Strongyle infections in ponies. I. Response to intermittent thiabendazole treatments. (1/925)A group of seven ponies naturally infected with large numbers of small strongyles and raised under conditions to minimize reinfection were treated periodically over a three year span with thiabendazole at the rate of 44 mg/kg body weight. Based on the absence of worm eggs in the feces following each treatment, thiabendazole removed the adult strongyles present with a new population subsequently developing by maturation of inhibited larvae. It took as many as four or five treatments to eliminate or reduce significantly the worm burdens present in the ponies under the conditions of this study. Strongyle eggs started to reappear in the feces about six weeks after treatment and following the first treatment the mean egg counts rose to the pretreatment level. On successive treatments the interval for worm eggs to appear in the feces lengthened and mean egg counts never rose quite as high as immediate pretreatment levels. Hematological changes were not marked, although a small steady increase in the mean hemoglobin values and an equivalent small decrease in the mean eosinophil counts occurred in all ponies following each successive treatment. The study supports the rationale of regular anthelmintic treatment of horses in that even in the absence of reinfection, new burdens of adult worms develop following treatment. (+info)
Strongyle infections in ponies. II. Reinfection of treated animals. (2/925)Five of seven ponies whose strongyle worm burdens had previously been removed or markedly reduced by repeated thiabendazole treatments were reinfected with doses ranging from 100,000 to 500,000 small strongyle infective larvae. Reinfection of ponies resulted in the development of clinical signs characterized by abnormal feces, marked loss of weight and delayed shedding of winter hair coats. An abrupt increase in circulating eosinophils occurred during the first three weeks following reinfection. Patent infections developed in all ponies with worm eggs appearing in the feces from 12 to 15 weeks after receiving infective larvae. Worm egg outputs followed a cyclic pattern with approximately four to five peaks in egg output per year. There was an abrupt drop in the high worm egg counts in two untreated ponies approximately two and a half years after reinfection. No worms were recovered in the feces of these animals when they were subsequently treated, suggesting that a depletion in the number of inhibited larvae present in these ponies might have occurred.

Congenital transmission of Schistosoma japonicum in pigs. (3/925)Congenital transmission of Schistosoma japonicum in pigs was investigated by experimentally infecting sows at four weeks gestation (n = 3), 10 weeks gestation (n = 3), or a few weeks prior to insemination (n = 2). None of the piglets born to sows infected prior to insemination or in early pregnancy were found to be infected. However, all of the piglets (n = 26) born to sows infected at 10 weeks gestation were found to harbor schistosomes with S. japonicum eggs recovered from both their feces and livers. The findings show that congenital S. japonicum infection of pigs can occur if sows are infected during mid-to-late pregnancy and may have important implications not only for pigs but also for other mammalian hosts of schistosomes, including humans.

