The risk to human health related to disposal of animal wastes to soil — microbiological and parasitical aspects

Pubblicato online: 22 Feb 2014
Pagine: 147 - 154

Astratto

Abstract

The study was conducted to investigate the microbiological and parasitical risk related to the disposal of animal manure to soil by storage of raw pig slurry at temperatures 4 °C, 20 °C and 42 °C for 115 days. Plate counts of Salmonella typhimurium and number of devitalized non-embryonated model Ascaris suum eggs were determined on days 0, 7, 12, 22, 32, 40, 55, 90 and 115 of storage. At the same intervals level of selected physico-chemical parameters were determined. Microbiological examination showed that S. typhimurium survived in the slurry for less than 115 days at 4 °C and less than 90 days at 20 °C and 42 °C. Devitalization of A. suum eggs increased with temperature and time of storage, but complete devitalization was not achieved even after 115 days at 42 °C. Physico-chemical parameters showed changes related to decomposition processes, but did not allow us to draw definite conclusion regarding their influence on devitalization of pathogens. The results indicate potential risk to human food chain that can be prevented by strict observation of legislative provisions and appropriate treatment of animal manure.

Abstract

Helminths were examined in 292 wild rabbits (Oryctolagus cuniculus) collected in Tenerife, Fuerteventura, La Palma and El Hierro islands, and La Graciosa islet (Canary Islands, Spain), from 2008 to 2012. Three species of cestodes, Taenia pisiformis (Taeniidae), Andrya cuniculi and Neoctenotaenia ctenoides (Anoplocephalidae), and three species of nematodes Trichostrongylus retortaeformis (Trichostrongylidae), Passalurus ambiguus (Oxyuridae) and Calodium hepaticum (Capillariidae), were identified. Only 2 species (N. ctenoides and P. ambiguus) were regularly present in all the islands, with an average prevalence above 50 %. Possible causes of the present distribution of helminths are commented. Insular and founder effects on parasite species in isolated ecosystems are demonstrated. The finding of the zoonotic species C. hepaticum solely in La Palma, represents a novel identification of this nematode in O. cuniculus in the Canary Islands.

Abstract

Objective of the work was to study a potential association between trematode infections in pregnant ewes and concentrations β-hydroxybutyrate, which is a ketone body found in animals with pregnancy toxaemia. After administration of a long-acting nematocide, 80 pregnant sheep, infected with trematodes, were allocated as follows; primigravidae ewes in group P-A remained untreated and in group P-B were given netobimin; multigravidae ewes in group M-A remained untreated, in group M-B were given netobimin and in group M-C were given rafoxanide. We collected faecal samples for trematode epg counting and blood samples for measurement of β-hydroxybutyrate concentrations. Mean faecal epg counts of D. dendriticum and F. hepatica decreased significantly after netobimin administration; mean faecal epg counts of F. hepatica, but not of D. dendriticum, decreased significantly after rafoxanide administration. Between P-A and P-B, the difference in mean blood β-hydroxybutyrate concentrations was significant (P = 0.036) immediately after lambing. Between M-A or M-C and M-B, it was significant (P ≤ 0.002) 28 days after trematocide administration and immediately after lambing; between M-A and M-C, no significant difference was evident. Immediately after lambing, mean blood β-hydroxybutyrate concentration in primiparous/multiparous ewes with Dicrocoelium faecal output ≤150 epg was 0.21/0.64 mmol L−1, respectively, and in primiparous/multiparous ewes with Dicrocoelium faecal output >150 epg was 0.40/0.93 mmol L−1, respectively (P = 0.704/<0.001, respectively). Mean blood β-hydroxybutyrate concentration in group P-C/M-C ewes with Fasciola faecal output of <16/<30 epg was 0.47/0.68 mmol L−1, respectively; that in group P-C/M-C ewes with Fasciola faecal output of ≥16/≥30 epg was 0.56/0.85 mmol L−1, respectively (P = 0.620/0.278, respectively). The results indicate that more trematode-infected adult ewes were found to have increased β-hydroxybutyrate blood concentrations and point out to a potential role of liver trematode infections in predisposing adult ewes to pregnancy toxaemia.

