The pathogenicity of haemonchosis in sheep and goats in Iraq: 1. Clinical, Parasitological and Haematological Findings

A comparative study on clinical pathology changes in experimentally infected sheep with active and arrested larvae of Haemonchus contortus

“…These lambs suffered from a normocytic normochromic anaemia that is a common sign of chronic haemonchosis (Eslami 2006). The reduction of Hct and Hb is directly correlated with worm burden (Al-Quaisy et al 1987). The presence of a slight reduction in Hct and Hb in infected sheep by hypobiotic larvae is due to the majority of worm burden being L4 which has a small buccal capsule resulting in a negligible amount of haemorrhage (Eslami 2006).…”

Phytochemical Screening and Anthelmintic Evaluations of the Stem Bark of Afzelia Africana ?SM? (Keay, 1989) against Nippostrongylus Barziliensis in Wistar Rats

“…Parasitic nematodes are among the most common and economically important agents of infectious disease of grazing livestock, especially in small ruminants; in the tropics, subtropics and other parts of the world [1,2]. Livestock production in tropical climates suffers heavy economic losses due to gastrointestinal parasites [3,4]. The greatest losses associated with nematode parasite infections are sub-clinical, and economic assessment shows that the financial costs of internal parasitism are enormous [5,6].…”

Repercussão do tratamento contra verminose gastrointestinal sobre o quadro eritocitário e leucograma de ovinos com anemia verminótica

“…Existem diferentes tipos de hemoglobinas em caprinos e ovinos porém ainda não foi elucidada a influência desses tipos nas condições de saúde desses animais (BENESI, 1985). Um estudo verificou que a infestação de ovinos da raça Awassi com 500 larvas de Haemonchus contortus por kg de peso vivo provocava anemia a partir do décimo primeiro dia pósinfecção com redução do hematócrito inicial de 29,5% para 15,5%, no vigésimo dia após infestação (AL-QUAIZY et al, 1987). (FELDMAN, et al, 2000).…”