Enterotoxin-producing bacteria and parasites in stools of Ethiopian children with diarrhoeal disease. (4/925)Enterotoxinogenic bacteria were isolated from 131 (37%) of 354 Ethiopian infants and children with acute gastrointestinal symptoms. Only one of these isolates belonged to the classical enteropathogenic serotypes of Esch. coli. Two colonies from each patient were isolated and tested for production of enterotoxin by the rabbit ileal loop test, the rabbit skin test, and an adrenal cell assay. However, only 38% of the isolated enterotoxinogenic strains were Esch. coli; the others belonged to Klebsiella, Enterobacter, Proteus, Citrobacter, Serratia, and Aeromonas. In 18 patients both isolates were toxinogenic and belonged to different species. The incidence of intestinal parasites was 35% with no apparent correlation to the occurrence of toxinogenic bacteria in the stools. (+info)
Effects of in vitro culture methods on morphological development and infectivity of Strongyloides venezuelensis filariform larvae. (5/925)The effects of in vitro culture methods on morphological development and infectivity of Strongyloides venezuelensis filariform larvae (L3) to rats were investigated. A significantly higher body length was observed in L3 from filter paper culture (597.3 +/- 32.2 microns) than those in fecal (509.9 +/- 35.0 microns) and nutrient broth culture (503.3 +/- 31.0 microns) (P < 0.05). Larval infectivity was assessed by exposing rats to 1,000 L3 from each culture and worms were recovered from the lungs and small intestines. Recovery rate of these worms did not show any significant difference. A significantly greater body length of adults was recorded in those corresponding to the L3 harvested from filter paper (2,777.5 +/- 204.4 microns) and nutrient broth culture (2,732.5 +/- 169.8 microns) than those corresponding to the L3 obtained from fecal culture (2,600.5 +/- 172.4 microns) (P < 0.05). Although worm fecundity and EPG counts differed among culture methods but worm burdens and course of infection did not. These findings suggest that the methods of cultures have a significant effect on the morphological development of the larvae to the L3 stage, but do not influence the infectivity to rats. (+info)
Survey of Fascioloides magna in farmed wapiti in Alberta. (6/925)The formalin-ethyl acetate sedimentation procedure was used to detect ova of the giant liver fluke, Fascioloides magna, in feces of farmed wapiti in Alberta. Twenty (3.2%) of the 629 fecal samples examined contained ova of F. magna. Thirteen (33.3%) of the 39 farms surveyed had wapiti positive for F. magna. The presence of F. magna in farmed wapiti north of the North Saskatchewan River is confirmed, and 3 areas where the infection has become endemic are identified. (+info)
Independent evaluation of the Nigrosin-Eosin modification of the Kato-Katz technique. (7/925)A new modified quantitative Kato-Katz thick-smear technique for the detection of helminth eggs in faeces preserves hookworm eggs unaltered for a long time, while with the classic Kato-Katz technique, they disappear after approximately 2 h in tropical climates and thus slides must be read within hours after sample collection. For an independent comparison of these two laboratory techniques, faecal smears from 263 school children were examined in two surveys and prevalence, intensity of infection and costs of surveys calculated. There was no statistical difference between the methods in detecting prevalence and stratification of the sample in different classes of intensity. While there was no statistical difference for the arithmetic mean of the epg for T. trichiura and only a small difference for A. lumbricoides (P=0.04), we observed a highly significant difference for hookworm mean intensities of infections (P<0.001). From the public health viewpoint both methods provided similar results, but due to its simplicity and widespread use the classical Kato-Katz technique remains first choice for community investigation of soil-transmitted nematodes. However, the Nigrosin-Eosin approach has several advantages and can be a valuable alternative in certain circumstances. (+info)
Effect of anthelmintic treatment on sexual maturation in prepubertal beef heifers. (8/925)Heifers treated with ivermectin at weaning have been reported to reach puberty at a younger age and lighter weight than untreated heifers. We tested the hypothesis that heifers administered ivermectin would respond with earlier follicular development and a greater LH response to a 1-mg estradiol-17beta challenge (E2C) than untreated heifers. Fall-born Angus heifers (n = 32) were randomly assigned on 284 +/- 9 d of age (215.5 +/- 20.8 kg) to receive ivermectin (IVR) or albendazole (ALB), IVR + ALB, or to remain as untreated controls (CONT). Each group (n = 8) was housed separately in adjacent pens throughout the trial and managed to gain .8 kg/heifer on a ration containing 13.2% CP, 58.8% TDN, and 49.9% DM. The CONT heifers received an additional 2.27 kg/heifer of corn silage and 1.59 kg/heifer of corn daily to maintain ADG at comparable levels. Individual body weight was recorded weekly, and nematode eggs per gram (EPG) of feces were measured every 21 d. Ultrasonography was performed on alternate days starting 2 wk prior to E2C to characterize follicular wave patterns. Follicles were separated into classes (C1 [3 to 5 mm], C2 [6 to 9 mm], and C3 [10 mm]) and sizes (largest [LF], second [SLF], third [TLF], and fourth largest follicles [FLF]). The sizes of the regressing dominant follicle 1 (DF1) and the progressing dominant follicle 2 (DF2) were also determined. Serum concentrations of LH were determined from hourly jugular blood samples collected 8 to 24 h after injection of E2C. The IVR + ALB treatment group had more C3 follicles than ALB and CONT (P < .07). The IVR-treated heifers had larger TLF than ALB and CONT (P < .04). The IVR- and IVR + ALB-treated heifers had larger FLF and DF2 than ALB and CONT (P < .1). Least squares means for DF2 were 9.5 +/- .5, 8.0 +/- .4, 9.5 +/- .3 and 8.3 +/- .3 mm, for IVR, ALB, IVR + ALB and CONT, respectively (P = .02 for treatment effect). The E2C-induced serum LH concentration did not differ with respect to treatment. We conclude that heifers administered IVR display increased follicular development, supporting our earlier investigations regarding reduced age at puberty in heifers treated with IVR near weaning.

