Intestinal parasites in children with diarrhea in El Salvador.

In a study of parasitological prevalence in El Salvador, stool specimens of 210 children with diarrhea were examined for intestinal parasites. In 104 cases (49%), intestinal helminths and protozoa were found. 53.4% of the specimens showed single infestation, 31.7% showed double. 3% triple and 1% quadruple infestation. Of the helminths, 31% were Trichuris trichiura, 18% Ascaris lumbricoides and 5% Hymenolepis nana. Of the pathogenic protozoa, 7% were identified as Giardia intestinalis, 6% Entamoeba histolytica, 4% Cryptosporidium sp. and 3% Blastocystis hominis.

Brucellosis in the upper Nile region--Melut district, Sudan (report).

In the Melut district, South Sudan human and animal blood samples were investigated for Brucella abortus and Brucella melitensis. 9.2% of the investigated cattle and 16.2% of the green long-tailed monkies were Brucella abortus-positive. School children revealed a 3.7% positivity rate, Melut's hospital patients 5.2% and village children and adults 2.2%. However, only a small number of hospital patients was investigated. A small percentage of sheep and goats was investigated for Brucella melitensis revealing 12% positive results. 8.7% of cattle were positive. 2.2% of school children reacted in high titers against Brucella melitensis, 5.2% of Melut's patients and in the Melut district 3.6% of children and adults.

The importance of toilet facilities and their proper use by the population of Melut, South Sudan.

Particularly in recent years one has recognized the great importance of hygienic removal of faeces in the prophylaxis of intestinal infectious diseases and parasitosis. Numerous models have been carried out in various areas and the World Bank has financed its own projects for this purpose. The models however, had to be suited to each country and district and also the living habits and conditions of the ground-water etc. The often desired water flushing toilets (or even chemical camping toilets) from certain people in the developing countries are at present to be carefully considered due to the insoluble drainage and fresh water problems.

Serological examinations of HIV-I virus in Sudan.

1614 blood samples from men and women in the Upper Nile region, Melut district (southern Sudan) were examined for HIV-antibodies. 109 samples were positive twice in the ELISA test, and 18 (1.1%) were confirmed by the IFT and Western Blot test.

Serological screenings of various infectious diseases on the Cape Verde Islands (West Africa).

General screening investigations with various antigens were carried out with a view to further specific investigations being carried out on the Cape Verde Islands concerning infectious diseases. Serological positive reactions were found in Mumps, Adeno, PLT, Cytomegaly, Herpes, Para-influenza 1, 2, 3, Influenza A and B, Mycoplasmosis, RS-Virus, Gonorrhoea, Hepatitis A and B, R. conori, Malaria, Syphilis, Brucella abortus, Brucella melitensis, Varicella, Legionella, Picornavirus, Measles, German Measles, Listeriosis, Toxoplasmosis and Amoebic dysentery.

Serological investigations on the cause of diarrhoea on the Cape Verde Islands.

In the serological tests 45.9% of all samples reacted positive against rota virus. 20.8% of samples revealed Entamoeba histolytica positive sera, 25% Shigella flexneri positive sera, 12.3% Shigella sonnei and 13% Shigella dysenteriae positive sera. Campylobacter jejuni antibodies were found in 19% of samples, whereas 6.3% of sera reacted positive against Yersinia enterocolitica Type 3 and 4.8% against Type 9.

Investigations of wild animals as Leishmania reservoir in South Sudan.

In 1982-1983, 628 small mammals from around the so-called "kala-azar villages" in the Melut district and Paloich (Upper Nile region) were studied. A massive leishmania infection was found only in 1 jakal. All other attempts at isolation of an infectious agent were negative. To our knowledge, this is the first report of a jakal as a reservoir in the southern Sudan. In the Melut District (South Sudan) during the years 1982 and 1983, wild animals (small mammals) were investigated as reservoir of leishmania. Detailed studies have already been submitted by hoogstraal (1).

Investigations in the problem of diarrhoea in the Melut district, South Sudan (1981-1982).

Studies of diseases associated with diarrhoea in the Melut district of South Sudan in the years 1981-1982 showed amoebic dysentery and Rota-virus to be predominate, whereby according to our previous results Yersinia, Campylobacter, Shigella and Salmonella infections also play a role. In addition other parasitological bacterial and viral-infections are presumed.

The occurrence of leptospirosis in Iran.

The author examined 2,448 human and 541 domestic animal sera from Iran serologically for leptospira antibodies. Human sera revealed a 3.3% positivity rate in titer levels of 1:100 and higher, namely with the serovare of the serogroups Australis 2.3%, Sejroe 0.8%, Grippotyphosa 0.2%, Icterohaemorrhagiae 0.1%, Canicola 0.1%, Autumnalis 0.4% and Javanica 0.04%; domestic animal sera revealed a 6.8% in titers of 1:800 and higher, namely with Icterohaemorrhagiae 3.8%, Grippotyphosa 1.4%, Sejroe 1.2% and Bataviae 0.4%. The positivity rate for men was 3.1% for women 3.6%. In Teheran the seropositivity was higher--3.6% as in Rasth, the capital of the Gilan province--1.9%.

Cryptosporidiosis in Ogun State, south-west Nigeria.

During the period of one month in the rainy season in Ogun State in south-west Nigeria 479 stool samples (420 of which were diarrhoea stool samples) were examined for cryptosporidiosis. Oocysts were detected in 2.3% of all stools, in 2.6% of diarrhoeal stools and in 5.3% out of 150 children with diarrhoea. Cryptosporidium was the sole pathogen detected in six of 11 cases. In addition to cryptosporidia also Entamoeba histolytica, Blastocystis hominis, Giardia lamblia, Ascaris lumbricoides, and Trichuris trichiura could be found. Compared to other studies in tropical countries, the frequency of infection was lower in south-west Nigeria.
