A case of gastric pseudoterranoviasis in a 43-year-old man in Korea. (1/38)

A case of Pseudoterranova decipiens infection was found in a 43-year-old man by gastroendoscopic examination on August 20, 1996. On August 6, 1996, he visited a local clinic, complaining of epigastric pain two days after eating raw marine fishes. Although the symptoms were relieved soon, endoscopic examination was done for differential diagnosis. A white, live nematode larva was removed from the fundus of the stomach. The larva was 38.3 x 1.0 mm in size and had a cecum reaching to the mid-level of the ventriculus. A lot of transverse striations were regularly arranged on the cuticle of its body surface, but the boring tooth and mucron were not observed at both ends of the worm. The worm was identified as the 4th stage larva of P. decipiens.  (+info)

Plasma and bile antibodies of the teleost Trematomus bernacchii specific for the nematode Pseudoterranova decipiens. (2/38)

We investigated the occurrence of antibodies against protein antigens of the nematode parasite Pseudoterranova decipiens in the plasma and bile of the Antarctic teleost Trematomus bernacchii. Three different P. decipiens protein solutions were prepared: excreted/secreted proteins from live larvae (ESP); surface-associated proteins obtained by mild extraction of larval bodies (SAP); and cuticular soluble proteins recovered by extraction in strong reducing conditions (CSP). Using different immunoassays, these 3 preparations were tested for their ability to bind fish antibody. As determined by ELISA, the specific antibody binding activity was higher in SAP than in CSP. As determined by dot-blot immunoassay, the specific antigen binding activity versus SAP was higher in bile than in plasma antibodies. A different number of antigenic components of SAP and ESP were identified by immunoblotting performed with plasma or bile antibodies. These results led to the conclusion that T. bernacchii parasitism by nematodes involves plasma and bile anti-parasite antibodies. Furthermore bile antibodies were found to be more reactive and more heterogeneous than plasma.  (+info)

Larvae of Contracaecum sp. among inshore fish species of southwestern Australia. (3/38)

Larval nematode infections were investigated in 236 fish from 17 estuarine and near-shore species in southwestern Australia. Larvae of the genus Contracaecum were found in 4 species of fish (Acanthopagrus butcheri, Sillaginodes punctata, Mugil cephalus and Aldrichetta forsteri). The prevalence and intensity of infection was highest in the 2 species of mullet: 81% infected and 9.8 +/- 1.5 larvae fish(-1) for M. cephalus; 100% and 12.7 +/- 3.7 larvae fish(-1) for A. forsteri. There was no evidence of post-mortem migration of worms from the visceral organs to the musculature of the fish.  (+info)

Experimental heteroxenous cycle of Lagochilascaris minor Leiper, 1909 (Nematoda: Ascarididae) in white mice and in cats. (4/38)

Reports of natural infections of sylvatic carnivores by adult worms of species similar to Lagochilascaris minor in the Neotropical region led to attempts to establish experimental cycles in laboratory mice and in cats. Also, larval development was seen in the skeletal muscle of an agouti (Dasyprocta leporina) infected per os with incubated eggs of the parasite obtained from a human case. In cats, adult worms develop and fertile eggs are expelled in the feces; in mice, larval stages of the parasite develop, and are encapsulate in the skeletal muscle, and in the adipose and subcutaneous connective tissue. From our observations, we conclude that the larva infective for the mouse is the early 3rd stage, while for the final host the infective form is the later 3rd stage. A single moult was seen in the mouse, giving rise to a small population of 4th stage larvae, long after the initial infection.  (+info)

Raccoon roundworm eggs near homes and risk for larva migrans disease, California communities. (5/38)

The raccoon roundworm, Baylisascaris procyonis, is increasingly recognized as a cause of serious or fatal larva migrans disease in humans and animals. We assessed the potential for infection in three northern California communities by determining the density and distribution of raccoon latrines, where transmission primarily occurs, and the prevalence of eggs at private residences. We collected fecal samples from 215 latrines and found that 44%-53% of the latrines contained B. procyonis eggs and that 16%-32% contained infective eggs. Among the properties surveyed, 28%-49% harbored at least one latrine that was positive for B. procyonis eggs. The latrine densities in these communities were higher than any previously reported. The presence of B. procyonis eggs in raccoon latrines was common, widespread, and closely associated with human habitation. Where raccoon densities are high, education of the public and removal of raccoons may be necessary.  (+info)