Efficacy of 3 anthelmintics in communally grazed sheep as reflected by faecal egg count reduction tests in a semi-arid area of...
ABSTRACT. A survey was conducted on the occurrence of anthelmintic resistance of nematodes in communally grazed sheep in a semi-arid area near Mafikeng South Africa, from January to March 2006. In the herds belonging to twelve smallholder sheep farmers, the efficacies of albendazole, levamisole and closantel were tested by faecal egg count reduction tests where 80 % efficacy was considered the cut off for anthelmintic resistance. The results of the faecal egg count reduction tests showed more than 80 % efficacy with all the drugs used in most cases, but there were notable exceptions. In 1 case, closantel had an efficacy of 72%, albendazole had an efficacy of 68 % and levamisole showed efficacies of 58%, 60% and 75 =% respectively on 4 farms. The occurrence of anthelmintic resistance in this farming sector is of concern and steps should be taken to prevent its further spread and development to avoid a situation developing as on numerous commercial sheep farms in South Africa where resistance is ...
PLOS Neglected Tropical Diseases: Sensitivity and Specificity of Multiple Kato-Katz Thick Smears and a Circulating Cathodic...
Author Summary Schistosomiasis is a parasitic disease infecting over 200 million people. It remains a major public health concern despite treatment of over 120 million people in sub-Saharan Africa alone. Accurate diagnostic methods are essential for monitoring drug efficacy and long-term control program success. The World Health Organization recommends two Kato-Katz thick smears (Kato-Katzs) from a single stool for Schistosoma mansoni diagnosis to map prevalence and areas for control interventions. Although highly specific, Kato-Katzs are thought to be insensitive at low egg counts. The recently refined urine point-of-care circulating cathodic antigen test (POC-CCA) has been proposed as a diagnostic alternative for mapping areas for interventions, and potentially for assessing drug efficacy. Over three years we assessed the accuracy of six Kato-Katzs and a single POC-CCA in detecting infections in Ugandan primary-school children at 11 time points with repeated praziquantel treatments.

A study on variation in immune responses and protective mechanisms to Ostertagia circumcincta and their relationship with...
The aim of this study was to examine the variation in immunological control of Ostertagia circumcincta, following natural exposure of sheep by grazing contaminated pasture, and relate this variation to that in parasitological parameters. Selection of sheep by faecal egg count resulted in different results in two consecutive years, in the first year those sheep with higher faecal egg counts had more adult female worms, in the second those sheep with higher faecal egg counts had longer, more fecund worms. These observations are consistent with earlier studies showing that faecal egg count is a function of worm burden and worm fecundity. Immunophenotyping of peripheral blood revealed that lymphocyte subset percentages are repeatable and that lymphocyte numbers were greater in grazing lambs. A negative association between worm burden and B cell percentage representation of peripheral blood lymphocytes was observed, possibly as a result of immune modulation, whilst immunophenotyping of cells from ...

