This study was carried out during May-October 2010 to determine the prevalence of Cryptosporidium spp. in calves and children in rural areas around Mosul, north of Iraq. A total of 78 faecal samples were taken from calves which were no more than one year old. Information about age, consistency of faeces (as diarrheic or normal) and contact with human were recorded. At the same time, 95 stool samples were taken from children aged one month to 12 years old suffering from diarrhea and living in the same farms where the samples of calves have been collected. All samples were stained with modified Ziehl-Neelsen acid-fast stain and Auramine O techniques to detect the presence of Cryptosporidium oocysts. Results revealed that the prevalence of Cryptosporidium in calves and children were 43.56% and 18.9%, respectively. Comparison of results obtained with the two stain techniques showed no significant difference and being sensitive.

The prevalence of Cryptosporidium spp. infection in a cross-sectional study of dairy cattle, from two contrasting dairying regions in Tanzania, were determined by staining smears of faecal samples with the modified Ziehl-Neelsen technique. Of the 1 126 faecal samples screened, 19.7% were positive for Cryptosporidium spp. The prevalence was lower in Tanga Region than in Iringa Region. The prevalence of affected farms was 20% in Tanga and 21% in Iringa. In both regions, the probability of detecting Cryptosporidium oocysts in faeces varied with animal class, but these were not consistent in both regions. In Tanga Region, Cryptosporidium oocysts were significantly more likely to be found in the faeces of milking cows. In Iringa Region, the likelihood that cattle had Cryptosporidium-positive faeces declined with age, and milking cattle were significantly less likely to have Cryptosporidium positive faeces. In this region, 7% of cattle were housed within the family house at night, and this was marginally associated with a higher likelihood that animals had Cryptosporidium-positive faeces. Our study suggests that even though herd sizes are small, Cryptosporidium spp. are endemic on many Tanzanian smallholder dairy farms. These protozoa may impact on animal health and production, but also on human health, given the close associations between the cattle and their keepers. Further studies are required to assess these risks in more detail, and understand the epidemiology of Cryptosporidium spp. in this management system.

Introduction: Blastocystis spp. is a protist found in humans. Although usually the most frequent protozoa found in stool samples of both symptomatic and healthy subjects, its pathogenic or rather opportunistic role is yet to be clearly elucidated. To attempt to fill this gap, a cross-sectional study was conducted to compare the frequency of Blastocystis spp. in HIV positive (HIV+) versus HIV negative (HIV-) individuals in four health facilities of the Center Region of Cameroon. Methodology: Stool samples were collected from 283 HIV positive and 245 HIV negative subjects and analyzed using direct diagnostic tests. Results: A total of 46 (8.7%) individuals were found infected with Blastocystis spp., including 6.7% HIV positive and 11.0% HIV negative. This species was more frequent in urban and semi-urban areas than in rural areas, but evenly distributed among genders and age groups as well as among all sectors of activity. The prevalence of Blastocystis spp. (11.3%) was higher in HIV+ patients with a CD4 count ≥ 500 cells / mm3, but no significant difference was found among HIV clinical stages. Likewise prevalence, the mean number of cysts per gram of stool was similar between HIV positive and HIV negative individuals. People infected with Blastocystis spp. showed diverse clinical signs, but only flatulence was significantly more prevalent. The frequencies of these clinical signs were not related to HIV status. Conclusion: No clear relationship links the infection with Blastocystis spp. to HIV, although its presence was associated with digestive disorder, suggesting that this parasite might not be opportunist.

Cryptosporidium is an intracellular protozoan parasite and is increasingly gaining attention as a human and an animal pathogen, mainly due to its predominant involvement in worldwide waterborne outbreaks. This paper reviews the current knowledge and understanding of Cryptosporidium spp. in terrestrial and aquatic animals in Azerbaijan. The diagnosis of cryptosporidiosis relies on the identification of oocysts in faecal samples released by the infected host. Stool specimens were processed using the modified acid-fast staining method (Ziehl-Neelsen) and microscopically examined for Cryptosporidium oocysts. Thirteen species of Cryptosporidium (C. fragile, C. ducismarci, C. serpentis, C. varani, C. baileyi, C. meleagridis, C. muris, C. parvum, C. ubiquitum, C. andersoni, C. bovis, C. hominis, C. suis) from amphibians, reptiles, birds and mammals have been identified as a result of studies conducted between 1987 and 2019 on the structural features of Cryptosporidium oocysts in Azerbaijan territory.

