Isolation media consisting of Mycoplasma Broth Base (Becton Dickinson, Franklin Lakes, NJ) supplemented with dextrose (Thermo Fisher Scientific, Waltham, MA), L-cysteine hydrochloride monohydrate (Thermo Fisher Scientific), beta-NAD (Thermo Fisher Scientific), thallium acetate (Acros Organics, Fair Lawn, NJ), phenol red (Sigma Aldrich, St. Louis, MO), porcine serum (Quad Five, Ryegate, MT), equine serum (Quad Five), and penicillin G potassium salt (Sigma Aldrich) as both broth and agar plates. Mycoplasma plates were inoculated with the nasal wash used in the infection experiment. These plates were then incubated under microaerophilic conditions at 37°C for 10 days. Several of the resulting colonies were then determined to be M. ovipneumoniae through qPCR targeting the p133 gene (Yang et al., 2014 (link)) with Ct values <25. These colonies were inoculated into Mycoplasma broth and expanded by incubation under microaerophilic conditions at 37°C until acid production caused a color change in the media with the phenol red.

Splenocytes were prepared as described previously [39 (link)–41 (link)]. Briefly, immediately following sacrifice of the mice by cervical dislocation, spleens from BALB/c female mice were excised, teased apart in RPMI 1640 medium (Wako Pure Chemical Industries), and centrifuged. The single-cell suspension obtained was treated with ACK lysis buffer to lyse the red blood cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
