All animal experiments were conducted in accordance with protocols approved by the Johns Hopkins Animal Care and Use Committee. Four adult chinchillas (C. laniger, 450–650g) were anesthetized with ketamine/xylazine IM and then treated bilaterally with 0.5cc intratympanic injections of 26.7 mg/mL gentamicin buffered with sodium bicarbonate to pH 7.0. This regimen ablates 3D aVOR responses to head rotation by destroying Type I vestibular hair cells and denuding Type II vestibular hair cells of their stereocilia while leaving a viable population of Type II hair cell bodies and spontaneously firing ampullary and macular nerve fibers subjacent to the endorgan neuroepithelium (Hirvonen et al 2005 (link); Della Santina et al 2005b , 2007b (link), 2010 (link); Lyford-Pike et al 2007 (link); Fridman et al 2010 (link)).
For animal restraint during testing, a post was affixed to the animal’s skull using dental cement. For prosthetic electrical stimulation, each chinchilla was implanted with four pairs of electrodes. One pair was placed within or near each of the three semicircular canal ampullae, while the last pair served as reference electrodes and was implanted in the neck musculature. Electrodes consisted of Teflon coated 10% iridium/90% platinum wires of diameters ranging from 25um to 125um (Medwire, Sigmund Cohn Corp, Mount Vernon, NY). Distal ends of each wire were stripped 200 μm from the end. Electrode wires of 25 μm diameter were flamed to form a ball on the distal end in order to increase the contact area of the electrode-perilymph interface. This was necessary to avoid electrode corrosion and nerve injury that would otherwise occur during passage of stimulus currents (Robblee and Rose 1990 ).

Blood for serum was collected via cardiac puncture prior to immunization (pre) and one week after receipt of the second immunizing dose (immune) for all animals immunized via a preventative regimen. Animals immunized via a therapeutic regimen were bled prior to NTHI challenge and at study end.
NP lavages were performed on animals immunized via a preventative regimen prior to immunization, one week after receipt of the final dose and on days 3, 7, 10, and 14 after bacterial challenge by passive inhalation of 500 μl sterile pyrogen-free saline as previously described 24 (link).
Video otoscopy (using a 0°, 3-in. probe connected to a digital camera system) to monitor signs of tympanic membrane inflammation and/or presence of fluid within the middle ear space was performed and overall signs of OM were rated on a scale of 0 to 4+ as previously described 7 (link), 24 (link), 31 (link) . Middle ears with a score of ≥ 2.0 were always considered positive for OM as MEF is visible behind the tympanic membrane. Each middle ear was considered independent, and for each cohort, the percentage of middle ears with OM was calculated.
Epitympanic taps to retrieve middle ear effusions were performed on any chinchilla whose tympanic membrane was rated as ≥ 2.5 on a scale of 0 to +4.0. Epitympanic taps were not performed on ears ranked 2.0, due potential for perforation of the tympanic membrane to retrieve the low volume of MEF. NP lavage and middle ear fluids were serially diluted and plated onto chocolate agar supplemented with 15 μg ampicillin/ ml medium or chocolate agar, respectively, to semi-quantitate CFU NTHI per ml fluid type. The mean CFU NTHI/ ml fluid was reported for each cohort.

For this review we also examined and photographed archival slides of brainstems from chimpanzees, monkeys, cats and several rodents (chinchilla, rat, guinea pig). Table 2 lists the animal cases. Cresyl and immunostained sections from several species (chimpanzee, monkey, cat, chinchilla, guinea pig, rat) were prepared in the laboratory at the University at Buffalo (Baizer and Baker, 2005 (link), 2006a (link),b (link); Manohar et al., 2012 (link); Baizer et al., 2013a (link),2015 (link); Paolone et al., 2014 (link)). Details of tissue acquisition and histology were given in those publications. In addition, we examined stained sections of chimpanzee, monkey and cat brains that had been prepared in other laboratories (see Table 2).

