چکیده
Natural transmission of Entamoeba histolytica from infected mother cynomolgus monkeys (Macaca fascicularis) to their newborn infants was investigated by the stool examination under indoor individually-caged conditions. Every infant became positive for E. histolytica between 5 and 10 weeks after birth. Although some infants were demonstrated to harbor the trophozoites, no overt amebic diarrhea occurred in any of the infants throughout the period of this study.

Allele frequency of antiretroviral host factor TRIMCyp in wild-caught cynomolgus macaques (Macaca fascicularis)
A recent study showed that the frequency of an antiretroviral factor TRIM5 gene-derived isoform, TRIMCyp, in cynomolgus macaques (Macaca fascicularis) varies widely according to the particular habitat examined. However, whether the findings actually reflect the prevalence of TRIMCyp in wild cynomolgus macaques is still uncertain because the previous data were obtained with captive monkeys in br...

The changes in the serum immunoglobulin (Ig) level and in the measles antibody titer were examined with colony-born infant cynomolgus monkeys from 0 day to 26 weeks in age. In addition, their mother-monkey's milk was analyzed for Ig. The decrease in the IgG level after birth was more remarkable in the infants born with high IgG levels than those born with low IgG levels. The IgM level prominent...
متن کاملA natural model of behavioral depression in postpartum adult female cynomolgus monkeys (Macaca fascicularis).
Postpartum depression (PPD) is a modified form of major depressive disorders (MDD) that can exert profound negative effects on both mothers and infants than MDD. Within the postpartum period, both mothers and infants are susceptible; but because PPD typically occurs for short durations and has moderate symptoms, there exists challenges in exploring and addressing the underlying cause of the dep...
متن کاملStress in cynomolgus monkeys (Macaca fascicularis) subjected to long-distance transport and simulated transport housing conditions.
The stress associated with transportation of non-human primates used in scientific research is an important but almost unexplored part of laboratory animal husbandry. The procedures and routines concerning transport are not only important for the animals' physical health but also for their mental health as well. The transport stress in cynomolgus monkeys (Macaca fascicularis) was studied in two...
متن کاملPrevalence of rickettsial antibody and cell-mediated reaction in cynomolgus monkeys (Macaca fascicularis).
Serologic studies on feral, colony-held cynomolgus monkeys indicated that 61% reacted to Coxiella burnetii antigens, and 36% reacted to Rickettsia conorii antigens. The results suggest that a high percentage of cynomolgus monkeys have been exposed to these organisms.
