Chemicals: Ciprofloxacin, enrofloxacin, sulfamethazine, sulfaquinoxaline, tetracycline, oxytetracycline, chlortetracycline, erythromycin and tylosin
were purchased from Sigma-Aldrich, (95%; European Pharmacopoeia HPLC assay, product of China; Shanghai, Trading Co., Ltd.).
In Australia, the growth promoters used for pigs are flavophospholipol, kitasamycin, tylosin
, olaquindox and virginiamycin.
Generally, clostridial infections respond very well to amoxicillin or Tylosin
, so your veterinarian may try a course of antibiotics to both diagnose and treat the diarrhea.
is a macrolide bacteriostatic antibiotic used in sheep, goat, cattle and swine for treatment of local and systemic infections caused by Mycoplasma.
Effects of in-feed copper and tylosin
supplementations on copper and antimicrobial resistance in fecal enterococci of feedlot cattle.
Concentrations in surface waters and groundwater were 0.36 [micro]g/l of lincomycin and 1.5 [micro]g/l of tylosin
, whereas concentrations in treated water were generally below 5 x [10.sup.-2] [micro]g/l (or 50ng/l) .
Experts recommend implementing parenteral (intravenous) treatment on acute cases like summer mastitis [15, 46], because intramammary or local administration might not be the adequate route, due to intense pus discharge and inflammatory reaction: Considering that in vitro assays can show a wide spectrum of susceptibility to different antimicrobial families [28, 44], will be appropriate to evaluate antibiotics with high bioavailability on mammary gland or milk as P, sulfonamides and macrolides like E or tylosin
; nevertheless, there are several reports of T pyogenes strains resistant to the them [11, 44, 46] so, the use of these antibiotics should be considered according to results of respective antimicrobial susceptibility tests.
The most common drugs used included oxytetracycline, penicillin, tylosin
, ciprofloxacin, erythromycin, enrofloxacin, streptomycin, doxycycline, trimethoprim-sulfadozine, and neomycin.
According to their study, Gentamicin was (96.15%), enrofloxacin (92.31%), Trimethoprim-sulpha (88.46%), Amoxicillin (84.62%), Tetracycline (80.72%), Tylosin
(80.77%), Lincomycin (76.92%), Ampicillin (46.15%) and Pencillin G (42.31%) effective against SCM in goats.
The limits of quantification for the residues screened using the KIS test were as follows: penicillin G (0.03-0.04 [micro]g/mL), oxytetracycline (3.0 [micro]g/mL), tylosin
(0.4 [micro]g/mL), gentamicin (0.75 [micro]g/mL), sulfadimethoxine (0.25 [micro]g/mL), sulfamethazine (0.5 [micro]g/mL), neomycin (4.0 [micro]g/mL), and tulathromycin (1.0 pg/ mL).
