microcerotermes diversus silvestri is the most economically destructive termite in structures in ahvaz (iran), and it consumes almost anything containing cellulose. this species lives in subterranean nests and gains access to buildings and vegetation by constructing underground galleries. because of their insecticidal activity, boron compounds may be beneficial for treating soil to create insec...

microcerotermes diversus (silvestri) is a major pest of buildings and a wide variety of crops and trees in khouzestan province, because of consuming on materials containing cellulose. one new environmentally safe tactic for the control of subterranean termites is baiting world-wide. in laboratory bioassays, toxicity of imidacloprid bait at concentrations of 25, 50 and 100 ppm, was evaluated und...

Citrobacter diversus is a cause of devastating neonatal meningitis, with illness characterized by formation of multiple brain abscesses. We developed an infant mouse intracranial inoculation model to evaluate the pathophysiology of C. diversus neonatal infections. Eighteen of 26 strains inoculated intracranially at a dose of ca. 3.3 x 10(3) CFU caused greater than 50% mortality in 2-day-old mic...

The emergence of strains of Schistosoma resistant to praziquantel has drawn attention to the search for new schistosomacide drugs. Imidazolidinic derivatives have performed outstandingly against adult S. mansoni worms when evaluated in vitro. The molecular modification of imidazolidine by way of bioisosteric replacement gives rise to variations in its biological response. This study verifies th...

Meningitis caused by gram-negative enteric bacteria usually is limited in children to the neonatal period. Among neonates, the disease is severe, with a mortality of up to 80%. The most common etiologic agent in this type of meningitis is Escherichia coli. Meningitis due to Citrobacter diversus has occurred in sporadic small outbreaks throughout the United States. This devastating disease frequ...
