Prevalence of intestinal parasites in children from minority group with low hygienic standards in Slovakia

Pubblicato online: 11 Apr 2012
Pagine: 63 - 66

Astratto

Abstract

The number of parasites followed the rapid growing of human population worldwide, not only in developing but also in developed countries. Many of them are diagnosed in children and adolescents. The occurrence of selected intestinal endoparasites in children coming from areas with low hygienic and socioeconomic status was studied. Out of 81 faecal samples examined, 46 (56.8 %) were positive for presence of intestinal parasites. From helminths, Ascaris lumbricoides was found to be the leading parasite (24.7 %), followed by Trichuris trichiura (17.3 %). Tapeworm Taenia spp. eggs were detected in 4.9 % of examined children. From protozoan parasites Cryptosporidium spp. was observed in 36 children (44.4 %) and Giardia intestinalis in 20 children (24.7 %). The occurrence of these epidemiologically low risky parasites in Roma children population suggests low hygienic standard in the Roma settlements.

Suitability of different tissue fixatives for subsequent PCR analysis of Cysticercus ovis

Pubblicato online: 11 Apr 2012
Pagine: 67 - 70

Astratto

Abstract

PCR amplification of specific DNA regions is a powerful tool for retrospective studies, but not all preservation or fixation methods render DNA that is suitable for subsequent amplification. Several factors affect sensitivity of polymerase chain reaction (PCR) amplification. There were reported the effects of commonly used fixation solutions — 10 % neutral buffered formalin, 20 % neutral buffered formalin and Carnoy’s solution and the efficiency of PCR amplification in fresh tissue and paraffin (or wax) embedded samples of Cysticercus ovis. DNA from samples was isolated and PCR product of 1300 bp was amplified. Results indicated that the samples fixed in Carnoy’s solution produced reliable amplification of desired fragments. The samples that were fixed in 10 % and 20 % neutral buffered formalin brought negative results.

Lepus corsicanus gastro-intestinal helminths: first report

Pubblicato online: 11 Apr 2012
Pagine: 71 - 77

Astratto

Abstract

Italian hare Lepus corsicanus De Winton, 1898, is a true species living in simpatry with Lepus europaeus in mainland Italy and with Oryctolagus cuniculus in Sicily, where L. europaeus is absent. Up to date, nobody has studied the helminths of this endemic Italian Mammal. Therefore, in order to describe Italian hare gastro-intestinal helminths, gastro-intestinal tract of 29 Italian hares, coming from mainland Italy (#14) and from Sicily (#15) were collected between 1997 and 2009. Twentyfive hares were positive for at least one parasite (86 %). Six parasite species were isolated, 2 cestodes (Cittotaenia pectinata, prevalence 3 %) and Paranoplocephala sp., 3 %) and 4 nematodes (Trichostrongylus retortaeformis, 86 %, Graphidium strigosum, 14 %, Trichuris sp., 10 % and Teladorsagia circumcincta, 7 %). Both Teladorsagia circumcincta circumcincta and Teladorsagia circumcincta trifurcata morphotypes were identified. Comparison with available data regarding L. europaeus and O. cuniculus in Italy is provided. Being not T. circumcincta and Paranoplocephala sp. typical parasites of leporids, a description of the observed specimens is given.

Black grouse in Czech Republic and its parasites

Pubblicato online: 11 Apr 2012
Pagine: 78 - 81

Astratto

Abstract

According to the newest data (2010), the state of the black grouse is in decline in the Czech Republic. One of the reasons for this decline is the parasitic infection. The examination of 170 faecal specimens disclosed 6 species of parasites. Helminth eggs were found in 50 % of the examined faecal specimens. The following eggs were found: cestode Hymenolepis spp. (28 %), with the highest prevalence (84 %) and mean intensity (1076 EPG) in spring; nematodes Trichostrongylus tenuis (24 %), and Ascaridia compar (3 %) with a mean intensity of 11 and 12 EPG, respectively. Coccidia infections were present in 1 % of faecal specimens only in spring, with an intensity of 35 OPG. However, in the following year, Eimeria lyruri was the most abundant parasite in the faecal specimens. During the second year of our research, the prevalence of E. lyruri was 28 %; the highest prevalence (67 %) was in summer with an intensity of up to 9433 OPG.