Abstract

The aim of our study was to determine prevalence of appearance of Fasciola hepatica L. among European bison Bison bonasus selected in Białowieża National Park, Poland from 2001 to 2006. The analyzed ITS-1 and ITS-2 sequences of nuclear DNA of Fasciola hepatica have a length of 433bp and an AT content of 47.8 % and a length of 365 bp and an AT content of 51.2 % respectively. Among 178 bison liver fluke was found in liver of 63 (35.3 %) individuals including as follow: in 39 (21.9 %) adults, 11 (6.1 %) juveniles and 13 (7.3 %) calves. Results of researches are as follow: prevalence of infection of Fasciola hepatica among bison in Białowieża National Park between 2001–2006 oscillated about 35.3%. The most extensive invasion of fascioliasis was observed in adult animals (21.9 %). We pay attention that between infected animals were calves 13 (7.3 %). Conclusions: The obtained results referring to infection of bison within the Białowieża National Park, Poland of F. hepatica are very interesting. The epidemiological importance of these finding is evident, demonstrating the fascioliasis expansion in restricted or protected areas, as National Parks such as Białowieża National Park, habitat of this wild host, and where no domestic animals are present.

Abstract

Species composition and structure of strongylid (Nematoda: Strongylidae) community were examined in 15 plains zebras (Equus burchelli) and 8 Grevy’s zebra (Equus grevyi) kept in the “Askania-Nova” Biosphere Reserve (Ukraine). Strongylids were collected from zebras in vivo following deworming with the “Univerm” (0.2 % aversectin C, Russia). Twenty-two strongylid species (3 species of subfamily Strongylinae and 19 — of Cyathostominae) were found. In plains zebras, 21 strongylid species were found; from 3 to 14 species per host. In Grevy’s zebras, 18 strongylid species were recorded; from 4 to 14 species per host. Cyathostominae dominated in the communities of both zebra species; they composed more then 99 % of strongylid number. Comparison of strongylid biodiversity in plains zebras from the “Askania-Nova” reserve with data collected from four African countries showed low similarity of strongylid faunas in zebras from Ukraine and Africa; the strongylid community was similar to those of domestic ponies from the same area.

Abstract

Post-mortem examination of a sub-adult debilitated white stork (Ciconia ciconia) from southern Italy showed nodular enteritis associated with massive infection by Chaunocephalus ferox (Digenea: Echinostomatidae). Pathological changes included lesions ranging from traumatic destruction of tissues with hemorrhages and thickness of mucosa and submucosa at fluke penetration site to loss of duodenal villi and necrosis. Lesions through the whole intestinal tract associated with the digenean infection were considered as compatible with causing the cachexia and death of the white stork.

Abstract

For first time, 3 species of prosobranchial snails (Bithynia fuchsiana, Parafossarulus striatulus (Bithyniidae) and Melanoides tuberculata (Thiaridae)) from North Vietnam were studied for presence of the parthenitae and cercariae of Trematoda. The morphology of 12 species of larvae belonging to 8 families (Cyathocotylidae, Pleurogenidae, Lecithodendriidae, Paramphistomidae, Heterophyidae, Notocotylidae, Psilostomidae and Echinostomatidae) was described. Data on the life cycles of 3 species (Echinochasmus japonicus, Notocotylus intestinalis and Sphaeridiotrema monorchis) as well as molecular data on 28S rDNA were obtained. There was no intraspecific variability found in any of the sequences examined. The 28S rDNA sequence length determined for N. intestinalis was 1315 bp, while that of S. monorchis was 1292 bp, and that of E. japonicus was 1288 bp.

The influence of Western corn rootworm seed coating and granular insecticides on the seasonal fluctuations of soil nematode communities in a maize field

Pubblicato online: 22 Feb 2014
Pagine: 205 - 214

Abstract

Western corn rootworm, Diabrotica virgifera virgifera, is a pest that needs to be controlled with chemicals in the maize monoculture. The aim of this study was to examine the influence of insecticides on nematode communities in a maize field. Four soil treatments were used in this experiment: variant 1 — a granular application with tefluthrin (199.5 g a.i./ha); variant 2 — a granular application with clothianidin (110 g a.i./ha); variant 3 — a seed treatment with clothianidin (1.25 μg a.i/seed); and control — a maize field without insecticides.

