Metafillactic efficiency of florfenicol, applied to the fodder of the pigs from the fattening infected with Mycoplasma hyopneumoniae

The field research has been conducted with 390 pigs, which have are the same weight and age and are affected by a subclinical form of enzootic pneumonia. The pigs have been divided into two groups. First group has been receiving concentrated forage, combined with the antibiotic medicine Florfenicol in dose 2.0 kg Feniveex-2% premix/1000 kg fodder, for 7 days. Second group has been receiving the same fodder, but with the supplement Tylosin in dose 1.0 kg Tylovet-10% premix/1000 kg, for 21 days (positive control). The pigs from both groups have been observed for a period of 30 days, aftere the beginning of the treatment with medical fodder. The field research has demonstrated, that the Florfenicol used in the beginning of the fattening has proved effective in the control of the enzootic pneumonia, in comparison with the group that has been receiving Tylosin. It is established improvement of the clinical status of the animals, decrease in death, lowering the damage of the lungs and an increase in the average daily growth

A molecular study on Hepatitis E virus (HEV) in pigs in Bulgaria

Information on hepatitis E virus (HEV) strains circulating in animal reservoirs in Bulgaria is currently lacking. Herein, by screening HEV seropositive sera obtained from Bulgarian swine and wild boars, viral RNA was detected at high prevalence rate (28.2%) in industrial pigs. Sequence analysis of the partial polymerase (RdRp) region revealed the highest genetic correlation with HEVs of genotype (Gt) 3 identified in French and Dutch patients. For three such strains, a 700-bp fragment of the open reading frame 2 gene was generated. On phylogenetic analysis, the Bulgarian strains clustered tightly (93.8–98.3% nt) with human and animal HEVs classified within the Gt3 subtype c
