1. Persistence of experimental Rocio virus infection in the golden hamster (Mesocricetus auratus)
Rocio virus (ROCV) is an encephalitic flavivirus endemic to Brazil. Experimental flavivirus infections have previously demonstrated a persistent infection and, in this study, we investigated the persistence of ROCV infection in golden hamsters (Mesocricetus auratus). The hamsters were infected intraperitoneally with 9.8 LD50/0.02 mL of ROCV and later anaesth

2. Determinação de elementos químicos inorgânicos em amostras de sangue total humano e de animais de experimentação (hamster dourado e cavalo da raça crioula) pela técnica de fluorescência de raios X(EDXRF) / Inorganic elements determination in human and animal whole blood samples by X-ray fluorescence technique (EDXRF)
Blood is a suspension of cells contained in a complex liquid called plasma. The term whole blood refers to samples with both solid and liquid parts. Inorganic elements are responsible for essential functions, such as osmotic regulation, cardiac frequency and contractibility, blood clotting and neuromuscular excitability. The determination of inorganic elemen

3. Presença de amastigotas em sistema nervoso central de hamster infectado com Leishmania sp.
A leishmaniose visceral (LV) é uma doença crônica grave, causada pelo parasito Leishmania (Leishmania) infantum chagasi. Esclarecer as alterações provocadas pela doença é fundamental para que se adotem condutas clínicas e de tratamento adequadas. Com o objetivo de analisar a infecção experimental em hamsters da linhagem golden, Mesocricetus auratus

4. Análise histopatológica e ultra-estrutural de órgão de hamster golden (Mesocricetus auratus) infectados com isolados de Leishmania do complexo Braziliensis
Leishmaniasis are zoonosis with different clinical manifestations according to the Leishmania species involved and the host immune response. Leishmania braziliensis complex is responsible for the majority of human Tegumentary Leishmaniasis cases in Brazil and it is endemic in the Triângulo Mineiro region. Our aim was to compare the pathogeny of two differen

5. New observations on the onset and duration of the meiotic prophase in the female golden hamster (Mesocricetus auratus).
The onset and evolution of the meiotic prophase were assessed by histological and cytological techniques in fetal and neonatal ovaries obtained from day 13 postcoitum to day 11 postpartum in the golden hamster (Mesocricetus auratus). The histological technique based on the Feulgen stain and the cytological technique based on the Giemsa stain of isolated nucl

6. Regional differences in the ultrastructural features of secretory cells in the golden hamster (Mesocricetus auratus) oviductal epithelium.
The secretory cells of the golden hamster (Mesocricetus auratus) oviductal epithelium on the day of ovulation were observed by light and electron microscopy. In the fimbriae two types of secretory cells were observed: one possessed secretory granules with electron-lucent matrices, prominent protrusions and many electron-dense granules resembling lipid drople

7. The development of the uteroplacental vascular system in the golden hamster Mesocricetus auratus.
The development of the uteroplacental vasculature in the golden hamster was studied by vascular casting and India ink injection methods. The hamster placenta usually has three sets of uteroplacental arteries and its maternal segment is derived from the medial arterial division of the non-pregnant uterus. The maternal segment consists of the spiral artery in

8. Membrane segregation in atrioventricular nodal myocytes of the golden hamster (Mesocricetus auratus). A cytochemical study using filipin and tomatine.
The membrane systems of hamster general atrial and ventricular myocytes were studied and their reactivity with the sterol probes, filipin and tomatine, compared with that of atrioventricular nodal myocytes. The sarcolemma of atrial and atrioventricular nodal myocytes was considerably more reactive to sterol probes than the sarcolemma of general ventricular m

9. Cloning of Syrian Hamster (Mesocricetus auratus) Cytokine cDNAs and Analysis of Cytokine mRNA Expression in Experimental Visceral Leishmaniasis
The Syrian golden hamster (Mesocricetus auratus) is uniquely susceptible to a variety of intracellular pathogens and is an excellent model for a number of human infectious diseases. The molecular basis for this high level of susceptibility is unknown, and immunological studies related to this model have been limited by the lack of available reagents. In this

10. Sensitivity and integration in a visual pathway for circadian entrainment in the hamster (Mesocricetus auratus).
1. Light-induced phase shifts of the circadian rhythm of wheel-running activity were used to measure the photic sensitivity of a circadian pacemaker and the visual pathway that conveys light information to it in the golden hamster (Mesocricetus auratus). The sensitivity to stimulus irradiance and duration was assessed by measuring the magnitude of phase-shif

11. Variation Between Strains of Hamsters in the Lethality of Pichinde Virus Infections
Infection by Pichinde virus, a member of the arenavirus group, was studied in Golden Syrian hamsters (Mesocricetus auratus) with regard to possible mechanisms of resistance to virus infection in adult hamsters. Two hamster strains were found to differ in their susceptibility to lethal Pichinde virus infection. LVG/Lak randomly bred hamsters were found to be

12. Isolation and characterization of Borrelia burgdorferi from blood of a bird captured in the Saint Croix River Valley.
Field investigations were conducted to further evaluate the role of birds in the maintenance and dissemination of Borrelia burgdorferi. Blood specimens were taken from 39 passerine birds of 17 species captured during June 1991 at the Saint Croix National Riverway in Wisconsin, and one isolate, WI91-23, was cultured from an adult song sparrow (Melospiza melod
