Changes in haematological parameters in wild ruminants experimentally infected with Haemonchus contortus

SummaryOur study describes changes in haematological parameters in wild ruminants with parasitic infection. Six European mouflons (Ovis musimon), six fallow deer (Dama dama) and six roe deer (Capreolus capreolus) were experimentally infected with the resistant strain of the model parasite 8000 L3 Haemonchus contortus. The blood samples were collected on Day 0, 16, 37, 58, 77, and 99 of the experiment. Mild anaemia was observed in mouflons and roe deer while red blood cells increased in red blood counts (total erythrocytes, haematocrit and haemoglobin). As for the white blood cells count, leucopenia with neutrophilia and lymphopenia was recorded in mouflons, in the fallow deer and roe deer leucocytosis with neutropenia and lymphocytosis were observed. Changes in the dynamics of haematological parameters were statistically insignificant.

Liver Flukes

SummaryThe aim of the study was monitoring of liver flukes in wild ruminants including red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon) in selected regions of Slovak Republic. Between 2014 – 2016 we examined 782 faecal samples from selected wild ruminants using coprological techniques and serological methods (ELISA detection ofF. hepaticacoproantigens). None of the samples was positive for the presence ofFasciola hepatica, 5.89 % of faecal samples were positive forDicrocoelium dendriticum. Higher prevalence was recorded in mouflon (30.83 %), lower in red deer (1.49 %).D. dendriticuminfection was not determined in fallow deer and roe deer. The seasonal distribution of dicrocoeliosis indicated a highest prevalence in autumn. Significantly higher prevalence was recorded in fenced rearing when compared with open hunting grounds, suggesting that animal agglomeration, constant use of the same areas and possible stress are the main risk factors. Parasitological examination of livers of hunted wild ruminants revealed dicrocoeliosis in mouflon.

AbstractGenetic variability of the ovine parasite Haemonchus contortus from the Alpine area was investigated using mitochondrial DNA (nd4 gene), internal transcribed spacers 1 and 2 and microsatellites, in order to assess whether cross-transmission between domestic and wild ruminants occurs. The dataset was composed of 78 individual adult male H. contortus collected from chamois (Rupicapra r. rupicapra), roe deer (Capreolus capreolus), alpine ibex (Capra ibex ibex), domestic goat (Capra hircus) and sheep (Ovis aries) from different alpine areas. The data obtained show low host specificity and high genetic variation within H. contortus populations. The analyses indicate the presence of two mitochondrial haplotype clusters among host species and the absence of cryptic parasite species, confirming H. contortus as a generalist nematode and suggesting that parasite transmission between populations of domestic and wild ruminants normally occurs.

The overall objective of this study was to evaluate the hemolysing action of Naja nigricollis venom on rabbit blood. To carry out this study, three batches of three rabbits were formed with two control batches and one experimental batch. Each control lot is composed of three rabbits (males or females) while the experimental lot is composed of two males and one female. Each rabbit from the control lots was separately collected in the purple tube (EDTA) and transported to the laboratory for analysis. The rabbits from the experimental batch were also collected distinctly a few minutes after the injection of the venom of Naja nigricollis for the analysis of haematological parameters. However, before the analysis of the hematological parameters of the rabbits from the control and experimental batches, an in vitro hemolysis test of Naja nigricollis venom was performed to verify its hemolysing power. The results showed that Naja nigricollis venom has a dose-dependent in vitro hemolysing power. As for the haemogram, it revealed that the venom of Naja nigricollis has a decreasing effect on blood cells (red and white blood cells), on haemoglobin and on haematocrit, and an elevation on MGVs thus promoting anaemia.
