Developmental surface ultrastructure of Macroorchis spinulosus in albino rats.

Recovery, growth and development of Macroorchis spinulosus in albino rats.

The developmental features, growth and organogenesis of Macroorchis spinulosus were observed in albino rats. Globular and thick walled metacercariae, possessed a stylet, Y-shaped excretory bladder and extracecal testes. In albino rats, M. spinulosus showed habitat shifting. The majority of M. spinulosus reside in the jejunum for the first four days post infection (p.i.) and migrate to the duode...

Molecular Description of Macroorchis spinulosus (Digenea: Nanophyetidae) Based on ITS1 Sequences.

We performed a molecular genetic study on the sequences of 18S ribosomal RNA (ITS1 region) gene in 4-day-old adult worms of Macroorchis spinulosus recovered in mice experimentally infected with metacercariae from crayfish in Jeollanam-do Province, Korea. The metacercariae were round, 180 μm in average diameter, encysted with 2 layers of thick walls, but the stylet on the oral sucker was not cle...

Histopathological Effects of Titanium Dioxide Nanoparticles and The Possible Protective Role of N-Acetylcysteine on The Testes of Male Albino Rats

Objective Titanium dioxide (TiO2) is a white pigment which is used in paints, plastics, etc. It is reported to induce ‎oxidative stress and DNA damage. The N-acetylcysteine (NAC) was used to fight oxidative stress-induced ‎damage in various tissues. The aim of this study was to evaluate the toxic effects of TiO2 nanoparticles by oral ‎administration and the protective role of NAC on testes of a...

The Transmission of the Virus of Mexican Typhus from Rat to Rat by Polyplax Spinulosus

Polyplax spinulosus, the common rat louse, is easily infected with the virus of typhus by feeding on infected rats. As in the case of Pediculus humanus, such feedings are followed by the appearance of large numbers of Rickettsia prowazeki within the gut of the insect. The virus of Mexican typhus can be transmitted from rat to rat by Polyplax spinulosus by methods of feeding simulating natural c...
