Abstract
BACKGROUND The aim of this study was to determine a parasitic species composition, prevalence and intensity of infection in selected parrots. MATERIAL AND METHODS The studies were carried out on faecal samples of budgerigars Melopsittacus undulatus (n = 36), cockatiels Nymphicus hollandicus (n = 21), grey parrots Psittacus erithacus (n = 18), eastern rosella Platycercus eximius (n = 10) and senegal parrots Poicephalus senegalus (n = 10) using the Willis-Schlaff and McMaster's methods. RESULTS Protozoans (Isosporidae and Eimeriidae) and nematodes (Ascarididae, Capillaridae and Heterakidae) were detected in the tested samples. Coccidian oocysts were detected in all examined parrots. Isospora and Eimeria oocysts were found in 52.9% Melopsittacus undulatus, 60% Poicephalus senegalus and 66.7% Psittacus erithacus. Mean number of oocysts per gram of feces (OPG) was high: from about 270 to 1500 depending on both parasite and host species. Three species of parrots were infected with the nematodes (Nymphicus hollandicus and Poicephalus senegalus were free from this infection), but only Ascaridia platycerci was present in these hosts, with the highest prevalence (20%) and highest mean number of eggs per gram of feces (EPG = 1242) in Platycercus eximinus. Heterakis gallinarum was observed only in Psittacus erithacus; 16.6% individuals were infected, and EPG was 212. The highest intensity of infection with nematodes of Ascarididae and Capillaridae was in Platycercus eximius. EPG in this species of parrots was 1242 and 2480, respectively. The obtained results show that introduction of parasitological prophylaxis programs is necessary, especially in the larger birds' farmings and zoological shops.

Abstract
Nematode parasite infections of semi-domestic reindeer grazing in their natural habitat in northern Finland were monitored for approximately 2 years. This was achieved by monthly faecal egg counts of male and female calves and adult females from an experimental reindeer herd, in addition to estimating the acquisition of nematode infection from pasture using tracer reindeer calves. The most abundant parasite was Ostertagia gruehneri in the worm counts of tracer animals and in faecal egg counts of adult female reindeer. Capillaria sp. eggs were detected in calves and adults, but Nematodirinae eggs were only recovered from calves. Faecal egg counts showed variations between months for each nematode species, with male and female calves shedding similar numbers of eggs. During each year, calves shed more Capillaria sp. eggs than adult female reindeer, but similar numbers of O. gruehneri eggs. Egg counts of O. gruehneri were more abundant in late summer-autumn (July-September), whereas Capillaria sp. and the Nematodirinae dominated the winter months (November-February). The seasonal trends of adult worm burdens of O. gruehneri in the tracers paralleled the egg count patterns. Capillaria sp. was not detected in tracer worm counts. Tracer worm burdens showed that the proportion of inhibited larvae of O. gruehneri and Nematodirinae steadily increased from spring to early winter, followed by a decline and a commensurate increase in the number of adult parasites in the second summer. This investigation showed that parasite transmission occurs continuously throughout the year for nematode parasites of reindeer in northern Finland.

Abstract
A survey of the parasitic fauna of the Norwegian red fox (Vulpes vulpes) population was carried out in 1994/1995 and 2002-2005. All foxes were killed during the licensed hunting season from October to April and, in total, 393 animals from all regions of the country were examined. The present study details the results of extra-intestinal nematode and Trichinella larvae examinations. All individuals were examined for Trichinella, using routine digestion methods. Parasitological examination of the internal organs of some of the foxes also identified a number of different extra-intestinal nematodes. The following prevalences were identified (number positive/number foxes examined): Trichinella larvae 19/393 (4.8%); Capillaria böhmi (C. böhmi) 88/174 (51%); Capillaria aerophila (C. aerophila) 160/181 (88%); Crenosoma vulpis (Cr. vulpis) 105/181 (58%) and Capillaria plica (C. plica) 81/154 (53%). No evidence of Angiostrongylus vasorum infection was found. The 19 different Trichinella isolates were species typed by PCR and sequence analysis; 18 isolates were identified as Trichinella nativa and one as Trichinella britovi. A wide geographical distribution of the parasites was seen. The following exceptions were recorded: C. böhmi, the prevalence of which was significantly lower in northern Norway (6%) compared to other regions (central Norway, eastern Norway and southern and western Norway; 52-57%). There was a significantly higher prevalence of Trichinella infection in eastern Norway (8.1%), when compared with the rest of the country (0.6%). Cr. vulpis prevalence was significantly higher in central Norway (83%) than in other regions (41-56%). There were no significant differences in age and sex distribution of the parasites with the exception of Cr. vulpis where juvenile foxes had a greater likelihood of infection. The data also indicated that adult foxes were more commonly infected with Trichinella larvae (5.8%) than juveniles (3.3%) (no statistical significance).

