The activity of selected hydrolases of adult female Ascaris suum, Goeze 1782

Pubblicato online: 01 Jun 2006
Pagine: 59 - 63

Astratto

Abstract

The activity of hydrolases was measured in the perienteric fluid, muscles and three sections of the intestine of female Ascaris suum. In none of the examined samples was the activity of lipase and α-galactosidase detected. The activity of hydrolases in anterior, middle and posterior sections of the A. suum intestine was similar. The high activity of the following glucosidases: β-galactosidase (lactase), N-acetyl-β glucosaminidase and α-fucosidase, was detected in the contents and extracts from the intestinal wall, apart from the activity of those found in earlier studies. In perienteric fluid and in extracts from muscles, a high activity of β-glucuronidase and β-glucosidase was detected; such activity was not found in the intestine.

Enzymatic and protein differences between infective larvae of Trichostrongylus colubriformis conditioned or not conditioned to hypobiosis

Pubblicato online: 01 Jun 2006
Pagine: 64 - 68

Astratto

Abstract

The differences in protein and enzymatic profiles of infective larvae (L3) of Trichostrongylus colubriformis, both induced and non-induced to hypobiosis, have been evaluated by means of SDS-PAGE and densitometric analysis as well as by semiquantitative micromethod API-ZYM (Bio-Mérieux, France). Quantitative differences were identified in protein levels between the induced and non-induced larvae, where the amount of two polypeptides (200–220 kDa) decreased in range 32.3–35.4 % and the amount of six polypeptides (20–28 kDa) increased in range 20.0–27.0 % in the samples of induced larvae. In contrast to non-induced larvae, on gelatin-substrate gel in L3 in vitro released (IVR) proteases from larvae conditioned to hypobiosis, zones of proteolysis were observed between 21 and 34 kDa.

Immunological changes after multiple Toxocara canis infection of lambs

Pubblicato online: 01 Jun 2006
Pagine: 69 - 75

Astratto

Abstract

To estimate the effect of lambs’ immunoreactivity to multiple Toxocara infection, subpopulations of lymphocytes, determination of specific IgG levels, proliferation activity of splenic lymphocytes, and metabolic activity of granulocytes were performed. Five-month-old Valaška lambs were daily infected with 1000 embryonated Toxocara canis eggs for 23 days and immune responses were studied up to 49 days post infection (dpi). The number of leukocytes and neutrophiles was no significantly higher on 12 hrs pi in infected group. Absolute counts of eosinophiles were increased on 14 dpi and significantly increased on 21 d in infected animals. Greater numbers of CD2+ T lymphocytes were observed during the course of the experiment in the peripheral blood of infected animals. The level of CD4+ cells was lower 42 dpi, but the number of CD8+ cells was higher in the experimental animals. IgM positive B cells were significantly increased on 28 dpi, and monocytes on 12 hours, 14 and 35 dpi in infected animals. Production of anti-T. canis IgG was significantly enhanced on 28 dpi in infected lambs. Significant increased proliferative response of splenic T and B lymphocytes was found on 14 and 21 dpi. Metabolic burst of granulocytes demonstrated the decrease of percentage values from 3 dpi. Larvae of T. canis were microscopically observed in the peripheral blood from 14 to 35 dpi. The multiple reinfection of sheep with 1000 T. canis eggs caused eosinophilia, increased the proliferation activity of B-and T-cells and increased the production of T. canis specific antibodies. The cooperation of immune cells has directed to kill the larvae in the peripheral blood and trapping them in granulomas.

Pubblicato online: 01 Jun 2006
Pagine: 76 - 80

Astratto

Abstract

Infection with the larval stage of Echinococcus multilocularis was diagnosed in musk rat (Ondatra zibethicus) in the Slovak Republic. At necropsy, massively enlarged liver with numbers of abscess-like lesions up to 1.5 cm in diameter was found. Histological examination shoved the presence of typical multivesicular cysts with multiple protoscoleces and typical laminated layer. Polymerase chain reaction confirmed the diagnosis. According to our knowledge, this is the first documentation of Echinococcus multilocularis in naturally infected rodent in territory of the Slovak Republic.