Redescription of Echinuria hypognatha Wehr, 1937 (Nematoda; Acuariidae) including ecology and new hosts

Pubblicato online: 11 Apr 2012
Pagine: 82 - 86

Astratto

Abstract

Reports on the presence of Echinuria hypognatha Wehr, 1937 in Europe have so far provided only general information, and therefore we present further morphometric and ecological characteristics of this parasite. In this study, the examined nematodes were isolated from the digestive tract of 1 005 wild ducks, representing 17 species from the northwestern Poland. The anatomical features of the parasite were in principle consistent with the description of the species by its discoverer and reports in the available literature. Nematodes (505 individuals) were found in 2.5 % of the examined ducks, in five species wintering in Poland: Clangula hyemalis, Melanitta nigra, M. fusca, Mergellus albellus and Aythya fuligula. The exclusive locations of the nematode were the glands in the proventriculus. The highest incidence was recorded in Melanitta ducks, and the presence of this nematode only in birds wintering in Poland indicates that E. hypognatha is brought to Poland by birds migrating from the areas of Eastern Siberia.

Abstract

In this paper, the occurrence and new morphological data of Unilatus unilatus Mizelle et Kritsky, 1967 from the gills of Hypostomus strigaticeps (Regan, 1907), Hypostomus regani (Ihering, 1905), and Hypostomus iheringii (Regan, 1908) from the Chavantes reservoir, São Paulo State, Brazil are reported. Unilatus unilatus from this reservoir presents differences in relation to the holotype previously described such as, eggs with no bifid or trifid filament and a rounded termination, anterior bar slightly curved with a posterior projection, and posterior bar which may present three shapes. This is the first record of U. unilatus in southeastern Brazil outside the Amazon River Basin, with H. strigaticeps, H. regani and H. iheringii as new hosts.

The pinewood nematode, Bursaphelenchus xylophilus, in Madeira Island

Pubblicato online: 11 Apr 2012
Pagine: 96 - 103

Astratto

Abstract

The environmental conditions in Madeira Island are favorable for the presence and dissemination of the pinewood nematode (PWN), Bursaphelenchus xylophilus. Five hundred Pinus pinaster wood samples were collected in several forest areas and PWN was detected in 22.8 % of the samples. Bursaphelenchus xylophilus isolates from Madeira Island displayed the species-specific diagnostic characters. A morphological variation in the female tail terminus was detected. In most females, the tail presented a broadly rounded terminus and, occasionally, a digitate terminus with a terminal nipple-like extension resembling a mucro. PCR ITS-RFLP analysis revealed that Madeira Island isolates exhibited patterns specific to the species B. xylophilus and similar to virulent isolates. Amplified ITS regions were further sequenced and no genetic diversity was found for this genomic region among 17 Portuguese isolates (Madeira Island and Continental Portugal). Phylogenetic analysis revealed that Portuguese isolates grouped with isolates from China, Korea and one isolate from Japan.

First record of Longidorus danuvii Barsi, Lamberti and De Luca, 2007 (Nematoda: Longidoridae) from Poland with description of pathologies of the lip region and reproductive system

Pubblicato online: 11 Apr 2012
Pagine: 104 - 107

Astratto

Abstract

Up to date, fourteen species of the genus Longidorus have been recorded from Poland. During a recent survey, L. danuvii Barsi, Lamberti and De Luca, 2007 was found for the first time. It is also the first record outside Serbia, from where it was described. Among normal females two pathological specimens were found: one bivulval with abnormal structure of the genital tract and one with deformated lip region. Description of both normal and pathological females is provided. Normal females are similar to populations from Serbia, the main difference is shorter tail in population from Poland (41.6 vs 46.4 and 46.5) and lower c′ value (1.60 vs 1.70 and 1.85).

