Mouse feces and pregnancy

Urine samples were stored frozen, then assayed for protein and creatinine, and ratios of protein to creatinine were calculated to correct for urine concentration. The ability to predict pregnancy from the presence of a vaginal plug also varies significantly with strain [6]. Conclusion : We conclude that enzyme immunoassays of fecal samples for progesterone metabolites may be a promising approach for reliable and non-invasive pregnancy detection in mice. This finding makes the fecal progesterone assay a viable method of pregnancy detection, because the organogenesis stage is a major focus of developmental biology research and represents a stage of gestation before the mouse is visibly pregnant. Fecal pellets are easier to obtain than urine samples in a mouse, and as few as one single fecal pellet is sufficient to detect progesterone levels by an enzyme immunoassay.

    The virus, says Barton, appears mostly in mice and some hamsters and generally is passed along in urine and feces. Pregnant women can.

    Lymphocytic choriomeningitis, or LCM, is a rodent-borne viral infectious disease caused Additionally, pregnancy-related infection has been associated with with urine, feces, saliva, or blood of wild mice are potentially at risk for infection.

    Last Updated: Aug 15, Fecal progesterone has also been measured and used to determine reproductive status in a wide variety of species, including the baboon, elephant, wolf, sun bear, sea otter, right whale, and elk [], but there is little information on fecal progesterone levels in the pregnant mouse. August 6, That's precisely why, Barton says, she penned the new journal article.

    Our results thus suggest that enzyme immunoassays of fecal samples for progesterone metabolites may be a promising approach for a reliable and non-invasive pregnancy detection method in mice.

    Barton believes that the public and the medical profession should be made aware of the hazard that wild, pet and laboratory rodents pose to pregnant women.

    Such a test would benefit developmental biology researchers and reduce the unnecessary sacrifice of non-pregnant laboratory mice during early gestation and before pregnancy is reliably detected or outwardly visible. Once the assay validation was complete, 78 test fecal samples from pregnant and non-pregnant mice were analyzed for progesterone content.

    Barton, however, believes what we don't know about LCMV is probably greater than what we do know.

    Pregnant women should be cautious about contact with pet hamsters, wild or laboratory mice according to a study by UA pediatrician Dr. Leslie Barton. touch mouse or rat urine, droppings or bedding materials that risk of infection from pet rodents is generally low, pregnant women should be.

    Learn how to safely care for your pets during pregnancy. Cats pass this parasite in their feces (poop), and you can get it by cleaning kitty litter or touching dirt, Many peoples have rodents, including mice, hamsters and guinea pigs, as pets.
    Such a test would benefit developmental biology researchers and reduce the unnecessary sacrifice of non-pregnant laboratory mice during early gestation and before pregnancy is reliably detected or outwardly visible.

    July 15, The widely-studied embryonic period of organogenesis, when most organs form and are particularly sensitive to teratogens, occurs during embryonic days E 6. Protein concentration was determined by solving the equation of the line for each sample. Ultrasound imaging can be used to detect pregnancy post-implantation E6.

    Mass spectrometry on excised bands identified major urinary proteins, centrosomal protein, and keratin, but no pregnancy-specific proteins. Fecal progesterone metabolites have been evaluated by radioimmunoassay and found to be elevated in ovulating hamsters [14].

    However, human chorionic gonadotropin is not present in mice, and mouse urinary proteins have not been well evaluated for their potential use in pregnancy detection.

    The day of plug detection is considered either embryonic day 0.

    We hypothesized that a reliable and non-invasive murine pregnancy detection method could be developed using urine or feces from the pregnant dam that would ultimately reduce unnecessary sacrifice of non-pregnant laboratory mice.

    Barton collaborates with Dr. But what we don't know is how much, how often, and how many are susceptible," says Barton.
