Severe hemorrhagic enterocolitis was observed in a Siberian tiger (Panthera tigris altaica) and a lion (Panthera leo). Both animals developed acute depression, anorexia, and bloody diarrhea several days before death. Small and large intestines were diffusely congested, edematous, necrotic, and filled with hemorrhagic fluid, and mesenteric lymph nodes were enlarged and congested. Pure and abunda...

Mammalian bites present a considerable clinical problem because they are often associated with bacterial infections. Pasteurella multocida is a microorganism that commonly infects both canine and small feline bites. Zoonotic infections developing after large feline bites have been recognised, although their reports are limited. We describe a 35 year old man who was bitten by a Siberian tiger an...

Polycystic kidney disease (PKD) is an inherited commonly reported in cats, but rarely big cats. It associated with formation of cysts the kidneys. This article describes clinical, pathology and immunohistochemistry findings PKD a Siberian hybrid tiger. A 16-year-old female captive tiger showed inappetence, weight loss, polyuria, polydipsia. Within six months, its body hydration status were prog...

A novel strain of Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV-27) was isolated from dead larvae of a Western Siberian (WS) population of gypsy moths (Lymantria dispar L.). We report the complete genome sequence of this strain, comprising 164,108 bp and double-stranded circular DNA encoding 162 predicted open reading frames.

We describe here the main characteristics of a new species isolated from Siberian permafrost dated around 10 million years. This species was named 'Bacillus massiliglaciei' strain Marseille-P2600T (= CSUR P2600 = DSM 102861).

We report the complete genome sequence of Carnobacterium gilichinskyi strain WN1359, previously isolated from Siberian permafrost and capable of growth under cold (0°C), anoxic, CO2-dominated, low-pressure (0.7-kPa) conditions in a simulation of the Mars atmosphere.
