Biological activity of the macrolide derived from tylosin against Pasteurella multocida and P. haemolytica (in particular) in vitro and P. multicida (in particular) in vivo has been tested on chicks. Remarkable inhibition of these viruses is obtained. It is also found active against Staphylococcus aureus, Streptococcus pyogenes and pneumoniae, Haemophilus influenzae, Mycoplasma gallisepticum, synoviae, hyorhinis and hyopneumoniae 222... 

One of the newer semi-synthetic macrolides for veterinary use is 3-0-acetyl-4"-6)-isovaleryltylosin (AlV-tylosin) (15) Figure 5.6). Its in vitro spectrum is similar to tylosin, but includes activity against some tylosin-resistant organisms in vivo, it attains higher serum concentrations than tylosin [61, 77], It has been reported to prophylactically control Mycoplasma gallisepticum-inAmceA air sac lesions and Treponema hyodysenteriae-swine dysentery after oral administration [293, 294].

The nature of mycoplasma receptor sites on erythrocytes or other mammalian cells has not been extensively investigated. Of seventeen mycoplasma serotypes investigated, four bind to putative sialic acid receptors (Manchee and Taylor-Robinson, 1969). Mycoplasma pneumoniae and Mycoplasma gallisepticum appear to attach to sialic acid receptors on the erythrocytes or tracheal epithelial cells. Pretreatment of...
