Rágcsálók és nyúlfélék emésztőszervi megbetegedései A csíkosmókus burunduk állatorvosi ellátása Több mint százhúsz esztendővel ezelőtt történt, hogy Ali — Állatkertünk legelső elefántja — megbetegedett.

Egészen pontosan az agyara kezdett fájni. Giardia and coccidia in humans nyilván nemcsak a serdülő afrikai elefántbikának jelentett gondot, hanem az állatkerti szakszemélyzetnek is. Végül harminc emberre volt szükség, hogy láncokkal és kötelekkel gúzsba kössék az állatot, és ezután került elő a fűrész!

Sajnos azt nem tudjuk biztosan, hogy a fájós agyar ellátása mennyire volt sikeres, mert a korabeli adatok e tekintetben ellentmondásosak.

Abban viszont biztosak lehetünk, hogy a beavatkozást senki emberfia nem nevezte egyszerűnek. Habár az ilyen típusú beavatkozásokat ma már megannyi eszköz könnyíti meg, az állatkerti állatorvosok munkája ma sem egyszerű feladat. Főképp akkor nem, ha a gazdasági haszonállatok vagy a kedvtelésből giardia and coccidia in humans háziállatok gyógyászatával hasonlítjuk össze ezt a munkát. A feladat ott sem könnyű persze, de giardia and coccidia in humans behatárolt azon állatok köre, amelyekkel foglalkozni kell.

Ha valaki, az állatorvos mindenképpen megtapasztalja, hogy az állatkertek az élővilág sokféleségének milyen széles keresztmetszetével foglalkoznak. Ez persze azt is jelenti, hogy nagyon nehéz a specifikus tapasztalatok felhalmozása. Hiszen az állatkerti állatorvos munkája során nem egy-két állatfaj nagy esetszámával találkozik, hanem nagyon sok fajjal, ám fajonként kicsi esetszámmal. Ilyen körülmények között még nagyobb szerepe van a tapasztalatcserének, annak, hogy az állatkerti állatorvosok megosszák egymással a tapasztalataikat.

Úgy gondolom, a hazai állatkerti szakma büszke lehet arra, hogy az állatkerti, illetve vadállatokkal foglalkozó állatorvosok Magyarországon évek óta ilyen remekül együtt tudnak működni. Biztos vagyok abban, hogy az idei találkozó előadásai, illetve az itt olvasható összefoglalók is segítenek abban, hogy a Magyarországon tevékenykedő, vadállatokkal, állatkerti jószágokkal foglalkozó állatorvosok még többet tanuljanak egymástól, és még eredményesebben segítsék munkájukkal azokat a célokat, amelyek minden állatkerti szakember közös ügyének számítanak.

Budapest, One would assume that within our profession the possibilities and limitations of telemetry applications giardia and coccidia in humans well recognized. However, the authors are confronted with inquires on a weekly basis that clearly demonstrate that in many cases fundamental knowledge is lacking. On the one hand the possibilities are hugely over-estimated and on the other, the potential is not fully exploited. From the onset it is essential to understand that telemetry is only a tool.

The questions to be answered in a project determine the type and specifications of the telemetry equipment and not the other way round. Before trying to select the appropriate telemetric method the following needs must be determined: 1.

These 3 factors will for the most part determine the weight giardia and coccidia in humans the unit.

Giardia and coccidia in humans weight of the unit must be seen in relation to the weight of the animal onto which it will be applied. Depending on the species-specific behaviour and other factors this weight can be increased in some or needs to be decreased in other species.

Before placing a telemetry device on an animal it is important to consider the applicable legislative constraints such as animal welfare, animal experimentation and radio transmission laws. Fixation There are numerous possibilities to affix a telemetric device on an animal.

The classic approach is to place the device externally on the animal, either with a collar mammals; Fig. Additionally, it is possible to place the unit sub-cutaneously or into the abdominal or coelomic cavity. This approach is particularly useful in species that giardia and coccidia in humans not tolerate a collar or that have a neck larger than the head.

It is important to note, that whereas in North America it is acceptable to combine an internal unit with an external antenna this practice is for helminthiasis kockázati tényezők most part not acceptable in Europe due to stricter animal welfare legislation.

In the past recovering units was difficult and most often than not, necessitated the re-capture or death of the individual. These have replaced the previous very unreliable releases based on the environmental degradation of rubber or cotton.