Background Between 2013 and 2015 the Department of Agriculture, Food and the Marine (DAFM) administered a sheep technology adoption programme (STAP), with the aim of increasing profitability on Irish sheep farms by encouraging the adoption of best management practices. One of the options available to STAP participants was to test the efficacy of the anthelmintic treatment (benzimadazole, levamisole or macrocyclic lactone) used in their flocks by means of a drench test, which is a modification of the faecal egg count reduction test; individual faecal samples were collected from the same group of lambs before and after anthelmintic treatment, the number of eggs present pre and post treatment was subsequently determined from a pooled sample. Results In total, 4211 drench tests were undertaken by farmers during the 3 years of the programme. Information on the anthelmintic product used was available for 3771 of these tests; anthelmintics from the classes benzimidazole (BZ), levamisole (LV) and ...
Gastrointestinal parasitism is a widely recognised problem in sheep production, particularly for lambs. While anthelmintics have a pivotal role in controlling the effects of parasites, there is a paucity of data on how farmers use anthelmintics. A representative sample of Irish lowland farmers were surveyed regarding their parasite control practices and risk factors that may contribute to the development of anthelmintic resistance. Questionnaires were distributed to 166 lowland Irish sheep producers. The vast majority of respondents treated their sheep with anthelmintics. Lambs were the cohort treated most frequently, the majority of farmers followed a set programme as opposed to treating at sign of disease. A substantial proportion (61%) administered four or more treatments to lambs in a normal year. Departures from best practice in anthelmintic administration that would encourage the development of anthelmintic resistance were observed. In conclusion, in the light of anthelmintic resistance, ...
Fecal Testing in Horses/Parasite Control
When a veterinarian performs a fecal egg count (FEC) exam, they are looking to establish how many parasite eggs are present in each gram of manure tested--yielding a result called eggs per gram, or EPG. There are no universal standard EPG measures considered good or bad. However, traditionally a horse with an EPG value of 200 to 500 would be considered a candidate for treatment. In a herd, an average EPG value between all horses of 100 to 300 has long been considered the threshold between normal and unusual levels of parasite infestation. ...

Nutritionally-related blood metabolites and faecal egg counts in indigenous Nguni goats of South Africa
Introduction. The ever-increasing rural human population of South Africa, which has led to a shortage of grazing land, makes goat farming an alternative proposition (Mmbengwa et al., 2000). The Nguni is the major indigenous goat breed (Lehloenya et al., 2005) raised in the communal areas of South Africa. The Nguni goat is reputable mainly for its adaptability and resistance to diseases and parasites (Barry & Godke, 2001). It is, however, important to further understand factors that affect nutritional status of this genotype so as to generate reference values that can be used to monitor goat health. Although traditional methods such as live-weight, body condition scores (Ndlovu et al., 2007) and worm identification have been employed in the determination of the nutritional status of livestock, they lack accuracy (Schroder & Staufenbiel, 2006). Analysis of biochemical properties of goats, coupled with the traditional methods, is essential in diagnosing the various nutritional and metabolic ...
Anthelmintic-resistant nematodes in Irish commercial sheep flocks- the state of play | Irish Veterinary Journal | Full Text
Information on anthelmintic resistance was obtained using the following tests: FECRT and two in vitro MALDT tests, namely, a non-commercial MALDT and a commercial MALDT (DrenchRite®). For each of the studies, the farms involved were lowland farms each with a long-established sheep enterprise and a flock size greater than 100 ewes. Thus, they can be considered to represent the most committed participants in lowland sheep production.. The FECRT method was used to assess AR in flocks in three separate studies (the first FECRT study was undertaken in 2002 and included 11 farms (Co. Wicklow n = 7, Co. Monaghan n = 4) that were part of a collaborative project with Teagasc [8, 9]. The second study, undertaken in 2006, involved 7 farms (Co. Kilkenny) belonging to members of a sheep producer discussion group . The third, and most recent, study was undertaken in 2010, and included 3 farms that were participants in the Teagasc BETTER (Business, Environment and Technology through Extension and ...

Spring Survival Guide
Your horses egg-shedding score isnt an indication of how many parasites your horse has currently. Its simply reflective of how likely your horse is to shed parasite eggs in his manure, which will help you and your vet determine how often your horse needs to be dewormed in the future. If your horses fecal test comes back less than about 200 eggs per gram (of feces), then your horse is likely a low egg-shedder. If the results show more than 500 eggs per gram, then your horse is likely a high egg-shedder. If the results come in between 200 and 500 eggs per gram, then your horse is likely a medium egg-shedder ...

