Opis:
Trophozoites of Balantidium coli were isolated from the pig's caecum and cultivated in vitro. Pigs were divided into two groups: one with the acute balantidiosis and the second - with the asymptomatic balantidiosis. In the first case the biotic potential of protozoans turned out to be higher (the most intensive divisions occurred 24 hours after the second passage). Protozoans isolated from pigs with the asymptomatic balantidiosis had lower biotic potential (the most intensive divisions occurred 24 hours after the third passage). This fact indicates the differentiation of the investigated populations of B. coli.

Opis:
Animals with diarrhoea caused by Balantidium coli were investigated. The results of estimation of pH in the caecum content show the marked concentration of H+ ions (pH 5.1-6.0). Changes in pH of the parasite environment can abate enzymes activity, which can initiate compensatory reactions of the parasite, among others - intensification of excretion, cytotoxic for the host's tissues.

Opis:
cDNA encoding Ancylostoma ceylanicum cysteine protease (ACEY-1) was cloned into pGEX-4T eucaryotic expression vector then E. coli BL2 cells were transformed with the plasmid using electroporation method. The expression of the recombinant protein in liquid cultures was induced by the addition of IPTG. The Western blot analysis showed that the recombinated ACEY-1 may be solublised only partially at pH 7.4 which allowed affinity — purification of this protein using glutathione-sepharose column.

Opis:
This cross-sectional study was carried to determine the prevalence of intestinal parasitic infections among mentally handicapped individuals in Alexandria, Egypt, in the period from December 2012 till November 2013. The study was conducted on 200 institutionalized and non-institutionalized mentally handicapped individuals. Fresh stool samples were subjected to different stains including; trichrome for detecting intestinal protozoa, modified acid fast stain for intestinal coccidia and quick hot gram chromotrope stain for Microsporidia. Also they were processed by Kato-Katz and formol ethyl acetate techniques for intestinal helminths. Additionally, blood samples were collected for measuring hemoglobin levels. Out of 200 mentally handicapped individuals, 87 (43.5%) were infected. The infection rates were 44.6% and 42.6% for non-institutionalized and institutionalized people, respectively. Regarding gender, 46.7% and 38.5% were reported for the males and females respectively. The most common parasites detected were: Cryptosporidium sp. (23.5%), microsporidia (15%), Giardia lamblia (8.5%), Dientamoeba fragilis (8%), Cyclospora cyatanensis (7.5%), Blastocystis hominis (6.5%), Entamoeba histolytica (5.5%) and Entamoeba coli (2.5%). Rates for Isospora belli and Enterobius vermicularis were estimated to be 1.5% for each, while lower rate was reported for Iodamoeba butschlii (1.0%). Prevalence of infections among mentally handicapped individuals are indications for several risk factors, including improper sanitary hygiene and illiteracy about personal hygiene. Therefore, frequent investigations, health care and medical intervention are needed.

Opis:
The authors have examined 31 children from the nursery, out of which 8 children were positive, and 16 employees, out of which 3 persons were positive. They also wanted to examine the family members of positive children and positive employees, however the offer was accepted only by one cleaner´s family (infected with Ascaris lumbricoides, Enterobius vermicularis and Entamoeba coli). All the 8 members of this large family except of a cleaner (member of the family 1 = fm 1) and her grandson (fm 4) were without clinical and laboratory findings. They have formed 3 independent families living in 1st category flats. At that time a sewage disposal breakdown took place at the ground floor flat owned by the family number 2, and the flat was flooded by the sewage. All adult members of the families as well as the members of the family number 4 being the friends of family number 2 worked on flat cleaning. As the clinical symptoms showed later, during the prepatent period and just after its burning out (within 73–78 days), laboratory findings in members of the families proved that this event resulted in a heavy family infection equal to a family epidemic of intestinal parasites. The species Ascaris lumbricoides was diagnosed in 8 members (61.5%) of involved families and Giardia intestinalis in 7 members (53.85%). The species Enterobius vermicularis was found in 2 and Etamoeba coli in 1 member of the involved families. The family epidemic proved several times more frequent incidence of Ascaris lumbricoides and Giardia intestinalis than sporadic findings in children and adults. The fact that, after long years of low prevalence of Ascaris lumbricoides such a mass infection has happened can be treated as a surprise. And the same concerns Giardia intestinalis. The authors discussed the incidence of Ascaris lumbricoides and Giardia intestinalis and preventive measures taken against them in the population.

Opis:
The aim of the study was to present the past and actual prevalence of Entamoeba histolytica and other intestinal protozoa in Poznań Province. Although in Poland there are only few accurate data concerning the prevalence of intestinal protozoa, the results of some studies were found reliable. In a survey conducted in 1958 in an orphanage in Poznań (Kasprzak and Karlewiczowa) the intestinal protozoa were found with high prevalence (Table 1). After six years this prevalence decreased considerably (Karlewiczowa and Kasprzak, 1964). Because at the same time such a decrease in intestinal protozoa prevalence, especially that in Entamoeba coli, was observed in the whole population of the Poznań Province, long-term surveys were undertaken. The diagnosing of intestinal protozoa in faeces of 4165 persons, performed at more points in time in the period of 1963 to 1986 in the Poznań Province, were conducted by the same highly skilled staff. Decreasing rates of infection were seen for each amoeba species at nearly each point in time, particularly in the first eight years of observation (Table 2). By using the "amoebic index" and "amoebic prevalence rate" in assessing epidemiological factors (acc. WHO, 1969), the considerable reduction in both indices should be accounted for the improvement of the sanitation and socio-economic status in our country. After the Second World War some Polish authors expressed the fear that after returning to the country, the Polish soldiers who had fought in the endemic regions of invasive amoebiasis, infected with E. histolytica, would constitute sources for spreading amoebiasis and that the disease would be a nucleus of a new, hitherto unknown, social calamity in Poland. Fortunately, the fear did not come true. Although in this country the infection with amoebae, also with E. histolytica, decreased considerably after several years, unfortunately, some opinions still prevail, being the source of an amoebo-mania in the medical staff and corresponding amoebophobia in the patients.