Abstract
A new species, Pterothominx (Pterothominx) moraveci n. sp. (Trichinelloidea: Capillariidae) is described from an Australian parrot, Barnardius zonarius Shaw (Psittacidae: Psittaciformes), imported from Germany and kept in captivity in the Czech Republic. Males of the new taxon differ from all other species of the subgenus Pterothominx Freitas, 1959, which mainly parasitise galliform birds, in having a shorter spicule (0.925-1.338; mean 1.050 mm), a shorter body length and a different form of armed spicular sheath and bursa. Females differ in having the smallest eggs (40-50 x 20-25; mean 48 x 23 microm) and in other morphometrical characters. From the species P. (P.) totani (Linstow, 1875), which parasitises charadriiform birds, the new species differs in its smaller number of stichocytes (females 42-46, mean 44; versus 50-54), different form of the bursa and praebursal alae, and other characters. This is the only species of Pterothominx that parasitises psittacine birds.

Abstract
We trapped 664 rodents belonging to five non-commensal species in the canton of Geneva, Switzerland, and found a significant cluster of Capillaria hepatica infections in three species in rural and urbanized areas of the northern part of the canton. C. hepatica infections were discovered in the yellow-necked mouse Apodemus flavicollis (n=99) with an overall prevalence (OP) of 7.0% and a clustered prevalence (CP) of 20%, in the bank vole Clethrionomys glareolus (n=58, OP 5.2%; CP 19%), and in the water vole Arvicola terrestris scherman (n=466; OP 0.2%; CP 4%). The estimated numbers of C. hepatica eggs isolated from infected livers ranged from 1,914 to 938,000 per animal.

Abstract
We report the first case of hepatic capillariasis in Maine. The patient was a 54-year-old male carpenter who presented with a subacute history of severe abdominal pain, fevers, and weight loss. Initial diagnostic studies suggested a hepatic mass associated with para-aortic lymphadenopathy. The patient underwent open laparotomy for resection of the mass. He was found to have an eosinophilic granuloma in the liver; further evaluation revealed degenerating Capillaria hepatica. The exact route of infection in this case is unknown but is most likely due to accidental ingestion of soil contaminated with mature capillaria eggs. This patient had a low parasite burden and did not exhibit significant peripheral eosinophilia. After treatment with thiabendazole, he recovered uneventfully.

Abstract
Among meat inspectors in Hokkaido, Japan, the term "bovine parasitic hepatitis" (BPH) has long been used to refer to a hepatic disorder characterized by multiple small yellowish lesions. However, the aetiology is unknown. By means of detailed histopathological examination, fragments of parasitic worms resembling Capillaria were detected in nine (2.25%) of 400 livers showing BPH lesions. Histologically, the degenerative lesions showed eosinophilic papillary endothelial hyperplasia of the interlobular veins and eosinophilic membranous structures in the eosinophilic granulomatous areas of inflammation. These characteristic findings differed from those of hepatic capillariasis of other animal species. BPH was found in 5-20% of milk cows examined throughout Hokkaido, and was also detected in cattle from another prefecture and from Australia. Possibly the same parasitic disorder, albeit undiagnosed, is more widespread.

Abstract
Human intestinal capillariasis is a rare parasitosis that was first recognized in the Philippines in the 1960 s. Parasitosis is a life threatening disease and has been reported from Thailand, Japan, South of Taiwan (Kaoh-Siung), Korea, Iran, Egypt, Italy and Spain. Its clinical symptoms are characterized by chronic diarrhea, abdominal pain, borborygmus, marked weight loss, protein and electrolyte loss and cachexia. Capillariasis may be fatal if early treatment is not given. We reported 14 cases living in rural areas of Taiwan. Three cases had histories of travelling to Thailand. They might have been infected in Thailand while stayed there. Two cases had the diet of raw freshwater fish before. Three cases received emergency laparotomy due to peritonitis and two cases were found of enteritis cystica profunda. According to the route of transmission, freshwater and brackish-water fish may act as the intermediate host of the parasite. The most simple and convenient method of diagnosing capillariasis is stool examination. Two cases were diagnosed by histology. Mebendazole or albendezole 200 mg orally twice a day for 20-30 d is the treatment of choice. All the patients were cured, and relapses were not observed within 12 mo.

