SEM studies on the copulatory apparatus of male Oesophagostomum columbianum

Pubblicato online: 01 Mar 2006
Pagine: 3 - 5

Astratto

Abstract

SEM studies on the cloacal opening of Oesophagostomum columbianum indicate that it is located on a raised conical structure called the “genital cone”. The genital cone is provided with a ventral lip and a pair of subdorsal gential appendages. The vental lip is a triangular structure having a single papilla on it and the genital appendages are covered with wrinkled cuticle with a nerve process projecting to the exterior in center. The bursa is supported by muscular rays which end up as knob-like sessile genital papillae. The inner surface of the bursa is porous. Spicules are two, equal, each provided with an ala which decreases in height distally and end up much prior to the spicular tip.

Congenital transmission of Trichinella spiralis in experimentally infected mice

Pubblicato online: 01 Mar 2006
Pagine: 7 - 10

Astratto

Abstract

Congenital transmission of T. spiralis infectio in BALB/c mice was studied. Pregnant mice were each infected with 300 larvae 5, 7, 15 and 17 days after fertilization. Newborn mice were examined by artificial digestion of muscles. Out of 6 offspring born to the mother-mouse infected 7 days after fertilization, two offspring were found to be infected, 7 and 24 larvae were recovered respectively. Other 7 female mice were first infected with T. spiralis larvae and then gestated, only the offspring born to the mother-mice fertilized 8 and 22 days after infection were found to be infected with a larval burden ranging from 1–3 larvae per animal. All of the larvae recovered from the offspring were the non-encapsulated larvae. The cross-fostering in which one-day old young born to healthy mother-mice were nursed by infected mothers for 21 days, showed that no young were found to be infected. These findings showed that tansplacental transmission of T. spiralis could occur in mice, if the female were infected during mid-pregnancy or fertilized in 1 month after infection (e.g., infected in one month before fertilization). The larvae transmitted from maternal-to-neonatal mice may be migrating. Transmammary transmission of T. spiralis was not observed.

DOT-ELISA and parasitological examination for diagnosis of Schistosoma mansoni infection in Nigeria

Pubblicato online: 01 Mar 2006
Pagine: 11 - 15

Astratto

Abstract

Schistosoma mansoni infection constitutes significant economic and public health consequences. Accurate diagnosis of the infection is imperative in order to identify subjects needing care in the broadest sense. In this study the dot-ELISA and direct parasitological method were compared in the diagnosis of S. mansoni infection in Jos, Nigeria. Of the 106 subjects studied 64.2 % were S. mansoni positive serologically while only 10.4 % of them were found to have the parasite’s egg in their stools. Individuals aged 20–29 years of both sexes had highest prevalence of 73.9 % and 21.7% by serological and parasitological diagnosis respectively. Prevalence of infection among males was 13.5 % and 7.4 % among females by parasitology. By serology the corresponding figures were 59.6 % and 68.5 % respectively. No significant difference was observed by parasitology (χ2=4.534, P ≤ 0.05) and by serology (χ2=2.00, P ≤ 0.05). Results advocate for serodiagnostic technique over parasitological method in S. mansoni surveillance and epidemiological studies.

Evaluation of a coproantigen enzyme-linked immunosorbent assay for the diagnosis of canine echinococcosis in Iran

Pubblicato online: 01 Mar 2006
Pagine: 17 - 19

Astratto

Abstract

Echinococcosis is one of the most important zoonosis in Iran. Due to this fact that providing a reliable diagnostic method for detection of this infection in definitive host is a critical prerequirement for the establishment of appropriate control programs in our country, one hundred and sixteen carnivores including 80 dogs, 27 jackals, 8 foxes and one wolf were collected from rural areas of Hamadan, Azarbaijan and Tehran provinces and examined for Echinococcus granulosus infection. Canine echinococcosis was diagnosed upon direct microscopic examination of intestinal contents and mucosal scraping for adult tapeworms, and a coproantigen detection enzyme linked immunosorbent assay (CA-ELISA) for Echinococcus granulosus. The overall prevalence of canine echinococcosis using the ELISA test was 43.1 % (50/116). The relative frequency of canine echinococcosis was 37 % (43/116) by microscopic examination.