Streatham Hill Veterinary Surgery | Factsheet: Parasitic diseases in hamsters
Hamsters frequently harbor tapeworms within their small intestines. Heavy infections may cause weight loss, lighter infections however, usually go undetected unless pieces of the worms pass out of the hamsters anus or appear in the faeces.. People can become infected with the same organism and can be transmitted to uninfected hamsters (or people) when faeces harboring tapeworm eggs are inadvertently eaten. This underscores the importance of restricting access to hamsters and their enclosures by very young children. All such encounters should be carefully monitored. If you are suspicious of this parasite problem you should submit a faecal sample to your vet for analysis. The presence of tapeworm eggs in the sample (noted microscopically) confirms the diagnosis. Treatment for worms is possible and can be given by your vet. ...
What Constitutes a Proper Fecal Examination? - WSAVA2002 - VIN
There are many well-established techniques for recovering parasite stages from feces, ranging from those designed to recover specific diagnostic stages (the Baermann recovers only larvae), to concentration techniques designed to recover as many organisms as possible (flotation and sedimentation). There is, however, no single method that is 100% efficient for all parasite stages, and best results will be obtained by combining two or more techniques. As the zoonotic potential and public health significance of several organisms that commonly parasitize companion animals become more clearly appreciated, a strong argument must be made for reevaluating current veterinary methodologies in an effort to increase test sensitivity. A few relatively simple improvements to protocols for routine ova and parasite examinations will bring most private practices (and reference labs) up to a more acceptable standard.. 1. Always use fresh feces. Older feces may contain eggs, oocysts, and larvae that have developed ...

is usually a nematode with parasitic advancement exclusively in the tiny intestine of infected mice that induces a potent STAT6-dependent Th2 defense response. of contaminated mice showed how the local-tissue Th2 response was reduced in Se-deficient mice in comparison to that in Se-adequate mice. Furthermore, adult worms retrieved from Se-deficient mice got higher ATP amounts than worms from Se-adequate mice, indicating greater metabolic activity in the true encounter of the suboptimal Se-dependent local immune response. Notably, the procedure of worm expulsion was restored within 2 to 4 times after nourishing a Se-adequate diet plan to Se-deficient mice. Expulsion was connected with an increased regional manifestation of Th2-connected genes in the tiny intestine, intestinal glutathione peroxidase activity, secreted Relm- proteins, anti-IgG1 creation, and decreased worm fecundity and ATP-dependent metabolic activity. Intro Selenium (Se) can be a trace component with broadly differing degrees of ...

