Multidrug-resistant Gram-negative bacteria such as Acinetobacter baumannii,
Pseudomonas aeruginosa, and members of the Enterobacterales order are a challenging …

Porcine breeding today is based on artificial insemination with chilled semen. This is stored
at 5° C with antibiotic supplementation to avoid bacteriospermia. There are many negative …

The use of antibiotics with semen extender appears to be a practical solution to minimise
bacterial growth in fresh boar semen preservation. Unfortunately, the excessive use of …

Antimicrobial resistance is an increasing challenge in semen preservation of breeding
animals, especially in the porcine species. Bacteria are a natural component of semen, and …

The primary role of semen processing and preservation is to maintain a high proportion of
structurally and functionally competent and mature spermatozoa, that may be used for the …

Multi-drug antibiotic resistance of Serratia (S.) marcescens and Klebsiella (K.) oxytoca in
boar semen is an emerging threat to pig reproduction and the environment. The aim of this …

The aim of this study was first to examine the prevalence of bacteria-associated loss of
sperm quality in samples from insemination centers during a seven-year semen monitoring …

Introduction Facing the global threat of antimicrobial resistance, the reduction of antibiotic
use in semen extenders is a main goal in artificial insemination (AI) of pigs. The aim of this …

Background Commercial porcine semen is stored at 17° C, leading to a reduction of sperm
quality and increase of bacterial growth. Objectives To evaluate the effect of 5° C storage on …

Bacterial infestation of the male reproductive system with subsequent effects of bacteria on
the structural integrity and functional activity of male gametes has become a significant factor …