During the investigated period, a total of 19 117 soil nematode individuals were captured and 9 orders, 33 genera and 37 species were identified. Acrobeloides nanus, Cephalobus persegnis, Eucephalobus striatus and Basiria gracilis were the dominant species, accounting for 48 % of the total number of individuals. The mean abundance and species diversity index were significantly lower for variant 2. Bacterial feeders were the dominant trophic group for all 4 variants. The numbers of nematodes in particular trophic groups (i.e., bacterial feeders, fungal feeders and omnivores) were significantly different between variant 2 and the control. The Σ Maturity index, Maturity index and Plant parasitic index did not show significant differences among the variants. The higher values of the Enrichment and Structure indices were observed in the first month of the investigation in all 4 variants. A cluster analysis showed that nematode species population densities were strongly affected by the date of soil sample collection and by the variants used in the experiment.

Abstract

Additional data on the occurrence and distribution of Xiphinema non-americanum group species in Romania are provided. Xiphinema diversicaudatum, X. index, X. vuittenezi and X. italiae were recovered from vineyards and cherry fruit trees; adults and juvenile stages were described and analysed and the morphology/variability discussed. Multiplex PCR diagnostic test using species-specific primers designed by Wang et al. (2003) yielded amplification products with expected lengths for all screened populations of these four species. Two ribosomal markers (D2-D3 28 LSU rDNA and ITS) were sequenced and ITS RFLP patterns were obtained from two X. vuittenezi populations, which have shown some morphological differences. Comparatively low level of interpopulation genetic dissimilarity (<1 %) was revealed for both markers (for D2D3 — 0.5 %; for ITS — 0.7 %). Both populations of X. vuittenezi studied produced identical ITS-RFLP specific pattern that clearly identify this species.

Treatment failure of ivermectin for Oxyuris equi in naturally infected ponies in Czech Republic

Pubblicato online: 22 Feb 2014
Pagine: 232 - 234

Astratto

Abstract

Nine ponies (20 months of age) with naturally acquired cyathostome and pinworm infections were treated orally with ivermectin at a dosage of 400 μg /kg. Ivermectin was highly effective on the cyathostome infection. However, adult Oxyuris equi were present in six horses. In recent years, anthelmintic treatment with macrocyclic lactones have not appeared to deliver the expected efficacy against equine pinworms (Oxyuris equi) in the USA. This is the first European study to demonstrate anthelmintic resistance in Oxyuris equi to macrocyclic lactones in naturally infected ponies (Czech Republic).

Twenty-two strongylid species (3 species of subfamily Strongylinae and 19 — of Cyathostominae) were found. In plains zebras, 21 strongylid species were found; from 3 to 14 species per host. In Grevy’s zebras, 18 strongylid species were recorded; from 4 to 14 species per host. Cyathostominae dominated in the communities of both zebra species; they composed more then 99 % of strongylid number. Comparison of strongylid biodiversity in plains zebras from the “Askania-Nova” reserve with data collected from four African countries showed low similarity of strongylid faunas in zebras from Ukraine and Africa; the strongylid community was similar to those of domestic ponies from the same area.

Abstract

Post-mortem examination of a sub-adult debilitated white stork (Ciconia ciconia) from southern Italy showed nodular enteritis associated with massive infection by Chaunocephalus ferox (Digenea: Echinostomatidae). Pathological changes included lesions ranging from traumatic destruction of tissues with hemorrhages and thickness of mucosa and submucosa at fluke penetration site to loss of duodenal villi and necrosis. Lesions through the whole intestinal tract associated with the digenean infection were considered as compatible with causing the cachexia and death of the white stork.

Abstract

The new cyclophyllidian species Wardium mackoifusa sp. n. (Aploparksidae Mayhew 1925), in the little gull (Larus minutus Pall.) from Ukraine is described. The species is characterized by 10 aploparaksoid hooks, each 13–15 μm long. It noticeably differs from all of the species of this genus by the shape and the armament of the cirrus and the presence of polar delicate filaments on the embryophore of eggs.