The repeatability of faecal egg counts, peripheral eosinophil counts, and plasma pepsinogen concentrations during deliberate...
Faecal egg counts, peripheral blood eosinophil counts and plasma pepsinogen concentrations were monitored during 2 successive, deliberate infections in 24 Scottish Blackface sheep. For all 3 techniques, the repeatability of replicate counts or of measurements made at short intervals were high which suggests that all 3 assays were reliable. Within an infection the repeatability of different samples from the same animal decreased as the interval between samples increased. The repeatability between infections was only moderate for faecal egg counts but high for peripheral eosinophil counts and plasma pepsinogen concentrations. Of the 3 variables, faecal egg count was the most strongly associated with the worm burden. Together, the three variables accounted for, in a statistical sense, one half of the variation in worm burden. The three variables, if measured concurrently, should provide a more effective identification of resistant and susceptible lambs. ...
Anthelmintic resistance in ovine gastrointestinal nematodes in inland southern Queensland - DAF eResearch Archive (eRABBB)
Objective To establish the prevalence of anthelmintic resistance in ovine gastrointestinal nematodes in southern Queensland. Design An observational parasitological study using the faecal egg count reduction test. Methods Sheep farms (n = 20) enrolled in this study met the twin criteria of using worm testing for drench decisions and having concerns about anthelmintic efficacy. On each farm, 105 sheep were randomly allocated to one of six treatment groups or an untreated control group. Faecal samples were collected on day 0 and days 10-14 for worm egg counts and larval differentiation. Single- and multi-combination anthelmintics, persistent and non-persistent, oral liquid or capsule, pour-on and injectable formulations were tested. Monepantel was not tested. Farmers also responded to a questionnaire on drenching practices. Results Haemonchus contortus was the predominant species. Efficacy ,95% was recorded on 85% of farms for one or more anthelmintics and on 10% of farms for six anthelmintics. No ...
Patterns of Schistosoma Haematobium Egg Distribution in the Human Lower Urinary Tract | The American Journal of Tropical...
Abstract Schistosoma haematobium egg burdens (eggs/g of tissue) of 17 anatomic segments of lower urinary tracts from 32 unselected Egyptian autopsies have been determined by tissue digestion and replicate counts of aliquots of the digestate. There were three anatomic patterns of egg distribution in these lower urinary tracts: apical, basal and diffuse. Regression of egg burdens of each of the anatomic segments as the dependent variable against egg burdens of the entire lower urinary burden yielded a good fit for 15 of 17 of these segments. Statistical analyses revealed that many of these equations for discrete anatomic segments can be combined, generally giving one equation for anatomic regions which are in continuity, indicating that the female worm lives and oviposits in specified venous plexes. These equations also suggest that there are differences in the rates, duration and onset of egg accumulation which may be responsible for schistosomal obstructive uropathy as a cause of death in fairly young
The American Journal of Tropical Medicine and Hygiene | Circulating Anodic Antigen (CAA) Levels in Different Age Groups in a...
Abstract A simplified version of the magnetic bead antigen-capture enzyme-linked immunoassay (MBAC-EIA) was used to detect circulating anodic antigen (CAA) in individuals of different age groups with Schistosoma haematobium infection only in an endemic area of Zimbabwe. An overall positive correlation between S. haematobium egg excretion and CAA levels was demonstrated. The age profile for CAA levels was generally comparable with the age profile of S. haematobium prevalence and intensity of infection. The CAA levels were higher in younger (5-14 years of age) individuals than in older (greater than 14 years of age) ones. Since the sensitivity of the MBAC-EIA in the diagnosis of S. haematobium infection was found to be 97%, CAA levels appear to be a useful indicator of worm burden in an endemic area.

Schistosomiasis is one of the most prevalent parasitic diseases and an important public health problem in many developing countries. In this era of global warming and climatic changes, the epidemiology of temperature-dependent infectious diseases could be changing implying the possibility of new transmission area in the world in general and in Ethiopia in particular. This study aims to assess the prevalence of Schistosoma mansoni infection and associated factors in irrigation workers in Gamo Gofa and South Omo Zone, 2017. Community based cross-sectional parasitological survey was conducted between March and June; 2017. Data were collected by using pre tested structured questionnaire and stool sample was collected from each participant for laboratory investigation. Kato-katz technique was used as recommended by World Health Organization for stool laboratory investigation to relevant variables.

Performance evaluation of existing immunoassays for Clonorchis sinensis infection in China | Parasites & Vectors | Full Text
Clonorchiasis ranks among the most important food-borne parasitic diseases in China. However, due to low compliance to traditional fecal examination techniques in the general population and medical personnel, immunodiagnosis is expected. This study evaluated, in parallel, the performance of four immunodiagnostic kits detecting clonorchiasis in China. A bank with 475 sera was established in this study. Except for the low performance of the kit detecting IgM, the other three kits detecting IgG showed sensitivities ranging from 81.51% (194/238) to 99.16% (236/238). Higher sensitivity was presented in heavy infection intensity [89.47% (68/76) to 100% (76/76)]. Among the four kits, the overall specificity varied from 73.42% (174/237) to 87.34% (207/237). It was observed that the specificity was lower in the sera of the participants living in clonorchiasis-endemic areas but without any parasite infection [67.5% (81/120) to 90% (108/120)], as compared to those from the non-endemic area [94% (47/50) to 98% (49
Effects of non-genetic factors on responses to gastro-intestinal nematode infections in Ethiopian sheep
The effects of non-genetic factors on responses to gastrointestinal nematode infections were examined in artificially infected indigenous Horro and Menz lambs in the central highlands of Ethiopia. The experiment involved lambs of two sexes, infection and monitoring regimens (3 levels), dam parity (4 levels) and birth types (2 levels). A total of 152 weaner lambs (103 Menz and 49 Horro) were used. Endoparasite challenge involved three infection periods (primary, secondary and tertiary) each separated by an anthelmintic treatment. Data were collected on faecal egg counts (FEC), packed cell volume (PCV), worm count, and weight gain. Female lambs were found to harbor lower numbers of T. colubriformis counts and had lower (p , 0.01) FEC in tertiary infection compared to males. Younger animals were more susceptible to the nematode infections than older animals as measured by all the parameters studied (p , 0.01). Twins had higher FEC in both secondary and tertiary infections compared to singles. Lambs ...

