First report of Thelazia sp. from a captive Oriental white stork (Ciconia boyciana) in Japan. (1/25)
Nematodes of the genus Thelazia were recovered from the cornea and inferior conjunctival sac of an immature Oriental white stork (Ciconia boyciana). The bird hatched and reared at the Toyooka Oriental White Stork Breeding Center, Hyogo Prefecture, Japan, but died of chlamydiosis. There were neither gross nor histopathologic ophthalmic lesions. The eye worm from a bird is believed to be first reported in Japan. As regarding reintroduction plan for the Oriental white stork, control measures for prevent further infection with the eye worm will be needed.

The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm. 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda in Korea. (+info)Human Thelaziasis occurrence in Taiwan. (3/25)
A 62-year-old woman presented with unilateral eye swelling and itching. Subsequent examination showed the cause was an infestation of the parasitic worm Thelazia callipaeda. The vector leading to human infection is the fly. The possible mechanisms of infection for this patient are discussed. Although this is a known form of ocular infection, especially in Asia, this is one of few reported cases in Taiwan. (+info)First Thelazia callipaeda infestation report in a dog in Taiwan. (4/25)
An ocular Thelazia callipaeda infestation was found in a male domestic dog in Taiwan during regular examination. This is the first report of the parasite from pet animal in Taiwan. The infested dog showed normal bodily condition but slight conjunctival congestion. This parasite has been reported in humans in southeast Asia, China and Korea. In 1998, first human case was reported in the central area of Taiwan. The dogs infected with T. callipaeda may have important implication in the infestation of this parasite to humans as reservoir hosts. (+info)Human thelaziasis, Europe. (5/25)

Small, white, thread-like, motile worms were recovered from the conjunctival sac of a 13-year-old girl and a 50-year-old woman from Dibrugarh district, Assam, India. They were identified as thelazia species. These two cases have been reported due to their rarity in India and elsewhere.

(+info)Thelazioidea is an order of parasitic nematodes, including the species Thelazia, which are known to infect the eyes of various mammals, including humans, by using flying insects as intermediate hosts for their life cycle.
Thelazioidea is not a medical term, but a taxonomic category in the field of biology. It refers to a superfamily of nematodes (roundworms) that includes the genus Thelazia. Members of this superfamily are known as "eyeworms" because they can infect the eyes of various animals, including humans.
Thelazia species are transmitted by flying insects such as flies, which serve as intermediate hosts for the parasites. The adult worms live in the conjunctival sac of the eye and feed on tears, causing symptoms such as eye irritation, tearing, and discharge. In severe cases, they can cause corneal ulcers or blindness.
While it is important for medical professionals to be aware of the existence of Thelazia species and other eyeworms, a specific medical definition of Thelazioidea does not exist.

Pinworm infection - Wikipedia
Pinworm infection spreads through human-to-human transmission, by swallowing infectious pinworm eggs.[18][19] The eggs are hardy and can remain infectious in a moist environment for up to three weeks,[11][18] though in a warm dry environment they usually last only 1-2 days.[20] They do not tolerate heat well, but can survive in low temperatures: at −8 degrees Celsius (18 °F), two-thirds of the eggs are still viable after 18 hours.[11] After the eggs have been initially deposited near the anus, they are readily transmitted to other surfaces through contamination.[19] The surface of the eggs is sticky when laid,[12][11] and the eggs are readily transmitted from their initial deposit near the anus to fingernails, hands, night-clothing and bed linen.[9] From here, eggs are further transmitted to food, water, furniture, toys, bathroom fixtures and other objects.[12][18][19] Household pets often carry the eggs in their fur, while not actually being infected.[21] Dust containing eggs can become ...
Swimmer's itch - Wikipedia
Swimmers itch, cercarial dermatitis or schistosome dermatitis is a short-term allergic contact dermatitis occurring in the skin of humans that have been infected by water-borne schistosomes, a type of flatworm. It is common in freshwater, brackish and marine habitats worldwide.[1] The incidence of this condition may be increasing, although this may be attributed to better monitoring and reporting. Nevertheless, the condition is considered to be an emerging infectious disease.[2] The main symptom is itchy papules (raised skin) that commonly occur within 2 days of infection. Initially, wheals develop quickly, then turn into maculae in about half an hour. Within 10-12 hours these turn into very itchy papules that reach their worst by the second or third day. The papules disappear in 1-2 weeks but secondary effects from scratching can continue longer. The intense itching, which peaks after 48-72 hours, is associated with pain and swelling of the affected areas.[3] People repeatedly exposed to ...

Cutaneous larva migrans - WikiProjectMed
The infection causes a red, intensely pruritic (itchy) eruption, and may look like twirling lesions.[4] The itching can become very painful and if scratched may allow a secondary bacterial infection to develop. Cutaneous larva migrans usually heals spontaneously over weeks to months and has been known to last as long as one year.[5] However, the severity of the symptoms usually causes those infected to seek medical treatment before spontaneous resolution occurs. Following proper treatment, migration of the larvae within the skin is halted and relief of the associated itching can occur in less than 48 hours (reported for thiabendazole).[2] This is separate from the similar cutaneous larva currens which is caused by Strongyloides. Larva currens is also a cause of migratory pruritic eruptions but is marked by 1) migratory speed on the order of inches per hour 2) perianal involvement due to autoinfection from stool and 3) a wide band of urticaria.[6] ...

Nematode - Wikipedia
Most nematode species are dioecious, with separate male and female individuals, though some, such as Caenorhabditis elegans, are androdioecious, consisting of hermaphrodites and rare males. Both sexes possess one or two tubular gonads. In males, the sperm are produced at the end of the gonad and migrate along its length as they mature. The testis opens into a relatively wide seminal vesicle and then during intercourse into a glandular and muscular ejaculatory duct associated with the vas deferens and cloaca. In females, the ovaries each open into an oviduct (in hermaphrodites, the eggs enter a spermatheca first) and then a glandular uterus. The uteri both open into a common vulva/vagina, usually located in the middle of the morphologically ventral surface.[49] Reproduction is usually sexual, though hermaphrodites are capable of self-fertilization. Males are usually smaller than females or hermaphrodites (often much smaller) and often have a characteristically bent or fan-shaped tail. During ...
