20% of the goats in India are positive for CAE
These researchers called it Maedi Visna but it is the same virus and can affect sheep or goats

CAE (also called the small ruminant lentivirus) is endangering rare goat breeds of Southern Italy.

According to the Domestic Animal Diversity Information System (DAD-IS) of the FAO, Italy has one of the largest numbers of local small ruminant breeds among European countries. In Southern Italy, namely the Campania Region, Bagnolese and Laticauda sheep breeds and Cilentana goat breeds are considere...

91% of goat herds in Luzon, the Philippines have 1 or more positive CAE goats . Over 31% of goats tested were positive. We need to have control programs in all countries.

Caprine arthritis encephalitis (CAE) is a worldwide economically important disease of small ruminants particularly goats. CAE has been considered to be an emerging/re-emerging disease of goats and a notifiable disease in the Philippines. In this study, a nested-PCR method to detect CAE virus (CAEv)....

Goat kids need colostrum but what is best?- fresh or frozen caprine colostrum (if CAE and JD are not a concern), heat-treated caprine colostrum, bovine colostrum (if Johne's free) or a commercial colostrum replacement product ?

The effect of the subclinical small ruminant lentivirus infection of female goats on the growth of kids - PubMed . Kids fed cow's colostrum (hopefully Johne's free) and powdered milk replacer and separated from their CAE positive dams, grew as well as other kids.

A longitudinal observational study was carried out to evaluate the influence of prenatal exposure to small ruminant lentivirus(SRLV)-infected does on the body weight (BWT) of young kids. The study was carried out in years 2001-2017 in the research dairy goat herd. Goats in the herd were regularly se...

CAE in New Zealand
An extract from this reference = "The disease (CAE) is widespread in the New Zealand goat population, although extensive testing has reduced the incidence in commercial dairy goats." What a pity - I remember when it was first detected from Australian imported goats . This was a lost opportunity to eradicate it. Page 37

Unusual clinical presentation from New Zealand
Two adult goats developed chronic
diarrhoea on a property in Hauraki.
Johne’s disease was suspected and one
animal was subsequently euthanased.
This goat’s stifle joints (knees) were
swollen and lymphatics in the neck
were nodular. Serum samples from
Quarterly report of diagnostic cases: January to March 2024
Surveillance 51 (2) 202435
the two goats tested negative for
Johne’s disease on ELISA; however, the
samples tested positive for the caprine
arthritis-encephalitis (CAE) virus
antibody ELISA. Caprine arthritis-
encephalitis is a widespread disease in
goats that affects all breeds and ages
of goats and persists throughout the
animal’s life (Oliver, 1982; Oliver et
al., 1983). The disease can progress
over months to years and is usually
observed clinically after two years of
age. Bilateral or unilateral swelling of
the leg joints is common. Other signs
include weight loss and/or impaired
milk production (Greenwood, 1995).
Transmission is typically through the
ingestion of virus-infected colostrum
by goat kids, but lateral and vertical
transmission through close contact
with infected animals and from the
reproductive tract of infected females
are also thought to occur (Adams et al.,
1983; Hasegawa et al., 2017).

CAE in wild deer
A new reference just published has found 3 positives out of 314 samples from different wild deer species in Poland. Interesting to speculate on how this happened as the CAE virus is thought not to last long on pastures. So possible to jump species into deer so commercial deer farmers need to be aware of this.

Small ruminant lentiviruses (SRLVs) are widespread and infect goats and sheep. Several reports also suggest that SRLVs can infect wild ruminants. The presence of specific antibodies against SRLVs has been identified in wild ruminants from Poland, but no studies have been conducted to detect proviral...

An outbreak of small ruminant lentivirus (CAE) in a Swedish dairy goat herd with a long history of respiratory disease. Lung forms can happen but are rarer than the arthritis form -but this dairy goat herd mainly had lung problems. All confirmed by testing.

It is a lot harder to eradicate Johne's disease than CAE as the causal organism last months not days on pasture. Norway has actually done both .

While paratuberculosis control has been studied for over a century, knowledge gaps still exist regarding the uptake and efficacy of control programmes.

CAE talks
Remember that I talk about CAE for free to your goat club or event. You just have to provide an COVID Safe outdoor venue and get me there or arrange a Zoom time. Email me [email protected]. Raising awareness helps control and hopefully then eradicate CAE.

Please fill out this survey to help gather evidence for better acces to pain medication for goats
The management of pain during and after common animal husbandry practices (such as disbudding and castration) has been shown to improve productivity in small ruminants and is part of the Australian Industry Welfare Standards and Guidelines for Goats. Unfortunately, the goat industry currently doesn’t have direct access to pain management products (such as meloxicam and lignocaine) due to a lack of registration for their use in goats. We are working on behalf of the Goat Industry Council of Australia (GICA), Meat and Livestock Australia (MLA), and Animal Health Australia (AHA) to try to change that, but also need your help to understand the needs of the industry.
https://www.surveymonkey.com/r/W72PKW9
If you have goats (regardless of number), please take the 10-15mins to complete the survey in this link. Your information will be kept confidential and only aggregated data will be provided to the above organisations. Thank you in advance!

Serbia did its first serological survey of CAE in goats (and small ruminant lentivirus in sheep). Very high levels were found especially in bucks. Read full article here

Small Ruminant Lentivirus causes a chronic lifelong, multisystemic diseases in sheep and goats with or without clinical manifestation. Maedi-visna virus (MVV) and Caprine arthritis encephalitis virus (CAEV) are often considered together as small ruminants lentivirus (SRLV) due to their phylogenetic....

Don't forget to blood test your bucks. They are more likely to be positive if have high levels of carrier does in the herd. Is this cause or effect? I think effect from bucks sniffing and licking does' vaginal mucous.

Maedi Visna is the same virus as CAE - both now called the Small Ruminant Lentivirus. If the goat industry doesn't promote CAE control in dairy goats then it will spread and causes the same problems as in Scottish sheep

MV is maedi visna or the sheep form of the small ruminant lentivirus so the same as CAE. You should listen to this podcast.

In this ‘On The Hoof’ podcast for vets in practice (equally useful for farmer too!) Alison Braddock, Marketing and Business Development Manager, chats to Dave Wilson, Health Schemes Veterinary Manager about what to do when a client’s animal tests positive for MV following a routine periodic blood test in the Premium Sheep and Goat Health Schemes. The podcast touches on how MV acts in the flock and the disease prevalence in GB. It also looks at the testing methodology and options to tackle infection and how to cope with a larger flock breakdown. http://tinyurl.com/26rbb84j

This is why we say not to take blood samples until a month after vaccination. I often vaccinate immediately after taking the blood sample. Goat owners in the UK and EU have bluetongue outbreaks so should take special note of this article - Interference of vaccination against bluetongue virus serotypes 1 and 8 with serological diagnosis of small-ruminant lentivirus infection.

The effects of the recent vaccinations against bluetongue virus serotype 1 (BTV-1) and BTV-8 in Europe on the reliability of enzyme-linked immunosorbent assays (ELISAs) currently used for diagnosis of small-ruminant lentivirus (SRLV) infection were examined. Primary vaccination against BTV-8 in goat...
