The effect of the dietary inclusion of clinoptilolite on the haematological parameters of dairy cows has not been studied yet; however in mice, prolonged zeolite administration causes disturbances in the adaptation of erythropoiesis in periods of increased demands. The aim of the present study was to investigate whether the long term supplementation of two levels (1.25 and 2.5%) of clinoptilolite in the concentrate feed of dairy cows has any effect on their haematological parameters. Fifty-two clinically healthy Holsteincows were randomly assigned to one of three groups according to their age and parity. The first group (group A, n = 17) was...

We studied the ultrastructure of the epithelium of terminal bronchioles in rabbits exposed for 96 hours to hypoxia (10% O2) in isobaric hypoxic chamber. Rabbits of the first control group (treated controls) were exposed for the same time in the same hypoxic chamber with atmosphere regulated at 21% O2. In both groups, the temperature in the chamber was 23°C and humidity 100% during the whole experiment. The second control group (untreated controls) was kept under standard conditions. The target cells for the effect of high temperature, humidity and normobaric hypoxia were the secretory elements. Both in hypoxic animals and treated...

In this study, C. perfringens strains isolated from healthy and diseased sheep were analysed by multiplex PCR in order to to detect the presence of the alpha, beta, epsilon, iota and enterotoxin genes. C. perfringens was isolated from 52 of 104 sheep with enterotoxemia signs and from 61 of 194 clinically healthy sheep. Genotyping of 52 strains from diseased sheep indicated that 33 (64%) were type A, 11 (21%) type D and 8 (15%) type C. Of 61 strains from healthy sheep, 58 (95%) were type A and 3 (5%) type D. The other types of C. perfringens were not detected, and none of the isolates contained the enterotoxin gene. This result...

An episode of mortality in waterbirds occurred on a sedimentation reservoir with effluents from the sugar beet processing plant at Hrusovany n.J. (South Moravia, Czech Republic) in summer 2003: tens of black-headed gulls (Larus ridibundus), several lapwings (Vanellus vanellus), one little ringed plover (Charadrius dubius), one ruff (Philomachus pugnax), one wood sandpiper (Tringa glareola), and two avocets (Recurvirostra avosetta) died. One of the two avocets and the plover, local breeders, were examined and found positive for Clostridium botulinum type C toxin by use of the toxin-neutralization...

Avian tuberculosis was diagnosed histopathologically and microbiologically in two pheasants (Phasianus colchicus) and two peafowl (Pavo cristatus) kept in the same aviary. The incidence of avian tuberculosis in the aviary was 6%. Non-mineralized caseogranulomas were present in the liver (3 cases), spleen (3 cases), intestine (2 cases), lung (2 cases), and cloaca (1 case). Granulomas in the lung were present only in peafowl. The presence of granulomas in the lung of both infected peafowl suggests that peafowl were exposed to the agent via the respiratory route rather than the alimentary route. Histopathologic findings were typical...
Financial impact of foot-and-mouth disease inTurkey: acquisition of required data viaDelphiexpert opinion survey

The main obstacle in assessing the financial impact of foot-and-mouth disease inTurkeyis unavailability of reliable data. Considering this issue, this study aimed at using a Delphi Expert Opinion Survey (DEOS) method to obtain data required for economic analysis of FMD inTurkey. This study concluded that although there were problems in obtaining some information from the experts, in general theDelphitechnique is a promising way of obtaining animal health data, which is otherwise missing and/or not regularly recorded in developing countries.