Enterobius vermicularis infection in preschool and schoolchildren of six rural communities from a semiarid region of Venezuela: A clinical and epidemiological study

Pubblicato online: 01 Jun 2006
Pagine: 81 - 85

Astratto

Abstract

Between August 2001 and July 2002, a cross-sectional survey was conducted to investigate clinical and epidemiological data on pinworm infection among 427 preschool and primary school age children of six rural communities from the semiarid region of Falcon state, northwestern Venezuela. Children were evaluated clinically and parasitologically by the Graham method. Overall prevalence was high (63.23 %). Pinworm infection rates were not significantly different between sex or age, suggesting similar transmission pattern and risk conditions for all individuals. Among the clinical findings and children’s habits, only perianal itching, enuresis, bruxism, and finger sucking showed significant higher percentages in infected children than in uninfected. Of interest was that anal pruritus (odds ratio [OR], 2.441), finger sucking (OR, 1.901), lower socioeconomic levels (OR, 4.358) and high levels of overcrowding conditions (≥ 3 persons/room: OR, 1.878; ≥ 2 persons/bed: OR, 11.833) appeared to be significant factors associated with transmission and endemic maintenance of enterobiasis among student children in this semi-arid Venezuelan region.

Very highly prevalent Macracanthorhynchus hirudinaceus infection of wild boar Sus scrofa in Khuzestan province, south-western Iran

Pubblicato online: 01 Jun 2006
Pagine: 86 - 91

Astratto

Abstract

An epidemiological and pathological study of Macracanthorhynchus hirudinaceus infection in a total of 50 wild boars Sus scrofa attila from cane sugar fields of Iranian Khuzestan was performed. The total prevalence of 64.0 % detected is the highest hitherto known by this acanthocephalan species in wild boars and may reflect a very high contamination of the farm lands studied as the consequence of the crowding of the wild boar population in cane sugar fields. Observations prove that this species is a wild boar gut wall perforating acanthocephalan. High burdens may become so pathogenic for the host individual as to be responsible for its elimination from the population. Thus, this acanthocephalan may play a role in the control of the S. scrofa population inhabiting cane sugar fields, only lowly infected boars being able to survive. In this way, M. hirudinaceus may be useful, as the wild boar is a serious pest of field corps and, moreover, causes a variety of damage to cane sugar fields because of using them for shelter and nesting areas. Such high prevalence in wild boars and presumably high contamination of cane sugar fields represent a human infection risk for farmers, as well as for concrete ethnic group minorities in Iran. The numerous M. hirudinaceus human infection cases reported so far, mainly in Asian countries, support such a risk situation.

The role of wild boars (Sus scrofa) in circulation of trichinellosis, toxocarosis and ascariosis in the Slovak Republic

Pubblicato online: 01 Jun 2006
Pagine: 92 - 97

Astratto

Abstract

Wild boars (Sus scrofa) can play a significant role in circulation and maintenance of certain parasites in the environment. The aim of this study was to determine the seroprevalence of trichinellosis, toxocarosis and ascariosis in wild boars hunted in the Slovak Republic in 2003 and 2004. Anti-Trichinella antibodies were detected in 1.3 % out of 1035 wild boars investigated. No significant differences were observed regarding the positivity of wild boars according to age and sex in both years. The examination of 1173 wild boars for anti-Toxocara antibodies revealed 7.2 % seropositive individuals. Anti-Ascaris antibodies were detected in 6.1 % out of 411 animals examined. Both, anti-Trichinella and anti-Toxocara antibodies were determined in 0.6 % cases. Presence of anti-Trichinella and anti-Ascaris antibodies was recorded in 0.8 % animals. Concurrent infection caused with Toxocara and Ascaris was observed in 1.5 % individuals. This study concentrates on the role of wild boars in circulation and on the maintenance of trichinellosis, toxocarosis and ascariosis in the Slovak Republic.

Species of the nematode genus Amidostomum Railliet and Henry, 1909 in aquatic birds in the Netherlands

