    Data were analyzed from 26,886 pregnancies to determine whether coitus is involved in the genesis of amniotic-fluid infections. The frequency of infection was 156 per thousand births when mothers reported coitus once or more per week during the month before delivery, versus 117 per thousand when no coitus was reported (P less than 0.001). The percentage of infected infants who died was 11.0 when there was coitus versus 2.4 when there was no coitus (P less than 0.001). The frequencies of low Apgar scores, neonatal respiratory distress, and hyperbilirubinemia were about doubled when mothers reported coitus. The coitus-associated effects were greater in preterm than in fullterm infants. The pregnancies in the study took place between 1959 and 1966, when national perinatal mortality rates were higher than they are now. Deaths from coitus-associated infections may be less frequent today.

    Fertilization01:38

    Fertilization

    During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
    Transcytosis of IgG01:15

    Transcytosis of IgG

    Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
    IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

    Sexually Transmitted Infections

    Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
    Development of the Oral Microbiota01:28

    Development of the Oral Microbiota

    The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

    Amebiasis

    Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
    Trichomoniasis01:18

    Trichomoniasis

    Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
