    Insights

    Parasitic infections, particularly Hymenolepis nana, are common in children with Phlyctenular keratoconjunctivitis. Male children aged 6-8 years and those from rural areas showed higher infection rates.

    Area of Science:

    • Ophthalmology
    • Infectious Diseases
    • Pediatrics

    Background:

    • Phlyctenular keratoconjunctivitis is an ocular inflammatory condition.
    • Parasitic infections are a potential contributing factor in pediatric eye diseases.

    Purpose of the Study:

    • To investigate the prevalence of parasitic infections in children with Phlyctenular keratoconjunctivitis.
    • To determine the relationship between parasitic infections and Phlyctenular keratoconjunctivitis in a pediatric population.

    Main Methods:

    • Microscopic examination of stool samples from 50 children diagnosed with Phlyctenular keratoconjunctivitis.
    • Data collection on patient demographics including age, sex, and geographic location (rural/urban).

    Main Results:

    • A 24% prevalence of Hymenolepis nana infection was detected.
    • Other detected parasites included E. hyistolytica (2%), Enterobius vermicularis (2%), Giardia lamblia (2%), and Tenia spp. (2%).
    • Male gender and age range of 6-8 years were associated with higher infection rates; rural children were more affected than urban children.

    Conclusions:

    • Parasitic infections, especially Hymenolepis nana, are significantly prevalent in children suffering from Phlyctenular keratoconjunctivitis.
    • Early diagnosis and treatment of parasitic infections may be crucial for managing Phlyctenular keratoconjunctivitis in children.

    Fungal Phylum Microsporidia

    Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

    Microbiome of the Eye

    The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

    Bacterial Phylum Chlamydiae

    The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

    Chronic Bowel Disorders: Introduction

    Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
    Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

    Microbial Interactions: Parasitism

    Parasitism is a form of microbial interaction in which parasitic microbes exploit a host organism for nutrients and shelter, often at the host's expense. Unlike mutualistic relationships, where both organisms benefit, parasitism benefits only the parasite and harms the host.Classification of ParasitesMicrobial parasites are broadly classified based on their location relative to the host.Ectoparasites remain on the host’s surface, such as the skin or outer tissues, drawing nutrients...

    Diversity of Protists II

    Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
