为了探讨驯鹿鹿皮蝇蛆对驯鹿机体氧化应激的影响,分别对鹿皮蝇蛆感染组和未感染组驯鹿血清中的总超氧化物歧化酶(T-SOD)、一氧化氮(NO)、谷胱甘肽过氧化物酶(GSH-Px)、丙二醛(MDA)、羟自由基(.OH)及总抗氧化能力(T-AOC)进行测定。结果表明鹿皮蝇蛆感染组血清中T-SOD、T-AOC活性、抑制.OH能力及NO含量极显著低于未感染组(P<0.01),血清中GSH-Px活性显著低于未感染组(P<0.05);血清中MDA含量极显著高于未感染组(P<0.01)。说明驯鹿感染鹿皮蝇蛆后,机体清除自由基能力降低,自由基在机体内大量蓄积,导致机体产生氧化应激反应。 相似文献

In South Bohemia a case was discovered of a yearling colt attacked by the larva of the IIIrd instar of the deer warble fly Hypoderma diana Brauer. The dead, almost mature larva of the fly was squeezed out of a subcutaneous lump above the shoulder in the first decade of April, 1985. The case is evaluated from the point of view of the possibility of the transition of specific parasites--warble flies--to another host. The attacking of a non-specific kind can occasionally occur only when there is a large number of the parasites and both kinds of host. At present the degree of attacking of deer by subcutaneous warble flies is high and therefore under favourable circumstances even domestic animals can be attacked by this type of warble fly. The above case is the first to be ascertained of a horse being attacked by a deer warble fly. 相似文献

An infection with second-stage larvae of the warble-fly H. diana in a horse is described. The second-stage larvae were incapable of developing into the third stage, because horses are unsuitable hosts and because the infected horse was treated with an insecticide. Since the horse was used for dragging trees in the forests, the infection was likely contracted via contact with H. diana, a normal parasite of roe deer in the Netherlands. 相似文献

Cattle hypodermosis (warble fly infestation) is a notorious veterinary problem throughout the world. Larvae of Hypoderma species
cause a subcutaneous myiasis of domesticated and wild ruminants. This disease is caused by, Hypoderma bovis, Hypoderma lineatum in cattle whereas, Hypoderma diana, Hypoderma actaeon, and Hypoderma tarandi, affect roe deer, red deer, and reindeer, respectively. Adults of the cattle grub are commonly known as heel flies, warble
flies, bomb flies or gad flies. The biology of hypodermosis is complex because it passes through ecto- as well as endoparasitic
stages in the life cycle. The parasitic stage of hypodermosis lasts about 1 year in domesticated as well as in the wild animals,
while in the adult stage, a free-living fly lasts only for few days. The diagnosis of hypodermosis is of prime importance
for planning treatment and the eradication program. Generally, there are two methods that are routinely used for diagnosis
of hypodermosis, i.e., the direct clinical examination and immuno diagnosis by the use of pooled serum and/or milk sample.
For the control of hypodermosis, different preparations are available and their use in most of the countries is limited to
an individual level but never cover the whole cattle population of a country. Re-infestation in the herd occurs due to the
untreated animals that remain the reservoir of the disease. The disease causes huge economic losses in animal production due
to the effect of this disease on meat, milk, and the leather industry. It can also affect the general health status as well
as the immune system of the body of the diseased animals. As regards the control measures of the disease, different methods
have been efficiently practiced and consequently this disease is controlled at national level in many European countries. 相似文献

The previous scanning electron microscopy study of the Hypoderma species suggested that Hypoderma sinense Pleske (H. sinense) was different from Hypoderma bovis (H. bovis) and Hypoderma lineatum (H. lineatum). In this study, the mitochondrial cytochrome oxidase I (COI) gene sequence of H. sinense was compared with those of the other two species. The H. sinense sequence showed only 88.3% homology to H. bovis and 88.5% to H. lineatum. The results of the sequencing analysis confirm that H. sinense is a different species from H. bovis and H. lineatum. 相似文献