Abstract

For first time, 3 species of prosobranchial snails (Bithynia fuchsiana, Parafossarulus striatulus (Bithyniidae) and Melanoides tuberculata (Thiaridae)) from North Vietnam were studied for presence of the parthenitae and cercariae of Trematoda. The morphology of 12 species of larvae belonging to 8 families (Cyathocotylidae, Pleurogenidae, Lecithodendriidae, Paramphistomidae, Heterophyidae, Notocotylidae, Psilostomidae and Echinostomatidae) was described. Data on the life cycles of 3 species (Echinochasmus japonicus, Notocotylus intestinalis and Sphaeridiotrema monorchis) as well as molecular data on 28S rDNA were obtained. There was no intraspecific variability found in any of the sequences examined. The 28S rDNA sequence length determined for N. intestinalis was 1315 bp, while that of S. monorchis was 1292 bp, and that of E. japonicus was 1288 bp.

The influence of Western corn rootworm seed coating and granular insecticides on the seasonal fluctuations of soil nematode communities in a maize field

Pubblicato online: 22 Feb 2014
Pagine: 205 - 214

Abstract

Western corn rootworm, Diabrotica virgifera virgifera, is a pest that needs to be controlled with chemicals in the maize monoculture. The aim of this study was to examine the influence of insecticides on nematode communities in a maize field. Four soil treatments were used in this experiment: variant 1 — a granular application with tefluthrin (199.5 g a.i./ha); variant 2 — a granular application with clothianidin (110 g a.i./ha); variant 3 — a seed treatment with clothianidin (1.25 μg a.i/seed); and control — a maize field without insecticides.

During the investigated period, a total of 19 117 soil nematode individuals were captured and 9 orders, 33 genera and 37 species were identified. Acrobeloides nanus, Cephalobus persegnis, Eucephalobus striatus and Basiria gracilis were the dominant species, accounting for 48 % of the total number of individuals. The mean abundance and species diversity index were significantly lower for variant 2. Bacterial feeders were the dominant trophic group for all 4 variants. The numbers of nematodes in particular trophic groups (i.e., bacterial feeders, fungal feeders and omnivores) were significantly different between variant 2 and the control. The Σ Maturity index, Maturity index and Plant parasitic index did not show significant differences among the variants. The higher values of the Enrichment and Structure indices were observed in the first month of the investigation in all 4 variants. A cluster analysis showed that nematode species population densities were strongly affected by the date of soil sample collection and by the variants used in the experiment.

Abstract

Additional data on the occurrence and distribution of Xiphinema non-americanum group species in Romania are provided. Xiphinema diversicaudatum, X. index, X. vuittenezi and X. italiae were recovered from vineyards and cherry fruit trees; adults and juvenile stages were described and analysed and the morphology/variability discussed. Multiplex PCR diagnostic test using species-specific primers designed by Wang et al. (2003) yielded amplification products with expected lengths for all screened populations of these four species. Two ribosomal markers (D2-D3 28 LSU rDNA and ITS) were sequenced and ITS RFLP patterns were obtained from two X. vuittenezi populations, which have shown some morphological differences. Comparatively low level of interpopulation genetic dissimilarity (<1 %) was revealed for both markers (for D2D3 — 0.5 %; for ITS — 0.7 %). Both populations of X. vuittenezi studied produced identical ITS-RFLP specific pattern that clearly identify this species.

Treatment failure of ivermectin for Oxyuris equi in naturally infected ponies in Czech Republic

Pubblicato online: 22 Feb 2014
Pagine: 232 - 234

Astratto

Abstract

Nine ponies (20 months of age) with naturally acquired cyathostome and pinworm infections were treated orally with ivermectin at a dosage of 400 μg /kg. Ivermectin was highly effective on the cyathostome infection. However, adult Oxyuris equi were present in six horses. In recent years, anthelmintic treatment with macrocyclic lactones have not appeared to deliver the expected efficacy against equine pinworms (Oxyuris equi) in the USA. This is the first European study to demonstrate anthelmintic resistance in Oxyuris equi to macrocyclic lactones in naturally infected ponies (Czech Republic).
