Bovine herpesvirus type 4 (BHV-4) is related to many different conditions: infertility, postpartal metritis, vulvovaginitis, mastitis, encephalitis, calf pneumonia, keratoconjunctivitis, cutaneous lesions, digital dermatitis and abortion. In this study a retrospective PCR examination of 100 extracted DNA samples from aborting cows was performed in order to determine: prevalence of BHV-4 in abortive cattle, whether coinfections BHV-4 with other abortifacient pathogens are present in the same sample and to determine the month of gestation when BHV-4 associated abortions were detected. Out of 100 examined samples, the BHV-4 genome was detected in 21 samples (21%). In two samples we detected coinfection of BHV-4 with bovine viral diarrhea virus (BVDV) and in one with Neospora caninum. Most of the BHV-4-associated abortions were detected during the seventh month of gestation. It was concluded that an active BHV-4 infection was present among cows that aborted on the farms examined. The high prevalence of the BHV-4 genome in abortion material suggests that this virus may have cause the abortions. Further studies and examinations are needed to establish causative connection between presence of BHV-4 and abortion.

Photosynthetic efficiency and damage symptoms of Tamarix tetrandra Pallas, Populus alba L., Robinia pseudoacacia L. (planted), and Amorpha fruticosa L. (naturally colonized) were studied at two fly ash deposit lagoons of the 'Nikola Tesla - A' power plant (Obrenovac, Serbia), weathered 5 (L1) and 13 years (L2). In early phases of weathering, after 5 years, a reduced vitality of populations growing on the ash was noticed in planted R. pseudoacacia and spontaneously populated A. fruticosa (P<0.001) in comparison to T. tentandra and P. alba, due to higher salinity and elevated concentrations of As, Mo, Cu, and Mn in the ash. Thirteen years after planting, as weathering proceeded due to reduced salinity and toxicity, A. fruticosa species showed photosynthesis recovery and had the highest photosynthetic efficiency (P<0.001), suggesting that it poses adaptive capacity to survive and develop tolerance to stress in such habitats that strongly recommend this species for planting at fly ash lagoons.