A new nematode species Goezia leporini n. sp. (Anisakidae) from cultured freshwater fish Leporinus macrocephalus (Anostomidae) in Brazil. (6/38)

This paper describes nematode infection in the cultured freshwater fish Leporinus macrocephalus (Osteichthyses: Anostomidae) collected at Batatais, Sao Paulo State, Brazil. Of a total of 32 examined fish, 21 (65%) were infected with Goezia leporini n. sp. (Nematoda: Anisakidae) with mean infection intensity of 4.1 parasites. The nematodes presented total length greater than G intermedia, G. holmesi, G. pelagia, G. minuta, G. kliksi, G. sinamora, G. nonipapillata, G. alii, G. moraveci, G. brasiliensis, and G. brevicaeca. The main difference was a great number of preanal papillae in males when compared to G. brasiliensis and G. brevicaeca. The present description also differs from that of G. brasiliensis with respect to spicule length and distance of vulva from the anterior extremity.  (+info)

Gastrointestinal impaction by Parascaris equorum in a Thoroughbred foal in Jeju, Korea. (7/38)

A weanling Thoroughbred foal was admitted to Equine Hospital, Korea Racing Association with signs of colic. On admission the foal was sweating profusely, appeared anxious and exhibiting signs suggestive of abdominal pain. Clinical examination revealed: tachycardia (90 beats/min), tachypnea (50 breaths/min) and congested and slightly cyanotic mucous membranes. No intestinal sounds were auscultated in all 4 abdominal quadrants. Rectal palpation identified concurrent cecum and large colon impactions. Treatment consisted of intravenous administration of a balanced electrolyte solution, nasogastric siphonage and administration of analgesics. Nasogastric reflux contained ascarids. This treatment failed to alleviate the signs of colic. The foal died 3 hours later following discharge because the owner didn't want laparatomy because of economic constraints. Prior to admission this foal had not received any prophylactic anthelmintic treatment. In necropsy, there were masses of ascarids accumulation in the stomach, small intestine and large intestine. The outcome of this report is to describe the first diagnosed case of gastrointestinal impaction by P. equorum in a Thoroughbred foal in South Korea and indicates the importance of regular anthelmintic treatment.  (+info)

Baylisascariasis. (8/38)

The raccoon roundworm, Baylisascaris procyonis, is the most common and widespread cause of clinical larva migrans in animals. In addition, it is increasingly recognized as a cause of devastating or fatal neural larva migrans in infants and young children and ocular larva migrans in adults. Humans become infected by accidentally ingesting infective B. procyonis eggs from raccoon latrines or articles contaminated with their feces. Two features distinguish B. procyonis from other helminthes that cause larva migrans: (i) its aggressive somatic migration and invasion of the central nervous system and (ii) the continued growth of larvae to a large size within the central nervous system. Typically, B. procyonis neural larva migrans presents as acute fulminant eosinophilic meningoencephalitis. Once invasion of the central nervous system has occurred, the prognosis is grave with or without treatment. To date, despite anthelmintic treatment of cases of B. procyonis neural larva migrans, there are no documented neurologically intact survivors. Epidemiologic study of human cases of neural larva migrans demonstrate that contact with raccoon feces or an environment contaminated by infective eggs and geophagia or pica are the most important risk factors for infection. In many regions of the United States, increasingly large populations of raccoons, with high rates of B. procyonis infection, live in close proximity to humans. Although documented cases of human baylisascariasis remain relatively uncommon, widespread contamination of the domestic environment by infected raccoons suggests that the risk of exposure and human infection is probably substantial. In the absence of early diagnosis or effective treatment, prevention of infection is the most important public health measure.  (+info)

