Malignant Brenner Tumor of the Ovary: A Critical Reappraisal.

Malignant Brenner tumors (MBTs) are rare epithelial tumors of the ovary, most likely arising from benign and borderline Brenner tumors. MBTs may be misdiagnosed as other primary carcinomas or nonepithelial tumors of the ovary as well as metastatic carcinomas. Accurate diagnosis usually requires clinical-radiologic correlation, extensive sampling, and immunohistochemical studies.

Detection of neutralizing antibodies against arboviruses from liver homogenates.

Yellow fever virus (YFV) circulates in a sylvatic cycle between non-human primates (NHPs) and arboreal mosquitoes in Brazil. Passive monitoring of ill or deceased NHPs is a key component of the Brazilian yellow fever (YF) surveillance program. Samples from NHPs carcasses are usually suitable for molecular tests but not for serological assays.

Near full-length genome sequence of a vesicular stomatitis New Jersey virus isolate collected from a naturally infected cow in the endemic state of Chiapas, Mexico.

Here, we report the near full-length genome sequence of a isolate obtained from a naturally infected cow () in the state of Chiapas, Mexico. This sequence will support future efforts to improve our understanding of the evolutionary dynamics of this pathogen in endemic regions of Mexico.

Vesicular Stomatitis Virus Transmission Dynamics Within Its Endemic Range in Chiapas, Mexico.

Vesicular stomatitis virus (VSV), comprising vesicular stomatitis New Jersey virus (VSNJV) and vesicular stomatitis Indiana virus (VSIV), emerges from its focus of endemic transmission in Southern Mexico to cause sporadic livestock epizootics in the Western United States. A dearth of information on the role of potential arthropod vectors in the endemic region hampers efforts to identify factors that enable endemicity and predict outbreaks. In a two-year, longitudinal study at five cattle ranches in Chiapas, Mexico, insect taxa implicated as VSV vectors (blackflies, sandflies, biting midges, and mosquitoes) were collected and screened for VSV RNA, livestock vesicular stomatitis (VS) cases were monitored, and serum samples were screened for neutralizing antibodies.

is not an arbovirus aficionado when feeding on cynomolgus macaques or squirrel monkeys.

Viruses transmitted by mosquitoes (e.g., dengue [DENV], Zika [ZIKV]) have demonstrated high potential to spill over from their ancestral, sylvatic cycles in non-human primates to establish transmission in humans.