The sensitivity and specificity of the CA-ELISA test as referenced by necropsy findings was 72.1 % and 74 % respectively. We found this assay to be a very suitable and advantageous method for the surveillance of canine population especially in regions with endemic echinococcosis.

The epidemiology of swine trichinellosis in China during 1999–2004

Pubblicato online: 01 Mar 2006
Pagine: 21 - 26

Astratto

Abstract

The epidemiology of swine trichinellosis in China during 1999–2004 was reported in this paper. The seroepidemiological survey of swine trichinellosis was carried out by ELISA in 4 Provinces or Autonomous Regions (P/A), the seroprevalence was from 1.63 % to 15.21 %. The prevalence of Trichinella infection in swine slaughtered at abattoirs varied from 0.0001 % to 23 % in 7 P/A. Both of the seroprevalence and prevalence of swine trichinellosis in China has obviously decreased compared with that in 1990’s. The decrease was probably due to a combination of factors, including development of industrialized pig farms, application of commercial grain forages, the improvement of pig production practices and the shortening of swine feeding time. At present, swine trichinellosis in China still is mainly transmitted by garbage (ie. feeding pigs with raw swill). Trichinella infected pigs are predominately from the small farms of suburbs where pigs are fed on swill from the restaurants and from some mountainous areas where pigs are raised outdoors. Pigs were sometimes slaughtered clandestinely at home in rural and mountainous areas without veterinary inspection. The prevalence of Trichinella infection in pork sold at the market was from 0.52 % to 3.66 % in 3 P/A. 17 outbreaks of human trichinellosis, with 828 cases and 11 deaths, were recorded in 8 P/M of China during 2000–2004. Out of 17 outbreaks, 13 (76.47 %) outbreaks were caused by eating raw or poorly cooked pork. Hence, the pig-rearing mode should be changed and all pigs should be raised in piggery, and the mandatory inspection of meat be further strengthen for the control of trichinellosis.

Helminth fauna of sympatric Przewalski’s Equus przewalskii Poljakov, 1881 and domestic horses E. caballus L. in the Chernobyl exclusion zone, Ukraine

Pubblicato online: 01 Mar 2006
Pagine: 27 - 32

Abstract

In 1998 Przewalski’s horses have been introduced in the Chernobyl exclusion zone (CEZ), N Ukraine. They live in the zone under natural conditions. No anthelminthic treatment to these introduced horses has been applied to date. In this same area, 19 domestic horses were also stabled by some peasants. Eighteen years after the Chernobyl nuclear disaster, and five years after this introduction, the diagnostic dehelminthisation method has been applied both to the Przewalski’s horses (n = 21) and the domestic horses (n = 6). In addition, in one Przewalski’s and one domestic horse helmith fauna was surveyed using the post-mortem method. A total of 29 and 19 helminth species has been recorded in the Przewalski’s and domestic horses respectively. Only six helminth species were common for the two horse species compared. Species from the family Strongylidae constituted the dominant helminth group. Four cyathostomine species (Cyathostomum catinatum; Cylicostephanus minutus, C. longibursatus, Cylicocyclus nassatus) formed the majority of helminth parasites both in the Przewalski’s and domestic horses. Our findings suggest that the CEZ has no effect on the species diversity of helminth fauna parasiting Przewalski’s horses, neither it has an effect on the prevalence and intensity of parasite infestation. Behavioural and ecological studies also support the lack of such effect.

