| Collection Summary: | Animals were divided into three different groups: healthy controls (Mtb-, n=6), infected mice four weeks post-infection (Mtb+4w, n=6) and infected mice twelve weeks post-infection (Mtb+12w, n=5). Seven- to eight-week-old female BALB/c mice were purchased from Jackson Laboratories. Mice were housed in a pathogen-free facility with ad libitum access to water and food. All the animal studies were performed following the guidelines approved by IACUC at the University of Alabama at Birmingham, USA. Mice were aerosol infected with Mtb H37Rv using the aerosol inhalation exposure system (Glas-Col, USA) to deliver ~120-250 CFU/mouse lung. The infection dose was estimated by enumerating the lung CFU at 24 hours post-infection. Mice were sacrificed using anaesthesia with isoflurane followed by gentle cervical dislocation. Mice organs were aseptically harvested and homogenized in 2 ml of 1x PBS, pH 7.4. Serial dilutions of homogenates were prepared in 1x PBS and plated on 7H11 agar plates supplemented with 10% ADS (Albumin, Dextrose, and NaCl), Carbenicillin (25 mg/L) and Cycloheximide (25 mg/L). Plates were incubated at 37 °C for ~21 days before counting colonies. Finally, lung samples were transferred to an N2(l)-containing recipient to freeze the tissues and stored at -80 °C to avoid postmortem metabolic processes. |