Abstract
Capillaria philippinensis is an emerging infection in Egypt. Reports in children are scarce. We report here two sisters with C. philippinensis infection, aged 8 and 12 years. Their father was a fisherman and they had a habit of picking small pieces of uncooked fish to eat while their mother prepared their meals. They came from El-Menia governorate, which lies in the northern part of Upper Egypt. Most reported cases from Egypt come from this governorate and nearby areas. Both sisters had persistent profuse watery diarrhea of 12 months' duration. Their weights were below the 5th percentile for age. Both were hypoalbuminemic, but only the younger had pedal edema. Both had hypokalemia and hyponatremia. During the course of their illness they were repeatedly admitted to different hospitals and received intravenous fluids, but the correct diagnosis was not reached. Diagnosis was made by stool examination at our hospital when eggs and larvae were detected in stool samples. Although a diagnosis was promptly made, the older sister who suffered from pneumonia and septic shock unfortunately died a few days after admission. The younger sister was treated successfully with albendazole 200 mg twice daily. Diarrhea abated, pedal edema disappeared, and she started to gain weight.

Abstract
Calodium hepaticum (syn. Capillaria hepatica), a nematode parasite commonly found in the liver of wild rodents, infects a wide variety of mammals, including humans. A retrospective study of black-tailed prairie dogs (Cynomys ludovicianus) at the Baltimore Zoo showed that 5 of 21 (24%) of the prairie dogs submitted for postmortem examination between 1981 and 2001 had hepatic capillariasis, with all the infections diagnosed during or after 1997. Affected livers contained multifocal granulomas containing numerous eggs and occasional adult nematodes. Asymptomatic wild rats in the zoo with a high prevalence of infection may have served as a reservoir for the disease. Wild rodent control is essential to minimize exposure of susceptible exhibition animals as well as humans to C. hepaticum.

Abstract
During an excavation of a site of the corded ware culture in the Saale-Unstrut-Valley (ca. 3000 BC) in Germany, a soil sample from the pelvis of a human skeleton was studied under palaeoparasitological aspects. Eggs of the trematode Fasciola hepatica and of the nematode genus Capillaria were found. This is the first case of a direct association of a F. hepatica-infestation to both a prehistoric human skeleton and domesticated animal remains. Sheep and cattle bones were present at the same site and F. hepatica eggs were found in bovine samples. This strongly points toward an existing infection cycle, involving humans as a final host.

Abstract
Seven new cases of intestinal capillariasis were detected in Kasr El-Aini University Hospitals, Cairo, during the period from July 1997 to June 1998. A parasitological study concerning the morphological features of Capillaria philippinensis recovered from the stool of Egyptian cases was carried out. Eggs were separated, cultured and used to infect Oreochromis nilotica niloticus, a famous popularly consumed type of fresh water fish in Egypt in a trial for identification of the fish intermediate host for this parasite, but infection had not developed in the intestine of this species of fish.

Abstract
The first finding of a Capillariid in the urinary tract of a free ranging maned wolf (Chrysocyon brachyurus) is described. The individual was an adult male attacked by dogs in the locality of Cayastacito (Santa Fe, Argentina, 31 degrees 05' S, 60 degrees 34' W). Eggs found in urine measured 64.6-66.9 micrometer (mean 65.4 micrometer) x 26.9-31 micrometer (mean 29 micrometer). Further studies are needed to determine whether this finding corresponds to a new Capillariid species, related to C. brachyurus, or it is an already described species that has been introduced by domestic dogs.

Abstract
Intestinal capillariasis has been reported in Egypt in 1989. Since that time, 44 cases have been diagnosed. Most of the detected cases were females (37), while males were only 7. Their ages ranged from 10 to 65 years, however most of them were between 20 to 40 years. Twenty-six cases were from the northern part of Upper Egypt, particularly Bani-Suif and El-Menia Governorates. Patients presented with borborygmi, chronic diarrhea, vomiting, loss of weight, lower limb edema and electrolyte imbalance for durations ranging from one month to two years. Morbidity and mortality of the disease in Egyptian cases are described. Some patients gave history of eating raw whole fish, while others gave history of eating raw parts of fish or half-cooked fish. Diagnosis was based on the clinical picture, and confirmed stool analysis. Differential diagnosis was discussed and the cost paid by patients to reach the correct diagnosis was estimated. Suggestions about the way with which the parasite was introduced and maintained in Egypt were mentioned.

