Abstract Parasitic infection represents an emerging threat to wild ungulates and a challenge to their management. Although a lot of work has been carried out on helminth parasitic infestation of domestic ungulates of Kashmir but the data pertaining to this aspect of wild ungulates has being ignored. The study on gastrointestinal helminth parasitic infestation of wild ungulates was carried out during post livestock grazing period (November to May) of 2018/2019 in Hirpora Wildlife sanctuary (HWLS) to fill the gap in the existing literature. During the study fresh faecal samples of musk deer Moschus sp.(n=44) and markhor Capra falconeri (n=41)were collected and examined qualitatively and quantitatively for gastrointestinal helminth parasites. A total of seven helminth parasites were recorded which are arranged in the descending order of their overall prevalence as Haemonchus spp. (44.70%),Nematodirus spp. (40%), Trichuris spp. (37.64%), Strongyloides spp. (34.11%)Trichostrongylus spp. (28.23%),Monieziaspp. (23.52%) and Fasciola spp. (20%). The mean EPG (eggs per gram) of different parasites showed a considerable variation in both the wild ungulates. The highest mean EPGwas that of Haemonchus spp. and the lowest mean EPG was that of Fasciola spp. in both hosts. A statistically significant difference was observed in the mean EPG of different parasites among two wild hosts (t=3.606, p=0.01).

 A study was conducted to investigate the population density of helminth parasites in domestic ducks (Anas boschas domesticus) in relation to host's age, sex, breed and seasons of the year from March 2002 to May 2003. A total of 300 ducks were collected from different villages of Netrokona and Mymensingh districts of Bangladesh and autopsied to collect the parasites and counted to determine the population density of parasites. Off 300 ducks examined, 290 (96.66%) were infected with 17 species of helminth parasites in which 11 species were trematodes, 4 were cestodes and 2 nematodes. Among the parasites, density of cestodes was the highest (33.15±5.26), followed by trematodes (5.98±1.32); and nematodes (2.95±0.68). Mean density of parasites increased with the increase of age (young: 21.23±1.09, adult: 26.18±2.14 and old: 27.87±2.98) while the mean density of most of the helminth parasites was higher in female ducks (31.35±4.72) than in males (27.52±3.32). Indigenous ducks (33.72±3.61) were infected with the highest load of helminths than Khaki Campbell breed (29.61±4.32) of ducks. Mean density of most trematodes (5.42±0.80) were highest in winter season whereas mean density of all cestodes (48.43±4.85) and nematodes (4.13±1.76) were highest in summer.  The present study suggests that age, sex, breed of ducks and seasons of the year influence the parasitic infection to a greater extend.

AbstractSpiny mice,Acomys cahirinus dimidiatus, inhabiting the wadis close to St Katherine in the mountains of the Sinai peninsula, were trapped and their helminth parasites were studied. Sixty one mice provided faeces for analysis and 27 were killed and autopsied. Six species of helminths were recorded (the spirurid nematodes,Protospirura muricola(74.1%) andMastophorus muris(11.1%), the oxyuroid nematodes,Dentostomella kuntzi(59.3%),Aspiculuris africana(3.7%), andSyphacia minuta(3.7%) and the hymenolepidid cestodeRodentolepis negevi(18.5%)). The spirurids were the dominant species present, accounting for up to 0.87% of total host body weight. Analysis of worm weights and lengths suggested that transmission had been taking place in the months preceding our study. No sex difference in the prevalence or abundance of spirurids was detected. Significant differences were identified in the abundance of total nematode burdens and the mean helminth species richness between the three wadis which provided multiple captures of mice. There was also a marked effect of host age on both parameters. A highly significant positive correlation between spirurid egg counts and total worm biomass indicated that non-invasive techniques based on egg counts could be used to quantify worm burdens and when this technique was applied to a larger sample size (n= 61), a significant difference between sites but no host sex or age effects were detected for spirurid faecal egg counts. The data suggest that there are differences between helminth component communities infecting spiny mice in different neighbouring wadis, a hypothesis which will be explored further through our continuing studies in the Sinai.

