Fifty-one strains of Erwinia amylovora isolated from nine host plants in Bulgaria were characterized phenotypically and identified by the API 20E and BIOLOG system. The identification was confirmed by PCR amplification of a specific region of the plasmid pEA29 and the genome ams region. The phenotypic diversity of the strains was studied on the basis of their API 20E and BIOLOG metabolic profil...

The ban of organochlorine pesticides in Bulgaria (1969) has led to their significant drop below the maximum residue limits. The climate and the imperfect storage facilities benefit the production of Fusarium toxins desoxynivalenol (folytoxin), zearalenon (F-2), T-2, ochratoxin A and aflatoxins in grain products, M1 in milk products, and patulin in apple juices and nectars. Heavy metals are foun...

On March 15, 2010, a highly pathogenic avian influenza virus was isolated from the carcass of a common buzzard (Buteo buteo) in Bulgaria. Phylogenetic analyses of the virus showed a close genetic relationship with influenza virus A (H5N1) clade 2.3.2.1 viruses isolated from wild birds in the Tyva Republic and Mongolia during 2009-2010. Designated A/common buzzard/Bulgaria/38WB/2010, this strain...

Two species of tortoises are naturally presented in the territory of Bulgaria – Testudo graeca (Spurthighed tortoise) and Testudo hermanni (Spurtailed tortoise)(Pic1). Both are endangered species, included in the Red List of (IUCN-2003). –Testudo graeca is in Vulnerable category and Testudo hermanni in Low risk category. The species are also included in the Bern Convention, ratified from Bulgar...

The karyotype and meiosis in males of giant water bug Lethocerus patruelis (Heteroptera: Belostomatidae: Lethocerinae) were studied using standard and fluorochrome (CMA3 and DAPI) staining of chromosomes. The species was shown to have 2n = 22A + 2m + XY where 2m are a pair of microchromosomes. NORs are located in X and Y chromosomes. Within Belostomatidae, Lethocerus patruelis is unique in show...

As a result of dramatic political and economic changes in the beginning of the 1990s, Q-fever epidemiology in Bulgaria has changed. The number of goats almost tripled; contact between goat owners (and their families) and goats, as well as goats and other animals, increased; consumption of raw goat milk and its products increased; and goats replaced cattle and sheep as the main source of human C...

The frequency of erythromycin resistance within group A streptococci in Sofia, Bulgaria, from 1995 to 2001 was 2.1% (26 isolates). Of this, 57.7% was macrolide-lincosamide-streptogramin (MLS) inducible, 7.7% was MLS constitutive, and 34.6% had the M phenotype. Eleven different emm sequence types were found among 25 erythromycin-resistant isolates tested. Nineteen of 26 erythromycin-resistant is...
