Abstract This study aimed to evaluate the effects of autohemotherapy as an adjuvant in the control of gastrointestinal nematodes in sheep. Four experimental groups were formed: G1, 10 animals receiving autologous venous blood; G2, 10 animals receiving autologous venous blood and vermifuge containing levamisole; G3, 10 animals receiving only vermifuge containing levamisole; and G4, 10 animals as the control group receiving no treatment. We performed fecal egg count (eggs per gram, EPG) of strongyles, larval culture, hemogram, leukogram, and serum protein dosage prior to the start of treatment (D0), and on days 14 (D14) and 42 (D42). There was a significant decrease in the EPG of the groups receiving levamisole (G2 and G3) from D14 to the end of the experimental period. At the end of the evaluations, the mean EPG of G2 and G3 was significantly lower than that of G1 and G4. The most common nematode genus was Haemonchus (88%), and the least common was Trichostrongylus (1%). The Fecal Egg Count Reduction Test (FECRT) of G2 and G3 on D14 were 98.1% and 97.9%, respectively, however, in G1, the FECRT was zero on the two days when evaluation took place. G1 and G2 showed a significant increase in monocyte counts on D14 and D42. There was a significant increase in hematocrit and hemoglobin values in G2 and G3, however, a significant increase in the absolute value of red blood cells was observed only in G2. Two doses of autohemotherapy at 21-day intervals, administered alone or as an adjuvant to levamisole, is ineffective in controlling gastrointestinal nematodes in naturally infected sheep.

Forty-eight goats naturally infected with gastrointestinal nematodes were randomly divided into four groups (n=12): negative control (G1) (untreated), positive control (G2) (treated with doramectin, 1 mL/50 Kg b.w.), and G3 and G4 treated with 2.5 and 5 mg/Kg b.w. of a leaf aqueous extract ofCaesalpinia pyramidalis(CP). Fecal and blood samples were regularly collected for the evaluation of fecal egg count (FEC), hematological and immunological parameters to assess the anthelmintic activity. In treated animals with CP, there was noted a significant reduction of 54.6 and 71.2% in the mean FEC (P<0.05). An increase in IgA levels was observed in G3 and G4 (P<0.05), during the experimental period, suggesting that it was stimulated by the extract administration. In conclusion, the results showed that CP provoked a protective response in infected animals treated with them. This response could be partly explained by the CP chemical composition.

The aim of this study was to evaluate the anti-helminthic effect of a commercial formulation Bioverm® (Duddingtonia flagrans) in 28 sheep naturally infected with gastrointestinal nematodes. Animals were classified into two groups: G1 (n=14) treated with nematophagous fungi and G2 (n=14) untreated control. The efficacy of the anti-helminthic drug was assessed based on the egg count per gram of feces (EPG) of strongyles, larval culture, hemogram, leukogram, plasma protein levels, mucosal coloration using the FAMACHA© method, animals body weight, and evaluating the ocular mucosa for the FAMACHA© anemia guide were performed at days 0, 30, 60, 90, 120, 150, and 180. Additionally, the nematode larvae were quantified in the dry matter of the pastures of both groups. Results showed that the EPG was significantly decreased in animals receiving nematophagous fungi from D30 until the experiment end. The most common nematode genus was Haemonchus (63%), followed by Cooperia (23%) and Trichostrongylus (15%). Based on the fecal egg count reduction test (FECRT), treated animals showed a reduction of fecal egg count of 58.9%, 8.6, 92.8%, 96.4%, and 96.2%, at D30, D60, D90, D120, and D180, respectively. The absolute values of red blood cells and leukocytes were significantly increased at D60 and D90, respectively, in the treated animals. A significant weight gain was observed in the treated ewes at the end of the experiment; however, there was no correlation between the EPGs values and hematocrit with the FAMACHA© degrees of animals in both experimental groups. The mean EPG of both groups and the number of infectious larvae in the pastures were not directly proportional. In conclusion, nematophagous fungi contributed to decreased parasitic load in sheep, and consequently, improve animal performance; they can be a suitable alternative to reduce problems associated with nematode infections.