Pubblicato online: 01 Jun 2006
Pagine: 98 - 102

Astratto

Abstract

The presence of gizzard worms belonging to the genus Amidostomum was studied in birds in the Netherlands during the period 1975–2003. Amidostomum acutum was found in Anatidae: Anas acuta, A. clypeata, A. crecca, A. penelope, A. platyrynchos, A. strepera, Aythya ferina, Ay. fuligula, Ay. marila, Bucephala clangula, Melanitta fusca, M. nigra, Tadorna tadorna, Somateria mollissima and Recurvirostra avocetta. No Amidostomum species were found in the following three species of Mergini: Mergus albellus, M. merganser and M. serrator. Amidostomum anseris was seen in Anser albifrons, A. fabalis, Branta bernicla and Branta leucopsis. Amidostomum cygni was detected in Cygnus bewickii and Cygnus olor, while Amidostomum fulicae was found in Fulica atra. The prevalence is only given for bird species where ten or more individuals had been investigated: Anas platyrhynchos (n = 14): 21.4 %; Melanitta nigra (n = 12): 91.7 %; Somateria mollissima (n = 117): 100 %; Anser albifrons (n = 11): 100 % and Cygnus olor (n = 10): 60 %. Based on the present results, much more attention should be paid to the systematics, the epidemiological pattern and the pathogenicity of worms of this genus.

Occurrence of acanthocephalans in Teleost fishes of Gemlik Bay, Sea of Marmara, Turkey

Pubblicato online: 01 Jun 2006
Pagine: 103 - 108

Astratto

Abstract

The fish acanthocephalan fauna of Turkish waters is poorly known. In this study 8 fish species (Merluccius merluccius, Trachurus trachurus, Uranoscopus scaber, Gobius niger, G. cobitis, Scorpaena scrofa, Eutrigla gurnardus, Solea vulgaris) were collected from Gemlik Bay and examined for their acanthocephalan fauna. Four species not previously recorded in fish of Turkish waters were found: Solearhynchus soleae (Echinorhynchidae), Acanthhocephaloides propinquus, Paracanthocephaloides kostylewi (Arhythmacanthidae), and Longicollum pagrosomi (Pomphorhynchidae). The most common species was A. propinquus, a parasite that infects mostly gobiids (G. niger, G. cobitis). Longicollum pagrosomi was a new record for the Mediterranean basin.

Diversity of soil nematodes in meadows of the White Carpathians

Pubblicato online: 01 Jun 2006
Pagine: 109 - 116

Astratto

Abstract

Soil nematodes were studied in 11 meadow sites in the White Carpathians. In total, 155 species and 86 genera were found but the composition of nematode assemblages in eastern and western side of the mountains differed. Most nematode species belonged to the orders Tylenchida (52), Dorylaimida (35) and Rhabditida (16), and to the trophic groups bacterivores (47), plant parasites (29) and omnivores (25). In individual sites and sampling dates the number of species varied in range 18–68, genera 18–52, H’spp 1.32–3.50, H’gen 1.31–3.21, T 1.79–5.70, MI 2.32–3.63, PPI 2.03–2.98, and ΣMI 2.20–3.50. Composition of nematode assemblages and their matrix classification indicated a low degree of anthropogenous disturbance to the meadows.

Effect of mechanical disturbances on nematode communities in arable land

Pubblicato online: 01 Jun 2006
Pagine: 117 - 121

Astratto

Abstract

Nematode communities were used as bioindicators of changes in agroecosystems caused by anthropogenic factors. The aim of this study was to examine the impact of plowing and harrowing on nematode communities structure in comparison to “no tillage” treatments. The effects of mechanical disturbing of nematodes were determined on four soil treatments. Differences in nematode community structure were compared between two tillage regimes: standard tillage and no tillage. Research was conducted in 2000, in Kneževo near Osijek. Plowing had impact on increasing of bacterivorous nematodes and decreasing of fungivorous nematodes. Pratylenchus, Helicotylenchus and Tylenchus were dominant plant-feeding nematodes in no tillage treatments, while in plowing treatments Pratylenchus and Tylenchus were dominant. Abundance of Aphelenchoides decreased significantly after plowing. Tillage affected nematode communities in the soil ecosystem by changing the trophic structure and gave a decreasing, but not statistically significant, trend in MI.

The examination of 1173 wild boars for anti-Toxocara antibodies revealed 7.2 % seropositive individuals. Anti-Ascaris antibodies were detected in 6.1 % out of 411 animals examined. Both, anti-Trichinella and anti-Toxocara antibodies were determined in 0.6 % cases. Presence of anti-Trichinella and anti-Ascaris antibodies was recorded in 0.8 % animals. Concurrent infection caused with Toxocara and Ascaris was observed in 1.5 % individuals. This study concentrates on the role of wild boars in circulation and on the maintenance of trichinellosis, toxocarosis and ascariosis in the Slovak Republic.