In two test areas in Austria (Burgenland, Lower Austria) ivermectin has been used to control oestrinosis and hypodermosis in red- and roe deer since many years (1985 and 1987, respectively). The results until 1992, using the injectable solution Ivomec-injection 1% only, have been reported (Kutzer, 1994). In continuation of these tests Ivomec-Praemix 0.6% was examined and it turned out that the treatment was extremely successful. In practice Ivomec-Praemix 0.6% has to be given preference due to its stability. The most favourable dosage for red- and roe deer was 2 x 0.4 mg ivermectin/kg bodyweight administered at an interval of one week, although equally good results could be obtained with 1 x 0.3-0.4 mg ivermectin/kg bodyweight. With the above mentioned dosages against Pharyngomyia picta and Cephenemyia stimulator an up to 100% and against Hypoderma actaeon a 100% success of treatment could be achieved. The administration in two doses has the advantage to eradicate intestinal and lung nematodes at the same time if there are any. Finally, it was found that the controlling measures should not be interrupted for more than one year, if no treatment was done in the neighbouring hunting grounds. 相似文献

This study was carried out to investigate the prevalence and economic losses due to in cattle of hypodermosis between May
2008 and April 2009 in Afyonkarahisar province of Turkey. A total of 6,598 cattle—3,498 in pasture and 3,100 in slaughterhouse—were
examined for hypodermosis. One hundred ninety-five out of 6,598 cattle (2.96%) were found positive. Concerning this infestation
rate, the prevalence of hypodermosis in field was 5.3%, whereas the prevalence was 0.3% in slaughter house. Hypoderma bovis and Hypoderma lineatum were recorded in slaughter house. First-stage Hypoderma spp. larvae weren’t found in cattle organs in slaughterhouse. The annual economic loss on skins is estimated to be about
18,288 TL (currency exchange rate is 1 USD:1.499 TL). 相似文献

Bovine hypodermosis is a myiasis caused by Hypoderma bovis and Hypoderma lineatum (Diptera, Oestridae) larvae, which has a severe economic impact on the livestock industry. Though myiasis is widespread throughout Italy, no nationwide eradication program has ever been planned, unlike in other European Countries. With a view to setting up a national control program, a pilot study was carried out in Southern Italy on 9939 cattle bred in an area with a high prevalence of cattle hypodermosis, using moxidectin 0.5% pour-on (Cydectin, Fort Dodge) and 1% injectable (Cydectin, Fort Dodge) formulations. At the recommended dosage, moxidectin displayed efficacy levels of 99.9% in the pour-on and 100% in the injectable formulation, whereas the microdose (1 mg per head regardless of body weight) was less effective (65.7%). This trial contributed to a significant reduction in infestation rates in the study area and represented the first step through which a national program for eradicating warble fly infestation in Italy. 相似文献

A chemotherapy trial was conducted to determine the lowest dosage of injectable preparation of ivermectin against Hypoderma spp. infestation in yaks in Tibetan areas in Tianzhu county, Gansu province, in northwest of China. One hundred and sixty yaks were randomly divided into four groups of 40 yaks for the trial. The first three groups were treated by subcutaneous injection in the neck with 0.1% ivermectin (respectively, 1, 5, 10 microg/kg body weight). The fourth group was not treated and considered as control group. All the experiments were performed in November 2000 and the animals were examined for the presence of warbles in the next March and May. The results indicated that there was no warbles found on the back of treated animal while third stage larvae were palpated on back of some of the yaks in control group. It is concluded that dosage of 1 microg/kg ivermectin injectable was sufficient to kill or stop development of larvae of Hypoderma spp. in naturally infected yaks if administrated in November. 相似文献