ABSTRACT. The efficacy and effective dose of bettlenut (Areca catechu) powder against gastrointestinal nematode worms was studied. Twenty five local goats at the age of 1 – 1.5 years of age weighing 8 to 12 kg were used in this study. All goat were naturally infected with gastrointestinal nematodes and they all had fecal egg count 3000/gram. The goats were randomly divided into 5 group: group I as a non treated control and group I, II, III, IV, and V were given bettlenut powder 5 gram, 10, 15 and 20 gram, respectively. The nematode worm were identified and grouped into family of Trichostrongylidae (Trichostrongylus sp. and Haemonchus sp.) and strongylidae (Bunostomum sp., Oesophagostomum sp. and Strongylus sp.).  in general, bettlenut powder in all doses is very effective against gastrointestinal nematode worms from both families compare to control group (P   0.01) and no significant different among administered doses (P  0.05). Bettlenut powder in all doses given is vey effective (P 0.01) against Trichostrongylus sp. and Haemonchus sp. from family of Trichostrongylidae. Bettlenut powder in all doses given is also very effective (P 0.01) against Bunostomum sp., Oesophagustomum sp. and effective (P 0.05) against Strongylus sp. from family of Strongylidae. The dose of 5 gram of bettlenut powder per goat is recommended for treating goat invested with gastrointestinal nematode worms because it is saver and can be given more than once.

Between June 1999 and August 2000, the effects of feeding medicated urea-molasses supplement blocks on the growth of dairy heifers in a marginal area of central Kenya were assessed by comparing the live-weight gain of supplemented and unsupplemented heifers grazing the same pasture. Thirty-nine heifers with an average age of 9.6 months were initially treated orally with albendazole (10 mg / kg body weight) and assigned to 3 groups : group I was fed urea-molasses blocks with incorporated fenbendazole (MUMB), group II was fed urea-molasses blocks (UMB) and group III heifers (control) received no block supplementation (NBS). Body weights of the heifers and faecal egg counts (FECs) were measured monthly and larval cultures were made of positive faecal samples of each group. The mean cumulative live-weight responses of the MUMB and UMB groups were significantly greater than the NBS group (P < 0.05). However, at the end of the experimental period, the mean weight gain of the MUMB group did not differ from that of the UMB group (P >0.05). The FECs were moderate to low in all groups and decreased progressively with increasing age of the animals; FECs for the urea-molasses-supplemented groups remained significantly lower than those of the NBS group throughout the experimental period (P <0.05). Haemonchus and Trichostrongylus were the predominant nematode genera found in the heifers, but Cooperia, Bunostomum and Oesophagostomum were also present. These results indicate that feeding of urea-molasses blocks substantially reduced production losses attributable to nematode infection of young grazing cattle, and confirms previous observations that well-fed animals are better able to overcome the effects of helminth infections.

The anthelmintic resistance in small ruminants is a common problem and concern worldwide. The aim of this study was to verify anthelmintic treatment efficacy in naturally infected sheep. This study was conducted on nine herds that used the same anthelmintic management for over a year. In each farm, the animals were divided into two groups: untreated control group (n = 5) and treated (n = 10) according to the number of eggs per gram of feces (EPG). The treatment effect was checked based on EPG results and larval culture performed before treatment and 10 days after treatment. Significant differences were not observed (P> 0.05) on EPG results between untreated and treated groups. The coproculture showed that the animals were infected primarily byHaemonchus spp., Trichostrongylus spp.,Teladorsagia spp., Cooperia spp. andOesophagostomum spp. In all farms, anthelmintic resistance by genera Haemonchus and Trichostrongylus was found, but this resistance varied greatly between farms.Haemonchus spp. showed resistance to closantel, levamisole, and albendazole. Trichostrongylus spp. was shown to be resistant to closantel, levamisole, and albendazole. The drugs tested showed to be efficient against the genera Teladorsagia,Cooperia, and Oesophagostomum. Based on these results, we conclude that the anthelmintic resistance to the tested drugs is a problem present in the farms evaluated.

