Moreover, 107 specimens, including vaginal swabs, organ tissues and milk were analysed by Polymerase Chain Reaction (...

Antennae are among the most elaborate sensory organs in adult flies, and they provide rich information for phylogenic studies. The antennae of five out of eight species of Gasterophilus Leach (G. haemorrhoidalis (Linnaeus), G. intestinalis (De Geer), G. nasalis (Linnaeus), G. nigricornis (Loew) and G. pecorum (Fabricius)), were examined using scanning electron microscopy. The general morphology...

With interest we read the article of Saito et al. that describes a severe case of chlamydiosis in humans (3). However, according to us two major points need to be clarified. The taxonomy of chlamydiae has been illustrated in 1999 by Everett et al. (1), and such classification is accepted universally, as evidenced by a number of manuscripts published in recent years. Classification is based on d...
