A Review of Mycoplasma in Laboratory Mice
Mycoplasma are small, cell-free bacteria enclosed by a membrane. These bacteria belong to the class of Mollicutes, the order of Mycoplasma tales, and the genus of Mycoplasma. There are more than 100 identified species of mycoplasma. The ratio of cytosine to guanine in its DNA is 23–40% and its genome size is 1350–600 kb. Mycoplasma require cholesterol to grow, and the temperature su...
متن کاملStudy of zoonotic bacteria in conventional laboratory mice breeding colonies
To investigate the status of conventional laboratory mice colonies for zoonotic bacteria, three mice colonies, NIH, NMRI and Balb/c strains of Razi institute were studied for five zoonotic bacteria including Pasteurella pneumotropica, Salmonella typhimurium, Salmonella enteritidis, Streptobacillus moniliformis, Streptococcus Pneumonia. Study populations were 74 mice of premature, mature and pos...
متن کاملLimits to sustained energy intake. VII. Milk energy output in laboratory mice at thermoneutrality.
The limits to sustained energy intake at peak lactation could be imposed peripherally, by the capacity of the mammary glands, or centrally, by the capacity of the animal to dissipate body heat generated as a by-product of processing food and producing milk. To distinguish between the two hypotheses, we examined milk energy output at peak lactation in MF1 laboratory mice exposed to 30 degrees C ...
متن کاملthe effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows
پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
klossiella muris infection in laboratory mice
klossiella muris is ordinarily nonpathogenic, although in heavy infections the kidneys may have minute grayish necrotic foci over their entire surface and the epithelium of the infected kidney tubules may be destroyed. for histopathological diagnosis of klossiella muris infection, kidneys of 24 mice were studied that klossiella in various stages of development were observed in the renal tubules...