  • Impact of protein energy malnutrition on Trichuris suis infection in pigs concomitantly infected with Ascaris suum. (
  • The same naming convention applies to all helminths whereby the ending "-asis" (or in veterinary science the ending "-osis") at the end of the name of the worm is added to signify the infection with that particular worm, for example Ascaris is the name of a particular helminth, and ascariasis is the name of the infectious disease caused by this helminth. (
  • This is the most common tapeworm infection in the world and can be transmitted between humans. (
  • Infection of humans by this parasite and the ensuing disorders are referred to as baylisascaris , and can affect other small mammals as well . (
  • Consumption of eggs from feces-contaminated items is the most common method of infection for humans especially children and young adults under the age of 20 years. (
  • This is a mostly food-borne infection caused by the lung fluke Paragonimus westermani, however, domesticated animals may also harbor the fluke and transmit the disease to humans. (
  • Infection with T. gondii is probably the leading cause of posterior uveitis in humans and the most comment route of transmission is raw and undercooked meat from infected animals. (
  • Therefore, we performed a cross-sectional pilot study and estimated the seroprevalence of Toxocara infection in humans in Shandong Province, eastern China for the first time, from June 2011 to July 2013, involving clinically healthy individuals, pregnant women and psychiatric patients, aiming to attract public attention to Toxocara infection. (
  • After this time, any organism (from worms and rodents to humans) that ingests these eggs is at risk of infection. (
  • [ 1 ] [ 3 ] Epidemiological studies indicate a worldwide distribution of Trichostrongylus infections in humans, with the highest prevalence rates observed in individuals from regions with poor sanitary conditions, in rural areas, or who are farmers / herders. (
  • The major clinical manifestations of B. procyonis include visceral larva migrans (VLM), neural larva migrans, (NLM) and ocular larva migrans (OLM), which fall under the broader description of infection with B. procyonis , termed Baylisascaris . (
  • This may be beneficial in definitively diagnosing infection with Baylisascaris procyonis , which may otherwise be difficult . (
  • Ascaridida Infections" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings) . (
  • Even while being treated for certain tapeworm infections, reinfection can result from ingesting tapeworm eggs shed by the adult worm into the stool, as a result of insufficient personal hygiene. (
  • Although it is relatively easy to diagnose a roundworm-infected animal as having a parasitic worm (helminth) infection of some type, it is significantly more difficult to identify roundworm, specifically, as the causative worm. (
  • The prevention and control of lung worm infection can be achieved most effectively by integration of three interrelated approaches: administration of effective Anthelmentic drugs, immunization and improved management practices. (
  • The pinworm has a worldwide distribution, [ 14 ] and is the most common helminth (i.e., parasitic worm) infection in the United States, western Europe, and Oceania. (
  • In the current study in which longer lag periods for challenge infection after the second immunization were used, worm burden reductions compared to adjuvant controls were a significant 43% and 76%, respectively. (
  • Hence, it is a very rare infection in developed economies and is less prevalent in urban areas in developing countries than in rural areas, where sanitation standards are poor. (
  • The variability of the unregulated and unstable epizootic events of diphyllobothriidean cestodes presents a challenge to understand the ecological and evolutionary factors influencing the prevalence of infections in host populations. (
  • Confirmation of the presence or absence of roundworm, whipworm and/or hookworm in the mammal may be made, for example, for the purpose of selecting an optimal course of treating the mammal and/or for the purpose of determining whether the mammal has been rid of the infection after treatment has been initiated. (
  • Intestinal roundworm infection is common in animals and, if left untreated, can cause serious disease and even death. (
  • This is a problem because roundworm infections are best treated when the infected animal's caregiver has knowledge that roundworm is the specific source of the infection. (
  • Current methods for diagnosis of roundworm infections primarily involve microscopic examination of fecal samples, either directly in fecal smears or following concentration of ova by flotation in density media. (
  • In recent years, however, there have been advances in the diagnosis of Oesophagostomum infection with PCR assays and ultrasound and recent interventions involving mass treatment with albendazole shows promise for controlling and possibly eliminating Oesophagostomum infection in northern Togo and Ghana. (
  • The intensities of infection by P. lutzi and O. chabaudi were different among male and female hosts, with males also exhibiting the highest values. (
  • Depending on the severity of infection, age and immunological status of the animal, the clinical sign ranges from moderate coughing with slightly increased respiratory rates to sever persistent coughing, persistent respiratory distress and failure. (
  • Although P. rufescens infection is widespread, it does not usually cause major clinical disease. (
  • To determine if infection induces a similar functional change in the placenta, immunohistochemistry for antibodies to cleaved caspase-3 (activated caspase-3) and the (TDT)-mediated dUTP-digoxigenin nick end labeling (TUNEL) technique were used to compare the amount of placental apoptosis in infected and noninfected placentas. (
  • Comparison of the present data with the results of studies performed in the North Pacific in the 1960s, showed a significant decrease in the intensity of NFS infection with anisakids during the last decades. (
