However, such models are often underutilized due to practical challenges. These challenges include the need for specialized surgeries and the presence of complicating symptoms, such as ascites fluid accumulation in ovarian cancer and liver disease models, as well as ulceration of breast tumors growing in the mammary fat pad. An adaptable, quantitative animal health assessment system that employs simple, noninvasive visual measurements can enable researchers to realize the full potential of these models while safeguarding humane endpoints. The goal of this work was to establish health-scoring systems for translationally relevant ovarian (ID8-Defb29/Vegf-A) and breast cancer (triple-negative 4T1) models. We developed a tractable health assessment system by monitoring a combination of activity and responsiveness, hair coat condition, respiratory function, changes in body weight, posture, gait, tumor size (where measurable), and extent of ulceration, and scoring each parameter on a simple numerical scale. The scores at which euthanasia or other interventions were required were estimated and then adjusted based on clinical assessment by a team of researchers and veterinarians. These semiquantitative health-scoring systems were applied to survival experiments, in which mice were euthanized at a predetermined score or upon meeting a superseding health criterion, to confirm their applicability and effectiveness in maintaining humane endpoints. The scoring systems presented are intended to build on previously established generic tumor model scoring systems that do not account for the particular phenotypes present in orthotopic breast and ovarian cancer models.</p>","PeriodicalId":94111,"journal":{"name":"Journal of the American Association for Laboratory Animal Science : JAALAS","volume":" ","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641240/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148474999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to establish practical and reproducible methods for obtaining high-quality dental radiographs in rhesus macaques using the handheld X-ray system. Initially, anatomic landmarks, optimal X-ray beam, and sensor angles were determined using a preserved rhesus macaque skull. These techniques were subsequently applied to 12 anesthetized rhesus macaques for dental radiographic assessment and presurgical planning. Radiographs were successfully obtained for maxillary and mandibular incisors, canines, premolars, and molars. In addition, several examples of common dental pathologies, including periodontal disease, root resorption, and tooth fractures, were documented. This study provides detailed techniques for dental radiography in rhesus macaques, demonstrating its utility as a diagnostic adjunct for identifying dental pathology and planning oromaxillofacial surgical procedures. The use of dental radiographs enhances diagnostic accuracy, improves surgical outcomes, and contributes to the overall welfare of rhesus macaques in research and clinical settings.

The Guide for the Care and Use of Laboratory Animals recommends changing tops every 2 weeks but allows performance-based intervals when supported by data. This study evaluated whether mouse wire-bar lid sanitation intervals can be extended to 8 weeks without increasing organic or microbial load. In a 10-week study across 5 cage configurations, wire-bar lids were sampled at weeks 0, 2, 4, 6, 8, and 10. Organic residue was quantified by ATP luminometry (relative light units [RLUs]) and viable bioburden by total plate count (TPC; CFU/cm2) using Hygicult TPC contact agar. Prespecified action thresholds were ATP ≤100,000 RLU and TPC ≤45 CFU/cm2. All values remained below thresholds; ATP was consistently <5% of the action level and TPC maxima <40% of the action level. Two one-sided tests on log-transformed data demonstrated biologic equivalence between week 8 and week 2 across all configurations, with 90% CIs fully within prespecified margins (±10,000 RLU; ±4.5 CFU/cm2). Under these conditions, extending the wire-bar lid sanitation interval to 8 weeks was feasible without evidence of increased organic load or bioburden. Based on facility census and time-and-motion data, the change is projected to save ∼22,075 kWh/y of energy, 166,270 L/y of water, and ∼1,125 labor hours (≈0.54 full-time equivalent).

However, due to their small size, accurate measurement of body temperature in neonatal and juvenile mice presents challenges. While rectal temperature is precise, it is invasive and stressful to both neonates and dams. Infrared technologies offer a potential alternative for assessing the body temperature of young mice. This study compared traditional rectal temperature to 3 alternative noninvasive methods: a surface probe and 2 infrared-based approaches (rodent infrared and human infrared). For each alternative method, temperature was measured at 3 different anatomic locations (dorsum, abdomen, and thorax). Temperatures were measured in mice of various ages from postnatal day (PND) 2-42. Temperature measurements were obtained in awake C57BL/6J (n = 114) and BALB/cJ (n = 113) mice to establish baseline neonatal mouse body temperature as they develop thermoregulation. Two strains of mice were used to determine whether coat color impacts infrared temperature readings. Results indicate that body temperature significantly changes as mice age for both strains. Temperatures from all 3 alternative temperature methods at all anatomic locations were significantly lower relative to rectal temperature. The surface probe had little variability among anatomic locations and closely followed the trend of the rectal thermometer with an average difference of 2.1-2.22 °C lower than rectal temperature. Of the methods assessed, the surface probe was the best alternative method to rectal temperature. These results provide valuable baseline data on normal neonatal mouse body temperature for 2 commonly used strains and suggest the surface probe could provide an alternative for body temperature measurement in young mice.</p>","PeriodicalId":94111,"journal":{"name":"Journal of the American Association for Laboratory Animal Science : JAALAS","volume":" ","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13446400/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148159651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple environmental (diet, light/dark cycles, etc.) as well as host-related factors (genotype, maternal effect, etc.) not only influence the animal experimental phenotype but also contribute to the shaping of the microbiome, raising the question of whether the microbiome of experimental animals represents an extrinsic, intrinsic, or intermediate influence. Currently, there is sufficient evidence that microbial communities at different body sites are shaped by distinct endogenous and exogenous factors, indicating that the host does not leave its microbial status to chance but instead actively modulates it through host-specific mechanisms, despite extrinsic influences. This leads to a microbiome that reflects a 'fingerprint' of its own endogenous and exogenous influences.

Assessing the clinical progression of lung injury in rodent models presents challenges due to their small size and limited ability to correlate physiologic outcomes with human disease. Furthermore, traditional methods for assessing lung injury rely on invasive techniques, including leukocyte quantification in lung tissue, analysis of bronchoalveolar lavage fluid, and histopathologic evaluation, most of which require euthanasia and preclude longitudinal assessments in the same animal. While body weight is a commonly used indicator of morbidity, additional noninvasive metrics such as pulse oximetry, heart rate, and respiratory rate may offer deeper insights into host responses. Here, we used the MouseOx Plus in conscious mice with a lipopolysaccharide (LPS)-induced lung injury to monitor cardiopulmonary parameters and determine whether there is a correlation between peak hypoxemia, body weight, and heart rate with the severity of the lung injury as defined by histologic assessment. We also evaluated the use of anesthesia to immobilize animals for collecting cardiopulmonary data, as is commonly done, and found that arterial saturation measurements were not significantly different in awake compared with anesthetized animals. However, body weight recovery was significantly decreased in anesthetized groups on days 4-5.