The most variable region of the cytochrome oxidase I (COI) gene of Hypoderma bovis(1) and Hypoderma lineatum(2) (Diptera, Oestridae) was amplified by PCR and the amplicons were sequenced and analysed. PCR products were digested with three restriction enzymes, namely BfaI, HinfI and TaqI, providing informative profiles. H. bovis and H. lineatum sequences revealed an inter-specific variation rate of 8.5%, and an intra-specific variation rate of 0.87 and 0.29%, respectively. The results showed that the COI gene region examined was useful for the differentiation of H. bovis and H. lineatum and that a PCR-RFLP assay is a practical tool for their identification, offering additional diagnostic and epidemiological instruments for the study of cattle grub infestation. 相似文献

Evaluation of an antigen capture ELISA for the early diagnosis of Hypoderma lineatum in cattle under field conditions 总被引：1，自引：0，他引：1
Panadero R Vázquez L Colwell DD López C Dacal V Morrondo P Díez-Baños P 《Veterinary parasitology》2007,147(3-4):297-302
An antigen capture or sandwich ELISA (sELISA) was evaluated for the diagnosis of Hypoderma lineatum in cattle under field conditions in northwestern Spain. The kinetics of circulating hypodermin C (HyC) and specific antibodies during the course of natural infestation were determined in a group of 10 Frisian calves. In addition, oesophagi and blood samples were taken from 105 cows at a slaughterhouse in order to compare three methods for the diagnosis of H. lineatum: sandwich ELISA for the detection of the antigen HyC (sELISA), indirect ELISA for the detection of antibodies anti-HyC (iELISA) and the detection of first instars (L1) in the oesophagus. In naturally infested cattle, HyC was present in circulation at low levels during the early and late phases of the infestation. However, in the middle phase, coinciding with the presence of L1 in the oesophagus, two peaks of increased HyC concentration were observed. Specific antibodies increased progressively until the first appearance of larvae in warbles on the back. There was no correlation between antigen or antibody levels and the number of grubs in the back. Prevalence of first instars in the oesophagi of slaughtered cows was 21.9% (23/105). The percentage of cattle that were positive for circulating antigen was slightly higher (24.8%), suggesting the recent destruction of migrating larvae in some animals. However, there was no correlation between the number of L1 and HyC levels. With the iELISA, 79% of the animals were positive to Hypoderma, which means that a high percentage of those animals have been exposed to the parasite but they had no apparent current infestation. The sELISA is a good tool to follow larval development within the host; however, the episodic elevation of HyC levels limits the usefulness of this test for the early diagnosis of Hypoderma under field conditions. 相似文献

This study was carried out to investigate the prevalence of hypodermosis in cattle between January and June 2005 in Nigde
province, which is located in the middle of Turkey. A total of 1336 cattle, which were slaughtered in Nigde, were investigated
for Hypoderma larvae. The 68 out of 1336 cattle (%5.08) were found positive for Hypoderma larvae. A total of 536 Hypoderma larvae were found in the skin and subcutaneous tissue of the back of infested cattle. The 489 out of 536 larvae (%91.23)
were identified as Hypoderma bovis and 47 out of 536 (%8.77) as H. lineatum. Number of Hypoderma larvae counted on single infested cattle varied between 1–45 and the mean number of Hypoderma larvae per cattle was 7.88 (536/68). Hypodermosis was recorded for the first time in cattle from Nigde.

Chronic Wasting Disease (CWD), which had previously occurred only in the U.S.A. and Canada, broke out in a farm at Chungbuk, Korea from imported Canadian deer (Aug. 8, 2001). CWD distribution, through surveillance and epidemiologic investigations, was reported for 93 deer (43 from the CWD originating farm and 50 imported with the CWD originating farm's deer) out of 144 deer (72 from the CWD originating farm and 72 imported with the CWD originating farm's deer) that were breeding at 30 different farms. On Oct. 4 and Oct. 8, 2001, additional cases of CWD were investigated. As a result of slaughtering cohabitating deer, it was verified that other imported deer from Canada were also infected with CWD. Since it was thought that this might cause horizontal transmission, 93 deer imported from Canada in 1997 and 130 cohabitating Korean deer were slaughtered and examined. There were no infected Korean deer, but CWD re-occurred on Nov. 20, 2004 and is still under investigation. 相似文献
