“…The few previous data available in Italy seem to be in line with the results obtained in other European countries, since a higher prevalence of small strongyles in respect to that of large strongyles was reported from southern and northern Italy [22,24,43], while in a donkey farm in central Italy a high prevalence of cyathostomins (>90%) was evidenced [23].…”

Intestinal strongyles are common helminths of donkeys, in which they may be responsible for disease and poor performance. This study aimed to identify intestinal strongyle genera in 55 naturally infected donkeys from three different farm typologies in Tuscany, central Italy, using morphological and metrical analysis of third stage larvae (L3) obtained from faecal cultures. Larvae were identified using two previous reported morphological identification keys. Moreover, eggs per gram (EPG) data were also evaluated to assess differences, if any, according to the farm typology, sex, and age of the examined donkeys. The results showed that small strongyles were prevalent in all donkey farms. In all examined farms, most (92–100%) of L3 were identified as cyathostomin species of the genera Cylicocyclus spp. and Cylicostephanus spp. Large strongyles of the genera Strongylus spp. and Triodontophorus spp., were identified at low percentage (8%), only in the single organic farm included in the study. A high agreement was observed between the two different morphometric keys used. No significant differences were found for EPG according to farm typology, and sex and age from the examined donkeys. This is the first report about genera identification of intestinal strongyles infecting donkeys in Tuscany, Italy.

“…An alternative hypothesis should be formulated supposing that C. bronchialis, consistently with other well studied nematodes of the order Strongylida, could have a developmental arrest at the larval stage inside the definitive host [28,29] whose duration is prolonged by the presence of adult parasites that enhance host immunity. If this is the case, the treatment killing adult parasites would produce the observed paradoxical effect [30,31], allowing the rapid development of larval stages in adults.…”

A 6-year-old female goose (Branta hutchinsii) from a group of ornamental exotic geese was found dead due to severe respiratory failure, followed by emission of haemorrhagic sputum and blood clots from the beak and nostrils, and then collapse. At necropsy, the cause of death was attributed to a total of 76 helminth parasites found in the trachea and lungs, then identified as Cyathostoma bronchialis. The flock was initially treated by feed with flubendazole (1200 g/1000 kg/feed) for 7 consecutive days but, at the reappearance of the respiratory symptoms 10 days after, the animals were given fenbendazole by drinking water (300 mg/L) for 7 consecutive days, but at the reappearance of the respiratory symptoms 10 days after, the animals were given fenbendazole via drinking water (300 mg/L) for 7 consecutive days. Despite these treatments, the respiratory symptoms continued to relapse 10–15 days after the end of drug administration. In the literature, there are no data regarding drugs for the treatment of C. bronchialis infestations in geese, and the use of these drugs in exotic birds occurs as “off-label” use. This case study provides information on C. bronchialis life cycle, which is still poorly studied and poorly documented today. In particular, the case provides useful suggestions for evaluating an appropriate protocol for the treatment of C. bronchialis in geese.
