Selamectin, a novel avermectin compound, was evaluated for its efficacy against naturally occurring infestations of Psoroptes cuniculi and Sarcoptes scabiei. A total of 42 New Zealand rabbits with psoroptic mange and 37 Angora rabbits with sarcoptic mange were used in the present study. On day 0, infested rabbits were treated topically with either selamectin at minimum dose of 6 mg kg(-1) (6-18 mg kg(-1) for New Zealand rabbits, n = 31 and 10-12 mg kg(-1) for Angora rabbits, n = 23) or vehicle only (control groups, n = 11 for New Zealand rabbits, n = 14 for Angora rabbits). The efficacy of selamectin was assessed both clinically and parasitologically by the presence or absence of viable mites. Rabbits were scraped for sarcoptic mites on days 7, 14, 28, 42 and 56 and had otoscopeic and/or microscopic examination for the detection of Psoroptes mites on days 7, 14, 42 and 56. Fisher's exact test was used to assess differences between the vehicle and selamectin treatment in the number of rabbits without mites (cure rates) on each assessment date. It was found that significantly fewer selamectin-treated rabbits had mites detected on skin scrapings (for S. scabiei) or otoscopeic and/or microscopic examination (for P. cuniculi) (P < 0.01) than the vehicle group. Results of the present study suggest that selamectin is effective against naturally infestations of P. cuniculi and S. scabiei in rabbits.

Objective. The purposes of this study were to determine whether secnidazole administered at a single dose of 10 mg/kg, orally, lessens or eliminates Giardia cyst shedding, and to validate the benefit of secnidazole treatment on clinical signs and faecal consistency in lambs naturally infected with Giardia duodenalis. Materials and methods. To this extent weaned 12 weeks of age lambs were selected and randomly assigned into two groups based on placebo (group C, n=7 untreated control group) or treatment (group S, n=10 lambs treated with a single dose of secnidazole at 10 mg/kg). Results. On days 0 and 10, before and after treatment, respectively, reduction in cyst excretion was determined. The faecal consistency and general health were recorded at each sampling day. Conclusions. During the study there was a high (99.98%) reduction in cyst excretion in the secnidazol treatment group compared to the positive control group on day 10, resulting in a significant (p<0.001) reduction, making secnidazole highly effective treatment option.Key words: Clinics, evaluation, lamb, secnidazol (Source: CAB). RESUMENObjetivo. El objetivo de este estudio fue determinar si la administración oral de una dosis única de secnidazol de 10mh/kg reduce o elimina la presencia de quistes de Giardia y validar el beneficio del tratamiento con secnidazol en los signos clínicos y la consistencia fecal de corderos infectados naturalmente con Giardia duodenalis. Materiales y métodos. Se seleccionaron corderos destetados de 12 semanas de edad que fueron asignados al azar a dos grupos con base a placebo (grupo C, n=7, grupo de control sin tratar) o tratamiento (grupo S, n=10 corderos con tratamiento de dosis única de secnidazol de 10 mg/kg). Resultados. En los días 0 y 10, antes y después del tratamiento, respectivamente, se determinó una merma en la excreción de quistes. La consistencia de la materia fecal y el estado general de salud fue registrado en cada muestreo diario. Conclusiones. Durante el estudio hubo una alta reducción en la excreción de quistes (99.98%) en el grupo tratado con secnidazol comparado con el grupo control positivo en el día 10, resultando en una disminución significativa (p<0.001), haciendo del tratamiento con secnizadol una opción altamente efectiva.

BackgroundThe objective of this study was to determine the effect of ketoprofen on acute phase protein (APPs) concentrations in goats undergoing castration. A total of 16 clinically healthy, male and 12 months old goats were enrolled and each case received ketoprofen (group I) or control (group II) in a randomized fashion. Goats were sedated with Xylazine-HCl, afterwards ketoprofen (3 mg/kg) was injected via jugular vein in group I, whereas physiological saline solution was administered to group II. Goats were castrated by the Burdizzo method. Hematological parameters were determined with a blood cell counter and plasma fibrinogen (Fb), serum haptoglobin (Hp), serum amyloid A (SAA) and ceruloplasmin (Cp) concentrations were measured Millars technique, ELISA kit or p-phenylenediamine oxidase activity prior to castration and throughout the study on 0 to 96 h.ResultsThere were no differences in pre-treatment serum Cp, SAA and Fb concentrations among the groups. Contrarily, there were significant differences in plasma Hp concentrations on 0 to 96 h onwards post-castration. There were no differences in WBC and PCV between groups. Cp, Fb, and SAA were almost constant or showed slight changes at various stages of the study with no significant differences between groups.ConclusionsThe results revealed that, levels of Cp, Fb and SAA may not be affected by castration such as the confounding parameters similarly to stress. More investigations possessing different surgical or non-surgical castration techniques with larger number of goats and focusing on specific markers for stress are suggested for precise analysis.

