Previous studies have investigated rabies virus (RABV) epizootiology in Brazilian free-tailed bats (Tadarida brasiliensis) in natural cave roosts. However, little is known about geographic variation in RABV exposure, or if the use of man-made roosts by this species affects enzootic RABV infection dynamics within colonies. We sampled rabies viral neutralizing antibodies in bats at three bridge a...
Wild animals have been maintained in close association with humans since the dawn of human creation. Tremendous advances have been made in the care and management of wild animals, but some areas still need improvement. It is therefore important to identify the husbandry factors which minimize or maximize the occurrence of infectious or parasitic diseases. A universal influence on all animals is...

This aimed Coxiella burnetii infection its State. total 400 blood samples consisting 259 from females 141 males were aseptically collected jugular vein flocks The sera obtained screened for using an indirect enzyme-linked immunosorbent assay ...
A survey incorporating field and abattoir studies was carried out on the prevalence of Dicrocoelium dendriticum in sheep and goats in the Kangra valley of Himachal Pradesh (India). Coprological studies on these migratory animals revealed that 8.1% of sheep and 4.1% of goats were positive for dicrocoeliosis, with a mean number of eggs per gram of faeces (EPG) of 702.1 for sheep and 566.7 for goa...
Infection patterns with ectoparasitic flagellates belonging to the genus Ichthyobodo were studied in an Atlantic salmon Salmo salar (L.) hatchery in western Norway during an 11 mo period, from eyed eggs to smoltification. Since the earlier species designation Ichthyobodo necator (sensu lato, s.l.) has been shown to represent a complex of several species, the epizootiology of different Ichthyobo...
The insect-pathogenic fungal pathogen Entomophaga maimaiga is endemic to northeastern Asia and was first found in North America in 1989. Due to repeated epizootics and spread within populations of the major forest defoliator in northeastern North America, the gypsy moth (Lymantria dispar), this pathogen has gained much notoriety. Although this pathogen was purposely introduced to North America ...
