Current definition of inflammation by its cardinal signs is obsolete and unsuitable for guiding adequate therapeutic strategies. Furthermore, present theory of the inflammatory process regarding vascular phenomena as essential for generation of cardinal signs is invalid and unable to explain well established empirical facts, particularly the extent of the osmotic pressure and temperature variations within the inflamed tissue.

Molecular studies of European classical rabies viruses (RABV) have revealed a number of geographically clustered lineages. To study the diversity of Balkan RABV, partial nucleoprotein (N) gene sequences were analysed from a unique panel of isolates (n5210), collected from various hosts between 1972 and 2006. All of the Balkan isolates grouped within the European/Middle East Lineage, with the majority most closely related to East European strains. A number of RABV from Bosnia & Herzegovina and Montenegro, collected between 1986 and 2006, grouped with the West European strains, believed to be responsible for the rabies epizootic that spread throughout Europe in the latter half of the 20th Century. In contrast, no Serbian RABV belonged to this sublineage. However, a distinct group of Serbian fox RABV provided further evidence for the southwards wildlife-mediated movement of rabies from Hungary, Romania and Serbia into Bulgaria. To determine the optimal region for evolutionary analysis, partial, full and concatenated N-gene and glycoprotein (G) gene sequences were compared. Whilst both the divergence times and evolutionary rates were similar irrespective of genomic region, the 95 % highest probability density (HPD) limits were significantly reduced for full N-gene and concatenated NG-gene sequences compared with partial gene sequences. Bayesian coalescent analysis estimated the date of the most common recent ancestor of the Balkan RABV to be 1885 (95 % HPD, 1852(95 % HPD, -1913, and skyline plots suggested an expansion of the local viral population in 1980-1990, which coincides with the observed emergence of fox rabies in the region.

Urban (principally canine-mediated) rabies has been a public health risk for people living in Serbia for centuries. The first legal act in urban rabies prevention in Serbia was established in 1834 by introducing high taxes for pet dog owners. Five years later in 1839, the first set of literature describing rabies prevention was issued by the health department from The Serbian Ministry of Interior. An overview of cauterization of rabies wounds was presented as the principal method of rabies post exposure prophylaxis. In 1890, a human rabies vaccination was introduced in Serbia with the royal government directive which ordered patients to be treated at the Pasteur Institute in Budapest in receipt of rabies vaccination. Urban (canine) rabies was eliminated during the 1980s, but sylvatic (principally fox-mediated) rabies still prevailed. The last human rabies case was recorded in the Province of Kosovo and Metohija in 1980. Sylvatic rabies in Serbia is in the final stages of elimination by orally vaccinating foxes (Vulpes vulpes). The only published finding of a lyssavirus among Serbian bats was made in 1954 by Dr Milan Nikolić in the vicinity of Novi Sad. In 2006, a comprehensive two-year active surveillance program of lyssaviruses in bats in Serbia was undertaken. In this single study, all of the bats from Serbia tested negative for a lyssavirus.