Using a small black powder explosion e. This technology also allows for the placement of units on juvenile animals that are still significantly growing in size e. Collar system on a mammal and backpack system on a bird 7 Fig. Pre-programmed drop-off that released the collar 19 months after deployment. VHF systems A large number of technological solutions are available to fulfil wildlife telemetry needs.

The simplest system is the radio-transmitter in the 2-metre bandwidth VHF. Using a so-called Hantenna it is possible to determine locations using triangulations.


This simple system however can easily be modified to collect additional data from the animal. Additionally, the individual pulse length can also be modulated allowing giardia and coccidia in humans supplementary information to be transmitted. To examine real time energetics and flight biology of free-ranging Eurasian Griffons Gyps fulvus in an alpine environment, a multi channel repeater telemetry system was used to measure heart giardia and coccidia in humans, body and ambient temperatures, and air pressure altitude.

It fulfilled the requirements for long-range transmission several km and long-term application years. The unit consisted of two distinct parts: an extracorporeal backpack and a smaller intra-abdominal implant.

We also used a similar system for chamois Rupicapra rupicapra Bögel et al. While simple systems are available commercially e. With the exception of complex and expensive Doppler-based systems the major disadvantage giardia and coccidia in humans VHF transmission is the low spatial resolution and the substantial manual labour effort necessary to acquire locational data.

GPS-store-on-board systems Due to the development and propagation of the Global Positioning System GPS satellite system it is very simple today to obtain locational data with an extremely high spatial resolution metres and and in dense forests the reception of the GPS signal can be problematic Dussault et al.

It is important to realise that the most significant constraint in units using GPS modules is data transmission from the affixed unit to the researcher. The data is downloaded from the unit after it is recovered using a drop-off or the re-capture of the animal. When using a pre-programmed drop-off it is important to plan a unit recovery strategy. This system is cheap and light, but has several noteworthy disadvantages: slow data transmission rate, low transmission range on the ground several metres which often necessitates aerial surveys and is problematic when the animal is moving.

If one plans to use a UHF transmission it is essential to give the behaviour of the examined species considerable thought — transmission should be programmed to coincide with the resting phases of the animal and the activity phases of the researcher!

This only applies if the animal does not rest in e. In areas with cell phone coverage this method provides a simple and reliable mode of data acquisition.

Presently we are using this type of system to track griffon vultures www. If the animal is outside GSM coverage the data is saved and automatically transmitted when it next regains a GSM cell.

All data is permanently stored in the unit and can be downloaded manually should the unit be retrieved. This system originally developed for oceanographic research is common in wildlife telemetry applications www.

Unfortunately the ARGOS system has performed poorly or not at all during the past years in central Asia and Europe due to undefined giardia and coccidia in humans interfering radio frequency rf noise Woodward pers.

Taking these facts into consideration it is essential that this type of collar is 9 thoroughly tested in the region of deployment on an animal of the same size as the study animal. While on the animal the signal strength is reduced and the pattern of RF radiation is altered. Though the spatial resolution is from - 1,m, it may for many applications, be sufficient. This could for example, be the case in long-range migration studies in some bird species.

Due to the problems with the ARGOS system described above novel approaches to data transmissions are being developed.


The very first models are being deployed and experience is generally lacking. Conclusions It would appear that telemetry solutions based on satellite transmissions are expensive. However, when considering the quality and quantity of data collected and subtracting the cost of the human resources and infrastructure necessary to collect similar data in the field, the costs are more than reasonable.

In contrast to a field researcher the satellite based collars function continuously on a 24 hours cycle which allows for an even spread of data collection. Giardia and coccidia in humans griffon vulture implanted with a multi channel repeater telemetry system as described above generates 1.

We therefore strongly recommend integrating post-collection data management in the project planning phase. Before deciding to use a unit with a very high spatial resolution it appears prudent to ensure access to digital maps and layers of the same resolution. It is pointless to collect data at 5 metres resolution, when in the evaluation phase the highest resolution is provided by a Finally, prior to implementing telemetry in a project it is important to study the recent literature and the specialised sites on the web for the most up to date literature and technical information.

Communicating with researchers that already use the selected product seems prudent. If carefully planed, adequate systems, respecting animal welfare considerations, can be found for most wildlife applications.
