Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty Dec 2022

Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty

SURE Journal: Science Undergraduate Research Experience Journal

Background: The animal welfare and production consequences of gastrointestinal nematode infections, namely Nematodirus battus, on sheep are compelling. The control of gastrointestinal infections has been heavily reliant on the administration of anthelmintics since their introduction into mainstream use in 1960. However, their frequent and often excessive use has resulted in anthelmintic resistance being reported extensively in several gastrointestinal nematode species. The prevalence of anthelmintic resistance as well as the increase in the number of cases of multiple-drug resistance in nematode populations now poses substantial hindrance on the viability of sheep production systems. However, despite the threat N. battus poses …

The current study was conducted to determine the morphological, morphometric, and histological characteristics of bulbus oculi and lacrimal gland in sheep. For this purpose, 28 pairs (n = 7 males and n = 7 females) of bulbus oculi from Morkaraman and (n = 7 males and n = 7 females) Norduz sheep were analyzed. The bulbus oculi in the skulls were dissected from the orbit and removed. The morphometric data such as distance between endpoints of the dissected bulbus oculi in temporal, nasal, and dorsal directions, the length between endpoints of the pupil in dorsal and ventral directions, and as …


Some Hematological Parameters And Enzyme Histochemistry Of Peripheral Bloodleukocytes In Kivircik Sheep, Mehmet Faruk Aydin, İhsan Kisadere Jan 2022

Some Hematological Parameters And Enzyme Histochemistry Of Peripheral Bloodleukocytes In Kivircik Sheep, Mehmet Faruk Aydin, İhsan Kisadere

The aim of the present study was to determine some hematological parameters (RBC, WBC, HCT, HGB, MCH, MCHC, MCV, and PLT), the presence and percentages of ANAE and AcP-ase positivities in leukocytes and the differential leukocyte count in Kivircik sheep. Blood samples were taken from the jugular vein of 40 (rams = 20; ewes= 20) healthy, 1-year-old sheep. MCH and MCHC values were found statistically higher in rams than ewes (p < 0.05). Mean percentages of ANAE-positive PBL were defined as 74.16 ± 11.94% in ewes and 70.33 ± 8.39% in rams. It was not determined any significant changes according to sex. On the other hand, the percentages of ACP were determined as 67.12 ± 6.54% in ewes and 66.71 ± 6.58% in rams. It was not found any significant differences according to sex. For ANAE enzyme activity, lymphocytes, monocytes, neutrophils, and eosinophilic granulocytes showed a positive reaction. For ACP enzyme activity, although lymphocytes presented positivity, monocytes, neutrophils, eosinophils were negative. The ratio of lymphocyte, monocyte, neutrophile, eosinophile, and basophile of Kivircik ewes and rams were found as 64.35 ± 5.74%, 60.64 ± 8.85%; 3.41 ± 1.27%, 3.82 ± 1.42%; 27.58 ± 5.46%, 30.94 ± 8.71%; 2.41 ± 0.93%, 2.88 ± 1.45%; 1.76 ± 0.75%, 1.29 ± 0.58%, respectively. The difference between mean values was not found significant according to sex (p > 0.05). In conclusion, our study showed that enzyme histochemical methods can be used for identifying peripheral blood cells and can provide facilitates for early diagnosis of immune system-related disorders …

In this study, Akkaraman sheep and Hair goats raised extensively on the same farm were scored with the FAMACHA card. Score 1 was not present in both sheep and goats, whereas scores 5 and 2 were not detected in sheep and goats, respectively. While the number of animals with scores of 2, 3, and 4 was 9, 46, and 55 in sheep, the number of animals with 3, 4, and 5 scores in goats was 6, 55, and 41, respectively. In the study, the differences in the amount of RBC, Hct, and Hb in goats according to these score groups …