PURPOSE: Evaluate the cardiovascular and hematological effects produced by chronic treatment with two dosis of etoricoxib in Wistar normotensive rats. METHODS: Thirty rats have been used and divided into one control group and two etoricoxib (10mg/kg and 30mg/kg) treatments groups for 60 days. The mean arterial pressure (MAP) was taken during the whole experimental period and at the end of this period, under anesthesia blood samples were taken, and further the withdrawn of the aorta, heart, brain, liver, and kidneys for the anatomopathologic study. RESULTS: The treatment with etoricoxib (30mg/Kg) produced a significant increase of the MAP from the 28th day of the experiment and from the platelets when compared to the control group and to the group treated with 10mg/Kg, besides producing a highly significant difference in hematocrit and in the red blood cells in relation to the control group. On the other hand the treatment with etoricoxib has not caused histopathological changes when compared to the control. CONCLUSION: These data show that the chronic treatment with etoricoxib leads to increase of the MAP, and to important hematological changes which seem to be associated to the hemoconcentration although not producing anatomopathological significant changes.

ABSTRACT: Given the numerous reports of anthelminthic resistance of sheep nematodes to different anthelmintic compounds, this study aimed to evaluate the resistance status of gastrointestinal nematodes from naturally infected sheep to monepantel in the state of Rio Grande do Sul. Four farms that present extensive raising system and absence of anthelmintic treatment for 60 days were selected for the study. Lambs that present counts of eggs per gram of feces (EPG) ≥200 (sensitivity of 50 EPG) one day (D-1) before the treatment were select for the study and randomly separated into two groups, a control group and an experimental group treated with monepantel. Feces were collected 9 days after the treatment (D+9) for EPG counts and fecal culture. The monepantel was 100% effective only on 2. The efficacy found on farm 1, 3, and 4 were 2.82%, 25.8%, and 78.4%, respectably. There were no viable larvae post-treatment at farm 2, but the genera Haemonchus, Trichostrongylus, Cooperia, and Strongyloides were resistant to it at the other farms. This study shows the presence of parasites resistant to the treatment with monepantel, pointing to the importance of monitoring its efficacy in sheep flocks of Rio Grande do Sul, Brazil.

120 selected layers (Bovans Goldline hybrid) aged 19 weeks with an average weight of 1 735 g were divided into two balanced groups: control group (Group C) and experimental (Group E). Layers were reared in three-tier cages with automatic watering, manual feeding, and at controlled light and temperature regimens. One cage accommodated two layers, the floor surface area was 0.1125 m<sup>2</sup> per layer. The experiment started after a 20-day adaptation period with layers aged 22 weeks (Week 22) and ended when layers were 68 weeks old (Week 68). In a period of initiation (i.e. Weeks 19–38), layers were fed the complete feeding mixture N1. Then they received the feeding mixture N2 until the end of the experiment. Feeding mixtures in both groups (C and E) had the same composition; the only difference between mixtures was that the feeding mixture in the experimental group was enriched with 1% clinoptilolite (i.e. the commercially available additive ZeoFeed). Layers received feeding mixtures and drinking water <I>ad libitum.</I> In the course of the experimental period, control layers laid 16 289 eggs while experimental layers laid 16 474 eggs. It follows from the results that the laying intensity in experimental layers was 1.7% higher as compared to control layers, i.e. the number of laid eggs in experimental layers increased by 5.6 eggs per layer. The mean weight of all laid eggs was 66.3 ± 6.25 g in the control group and 65.6 ± 5.44 g in the experimental group (<I>P</I> ≤ 0.01). Such performance was achieved at the consumption of feeding mixture being 141.7 g per laid egg in the control group and 137.6 g per laid egg in the experimental group. The consumption of feeding mixture in the experimental group was 4.1 g lower than that in the control group. The mean values of parameters monitored in blood plasma such as uric acid, cholesterol, glucose, lactose, calcium, phosphorus, ALP, and LDH in both groups of layers ranged within reference intervals, with no significant differences being detected between both groups.However, statistically significant differences between both groups were found in total plasma protein (<I>P</I> ≤ 0.01), triacylglycerol levels (<I>P</I> ≤ 0.05), and magnesium (<I>P</I> ≤ 0.01), which were elevated in the control group, and in AST (<I>P</I> ≤ 0.05) whose level in the control group was significantly lower than that in the experimental group. The results of haematological tests performed with layers’ blood revealed statistically significant changes in parameters such as the erythrocyte count (<I>P</I> ≤ 0.01), haemoglobin level (<I>P</I> ≤ 0.01), and MCHC (<I>P</I> ≤ 0.05), which were elevated in the experimental group, and in the leukocyte count (<I>P</I> ≤ 0.05), which was lower in the experimental group, as compared with the control. However, the values found varied within physiological ranges.