Abstract

Of the 105 great cormorants (Phalacrocorax carbo sinensins) from northern Poland (the Vistula Lagoon and Masurian Lake District), examined in 2000–2001, 67 proved hosts of the nematode Syncuaria squamata (Linstow, 1883). The prevalence, mean intensity, and intensity range amounted to 63.8 %, 36.2 specimens, and 1–120 specimens, respectively. The infection was heavier in the immature birds (84.6 %, 40.9 inds, and 1–120 inds) than in the adults (3.7 %, 1 ind.). The nematodes were dominated by gravid females (n=1846), followed by males (n=157), immature females (n=79), and L4 larvae (n=2). Measurements of the parasite are provided. S. squamata is a new species for the parasite fauna of Poland.

Pagine: 37 - 41

Astratto

Abstract

A survey of gastrointestinal helminth communities of Podarcis bocagei and Podarcis carbonelli (Sauria: Lacertidae) from NW Portugal was conducted to determine the prevalence, intensity and diversity of intestinal parasites in these lizards. A few parasite species were found in both hosts, their prevalences, mean intensities and abundances of infection being low or very low. Low values of richness and abundance of parasite species were also found in the helminth infracommunities of individuals of both host species. These low values of parameters of infection and diversity are discussed and compared between both host species and among other Iberian lacertid lizards.

Nematode communities in greenhouse soil of different ages from Shenyang suburb

Pubblicato online: 01 Mar 2006
Pagine: 51 - 55

Astratto

Abstract

The distribution of nematode communities with depth in greenhouse soil of different ages from Shenyang suburb was investigated in October 2004. Thirteen families and 23 genera were observed in our study. Heterocephalobus was dominant genus in all treatments. The numbers of total nematodes and trophic groups declined with soil depth but increased with greenhouse age. Bacterivores were the most abundant trophic group in all treatments, followed by plant parasites and omnivores-predators, while fungivores were the least, only accounted for less than 4 % of the total abundance. Maturity index (MI) and plant parasite index (PPI) were effective in distinguishing differences in nematode community structure in different ages of greenhouses. The numbers of total nematodes were positively correlated with soil organic carbon, total nitrogen, nitrate, and electrolytic conductivity, but negatively with soil pH.

Abstract

A survey of gastrointestinal helminth communities of Podarcis bocagei and Podarcis carbonelli (Sauria: Lacertidae) from NW Portugal was conducted to determine the prevalence, intensity and diversity of intestinal parasites in these lizards. A few parasite species were found in both hosts, their prevalences, mean intensities and abundances of infection being low or very low. Low values of richness and abundance of parasite species were also found in the helminth infracommunities of individuals of both host species. These low values of parameters of infection and diversity are discussed and compared between both host species and among other Iberian lacertid lizards.

Abstract

A nematode survey was carried out in South Moravia and Bohemia (Czech Republic) to assess the occurrence of Xiphinema in the rhizosphere of fruit orchards. Sixty six orchards in South Moravia and seven in Bohemia were studied during the years 2003 and 2004. Four Xiphinema species (X. diversicaudatum, X. pachtaicum, X. simile and X. vuittenezi) were recorded. X. simile constitutes a first record for the nematodes fauna of the Czech Republic.

Nematode communities in greenhouse soil of different ages from Shenyang suburb

Pubblicato online: 01 Mar 2006
Pagine: 51 - 55

Abstract

The distribution of nematode communities with depth in greenhouse soil of different ages from Shenyang suburb was investigated in October 2004. Thirteen families and 23 genera were observed in our study. Heterocephalobus was dominant genus in all treatments. The numbers of total nematodes and trophic groups declined with soil depth but increased with greenhouse age. Bacterivores were the most abundant trophic group in all treatments, followed by plant parasites and omnivores-predators, while fungivores were the least, only accounted for less than 4 % of the total abundance. Maturity index (MI) and plant parasite index (PPI) were effective in distinguishing differences in nematode community structure in different ages of greenhouses. The numbers of total nematodes were positively correlated with soil organic carbon, total nitrogen, nitrate, and electrolytic conductivity, but negatively with soil pH.