Species of the nematode genus Amidostomum Railliet and Henry, 1909 in aquatic birds in the Netherlands

Pubblicato online: 01 Jun 2006
Pagine: 98 - 102

Astratto

Abstract

The presence of gizzard worms belonging to the genus Amidostomum was studied in birds in the Netherlands during the period 1975–2003. Amidostomum acutum was found in Anatidae: Anas acuta, A. clypeata, A. crecca, A. penelope, A. platyrynchos, A. strepera, Aythya ferina, Ay. fuligula, Ay. marila, Bucephala clangula, Melanitta fusca, M. nigra, Tadorna tadorna, Somateria mollissima and Recurvirostra avocetta. No Amidostomum species were found in the following three species of Mergini: Mergus albellus, M. merganser and M. serrator. Amidostomum anseris was seen in Anser albifrons, A. fabalis, Branta bernicla and Branta leucopsis. Amidostomum cygni was detected in Cygnus bewickii and Cygnus olor, while Amidostomum fulicae was found in Fulica atra. The prevalence is only given for bird species where ten or more individuals had been investigated: Anas platyrhynchos (n = 14): 21.4 %; Melanitta nigra (n = 12): 91.7 %; Somateria mollissima (n = 117): 100 %; Anser albifrons (n = 11): 100 % and Cygnus olor (n = 10): 60 %. Based on the present results, much more attention should be paid to the systematics, the epidemiological pattern and the pathogenicity of worms of this genus.

Occurrence of acanthocephalans in Teleost fishes of Gemlik Bay, Sea of Marmara, Turkey

Pubblicato online: 01 Jun 2006
Pagine: 103 - 108

Astratto

Abstract

The fish acanthocephalan fauna of Turkish waters is poorly known. In this study 8 fish species (Merluccius merluccius, Trachurus trachurus, Uranoscopus scaber, Gobius niger, G. cobitis, Scorpaena scrofa, Eutrigla gurnardus, Solea vulgaris) were collected from Gemlik Bay and examined for their acanthocephalan fauna. Four species not previously recorded in fish of Turkish waters were found: Solearhynchus soleae (Echinorhynchidae), Acanthhocephaloides propinquus, Paracanthocephaloides kostylewi (Arhythmacanthidae), and Longicollum pagrosomi (Pomphorhynchidae). The most common species was A. propinquus, a parasite that infects mostly gobiids (G. niger, G. cobitis). Longicollum pagrosomi was a new record for the Mediterranean basin.

Diversity of soil nematodes in meadows of the White Carpathians

Pubblicato online: 01 Jun 2006
Pagine: 109 - 116

Astratto

Abstract

Soil nematodes were studied in 11 meadow sites in the White Carpathians. In total, 155 species and 86 genera were found but the composition of nematode assemblages in eastern and western side of the mountains differed. Most nematode species belonged to the orders Tylenchida (52), Dorylaimida (35) and Rhabditida (16), and to the trophic groups bacterivores (47), plant parasites (29) and omnivores (25). In individual sites and sampling dates the number of species varied in range 18–68, genera 18–52, H’spp 1.32–3.50, H’gen 1.31–3.21, T 1.79–5.70, MI 2.32–3.63, PPI 2.03–2.98, and ΣMI 2.20–3.50. Composition of nematode assemblages and their matrix classification indicated a low degree of anthropogenous disturbance to the meadows.

Effect of mechanical disturbances on nematode communities in arable land

Pubblicato online: 01 Jun 2006
Pagine: 117 - 121

Astratto

Abstract

Nematode communities were used as bioindicators of changes in agroecosystems caused by anthropogenic factors. The aim of this study was to examine the impact of plowing and harrowing on nematode communities structure in comparison to “no tillage” treatments. The effects of mechanical disturbing of nematodes were determined on four soil treatments. Differences in nematode community structure were compared between two tillage regimes: standard tillage and no tillage. Research was conducted in 2000, in Kneževo near Osijek. Plowing had impact on increasing of bacterivorous nematodes and decreasing of fungivorous nematodes. Pratylenchus, Helicotylenchus and Tylenchus were dominant plant-feeding nematodes in no tillage treatments, while in plowing treatments Pratylenchus and Tylenchus were dominant. Abundance of Aphelenchoides decreased significantly after plowing. Tillage affected nematode communities in the soil ecosystem by changing the trophic structure and gave a decreasing, but not statistically significant, trend in MI.
