Lesion Morphology

Sections of tuberculous lesions from 23 elk ( Cervus elaphus nelsoni) and red deer ( Cervus elaphus elaphus), 12 fallow deer ( Dama dama), 10 sika deer ( Cervus nippon), and 30 cattle were examined and compared. Lesions were scored for caseous necrosis, mineralization, neutrophils, macrophages, giant cells, and acid-fast bacilli. Some differences in lesion morphology between the species were noted. Elk/red deer lesions had marked variation and often differed from bovine lesions in several characteristics; elk/red deer lesions usually had scattered peripheral mineralization rather than central mineralization and contained more neutrophils and fewer giant cells than did bovine lesions. Fallow deer lesions contained more giant cells but were otherwise indistinguishable from elk lesions. Sika deer lesions had more giant cells and fewer neutrophils than did lesions from cattle or other cervid species. Sika deer giant cells were larger and contained more nuclei than did giant cells in the other species.

Variation in PrP prion gene sequence appears to modulate susceptibility to chronic wasting disease (CWD), a naturally occurring prion disease affecting four North American species of the family Cervidae. Wapiti (Cervus elaphus nelsoni) PrP is polymorphic at codon 132 [methionine (M) or leucine (L)]. We genotyped 171 samples, collected between 2002 and 2005 from CWD-infected and uninfected wapiti from three free-ranging populations in Colorado, USA, to study influences of PrP polymorphisms on CWD susceptibility further. Overall genotype frequencies for 124 apparently uninfected animals were 65.3 % MM132, 32.3 % ML132 and 2.4 % LL132; for 47 CWD-infected animals, these frequencies were 70.2 % MM132, 27.7 % ML132 and 2.1 % LL132. Surprisingly, our data revealed that, among recent (approx. 2002–2005) CWD cases detected in free-ranging Colorado wapiti, the three PrP codon 132 genotypes were represented in proportion to their abundance in sampled populations (P≥0.24) and all three genotypes showed equivalent susceptibility to infection.

Abstract In 2021, work began as a part of the implementation of the decision of the protocol of the Sakhalin branch of the Russian Expert Council on earthquake prediction, seismic hazard and risk assessment dated October 6, 2020 on detailed monitoring in the area of active coal mining at the Solntsevsky open pit coal mine (Sakhalin Island). New points of seismic monitoring were installed directly in the area of the open pit coal mine. Integration of real-time data received from the points in real time into a unified seismic monitoring system in the Sakhalin Region was ensured. The results of registration of seismic events of various origins since the commissioning of the stations are presented. A significant increase in the accuracy of the determined epicenters and the possibilities of determining earthquakes and industrial explosions has been noted. The results of the monitoring system for studying the landslide process in the area of the open pit coal mine, as well as the probable factors that caused the landslide, are shown. The developed monitoring system allows for representative registration of seismic events with ML ≥ 0.8 in the immediate vicinity of open pit coal mine, which makes it possible to control blasting operations with increased accuracy, as well as weak and possible induced seismicity formed as a result of a constant technogenic impact on the subsoil.
