“…This study shows a high prevalence of lungworm in those provinces from which diagnostic information is available, consistent with the situation in neighboring countries, with similar climates, environments and pastoral animal management. For instance, in a study in Nangarhar, Afghanistan, 21.8% of 504 sheep examined in an abattoir were infected with lungworms [79], albeit the authors did not define the lungworm species. In Lahore, Pakistan, 31% of sheep and 11% of goats were found harboring lungworms, including D. filaria, P. rufescens, and M. capillaris [80].…”

“…Dictyocaulus filaria was also reported in 0.4% and 8.3% of sheep and goats, respectively, in the Chiltan National Park, Balochistan, Pakistan [81]. In Turkey, a relatively higher prevalence was reported in sheep, with 62.5% and 45.1% of animals testing positive in post-mortem and fecal examinations, respectively [79,82]. Regarding bovines, in neighboring Turkey, the prevalence of D. viviparus in cattle ranged between 0.3% and 70% [83], and in Faisalabad, Pakistan, the prevalence of D. viviparus infection in cattle and buffaloes was 4.8% and 5.1%, respectively [84].…”

Lungworms of the genera Dictyocaulus, Muellerius, Protostrongylus, and Cystocaulus are common helminths of domestic and wild ruminants with substantial veterinary and economic importance. Several studies have assessed the presence and prevalence of lungworm infections in ruminants in Iran. This report compiles the available scientific information about the occurrence of lungworms in domestic and wild ruminants in Iran between 1931 and June 2022 to give an insight into their epidemiology, and where possible to describe drug treatment efficacy. For this purpose, national and international scientific databases were searched. Overall, 54 publications comprising 33 articles in peer-reviewed journals, 8 conference papers, and 13 dissertations were evaluated regarding prevalence data; and an additional 4 peer-reviewed articles were evaluated regarding drug efficacy. Seven species of lungworms, namely Dictyocaulus filaria, Dictyocaulus viviparus, Dictyocaulus eckerti, Protostrongylus rufescens, Protostrongylus raillietti, Muellerius capillaris, and Cystocaulus ocreatus have been recorded from different ruminant hosts in Iran. Thirty-three studies conducted on small ruminant (sheep and goat) lungworms reported prevalences of lungworm infection of 11.6%, 45.81% and 66.29% using abattoir meat inspection, Baermann technique and fecal flotation, respectively. Eight studies conducted on large ruminants (cattle and water buffalo) reported prevalences of infection of 14.83%, 13.98% and 5% using abattoir meat inspection, the Baermann technique and fecal flotation, respectively. The prevalence of infection in wild ruminants was variable across examined species; 38% in urial, 37% in wild goats, 5% in goitered gazelles and 67% in red deer, in addition to a single case report in roe deer. There are few contemporary studies assessing the efficacy of currently available broad-spectrum anthelmintic compounds against lungworms in Iran. The high prevalence of multiple lungworm species in Iran, combined with a lack of information about drug efficacy, supports the need to improve the understanding of these important nematode parasites and inform the development of sustainable control strategies. The aim of this review and meta-analysis is to provide a baseline for future conventional parasitology and next generation molecular epidemiological studies of lungworm infection in pastoral ruminants in Iran.

“…En el caso de las cabras, los tratamientos incluyen imidazotiazoles [tetramisol (15 mg/kg) y levamisol (7.5 mg/kg)], benzimidazoles [mebendazol (15 mg/kg a 20 mg/kg)] y lactonas macrocícli-cas [ivermectina (0.2 mg/kg)] (Smith y Sherman, 2009;Engdawork, 2019). Para ovejas, se utiliza benzimidazoles [albendazol (7.5 mg/kg)] y lactonas macrocíclicas [ivermectina (0.2 mg/kg), moxidectina (0.2 mg/kg) y doramectina (0.2 mg/kg)] (Panuska, 2006).…”

La verminosis pulmonar en ovinos y caprinos es una de las parasitosis más importantes que afectan a ambas especies. Es causada por los nematodos Dictyocaulus filaria, Protostrongylus rufescens y Muellerius capillaris. El objetivo de este trabajo fue presentar información reciente sobre verminosis en ovinos y caprinos. Su patogenicidad depende de la cantidad de larvas presentes y su ubicación en el parenquima pulmonar, lo que puede provocar una bronconeumonía, que en ocasiones es mortal. La enfermedad puede ser clínica o subclínica, con signos como tos, taquipnea, secreción nasal y retraso en el crecimiento. El diagnóstico se puede realizar mediante detección de larvas del primer estadio (L1) en heces, utilizando la técnica de Baermann. Para el tratamiento se pueden utilizar benzimidazoles, lactonas macrocíclicas e imidazotiazoles. A pesar de la poca importancia que se le suele dar como verminosis pulmonar, puede provocar afectación a los parámetros productivos y disminuir la ganancia de peso, así como, predisponer a bronconeumonías secundarias, afectando la rentabilidad de las unidades de producción.
