Vertical Transmission, September 2012

Vertical Transmission of Bacterial Eye Infections, Angola, 2011–2012

To determine transmission rates for neonatal conjunctivitis causative microorganisms in Angola, we analyzed 312 endocervical and 255 conjunctival samples from mothers and newborns, respectively, during 2011-2012. Transmission rates were 50% for Chlamydia trachomatis and Neisseria gonorrhoeae and 10.5% for Mycoplasma genitalium. Possible pathogenic effects of M. genitalium in children's eyes are...

Rzeszow – Sofia September 2012

We consider queuing systems as models of distance learning system we analyze how characteristics of business process in the system affect on throughput and on learning outcomes. The processes of executing tasks and tasks validation process are the key processes in the distance learning. A model of the process performed by a student is a queuing system with refusals. A model of the process perfo...

Intrasperm vertical symbiont transmission.

Symbiotic bacteria are commonly associated with cells and tissues of diverse animals and other organisms, which affect hosts' biology in a variety of ways. Most of these symbionts are present in the cytoplasm of host cells and maternally transmitted through host generations. The paucity of paternal symbiont transmission is likely relevant to the extremely streamlined sperm structure: the head c...

[Vertical or circumstantial transmission?].

Si bien es una gran limitante el no haber realizado los exámenes complementarios mencionados (aislamiento viral, los hallazgos histopatológicos en la placenta), hubiese sido de gran valor el aislamiento del virus en aspirado traqueo-bronquial, ya que este es más específico (2). El hallazgo de un PCR positivo en un hisopado nasal dentro del contexto de una pandemia no necesariamente indica que e...
