SUMMARYWe studied the component community of lung-worms of the harbour porpoise, attempting to establish the relative importance of ecological and evolutionary factors on its development. The lungs of 64 porpoises by-caught in Norwegian waters were examined for helminths. Three pseudaliid species were detected. The porpoises appear to be readily colonized by lung-worms, the structure of the component community of calves being fairly similar to that of the remainder. Prenatal and/or transmammary infections might partly account for these early infections. However, host age was correlated with th

The infection procedure established 4 non-overlapping levels of infection which persisted until 6 weeks post-infection (p.i.), after which there was an overall decline up to 12 weeks p.i. Worm numbers had no direct effect on adult worm survival but temporal changes in worm weight were density-dependent. Adult worm establishment in the lungs declined significantly as the n

Summary129/Ola mice resemble WEHI 129J mice in that around 70% of the individuals in any given population resist a primary infection withSchistosoma mansoni. Squashed-organ autoradiographic tracking of [Se]selenomethionine-labelled parasites has shown that the kinetics of worm migration in 129/Ola mice follows the expected pattern, and that all rodents harbour essentially similar numbers of worms on day 14 post-infection. Combined lung and liver worm recovery techniques have revealed, however, that segregation of mice into ‘permissive’ and ‘non-permissive’ individuals can first be detected on

Pneumoascariasis is an infestation from one of the most common worms or helminths found on earth in the respiratory system. The worm is called Ascaris lumbricoides, which penetrates and infests the human body through the fecal-oral process. The fertilized Ascaris ova, or simply egg, would develop into larvae, which then move to the liver and lungs through the portal vein system. These larvae will soon develop into mature worms in the human respiratory system, inside the lungs, particularly in the bronchioles. These Ascaris larvae trigger common symptoms such as persistent cough, shortness of b

Abstract: Children and adolescents are most susceptible to the development of tuberculosis, especially when they have concomitant diseases, which lead to a decrease in both humoral and cellular immunity. One of these co-morbidities is helminthiasis. It has been proven that the body’s immune response to worm infestation is reduced, which in turn contributes to the addition of various infections, including tuberculosis. The aim of the study was to study the specifics of the clinical course of primary tuberculosis in children with helminthiasis treated at the Samarkand Regional Center for Tubercu

Following percutaneous infection no difference in initial larval establishment in the lungs was found between male BALB/c, NIH or B10.G mice. However, significant differences in the subsequent kinetics of infection were demonstrated between the BALB/c and NIH strains. Lung worm burdens declined more slowly in NIH mice than in BALB/c strain. Surprisingly, however, a greater proportion of larvae remaining in the lungs of BALB/c mice, 9 days p.i., were trapped than in NIH m

Although clinical trials have not been completed, it has already been confirmed that mebendazole, a well-known anti-parasitic drug widely used in the tropical areas, inhibits cancer cell growth. Preclinical studies show that mebendazole notably impedes the growth of malignant and metastatic tumors such as osteosarcoma and soft tissue sarcoma, melanoma, carcinoma (lung, colorectal, breast, ovarian, hepatocellular and adrenocortical), acute myeloid leukaemia, glioblastoma multiforme and meduloblastoma. Mebendazole can induce the depolymerization of microtubules in neoplasms and newly formed vasc

Brain abscesses caused by Listeria monocytogenes (LM) are very rare and carry a high mortality risk. We present a patient with disseminated non-small cellular lung cancer (NSCLC) and multiple unusual LM brain abscesses. These abscesses have multiple elongated peripherally enhancing lesions in a characteristic formation that is “worm or tramtrack-like” following the white matter fiber tracts.

ABSTRACTThe prophylactic and curative effects of praziquantel and oxamniquine on a Saudi Arabian strain of Schistosoma mansoni in MF-1 mice were assessed. The drugs were administered orally. At 240 mg/kg praziquantel, there was a reduction of 89·1% in adult worm recovery and a marked reduction in tissue deposited eggs. The reduction in adult worm recovery after dosing with 50 mg/kg oxamniquine was 89·2%. At low doses (40 mg/kg praziquantel and 30 mg/kg oxamniquine) administered at 11 days, 5 days and 3 h before and 5, 21 and 49 days after infection, the reduction in adult worm recovery was 0·0

Abstract Th2 cells are essential for protective immunity to helminths but also contribute to chronic inflammation. Here we identify the REsistin-Like Molecules RELMα and Resistin as critical mediators of this balance between helminth Th2-mediated immunity and inflammation in both murine infection and human studies. Following infection with Nippostrongylus brasiliensis, we observed significant macrophage expression of RELMα in the lungs. When RELMα-/- mice were infected with N. brasiliensis, there were increased Th2-type responses, accelerated worm expulsion and exacerbated lung inflammation co

Eight dogs were considered to have a low burden of heartworms and 9 had a high burden. Dogs with a high worm burden had more severe pulmonary thromboembolism with pulmonary hypertens

Hydatidosis is a parasitic infection caused by Echinococcus granulosus (Dog Tape-worm). India is endemic for hydatid disease. The lung is the second most frequently affected organ by hydatid cysts after the liver. Hydatid cysts are mostly seen in the right lower lobe of the lung. We report an unusual presentation of ruptured pulmonary hydatid cyst as empyema and haemothorax in a 24-year-old boy who presented with dyspnoea on exertion with right-sided chest pain. Pleural fluid was suggestive of empyema. The pleural fluid examination revealed plenty of neutrophils and the presence of hooklets of

Background Paraquat (PQ) is an effective and widely used herbicide and causes numerous fatalities by accidental or voluntary ingestion. However, neither the final cytotoxic mechanism nor effective treatments for PQ poisoning have been discovered. Phenotypic drug discovery (PDD), which does not rely on the molecular mechanism of the diseases, is having a renaissance in recent years owing to its potential to address the incompletely understood complexity of diseases. Herein, the C. elegans PDD model was established to pave the way for the future phenotypic discovery of potential agents for treat

Two weeks later the animals were perfused and mature and immature worms counted separately. Statistically significant differences were observed in the recovery of immature worms, when the control group was compared with those twice infected. No statistical difference was detected

AbstractAscariasis is a common helminthic infection, particularly in the tropical countries. We describe a case of eosinophilia who underwent coronary artery bypass graft (CABG) surgery. Postoperatively, he was found to have ascaris lumbricoides in the oral cavity. Timely detection and removal of the worm prevented the possible complications such as airway obstruction, bronchospasm, lung collapse, or intestinal obstruction. The case emphasizes the importance of considering parasitic infection as a differential diagnosis in patients presenting with eosinophilia for elective surgery.

SUMMARYThe complexity of helminth macroparasites is reflected in the intricate network of host cell types that participate in the Type 2 immune response needed to battle these organisms. In this context, adaptive T helper 2 cells and the Type 2 cytokines interleukin (IL)-4, IL-5, IL-9 and IL-13 have been the focus of research for years, but recent work has demonstrated that the innate immune system plays an essential role. Some innate immune cells that promote Type 2 immunity are relatively abundant, such as macrophages and eosinophils. However, we now appreciate that more rare cell types incl