Aim: The aim of the study is to identify helminth parasites in the gastrointestinal tract of Oreochromis niloticus in Dadin Kowa Dam, Yamaltu Deba Local Government Area, Gombe State. Study design:  Oreochromis niloticus fish species were randomly obtained from the local fishermen in the landing sites; between 7:00am-10:00am weekly. Place and duration of study: The study was carried out at Dadin Kowa Dam in Yamaltu Deba Local Government Area of Gombe State between the months of March to June, 2019. Methodology: 60 Oreochromis niloticus (Nile Tilapia) were obtained and examined for gastro intestinal parasites. Sex of the fish was determined by the presence and absent of an intromittent organ. The total length, standard length and body weight was measured using standard method. Dissection was done using standard procedure and the Parasites recovered were identified using the helminth parasites of fish identification guide. Results: Out of the 60 fish species examined. (23 female and 37 males), 21 (35.00%) were infected and were observed to habour six (6) endoparasites; viz nematodes, Cestodes and trematodes. The results show that there was a significant difference between infection rate, total length and weight of fish with female species having relatively higher percentage prevalence 11(43.50%) than the males 10 (29.70%). It was observed that the prevalence of parasitic infection increase with length and weight of the fish. Conclusion: Presence of these fish helminth parasites may lead to devaluation in protein constant in the body of the fish. The work therefore recommends water quality assessment of Dams as it is one of the factors that bring about the increase in parasitic infection.

BACKGROUND Echinococcus granulosis is a parasitic infection most commonly involving the liver. Iran is a hyperendemic area for this disease according to WHO. Despite improvements in medical and interventional radiological techniques, surgery remains the gold standard of treatment; however evidence on different surgical modalities were explained. Considering the high population of referring patients presenting to Omid and Ghaem Hospitals, Mashhad, Iran, we decided to compare the complications of our modified technique with routine technique in hydatid cyst surgery. METHODS 56 patients with hydatid cyst of the liver who underwent modified and routine surgical treatment in Ghaem and Omid Hospitals Mashhad, Iran were studied during Aug 2013- Nov 2015. 27 patients underwent modified surgical technique, whereas the remaining 27 patients were treated by using routine surgical method. These two groups of patients were compared with each other according to their postoperative length of hospital stay and resulting complications. RESULTS The mean age of our patients was 41 years. 27 patients were male and 29 were female. Our results showed no statistically significant difference regarding the incidence of postoperative complications between the two groups. However, mean length of hospital stay was significantly different between the groups (4.5 ± 1.87 and 7.6 ± 2.25 days, respectively, p < 0.001). CONCLUSION The method of modified surgery with closed cyst drainage, which does not use external drains, is a safe surgical modality in the treatment of hydatid cyst disease of the liver if applied properly on appropriate patients.

The prevalence of gastrointestinal helminth parasites and the gross pathological lesions produced by them in different types of poultry were studied from March 2005 to March 2006, in the Department of Parasitology, Bangladesh Agricultural University, Mymensingh. In this study, 240 viscera of three types of poultry such as broiler, layer and backyard indigenous chickens were collected from local markets of Mymensingh district. During routine examination, total six species of helminth parasites were recorded, of which three species were nematodes such as Ascaridia galli, Heterakis gallinarum and Capillaria annulata; two species were cestodes such as Raillietina tetragona and Amoebotaenia sphenoides and only one species was belonged to trematode such as Catatropis verrucosa. Prevalence of different species of gastrointestinal helminths was highest in backyard poultry (100%) followed by layer (48.75%) and broiler (3.75%) which was statistically significant (p < 0.01). Backyard poultry was significantly (p < 0.05) 168.21 and 4106.67 times more susceptible to helminth infection than layer and broiler respectively. But layer was 24.41 times more susceptible to helminth infection than broiler. In backyard poultry, all six species of helminth parasites were found. A statistically significant (p < 0.05) variation in the prevalence of the recovered parasites from backyard poultry were observed such as the prevalence of R. tetragona (100%) was the highest followed by that of A. galli (87.50%) and H. gallinarum (80%). From the odds ratio of the recovered parasites, it was observed that chance of developing R. tetragona (odds ratio 189.73) in backyard poultry was the highest followed by A. galli (odds ratio 7.51) and H. gallinarum (odds ratio 4.04). In case of layer, only A. galli and R. tetragona were recorded, of which, prevalence of A. galli was the highest (43.75%). In broiler, only A. galli (3.75%) was found. Gross pathological lesions were found only in backyard poultry. Pathological changes were detected in case of A. sphenoides and H. gallinarum infection. In A. sphenoides infection petechial hemorrhages were observed in the mucosa of the duodenum. On the other hand, tiny, white, circumscribed nodules of about 2-3 mm of diameter were found in the caecal mucosa in case of H. gallinarum infection. Results of the present study suggest that the backyard poultry is at the high risk of helminth infection. However, layers are also vulnerable to parasitic infection. So regular deworming is essential both in backyard poultry and layer birds to obtain better production from them.

