. The importance of the treatment of the disease in humans has been underscored by the bioterrorism events of 2001 in the United States. The presence of PA and B/C genes (pX01 and pX02 plasmids) as well as susceptibility to several antimicrobial substances was determined in 11 strains of Bacillus anthracis isolated during two recent epizooties of anthrax which occurred in Croatia in 2002 among sheep and in 2006/2007 in cattle. The pX01 plasmid was observed in all of the examined strains, including vaccinal Sterne strains. However, the pX02 plasmid was...

Bovine respiratory disease caused by Mycoplasma bovis is a major health problem of cattle worldwide. It inflicts considerable financial losses on beef herds and is the most common cause of mortality in dairy cattle. Bacteriological examination of 35 nasal cavity samples from calves younger than three months of age identified Mycoplasma bovis in eight (22.9%) samples. These cattle were followed until 17 months of age, and repeated examination of nasal cavity samples before necropsy identified Mycoplasma bovis in four (11.4%) samples. At necropsy and lung samples for bacteriological and histological examination were collected. To identify...
Altered Na+/K+-ATPase expression plays a role in rumen epithelium adaptation in sheep fed hay ad libitum or a mixed hay/concentrate diet

Vet Med - Czech, 2011, 56(1):36-48 | DOI: 10.17221/1571-VETMED
In this study we investigated rumen papillae morphology and the localization and expression of theNa+/K+-ATPase in eight sheep fed hay ad libitum (h) or hay ad libitum plus additional concentrate (h/c). Four sheep were provided with the ad libitum h-diet for the complete three-week experimental period. The second group of four sheep received the h-diet for only one week and was fed the mixed hay/concentrate (h/c) diet for another two weeks. The amount of concentrate supplement was stepwise increased from 150 to 1000 g/day and given in two meals. Following slaughter rumen papillae from the atrium ruminis (AR),...
Light microscopic and immunohistochemical study of the trachea of the broad-snouted caiman (Caiman latirostris)
C.M. Santos, M. Abidu-Figueiredo, M.J. Teixeira, A.A. Nascimento, A. Sales
Vet Med - Czech, 2011, 56(1):49-54 | DOI: 10.17221/1568-VETMED
The purpose of this study was to examine the tracheal structure of the crocodile Caiman latirostris using light microscopy, histochemical and immunocytochemical techniques. The tracheal epithelium of C. latirostris consists of a ciliated pseudostratified columnar epithelium with goblet cells. The respiratory epithelium also includes endocrine cells immunoreactive to serotonin. The histochemical techniques demonstrated the presence of neutral and sulphated mucins secreted by goblet cells. The lamina propria consists of connective tissue with many reticular fibres. The elastic fibres are interspersed among collagen bundles, forming...
A one-foetus pregnancy monitored by ultrasonography and progesterone blood levels in a German Shepherd bitch: a case report
A. Domoslawska, A. Jurczak, T. Janowski
Vet Med - Czech, 2011, 56(1):55-57 | DOI: 10.17221/1567-VETMED
This case study describes the pregnancy of a German Shepherd bitch with a singleton (one puppy) litter as a result of early embryo resorption. Resorption was confirmed by ultrasonography and the pregnancy was regularly monitored by USG and measurements of progesterone levels until parturition. These levels stayed within the physiological range. One healthy puppy was delivered within the timeframe of a physiological pregnancy although the inner chorionic cavity diameter (ICCD) protocol used for predicting the time of parturition showed divergence from the real time of whelping.
