The eggs enter the venous circulation and migrate through capillaries to the lungs. In white-tailed deer, the nematode inhabits the subarachnoid space of the meninges where it sexually reproduces. The 元 larvae leave the gastropods once in the gastrointestinal tract of the mammalian host and migrate through the body to the spinal cord.

tenuis larvae develop to the 元 stage and are then ingested by grazing ruminants.

The larvae are then picked up by snails and slugs, which act as intermediate hosts. tenuis begins when L1 larvae are shed in the feces of white-tailed deer ( 7, 8). Llama herds have experienced 36% infection rates in a high case year, with a 75% mortality of infected individuals ( 6). For instance, in a high case year up to 22% of a goat herd may become infected, with 44% mortality of infected individuals without treatment ( 5). tenuis infection is a concern for livestock across much of mid to eastern North America where white-tailed deer inhabit. Small ruminants and camelids, hereafter collectively referred to as small ruminants, are aberrant hosts that become infected when they incidentally consume infected intermediate hosts, terrestrial gastropods, while foraging ( 3, 4). tenuis inhabits and reproduces within their central nervous system with rare clinical or population effects. White-tailed deer are the natural, definitive host in which P. It is transmitted from white-tail deer ( Odocoileus virginianus) to susceptible ungulate livestock such as alpacas ( Vicugna pacos), goats ( Capra aegagrus hicus), sheep ( Ovis aries), or llamas ( Lama glama) ( 1, 2). tenuis), commonly known as meningeal worm, is a nematode parasite of wildlife that spills over into domestic livestock, causing significant morbidity and mortality. This study demonstrates seasonal patterns and differences in mortality between alpacas, goats, llamas and sheep and helps us to better understand the epidemiology of P. tenuis-induced mortality rates (range 0–3.9%), but not precipitation. We also observed a positive correlation between summer temperature (range 20.4–22.4☌) and P. tenuis-induced mortality rates varied greatly between years, and have significantly increased over time.

tenuis-induced mortalities exhibited one seasonal peak, around October to December. tenuis-induced mortality rates were highest in llamas (9.91%) and alpacas (5.33%) compared to sheep and goats (<1%), with rates in llamas and alpacas significantly higher than in sheep and goats. tenuis-induced mortality rate of 1.14% in the necropsy submission pool for these species. During the period under examination, 5,617 goats, sheep, llamas and alpacas were necropsied, revealing an overall P. tenuis-induced mortalities in these animals.

tenuis-induced mortality over time and developed temporal models to better understand patterns and drivers of P. We examined archived necropsy reports from small ruminant and camelid mortalities that were submitted, post mortem, to the University of Minnesota Veterinary Diagnostic Laboratory (MNVDL) during 2001–2019 for gross necropsy, histopathology, and pathogen screening. Limited reports exist on the epidemiology of disease caused by the nematode in susceptible livestock. tenuis) is a nematode parasite that can invade the nervous system of small ruminant and camelid species such as alpaca, llama, goats and sheep.
