Parasitic infections are highly prevalent in many developing areas of the world and are common among pregnant women in developed countries. They may exacerbate maternal and fetal anemia, and contribute to low birth weight and poor infant survival. The placenta…
Toxoplasma gondii is a worldwide, intracellular protozoan parasite that can infect humans and almost all warm-blooded animals. Among the fetal and neonatal pathogens, T. gondii is certainly one of the most: ▪ Widespread, because it affects one third of the…
Human Papillomavirus Human papillomaviruses (HPV) are the most common cause of sexually transmitted infection in the United States, with approximately 14 million new infections annually, according to the Centers for Disease Control and Prevention (CDC). These DNA viruses are the…
∗ Drs. Louis Cooper and Charles Alford, Jr., previously contributed to this chapter. § References . ‖ References . The impact of rubella virus infection and the progress made toward controlling congenital rubella infection have been well chronicled. Rubella was…
The parvoviruses are a family of single-stranded DNA viruses that have a wide cellular tropism and broad host range, causing infection in invertebrate species and vertebrates, from insects to mammals. Although many parvoviruses are important veterinary pathogens, there are only…
Neonatal herpes simplex virus infection (HSV) was identified as a distinct disease in the 1930s. The first written descriptions of neonatal HSV were attributed to Hass, who described the histopathologic findings of a fatal case, and to Batignani, who described…
Knowledge about the hepatotropic viruses has grown dramatically in the past century, with contributions from clinicians, molecular virologists, immunologists, and pharmacologists. Hepatotropic viruses (hepatitis A through G viruses and torque teno virus [TTV]) are not a common cause of neonatal…
The enteroviruses, parechoviruses, and Saffold viruses are all members of the picornavirus family, a group of small, nonenveloped RNA viruses. Enteroviruses, including the polioviruses, coxsackieviruses, echoviruses, and numerically designated types, and parechoviruses constitute two distinct genera among the Picornaviridae, although…
Human cytomegaloviruses (HCMV) comprise a group of agents in the herpesvirus family known for their ubiquitous distribution in humans and in numerous other mammals. In vivo and in vitro infections with CMV are highly species specific and result in a characteristic cytopathology…
The viruses that cause varicella, zoster, measles, and mumps may complicate the management of a mother, fetus, or newborn when maternal infection with one of these agents occurs during pregnancy or at term. In the United States and other countries…
