Prevalence of ascariasis and ancylostomiasis in families: a collaborative inquiry.

A collaborative survey was carried out to estimate the prevalence of ascariasis and ancylostomiasis in random samples of 200 families in each of 3 different communities: a city slum (CS), an industrial township (IT), a farming village community (FVC). Stool examination was done by Kato's qualitative thick smear method. Ascariasis was prevalent in all the three communities; the percentage of families with multiple members infected varied from 50 to 91 per cent; the percentage of members infected within such a family varied from 48 to 74 per cent; the infection was highly prevalent (41-78%) in all age groups excepts adults in the IT. From 8 to 11 per cent of persons with ascariasis were negative on stool examination but passed worms after medication. Ancylostomiasis was arevelent mainly in the FVC and to a less extent in the IT; the percentage of families with multiple members infected was 83 per cent in the FVC and 17 per cent in the IT; the percentage of members infected within such a family was 54 per cent in the FVC and 58 per cent in the IT. All the persons surveyed received a single 10 mg/kg dose of pyrantel pamoate (Combantrin*, Pfizer) which was well tolerated.

[Relations between hepatitis B surface antigen and parasitic diseases: observations in patients with ancylostomiasis and schistosomiasis].

Hepatitis B antigen carriage was studied in Somalia in 155 patients with ancylostomiasis, with urinary schistosomiasis and with leprosy (lepromatosus and tuberculoid type and leprosy with schistosomiasis). The results have showed a significantly (p less than 0,001) higher frequency of HBsAg among the patients with ancylostomiasis (33,33%) and with urinary schistosomiasis (25,92%) than either the leprosy patients (9,67% in the L type and 6,89% in the T type) or the controls (11,11%); in the leprosy patients with schistosomiasis the frequency was 40,0%. The role of some penetrating skin parasites in the epidemiology of hepatitis B was discussed.

Eosinophilia in murine ancylostomiasis.

Eosinophil changes in the peripheral blood of singly and repeated infected mice were studied during murine ancylostomiasis. In singly infected animals, eosinophils began to rise on 1st day, reached a peak on 4th day and progressively declined from 9th to 30th day. In repeatedly infected animals, peak eosinophilia was observed during 3rd week of post infection and sustained upto 30th day with a slight decrease. These studies demonstrate that eosinophilia is induced due to antigen-antibody reactions in the host system and eosinophilia in helminthic infections is amnestic response.

Some histopathological and histochemical aspects of human ancylostomiasis.

Using Watson's intestinal capsule small intestinal mucosal biopsies were taken from 30 patients with parasitologically proved pure ancylostomiasis and 12 normal controls. Biopsies were examined pathologically and histochemically for the enzymes, Alkaline phosphatase, succinic dehydrogenase, non specific esterases and acid phosphatase. The study revealed normal histological as well as normal enzymatic activity of the intestinal mucosa.

[Ancylostomiasis].

Ancylostomiasis, i.e., infestation by Ancylostoma duodenale or Necator americanus, involves several thousands of subjects every year throughout the world and especially in tropical and subtropical regions where it is endemic. In Italy, after a severe epidemic during the construction of the St. Gotthard tunnel in the 1880s, and after a period of endemic infestation limited to some areas (1955-60), the last few years have witnessed a marked drop in the incidence of this disease which is nevertheless relevant in that it involves certain groups with occupational risk (farmers, miners, workers in clay quarries, etc.) and certain geographic areas of our country where inadequate hygienic behavior still persists among the rural population. After up-dating the epidemiology of the infestation, the authors review the principal prophylactic and therapeutic measures available.

Rejection of worm load through singly and repeatedly sensitized peritoneal exudate cells during experimental ancylostomiasis.

Sensitized peritoneal exudate cells from Swiss albino mice donors infected with a single dose of 1000 A. caninum larvae could expel a challenge dose of 500 larvae from recipients at a faster rate when compared to cells from repeatedly infected (250 + 250 + 500) donors. However, at 36 h after challenge, the larval expulsion was almost the same in both the groups. Because of the bowel sensitization by the cells, some larvae (not expelled) in the 1st group, readily migrated into muscles where they met allergic immobilization and death due to infiltration of inflammatory cells and their exudates at these sites.

Studies on experimental ancylostomiasis: transfer of acquired immunity to Ancylostoma caninum in mice through sensitized thymus and bone marrow cells.

An attempt has been made to transfer acquired immunity to Ancylostoma caninum infective larvae from infected Swiss albino female mice to nonimmune, isologous recipients of same sex, through immunized thymus and bone marrow cells. Immunized cells from donors infected with a single high dose of 1000 larvae were found to be more immunocompetent than cells from donors infected with a single, but low dose of 500 larvae.

Intestinal mast cells during experimental ancylostomiasis.

The alterations of mast cell counts induced in the gut of swiss albino mice by infection with Ancylostoma caninum larvae have been studied, both in single and multiple infections. It was found that mast cell rise was greater in females than males. In singly infected animals, mast cell increase was influenced by the infective dose of inoculated larvae. In case of repeatedly infected mice, mast cell counts were decreased because of their earlier degranulation.

[Uveitis in ancylostomiasis].

A 42-year-old patient from Sri Lanka presented with unilateral panuveitis. The only possible cause detected was ancylostoma duodenale, a parasitosis occurring frequently on the Indian subcontinent. The link between this and uveitis, and the therapeutic consequences, are discussed.

Ovicidal effects of albendazole in human ascariasis, ancylostomiasis and trichuriasis.

Albendazole, a broad spectrum anthelmintic, was administered as a 400 mg single dose to 20 patients harbouring Ascaris (ten cases), hookworms (four cases each of Ancylostoma duodenale and Necator americanus) and trichuriasis (ten cases). Faeces were obtained before treatment and during the following five days. Coprocultures were made for 90 days for Ascaris and Trichuris eggs, hookworm eggs were cultured by the Harada-Mori technique for at least eight days. Albendazole was ovicidal against all four genera of nematodes.