Abstract Coprological studies on the prevalence of gastrointestinal helminth (GI) parasites in domestic ruminants from Srikakulam district of Andhra Pradesh, India, were carried out for a period of one year from January 2019 to December 2019. Fecal examination was done using direct smear, sedimentation and floatation methods. Altogether 3,527 fecal samples were examined including 595 from cows, 485 from buffaloes, 1342 from sheep and 1105 from goat. Out of 3,527 fecal samples examined, 1084 were found to be positive with three groups of gastrointestinal parasites (GI) showing an overall prevalence of 30.7%. Maximum infection was noted with nematodes (39.1%) and trematodes (37.3%), least infection was noted with cestodes (3.5%) and mixed infections were found to be moderate (20.01%). Host wise prevalence of parasitic infection has shown highest in the case of cattle recording 43.03%, followed by 40.8% in buffaloes, 29.4% in sheep, and 21.4% in goats. Total six varieties of parasites were recorded, the predominant being Haemonchus (Strongyle group) (29.25%), followed by Paramphistomum (25.5%), Fasciola (11.9%), Strongyloides (7.6%), Moniezia (3.5%) and Trichuris (2.2%). Season wise data on prevalence showed, high rate of infection in summer season (32.0%) when compared to winter (30.2%) and rainy (29.9%) seasons. Further studies are needed to design a rational for sustainable management of GI parasite infections in domestic animals of local regions.

Left ventricular function including regional wall motion (RWM) was evaluated by 99mTc first-pass and equilibrium gated blood pool ventriculography and glycohemoglobin (HbA1c) blood levels determined by a quantitative column technique in 25 young patients with insulin-dependent diabetes mellitus without clinical evidence of heart disease, and in healthy controls matched for age and sex. Phase analysis revealed abnormal RWM in 19 of 21 diabetic patients. The mean left ventricular global ejection fraction, the mean regional ejection fraction and the mean 1/3 filling fraction were lower and the time to peak ejection, the time to peak filling and the time to peak ejection /cardiac cycle were longer in diabetics than in controls. We found high HbA1c levels in all diabetics. There was no significant difference between patients with and without retinopathy and with and without peripheral neuropathy in terms of left ventricular function and HbA1c levels.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

SummaryFour thromboplastin reagents were tested by 18 laboratories in Europe, North-America, and Australasia, according to a detailed protocol. One thromboplastin was the International Reference Preparation for ox brain thromboplastin combined with adsorbed bovine plasma (coded OBT/79), and the second was a certified reference material for rabbit brain thromboplastin, plain (coded CRM 149R). The other two thromboplastin reagents were another rabbit plain brain thromboplastin (RP) with a lower ISI than CRM 149R and a rabbit brain thromboplastin combined with adsorbed bovine plasma (RC). Calibration of the latter two reagents was performed according to methods recommended by the World Health Organization (W. H. O.).The purpose of this study was to answer the following questions: 1) Is the calibration of the RC reagent more precise against the bovine/combined (OBT/79) than against the rabbit/plain reagent (CRM 149R)? 2) Is the precision of calibration influenced by the magnitude of the International Sensitivity Index (ISI)?The lowest inter-laboratory variation of ISI was observed in the calibration of the rabbit/plain reagent (RP) against the other rabbit/plain reagent (CRM 149R) (CV 1.6%). The highest interlaboratory variation was obtained in the calibration of rabbit/plain (RP) against bovine/combined (OBT/79) (CV 5.1%). In the calibration of the rabbit/combined (RC) reagent, there was no difference in precision between OBT/79 (CV 4.3%) and CRM 149R (CV 4.2%). Furthermore, there was no significant difference in the precision of the ISI of RC obtained with CRM 149R (ISI = 1.343) and the rabbit/plain (RP) reagent with ISI = 1.14. In conclusion, the calibration of RC could be performed with similar precision with either OBT/79 or CRM 149R, or RP.The mean ISI values calculated with OBT/79 and CRM 149R were practically identical, indicating that there is no bias in the ISI of these reference preparations and that these reference preparations have been stable since their original calibration studies in 1979 and 1987, respectively.International Normalized Ratio (INR) equivalents were calculated for a lyophilized control plasma derived from patients treated with oral anticoagulants. There were small but significant differences in the mean INR equivalents between the bovine and rabbit thromboplastins. There were no differences in the interlaboratory variation of the INR equivalents, when the four thromboplastins were compared.