A total of 622 fecal samples were collected from 3-30 days old calves, of both sexes. All samples were obtained from 3 groups according to stat of feces: Watrey diarrhea, pasty and normal, from May to December, 2000 in AL-Ishaki farms. Also, 400 stool samples from children at the age of 1-10 years suffered from watery diarrhea and 100 samples from workers in farms more than 20 years old, of both sexes, from December 2000 to May 2001. Two laboratory methods were used to identify Cryptosporidium oocysts: Modified Cold Ziehl Neelsen stain and flotation with sheather's solution. This study recorded a total rate of infection in neonatal calves 35.04%, with highest rate 53.80% in diarrheic calves and 27.62% in calves with pasty feces and lowest rate 16.45% in normal. Also recorded a highest rate of infection 45.56% in calves 3-7 days old and lowest 10% in calves 22-30 days old. In regarded to seasonal variation, the highest rate of infection recorded 54.94% in August and lowest 17.47% in July. This study showed that the sensitivity of Modified Cold Ziehl Neelsen diagnostic stain was very high 100% in comparison with flotation diagnostic method were the percentage of positive cases: 50.44%, 17.39% and 15.38% in the three groups of calves according to state of feces.  A total rate of infection in human (children and workers) was 12.4%, and according to ages, this study recorded highest rate of infection 17% in 1-<3 years, and lowest 6% in workers > 20 years old. According to seasonal variation 36.58% was the highest rate of infection in January. No significant difference recorded between both sexes, the rates of infection were 10.75% and 14.05% in female and male respectively.

Prevalence and molecular characterisation of Cryptosporidium species was done in kids belonging to organised and non-organised goat farms at Jabalpur. The overall prevalence of Cryptosporidium was 14.63%. The prevalence was non-significantly higher in male kids (16.16%) as compared to that of female kids (13.21%). Age wise prevalence was higher in kids up to one month age (16.13%) than that of kids upto 3 months age (13.99%). No significant difference was found in prevalence among different breeds and in kids kept in farm or field conditions. The prevalence was non-significantly higher in non-diarrhoeic kids than diarrhoeic kids. Most of the infections were of one score (76.6%). Molecular characterisation by PCR-RFLP of 18S SSU rRNA gene revealed presence of Cryptosporidium parvum species in positive faecal samples.

This study was carried out to assess the potential of animals, used for teaching and research, as a source of Cryptosporidium infection for students and staff of a University in Nigeria. Faecal samples from 185 animals reared on the teaching and research farm were collected and examined for Cryptosporidium spp. antigens by the use of an enzyme-linked immunosorbent assay (ELISA). From all the samples evaluated, 35.7% (66/185) were positive for Cryptosporidium spp. antigens with an infection rate of 30.6% (15/49), 40.7% (22/54), 43.9% (18/41) and 26.8% (11/41) for cattle, sheep, goats and pigs respectively. The rate of infection was significantly higher (p<0.05) in pre-weaned animals (63.6%) than in the post-weaned (23.6%) and adult (29.1%) animals. The infection rates, 54.8% and 42.3%, for diarrhoeic and female animals were significantly higher (p<0.05) than in non-diarrhoeic and male animals respectively. The presence of coproantigens of Cryptosporidium spp. observed in stool samples of ruminants and pigs suggests that these animals may be considered as a potential reservoir of this protozoa, that is able to contaminate the environment, infect other domestic and wild animals and in some cases humans.Keywords: Cryptosporidium, ELISA, Nigeria, Pigs, Ruminants

SUMMARYStools, known to have contained salmonellas were cultured in three enrichment media on arrival at the laboratory. The three media were laboratory prepared selenite F, laboratory prepared Muller-Kauffmann tetrathionate and commercially obtained Oxoid Muller-Kauffmann tetrathionate (CM343). Where faecal samples were sufficiently large, they were stored at room temperature and re-examined using the same three enrichment broths. Whether fresh or stored stools were investigated, the laboratory prepared media were significantly more efficient than the commercial medium. In a straight comparison of the two laboratory prepared media, no significant difference in efficiency was evident with fresh stool samples. With stored specimens, however, Muller-Kauffmann tetrathionate was significantly better than selenite F. This finding might be relevant in examining samples delayed in the post.

