Detection of bovine viral diarrhea virus in 143 blood samples by virus isolation in cell culture and flow cytometry was performed. The material included 37 samples later shown to originate from persistently infected cattle. Thirty-three samples were positive by virus isolation, and all 37 samples were positive by the flow cytometric assay.

The incorporation of 2.5 micrograms/ml of cloxacillin into 5% bovine blood agar provided an inexpensive, easily prepared culture medium for the primary isolation of Moraxella bovis from bovine lacrimal and nasal secretions. With this medium, the time required to identify and isolate M. bovis from large numbers of field specimens was substantially reduced, whereas the sensitivity of isolation wa...

the present study was carried out to investigate the occurrence of total mycobiota and aspergillus species at different stages of fig production and processing in iran. in the meantime, the potential of different culture media for isolation of fungal species from figs was also investigated. the mycobiota of 389 samples of dried fig were studied. total fungal counts ranged from
