��: Adult hookworms reside in the small intestine of their hosts. Males measure approximately 8-12 mm long and are bursate, with two spicules that do not fuse at their distal ends. Females measure approximately 10-15 mm long. Adults of both sexes have a buccal capsule containing sharp teeth.

��: Infective, third-stage (L3), filariform larvae are 500-600 �m long. They have a pointed tail and a striated sheath. These L3 are found in the environment and infect the human host by penetration of the skin.

��: Rhabditiform (L1) larvae that hatch from eggs are 250-300 �m long and approximately 15-20 �m wide. They have a long buccal canal and an inconspicuous genital primordium. Rhabditiform larvae are usually not found in stool, but may be found there is a delay in processing the stool specimen. If larvae are seen in stool, they must be differentiated from the L1 larvae of Stronyloides stercoralis.

Ancylostoma duodenale

�� — Thu, 07 May 2009 03:26:57 +0300

�� : ��

��: Causal Agents: The human hookworms include two nematode (roundworm) species, Ancylostoma duodenale and Necator americanus. (Adult females: 10 to 13 mm (A. duodenale), 9 to 11 mm (N. americanus); adult males: 8 to 11 mm (A. duodenale), 7 to 9 mm (N. americanus). A smaller group of hookworms infecting animals can invade and parasitize humans (A. ceylanicum) or can penetrate the human skin (causing cutaneous larva migrans), but do not develop any further (A. braziliense, A. caninum, Uncinaria stenocephala). Occasionally A. caninum larva may migrate to the human intestine causing eosinophilic enteritis; this may happen when larva is ingested rather than through skin invasion. Eggs are passed in the stool , and under favorable conditions (moisture, warmth, shade), larvae hatch in 1 to 2 days. The released rhabditiform larvae grow in the feces and/or the soil , and after 5 to 10 days (and two molts) they become filariform (third-stage) larvae that are infective . These infective larvae can survive 3 to 4 weeks in favorable environmental conditions. On contact with the human host, the larvae penetrate the skin and are carried through the veins to the heart and then to the lungs. They penetrate into the pulmonary alveoli, ascend the bronchial tree to the pharynx, and are swallowed . The larvae reach the small intestine, where they reside and mature into adults. Adult worms live in the lumen of the small intestine, where they attach to the intestinal wall with resultant blood loss by the host . Most adult worms are eliminated in 1 to 2 years, but longevity records can reach several years. Some A. duodenale larvae, following penetration of the host skin, can become dormant (in the intestine or muscle). In addition, infection by A. duodenale may probably also occur by the oral and transmammary route. N. americanus, however, requires a transpulmonary migration phase. Geographic Distribution: The second most common human helminthic infection (after ascariasis). Worldwide distribution, mostly in areas with moist, warm climate. Both N. americanus and A. duodenale are found in Africa, Asia and the Americas. Necator americanus predominates in the Americas and Australia, while only A. duodenale is found in the Middle East, North Africa and southern Europe.

Crossing Over

�� — Sun, 19 Apr 2009 20:24:57 +0300

�� : ��

��: Another way meiosis generates genetic variability is through the process of crossing-over between maternal and paternal chromatid pairs during prophase I. If there are allelic differences between these segments, then the products of crossing-over are genetic recombinants for those alleles. The concept of crossing-over is explained in more detail in a discussion of Mendelian genetics in the Lab Simulations activity, Mendelian Inheritance.
