BACKGROUND Although many experimental studies provide convincing evidence that type II immunity is protective against helminths, recent data in mice demonstrate that Th1 is also important in some cestodes like Hymenolepis nana. OBJECTIVES To identify the role of Th1 and Th2 lymphocytes in immunity against H. nana, the levels of IL-12, IFNgamma, IL-5, and IL-13 were determined in serum of huma...

International Journal of Dermatology 2004, 43 , 357–359 357 A 56-year-old man presented with a recurrent cutaneous eruption of the trunk, associated with itching, which had lasted for several months. Antihistamines, such as cetirizine, loratadine, and fexofenadine, and topical steroids had been used with only temporary relief. Recently, the cutaneous manifestations had become continuous and ver...

Mice of various strain were given orally eggs of Hymenolepis nana maintained by ddY mice and sacrificed for the adult wormrecovery 2 weeks after the administration of the eggs. The mice of ddY, ICR, C3H and BALB/C were highly susceptible to the eggs while those of DBA/2 and C57BL/6 were less susceptible. key words: Hymenolepis nana, mouse, infectivity Mice-Hymenolepis nana model is useful for t...

the water extract of trigonella foenum graecum stem and leaves was tested for lethal activity against hymenolepis nana, syphacia obvelata, and moniezia expansa. the plant extract demonstrated good anthelmintic activity in vitro which is directly related to the concentration of the extract used. the extract also prevents the formation of ascaris larvae from the eggs of ascaris lumbrico- ides (hu...

In the current study, Mitochondrial Cytochrome c oxidase gene especially codons within subunit 1 (cox1) of H. diminuta and H. nana Egyptian isolates from two stages (adult worms and eggs) and hosts origin (human and rat) were amplified, sequenced and aligned. PCR products were approximately 700 bp, 702 bp and 715 bp of H. nana rat isolates, H. diminuta rat isolates, and H. nana human isolates, ...

INTRODUCTION This study evaluated the presence of pathogenic human parasites on field-grown strawberries in the Federal District of Brazil. METHODS A total of 48 samples of strawberries and 48 soil samples from 16 properties were analyzed. RESULTS Contaminated strawberries were detected in 56% of the properties. Schistosoma mansoni, Ascaris lumbricoides or Ascaris suum, Balantidium coli, En...

Background: Although many experimental studies provide convincing evidence that type II immunity is protective against helminths, recent data in mice demonstrate that Th1 is also impor-tant in some cestodes like Hymenolepis nana. Objective: To identify the role of Th1 and Th2 lymphocytes in immunity against H. nana, the levels of IL-12, IFNγ, IL-5, and IL-13 were de-termined in serum of humans ...

BACKGROUND The aim of this study was to determine intestinal and liver helminth infections in Rattus rodents in Tehran Iran. METHODS Overall, 306 traps were put in 39 different regions in Tehran from 2009 to 2010. Rodents, including R. rattus and R. norvegicus were caught by live-traps. They become unconscious and the spinal cords were cut, afterwards the body was dissected and the stomach, s...
