What is meningeal worm Meningeal Worm (Parelaphostrongylus tenuis), and what should send you to a veterinarian straight away?

A parasite of areas shared with white-tailed deer; camelids are atypical hosts and the nervous system is damaged after infection. It presents with an unsteady gait, hindlimb weakness, lameness, and may progress to an inability to stand. The direction of handling is that it is an emergency, veterinary intervention is needed as early as possible, and the prognosis varies with how far it has progressed. This row belongs to the category in the original chapter that needs prompt attention; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or dosages are given here.

What is choke Choke (oesophageal obstruction), and what should send you to a veterinarian straight away?

Swallowing pelleted feed too fast, or without chewing it enough. It presents with drooling, abnormal extension of the neck and obvious distress. The direction of handling is that it is an emergency requiring immediate veterinary care. This row belongs to the category in the original chapter that needs prompt attention; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or dosages are given here.

What is heat stress Heat Stress, and what should send you to a veterinarian straight away?

Native to a cool climate, the alpaca has low tolerance of hot and humid conditions. It presents with open-mouth panting, drooling, a sharp drop in activity, and may lead to collapse. The direction of handling is that it is an emergency: cool the animal immediately and seek veterinary care. This row belongs to the category in the original chapter that needs prompt attention; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or dosages are given here.

Ten common diseases of the alpaca (Vicugna pacos) gathered into one table: meningeal worm Meningeal Worm (*Parelaphostrongylus tenuis*), choke Choke (oesophageal obstruction), heat stress Heat Stress, vitamin D deficiency-related skeletal disease in crias, gastrointestinal parasites (general nematodes), dental malocclusion Dental Malocclusion, C3 ulceration C3 Ulceration (the third-compartment ulceration characteristic of camelids), enterotoxaemia Enterotoxemia, mastitis Mastitis, and trauma from fighting Trauma (seen especially between uncastrated males). Each row lists the cause, signs, examination, treatment direction and prevention, with the treatment direction giving categories only and no dosages. It suits the moment you take on a new group of animals, or when you notice something wrong and want to narrow down the direction first.

Alpacas｜10 Common Diseases (cause → signs → examination → treatment direction → prevention)

This content is compiled from the disease table for the alpaca (Vicugna pacos) in the farm animals and horses chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.

#	Disease	Cause	Signs	Examination	Treatment direction	Prevention
1	Meningeal worm Meningeal Worm (Parelaphostrongylus tenuis)	A parasite of areas shared with white-tailed deer; camelids are atypical hosts and the nervous system is damaged after infection	Unsteady gait, hindlimb weakness, lameness, may progress to an inability to stand	Clinical neurological assessment, cerebrospinal fluid examination	An emergency; veterinary intervention is needed as early as possible and the prognosis varies with how far it has progressed	Follow the veterinarian-advised preventive deworming programme in endemic areas, and manage the grazing environment to reduce overlap with deer
2	Choke Choke (oesophageal obstruction)	Swallowing pelleted feed too fast, or without chewing it enough	Drooling, abnormal extension of the neck, obvious distress	Clinical inspection, endoscopy where necessary	An emergency, requiring immediate veterinary care	Feed small amounts more often, and use designs that slow the rate of eating
3	Heat stress Heat Stress	Native to a cool climate, with low tolerance of hot and humid conditions	Open-mouth panting, drooling, a sharp drop in activity, may lead to collapse	Clinical assessment, body temperature measurement	An emergency; cool the animal immediately and seek veterinary care	Shade, plentiful drinking water, summer shearing, and avoiding activity during the hottest hours
4	Vitamin D deficiency-related skeletal disease in crias	Insufficient sunlight from indoor housing at high latitudes or over winter, together with inappropriate mineral supplementation	Abnormal growth, skeletal deformity, reduced activity	Blood vitamin D／mineral testing	A supplementation plan assessed by a veterinarian or nutritionist	Plan mineral supplementation according to local soil conditions
5	Gastrointestinal parasites (general nematodes)	Infection pressure from the grazing environment	Wasting, poor fleece, diarrhoea	Faecal egg count	Anthelmintics require veterinary prescription	Strategic deworming, rotational grazing management
6	Dental malocclusion Dental Malocclusion	Congenital, or abnormal wear	Difficulty chewing, weight loss	Oral examination	Veterinary or professional dental correction is required	Regular oral examination
7	C3 ulceration C3 Ulceration (the third-compartment ulceration characteristic of camelids)	Associated with stress and inappropriate dietary management	Reduced appetite, tooth grinding, abdominal discomfort	Veterinary assessment required	Medication requires prescription	Reduce sources of stress, dietary management
8	Enterotoxaemia Enterotoxemia	The same mechanism as in sheep (see column 7 of (E))	Sudden death, or convulsions and abdominal pain	Confirmed by pathological examination	The prognosis in acute cases is poor	Vaccination, avoiding abrupt feed changes
9	Mastitis Mastitis	Bacterial infection (in lactating dams)	Redness and swelling of the udder, abnormalities in the nursing cria	Veterinary assessment required	Antibiotics require prescription	Hygiene management
10	Trauma／fighting injury Trauma (seen especially between uncastrated males)	Fighting between uncastrated males, with bite wounds from the "fighting teeth" (canines)	Traumatic bleeding, lameness	Visual inspection	Wound management requires veterinary assessment	Castration management at the appropriate age, and housing uncastrated males in separate groups

The 10 rows above are copied cell by cell from the original encyclopedia chapter, without rewriting or condensing; the treatment direction gives categories only, never drug names or dosages, and medication must be prescribed by a veterinarian.