Giardia duodenalis (Giardia lambia, Giardia intestinalis), a flagellated parasite, is a gastrointestinal pathogen that affects public health worldwide. There are limited studies on the epidemiology and molecular characterization of G. duodenalis in farm animals in Turkey. Molecular characterization is requited to determine the zoonotic potential of Giardia infection. In the present study, 71 calf 50 lamb, and 66 fecal stool samples were obtained from the animal rectum using a disposable latex glove and the samples were transferred to the laboratory. Then, the presence of cysts was examined with a microscope using of saturated zinc sulfate flotation method (ZnSO4; 33%). Afterwards, the samples were scanned with ELISA-based rapid diagnostic test kits for diagnosis. Then, DNA was extracted with QIAamp DNA Stool Mini Kit (Qiagen, Germany). Nested PCR was then conducted with the corresponding primers. DNA sequence analysis was conducted on beta-giardin gene region of each PCR positive samples. Then, sequence analyses were blasted and compared with the access numbers in the gene bank (M36728 for sub-genotype A1, AY072723 for sub-genotype A2, for AY072724 sub-genotype A3, AY072725 for sub-genotype A3, AY072725 for sub-genotype B1, AY072726 for sub-genotype B2, AY072727 for sub-genotype B3, AY072728 for sub-genotype B4). In the microscopic examination, Giardia cysts were identified in 41 calves, 41 lambs, and 23 goats. Positivity was determined with rapid test kits in 38 calves, 16 lambs, and 26 goats. In nested PCR results, specific bands (511 bp) were obtained in 46 calves, 21 lambs and 24 goats. Sequencing findings demonstrated Assemblage A and subgenotype A3 presence in all animal samples. The importance of treatment and the need to take protective measures due to its zoonotic importance were emphasized.

The purpose of the present study was to evaluate the effect of chloroquine treatment on cyst excretion in calves naturally infected with Giardia duodenalis. The calves were randomly assigned into two groups based on placebo (group I, n=7 untreated control calves) or treatment (group II, n=7 calves treated orally with 2.5 mg/kg chloroquine twice daily for five consecutive days). The G. duodenalis isolates were identified by molecular characterization with β-giardin nested PCR and gene sequence analysis as assemblage A3. Cyst excretion was determined on days 0, 3, 7 and 10, before and after treatment. Geometric means of the number of excreted cysts did not change significantly in the control group during the trial. The reduction in cyst excretion after chloroquine treatment was 99% on day 3 and 100% on days 7 and 10. Chloroquine treatment is most probatly practically applicable, relatively inexpensive and highly effective against giardiosis in calves.

ÖZAmaç: Bu çalışmada Visseral Leishmaniasis'in (VL) farklı evrelerindeki köpeklerde oksidatif durum ve lipid profilinin araştırılması amaçlanmıştır. Yöntemler: Çalışmada VL'li 32, klinik, hematolojik ve biyokimyasal bulgulara göre sağlıklı 14 olmak üzere toplam 46 köpek kullanılmıştır. VL'li köpekler Leishvet grubunun sınıflamasına göre evre I (n=9), evre II (n=11), evre III (n=6), evre IV (n=6) olarak dört gruba ayrılmış ve sağlıklı kontrol grubu (n=14) ile karşılaştırılmıştır. Hayvanlarda serum lipid profili değerlendirmesi adına yüksek yoğunluklu lipoprotein (HDL), düşük yoğunluklu lipoprotein (LDL), kolesterol ve trigliserit, oksidatif durum analizi için ise toplam antioksidan kapasite (TAK), toplam oksidan seviye (TOS), paraoksonaz-1 (PON-1) değerleri incelenmiştir. Bulgular: VL'li köpeklerde, hastalığın tüm evrelerinde, sağlıklı gruptaki köpeklere kıyasla TOS değeri ve LDL konsantrasyonunda artış, PON-1 aktivitesi ve HDL konsantrasyonunda ise azalma belirlenmiştir (p<0,05). Gruplar arasında TAK değeri, kolesterol ve trigliserit konsantrasyonu açısından anlamlı bir fark bulunamamıştır. Sonuç: VL'li köpeklerde oksidatif stres ve lipid profilinde bazı değişiklikler gözlenmiştir. Hastalığın farklı evrelerindeki köpekler arasında ise önemli bir farklılık saptanamamıştır. VL'nin tüm evrelerindeki köpeklerde TOS değeri, PON-1 aktivitesi, HDL ve LDL konsantrasyonlarında belirlenen değişikliklerin hastalığın tanısında ve tedavinin planlamasında dikkate alınması gerektiği kanısına varılmıştır. (n=6), and stage IV (n=6); these dogs were compared to healthy control dogs (n=14). The lipid profile [high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol, and triglyceride levels) and oxidative status [total antioxidant capacity (TAC), total oxidant status (TOS), and paraoxonase-1 (PON-1) activity] were evaluated.Results: Compared to the control dogs, significant increases in the TOS and the LDL level and decreases in PON-1 activity and the HDL level were determined among the dogs at all stages of VL (p<0.05). No significant differences were found in the TAC and the cholesterol and triglyceride levels among the groups. Conclusion: Increased oxidative stress and alterations in lipid profile were observed among dogs with VL. However, no significant differences were detected between dogs at different stages of the disease. Therefore, changes in the TOS, PON-1 activity, and HDL and LDL levels in dogs at all stages of VL should be considered in the diagnosis of the disease and planning of the treatment.
