Prevalence of traumatic myiasis in Hungary: a questionnaire survey of veterinarians.
Abstract: Veterinarians in Hungary were asked to complete a questionnaire on traumatic myiasis; of the 664 veterinarians contacted, 247 replied (37.2 per cent) and of these 209 (84.6 per cent) reported myiasis to be a problem among the livestock they treated. Infestation levels of > 10 per cent of animals were reported in sheep, cattle and horses. The myiasis season lasted from March to November with most cases reported in July and August. Significantly more respondents reported that fly larvae were present deep in wounds rather than superficially, consistent with infestations due to the obligate parasite Wohlfahrtia magnifica (Diptera: Sarcophagidae). Frequent inspections and the treatment of infested animals were reported by 64.1 per cent of respondents as contributing to the economic impact of traumatic myiasis, and approximately half of the respondents (51.4 per cent) reported that inspections and treatments were carried out at least weekly during the summer. The most common form of treatment was the manual removal of larvae followed by topical application of insecticides, particularly organophosphates. More than half of the respondents (56.6 per cent) reported that there had been no change in the importance of myiasis over the last five to 10 years, but of those who reported a change, more reported an increase (28.3 per cent) than a decrease (15.2 per cent).

The research surveys the prevalence of traumatic myiasis, a parasitic infestation, amongst livestock in Hungary based on responses from veterinarians. It found that over 84% of the veterinarians reported significant infestation levels in sheep, cattle, and horses, especially during summer months, and stated that frequent treatment and inspections had a significant economic impact.
Research Methodology and Findings
- The research relied on a questionnaire survey completed by veterinarians across Hungary, reaching out to 664 veterinarians of whom 37.2 percent, or 247 veterinarians, responded.
- A significant majority i.e., 84.6% of the responding veterinaries reported traumatic myiasis, a parasitic infestation caused by the larvae of certain fly species, as a persistent problem among the livestock they were treating.
- There were high infestation levels reported, with more than 10 percent of livestock including sheep, cattle, and horses being affected.
Infestation Timeline and Treatment
- The timing of myiasis seemed to follow a seasonal pattern, lasting from March to November and peaking in July and August.
- Most respondents noted that the larvae were typically found deep within wounds, indicative of Wohlfahrtia magnifica, a species of blowfly from the family Sarcophagidae, which prefers to lay its eggs in deep tissue.
- Livestock required frequent inspections and treatment to manage infestation; about 64.1 percent of respondents recognized this as contributing to the economic strain of managing traumatic myiasis.
- Roughly half of the veterinarians (51.4 percent) reported conducting inspections and treatments at least once a week during the summer months.
- The most common method of treatment was manually removing the larvae and then applying a topical insecticide, often an organophosphate.
Changing Trends in Traumatic Myiasis
- Over half of the respondents noticed no significant change in the prevalence of myiasis during the last 5 to 10 years.
- However, out of those who did report a change, more observed an increase in the incidence of myiasis (28.3 percent) than a decrease (15.2 percent).
