The disposition of penicillin G in piglets is described after intramuscular or subcutaneous injection of depot preparations. The piglets were injected with 33,000 IU/kg or 100,000 IU/kg benzathine + procaine penicillin G intramuscularly or subcutaneously, or 100,000 IU/kg procaine penicillin G intramuscularly or subcutaneously. Intramuscular injection of benzathine + procaine penicillin resulted in higher maximum concentrations in plasma (Cmax) than did subcutaneous injection. The mean residence time (MRT) of penicillin G was longer when the drugs were injected subcutaneously rather than intramuscularly. The plasma concentration versus time profiles of the subcutaneous injections of benzathine + procaine penicillin revealed secondary peaks, possibly reflecting a certain degree of inflammation at the injection site.

: Despite penicillin having a longstanding reputation as being scientifically approved for the treatment of bovine mastitis, its market share and practical application rate seem rather low. While in some countries, cases of mild and moderate mastitis are treated almost completely with simple penicillin, in other countries, penicillin is rarely used as a mono-substance in udder tubes. : Based on minimal inhibitory concentration (MIC) studies of 1489 isolates of Gram-positive microorganisms isolated from bovine mastitis cases, the extent to which penicillin preparations can fulfil their role as first-line treatment and in how many cases insufficient efficacy must be assumed was assessed in comparison with more recent studies on the achievable levels of active substances in milk.

Pakistan has a large, intensive broiler production industry, where antimicrobials are extensively used for both therapeutic and prophylactic purposes. Monitoring antimicrobial use (AMU) at the farm level is crucial to guide interventions for antimicrobial stewardship. The objective of this study was to comprehensively quantify AMU on commercial broiler farms in Pakistan using different metrics.

Ethnopharmacological Relevance: Pastoralists in Nigeria mix Garcinia kola seed (GK), Khaya senegalensis stem bark (KS), and Vernonia amygdalina leaves (VA) to treat leptospirosis.
Aim: To determine the in vitro and in vivo effect on single and combination therapy on Leptospira interrogans-infected mice.
Materials And Methods: Evaluation of in vitro assay for anti-leptospiral motility of the extracts was carried out in triplicates.