A standard PLVF toxicity study was performed in rabbits. Chinchilla male and female rabbits were purchased from the Federal State Budgetary Institution of Science “Scientific Center for Biomedical Technologies of the Federal Medical and Biological Agency”, Russia. Acute toxicity studies were performed with a single subcutaneous injection of 125 μg/0.5 mL of PLVF (5 male and 5 female rabbits per group, aged 3 months at the start of experiment and weighing 2708 ± 71 g), followed by observation for 14 days. Animals in the control group were injected with 0.5 mL of PBS. Chronic toxicity studies were performed with daily subcutaneous immunization of rabbits with 125 μg/0.5 mL PLVF for a week (5 males and 5 females per group), followed by observation for 7 days. Animals in the control group were injected with 0.5 mL of PBS. Blood samples for hematology and biochemistry were collected before vaccination, and 7 and 14 days after vaccination. On the 14th day after vaccination, necropsy, histological examination of 16 internal organs and tissues of each rabbit, and the blood differential test were performed. The local irritation was studied by histopathological evaluation of the site of repeated subcutaneous injection of the vaccine preparation (macro- and microscopic description of the skin at the injection site).
Tissue samples for histological examination were fixed in 10% neutral buffered formalin, dehydrated in ascending concentrations of alcohol, and embedded in paraffin. Paraffin sections 5 μm thick were cut on a SM 2000R microtome (Leica, Wetzlar, Germany), stained with hematoxylin and eosin, and examined using a DM1000 microscope (Leica, Wetzlar, Germany).
The study of acute and chronic toxicity, as well as the study of the local tolerance of PLVF, was carried out in accordance with the recommendations and the requirements of local legislation (Federal Law of 12.04.10 N 61 “On the Circulation of Medicines”).

This study included 10 adult chinchillas (5 males and 5 females), ranging in age from 1–2 years, which belong to a commercial farm in Beijing, China. No animals participating in the study received any treatment prior to the experiment. Chinchillas were placed in individual cages, within a climate-controlled room temperature maintaining between 21 °C and 23 °C, and they were provided with a commercial pelleted diet (Mazuri® Chinchilla Diets, Land O’Lakes, Inc., Melrose, MN, USA) with fresh timothy hay and tap water ad libitum. All animals were clinically healthy based on normal physical examination and close observation of food intake and fecal output. The shape and color of all fecal pellets during the experiment were normal, and for fecal samples collected from the 10 chinchillas on day 0 (before ivermectin injection) and day 14 (14 days after ivermectin injection), no gastrointestinal parasites were found in fecal fresh smear and zinc sulfate floating test under microscopic examination. Our study was approved by the animal care and use committee of China Agricultural University and we obtained the informed consent statement from the breeder.

Within subjects, we performed a before and after study instead of a cross over study given that the necessary washout period of ivermectin in chinchillas is unknown. In this experiment, the 10 chinchillas were injected subcutaneously with ivermectin injection (Ivomec®, Merial, Ingelheim am Rhein, Germany, 1.0% w/v sterile solution, dilute 10 times by saline) 0.4 mg/kg on day 0.
Fresh fecal samples were collected on day 0 and day 14, divided into day 0 group and day 14 group, respectively. Chinchillas were placed individually into clean cages, and fecal pellets were collected upon evacuation. Following collection, these samples were transferred immediately into sterile cryogenic vials by sterile forceps and stored at −80 °C until microbiota analysis [14 (link)].

We obtained all available coding sequence isoforms from NCBI RefSeq for eight genes known to be involved in thyroid function (Tpo, Tg, Duox1, Duox2, Duoxa1, Duoxa2, Pax8 and Slc5a5), belonging to guinea pig (Cavia porcellus), chinchilla (Chinchilla lanigera), mouse (Mus musculus), rat (Rattus norvegicus) or any species of the Bathyergidae family. Because the proportion of gaps and poorly alignable regions tends to increase with each additional species in the analysis, leading to the exclusion of more positions from the analysis, we made a conscious decision to limit the number of species used. An important reason for this decision was that we tested positive selection in only one species (rather than an entire clade). In this case it is sufficient to identify sequence divergences in the target species that on the one hand represent differences from multiple closely related species (other mole-rat species or guinea pig), while on the other hand the consensus sequence at those positions is conserved over long evolutionary distances (chinchilla, mouse, rat).
We then used the PosiGene pipeline to test these genes for positive selection and identify selected sites on the naked mole-rat branch by applying the branch-site test of positive selection31 (link),32 (link). Those genes resulting in a false discovery rate (FDR) < 0.1 were further analysed for potential misinterpretation of relaxed selection as positive selection using the RELAX framework33 (link).