Nematicidal effect of chestnut tannin solutions on the potato cyst nematode Globodera rostochiensis (Woll.) Barhens

Pubblicato online: 11 Apr 2012
Pagine: 108 - 114

Astratto

Abstract

Recently, tannins have been reported for their nematicidal activity against the root-knot nematode Meloidogyne javanica both in vitro and in pot experiments in addition to a biocidal effect on a wide range of fungi, bacteria and yeasts. However, no information is available on the effect of these polyphenols on plant parasitic cyst nematodes. Therefore, an in vitro and a pot experiments on potato were undertaken to investigate the nematicidal activity of tannin aqueous solutions at different concentrations on the potato cyst nematode Globodera rostochiensis. In the in vitro experiment different tannin concentrations in a geometric scale (from 0.32 to 20.48 g/l) were tested for their effect on the egg hatch of the nematode. All tested tannin concentrations were effective to reduce egg viability from 56 to 87%, in comparison to the untreated control. In the pot experiment, tannins, as aqueous solutions at rates of 100, 250 and 450 g/m2, were applied to soil at two different application times (at sowing and at sowing and two weeks later). All tested doses were effective to reduce the number of cyst/100 g soil, eggs and juveniles/g soil and reproduction rate in comparison to untreated control. The number of eggs and juveniles/cyst was not influenced by the different applied rates of tannins.

Subconjunctival infestation with Setaria

Pubblicato online: 11 Apr 2012
Pagine: 119 - 121

Astratto

Abstract

Most cases of human subconjunctival infestations with nematodes described in the literature belong to the genus Dirofilaria. This is a report of subconjunctival setariasis in a 65 years old man, diagnosed 2 years after a travel to Singapore. The parasite was removed immediately from the subconjunctival space and the patient was administered topical antibiotic and anti-inflammatory eye drops. The complete remission of symptoms and signs was noted. The parasite was identified on optical microscopy as belonging to the genus Setaria. The life cycle of the parasite and the accidental human contamination are described. The presence of a moving worm under the human conjunctiva is a rare condition that requires urgent action, in order to prevent its migration into less accessible locations. Since the human subject is a dead-end host who does not allow the multiplication of the parasite, its surgical removal is the only cure.

Abstract

Up to date, fourteen species of the genus Longidorus have been recorded from Poland. During a recent survey, L. danuvii Barsi, Lamberti and De Luca, 2007 was found for the first time. It is also the first record outside Serbia, from where it was described. Among normal females two pathological specimens were found: one bivulval with abnormal structure of the genital tract and one with deformated lip region. Description of both normal and pathological females is provided. Normal females are similar to populations from Serbia, the main difference is shorter tail in population from Poland (41.6 vs 46.4 and 46.5) and lower c′ value (1.60 vs 1.70 and 1.85).

Abstract

Recently, tannins have been reported for their nematicidal activity against the root-knot nematode Meloidogyne javanica both in vitro and in pot experiments in addition to a biocidal effect on a wide range of fungi, bacteria and yeasts. However, no information is available on the effect of these polyphenols on plant parasitic cyst nematodes. Therefore, an in vitro and a pot experiments on potato were undertaken to investigate the nematicidal activity of tannin aqueous solutions at different concentrations on the potato cyst nematode Globodera rostochiensis. In the in vitro experiment different tannin concentrations in a geometric scale (from 0.32 to 20.48 g/l) were tested for their effect on the egg hatch of the nematode. All tested tannin concentrations were effective to reduce egg viability from 56 to 87%, in comparison to the untreated control. In the pot experiment, tannins, as aqueous solutions at rates of 100, 250 and 450 g/m2, were applied to soil at two different application times (at sowing and at sowing and two weeks later). All tested doses were effective to reduce the number of cyst/100 g soil, eggs and juveniles/g soil and reproduction rate in comparison to untreated control. The number of eggs and juveniles/cyst was not influenced by the different applied rates of tannins.

Subconjunctival infestation with Setaria

Pubblicato online: 11 Apr 2012
Pagine: 119 - 121

Abstract

Most cases of human subconjunctival infestations with nematodes described in the literature belong to the genus Dirofilaria. This is a report of subconjunctival setariasis in a 65 years old man, diagnosed 2 years after a travel to Singapore. The parasite was removed immediately from the subconjunctival space and the patient was administered topical antibiotic and anti-inflammatory eye drops. The complete remission of symptoms and signs was noted. The parasite was identified on optical microscopy as belonging to the genus Setaria. The life cycle of the parasite and the accidental human contamination are described. The presence of a moving worm under the human conjunctiva is a rare condition that requires urgent action, in order to prevent its migration into less accessible locations. Since the human subject is a dead-end host who does not allow the multiplication of the parasite, its surgical removal is the only cure.