Background The appearance of anthelmintic resistance has made it difficult to control verminosis in sheep, leading to increased research to find alternative nematode control. The use of homeopathy in veterinary medicine has been studied as an alternative for the treatment and control of some diseases. In this study, ewes received an anti-parasitic homeopathic complex medicine during the critical peripartum period of increased susceptibility to nematodes. Methods Three randomized groups containing 16 animals each were assigned as follows: ‘H10’ received 10 g homeopathic complex added to concentrated food per day; ‘H20’ received 20 g homeopathic complex added to concentrated food per day; ‘C’ (control group) did not receive a homeopathic complex. Animals were tested to evaluate the effect of homeopathy on several health parameters during a period of 110 days. Results The parasite that prevailed in the copro-cultures of both treatments throughout the experiment was Haemonchus contortus (78.26%). Packed cell volume averages did not present statistically significant differences between the treatments (24.5, 24.4 and 23.9% to C, H10 and H20, respectively; p < 0.05). For total white cell count, lower mean values ( ±  standard error of mean) were observed for the H20 treatment (5,490.9 ± 0.02/µL; p < 0.05), whereas the H10 (5,919.4 ± 0.02/µL) and control (6,098.5 ± 0.02/µL) presented higher and similar averages (p > 0.05). The values for erythrocytes, monocytes, and lymphocytes did not show differences between treatments (p > 0.05). Body weight was greater in the H10-treated animals compared with control. For the fecal egg count (FEC) of Trichostrongylidae and Strongyloides spp., respectively, the averages of the H20 treatment (1,523.0 and 30.6) were not different from control (1,616.0 and 31.6) and H10 (1,038.0 and 27.6); for Trichostrongylidae, however, H10 presented a lower FEC than the control (p = 0.02). For Cooperia, H10- and H20-treated animals showed FEC reductions of 97% and 98%, respectively. Conclusions H20 treatment in peripartum sheep resulted in greater body weight and lower leukocyte count. H10 was associated with lower FEC for Trichostrongylidae. Both H10 and H20 justify a label of ‘effective anthelmintic’ for Cooperia.

The effect of barbados lilac (Melia azedarach, Linn., @100 mg/kg bwt. ), pineapple (Ananas comosus, Merr., @100mg/kg bwt.) and Benazol® (albendazole, @7.5 mg/kg bwt.) against natural gastrointestinal nematodes were studied in cattle. Their effect of TEC, Hb, PCV, TLC, ALT, AST and body weight were observed. Twenty four (24) naturally parasitized cattle of BAU Dairy Farm, Mymensingh were randomly divided into four groups, each consisting of six (6) cattle. Water extract of leaves of barbados lilac and pineapple were administered orally to the cattle of group A and B, respectively. Cattle of group C were treated with Benazol® orally. Cattle of group D was kept as infected control group. Fecal samples, body weight, hematological and biochemical parameters were examined before treatment and on 3rd, 10th, 17th and 28th day. A significant (p<0.01) reduction of EPG count was found following administration of barbados lilac (39.11-60.07%), pineapple (29.50-45.36%) and Benazol® (62.19-90.44%) in cattle. Whereas EPG increased significantly (p<0.01) in control group throughout the experimental period. After treatment with barbados lilac, pineapple and Benazol®, total erythrocyte count (TEC), hemoglobin (Hb) content and packed cell volume (PCV) were gradually increased significantly (p<0.01 and p<0.05) in cattle. Conversely, the total leukocyte count (TLC) were decreased significantly (p<0.01 and p<0.05) in treated cattle. The alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level were not significantly changed in the cattle. The body weight was increased significantly (p<0.01 and p<0.05) in barbados lilac, pineapple and Benazol® treated cattle.In contrast, body weight was decreased in control group. The present study reveals that water extracts of barbados lilac leaves were moderately effective and pineapple leaves were relatively less effective against mixed gastrointestinal nematode infections in cattle.DOI: http://dx.doi.org/10.3329/pa.v19i1.17107 Progress.