Abstract. Background: The invasive management of varicose veins has a known risk of post-operative deep venous thrombosis and subsequent pulmonary embolism. The aim of this study was to evaluate absolute and relative risk of venous thromboembolism (VTE) following commonly used varicose vein procedures. Patients and methods: A retrospective analysis of secondary data using Hospital Episode Statistics database was performed for all varicose vein procedures performed between 2003 and 2013 and all readmissions for VTE in the same patients within 30 days, 90 days, and one year. Comparison of the incidence of VTEs between procedures was performed using a Pearson’s Chi-squared test. Results: In total, 261,169 varicose vein procedures were performed during the period studied. There were 686 VTEs recorded at 30 days (0.26 % incidence), 884 at 90 days (0.34 % incidence), and 1,246 at one year (0.48 % incidence). The VTE incidence for different procedures was between 0.15–0.35 % at 30 days, 0.26–0.50 % at 90 days, and 0.46–0.58 % at one year. At 30 days there was a significantly lower incidence of VTEs for foam sclerotherapy compared to other procedures (p = 0.01). There was no difference in VTE incidence between procedures at 90 days (p = 0.13) or one year (p = 0.16). Conclusions: Patients undergoing varicose vein procedures have a small but appreciable increased risk of VTE compared to the general population, with the effect persisting at one year. Foam sclerotherapy had a lower incidence of VTE compared to other procedures at 30 days, but this effect did not persist at 90 days or at one year. There was no other significant difference in the incidence of VTE between open, endovenous, and foam sclerotherapy treatments.

SummaryIncreased thrombin generation occurs in many individuals with inherited defects in the antithrombin or protein C anticoagulant pathways and is also seen in patients with thrombosis without a defined clotting abnormality. Hyperhomocysteinemia (H-HC) is an important risk factor of venous thromboembolism (VTE). We prospectively followed 48 patients with H-HC (median age 62 years, range 26-83; 18 males) and 183 patients (median age 50 years, range 18-85; 83 males) without H-HC for a period of up to one year. Prothrombin fragment Fl+2 (Fl+2) was determined in the patient’s plasma as a measure of thrombin generation during and at several time points after discontinuation of secondary thromboprophylaxis with oral anticoagulants. While on anticoagulants, patients with H-HC had significantly higher Fl+2 levels than patients without H-HC (mean 0.52 ± 0.49 nmol/1, median 0.4, range 0.2-2.8, versus 0.36 ± 0.2 nmol/1, median 0.3, range 0.1-2.1; p = 0.02). Three weeks and 3,6,9 and 12 months after discontinuation of oral anticoagulants, up to 20% of the patients with H-HC and 5 to 6% without H-HC had higher Fl+2 levels than a corresponding age- and sex-matched control group. 16% of the patients with H-HC and 4% of the patients without H-HC had either Fl+2 levels above the upper limit of normal controls at least at 2 occasions or (an) elevated Fl+2 level(s) followed by recurrent VTE. No statistical significant difference in the Fl+2 levels was seen between patients with and without H-HC. We conclude that a permanent hemostatic system activation is detectable in a proportion of patients with H-HC after discontinuation of oral anticoagulant therapy following VTE. Furthermore, secondary thromboprophylaxis with conventional doses of oral anticoagulants may not be sufficient to suppress hemostatic system activation in patients with H-HC.

This study was carried out to investigate the epidemiology of Giardia lamblia parasites in patients who visited some of the hospitals in Anbar province, which included (Fallujah Teaching Hospital, Ramadi Teaching Hospital, Ramadi Teaching Hospital for Women and Children and Hit Hospital) during by examining 864 stool samples in a direct examination method, The results revealed the infection rate was 41.7 % and the percentage of infection among males 47.8% is higher than that of females 35.4% with significant differences (p≤0.05). The age groups (1-9) years recorded the highest rates 55.4% and the lowest rate 13.6% in the age group (40-49) years. The highest rate of infection was 62.5% during the month of June, while the month of October was the lowest rate 5% and significant differences. The incidence rate in rural areas was 50.6% higher than in the urban areas 32.5%. The study also included the effect of Teucrium polium L. on the parasite in the culture media HSP-1, the concentrations of 0.5-3 mg / mL significantly affected Giardia, it was noted whenever the greater the concentration, the greater the effect during different treatment periods (1-4) days, as the highest concentration 3 mg/ml killed all Giardia parasites on the fourth day of treatment.