The findings of the present study on S. mansoni infection confirms the report of the previous reports in northwestern Tanzania [2, 3, 32], which demonstrated high prevalence of S. mansoni and infection intensity among adult population [2, 3]. Furthermore, our findings confirm high infection intensity among male individuals and young age groups [2, 3]. The variation in exposure to risk areas such as the lake and time spent in water sources (lake) partly explain the observed differences in prevalence and infection intensity between sex and between age groups [33-35]. In addition, a noted difference in prevalence of S. mansoni infection between villages was observed. Partly, this observation is explained by geographical location of the villages from the Lake Victoria shores, with Kayenze and Igalagala villages are located at the shoreline of the lake . The geographical variations of S. mansoni infection even in villages located in the same area have been noted elsewhere in Africa [6, 33, ...
Parasite Eggs Shed Light on Diseases During the Iron Age : Science : Nature World News
Iraq Academic Scientific Journals
Abstract. This study was carried out to estimate Calcium (Ca) and Magnesium (Mg) levels in the blood of lactating ewes infested with tapeworms in comparison with those of healthy sheep. Worms were diagnosed by microscopic examination of stool samples to identify eggs and adult worms. Blood and stool samples of twenty two lactating Awassi ewes (aged between 18-24 months) were collected; 12 samples represented positive infestation with tapeworms by clinical investigation, fecal egg count (FEC) and packed cell volume (PCV reported as percent). The results for blood packed cell volume of an individual ewe of this group fell below 20%, while (FEC) were above 1000 eggs per gram (epg), and 10 samples represented the control group whose fecal sample shows very low epg, while PCV was higher than 20%, with no clinical signs of parasitic infection. Tapeworms infestation in sheep causes a significant decrease in serum Ca levels, while no significant changes were observed in Mg level.. الهدف من هذه ...

Project : USDA ARS
An experiment is being conducted to identify unique genetic markers related to internal parasitism of small ruminants. Blood, tissue, and fecal samples are currently being collected from select populations of small ruminants with known parasitism history and/or expected progeny differences (EPD) for internal parasitism and growth traits. Genomic DNA will be purified from buffy coat or tissue samples and screened for single nucleotide polymorphisms in candidate genes. Genes will include cytochrome P450 3A family, and prolactin. In addition, plasma will be screened for unique microRNA populations. Identification of unique polymorphisms will be related to fecal egg counts (FEC), FEC EPDs, growth traits, and reproductive success using regression models and analysis of variance. A graduate student has been selected and is currently collecting data and will begin sample analysis in fall 2012. ...

Equine Endo - The scientific approach to animal welfare
Over many years horse owners world wide have blanket wormed there horses.. This however has had an impact on resistance. This is where a high population of worms in the horses gut has become resistant to the chemicals used in wormers, thus not killing the worms anymore and allowing them to continue there life cycle using your horse as their host, therefore your horse will not thrive and could become seriously ill. In severe cases it could lead to death.. By doing a egg count and finding out what epg (egg per gram) your horse has and identifying what type of egg. You can target worm and use the correct anthelmintics (wormers) accordingly.. IF your horse has less than 200epg you will not need to treat preventing unnecessary use of chemical wormers. Good for the animal and for your pocket. We do how ever recommend that you worm for encysted red worm as the larvae stages will not show up on a WEC the same goes for tape worm or you could test for tape worm using a Elisa blood test from your vet or ...