Abstract
Two species of the genus Baruscapillaria Moravec, 1982 are known to parasitise the small intestine of the common cormorant, Phalacrocorax carbo (L.): Baruscapillaria carbonis (Dubinin et Dubinina, 1940) and B. rudolphii Moravec, Scholz et Nasincová, 1994. A redescription of the former species, based on specimens collected from common cormorants shot in South Bohemia, Czech Republic, is provided. Morphological features distinguishing B. carbonis and B. rudolphii are specified. B. carbonis is characterised mainly by the well-developed membranous bursa in the male, composed of five distinct lobes (four lateral and one spur-shaped dorsal); the length of the spicule is 1.9-2.3 mm; gravid females are provided with a long vulvar appendage. Males of B. rudolphii have reduced, bi-lobed membranous bursa and the spicule is 0.9-1.3 mm long; the vulvar appendage is absent in gravid females. This is the first record of B. carbon is in the Czech Republic.

Abstract
Intestinal washes, faecal flotations and serological examinations for antibodies to Toxoplasma gondii and Neospora caninum were used to assess the prevalence of parasites in carcases of foxes killed on roads or shot in the Dublin area and surrounding counties. The ascarids Uncinaria stenocephala and Toxocara canis were prevalent, as was the trematode Alaria alata. Taenia species, eggs of Capillaria species and sporocysts of Sarcocystis species were also found. Only one fox out of 70 examined was seropositive for N. caninum, whereas 24 of 51 were seropositive for T. gondii.

Abstract
Forty-seven wild brown rats (Rattus norvegicus) collected from the urban area of Milan (Italy) were screened for Capillaria hepatica liver infection. The liver of each rat was grossly and histologically examined for the presence of C. hepatica adults, eggs and typical C. hepatica induced lesions. In 17 rats (36%) liver lesions consistent with C. hepatica infection were detected. Grossly, white-yellow nodules of 1-5 mm in diameter were present, either scattered on the liver surface or localized in a single lobe. Histologically, granulomatous liver lesions associated with eggs and/or worms were observed. The degree of gross liver involvement was moderate in most of the positive cases (71%). About 30 cases of C. hepatica infection in humans have been documented world-wide, most of which are reported in children from 1 to 5 years of age. Our results suggest that the potential transmission of C. hepatica to children in the study area should be considered an important health issue.

Abstract
Tissues of 53 adult porcupines (Erethizon dorsatum) from Pennsylvania were obtained for histopathologic examination. Hepatic capillariasis was recorded in 9% of the porcupines. An additional 11% of the liver sections showed lesions that were compatible with migration by Capillaria hepatica. Because only 1 section of the liver per animal was examined microscopically, the documented prevalence of C. hepatica in Pennsylvania is considered conservatively low. However, this condition was subclinical, because none of the infected animals showed clinical signs, and none revealed severe pathologic changes in the affected livers. This seems to be the only report of C. hepatica in porcupines.

Abstract
A 20 year old female from Compostela Valley Province in the Philippines, presenting with chronic diarrhea, borborygmi, bipedal edema, anorexia and weight loss was seen at Davao Regional Hospital. Her stool specimen, suspected by a local medical technologist to have Capillaria philippinensis ova, was forwarded to the Diagnostic Parasitology Laboratory of the College of Public Health, University of the Philippines Manila. It was examined and found to contain Capillaria philippinensis adults, larvae and eggs. Twelve deaths among people coming from the same barangay, affected by a similar illness with no definite diagnosis except "gastroenteritis" were also reported. These prompted health officials to send a team that would investigate the etiology of the disease outbreak labeled as a "Mystery Disease". Seventy-two stool samples from symptomatic patients were examined. Fifty-three (73.6%) individuals were proven to harbor at least one parasite with 16 (22.2%) individuals positive for Capillaria philippinensis infection. Ocular inspection, interviews and focus group discussions revealed that the people's eating habits are not much different from the habits of those from the Ilocos provinces where capillariasis was initially described. In both areas, people are fond of eating kinilaw or raw fish. They also eat raw shrimps, crabs and snails. Furthermore, the people defecate in the field or in the same body of water where they get the fishes, shrimps, crabs and snails that they eat, thus completing the life cycle of Capillaria philippinensis. Fish-eating birds were likely to have spread this parasite to the area. This is the first report of a capillariasis outbreak in Compostela Valley Province, and this should alert health authorities to consider embarking on serious efforts for developing proficiency of laboratory and clinical diagnosis especially in government health facilities where the poor and marginalized sectors of society are likely to consult.
