Mycoplasma mycoides subsp. mycoides biotype large colony isolates from healthy and diseased goats: prevalence and typing.

Most severe goat mycoplasmosis outbreaks in France are caused by Mycoplasma mycoides subsp. mycoides biotype LC (MmmLC). However, MmmLC can also be recovered from ear canals of healthy goats or from bulk milk collected in herds showing no clinical signs of mycoplasmosis. To improve our understanding of how MmmLC strains are balanced between pathogenic ones and asymptomatically carried ones, descriptive epidemiological data were analysed, together with the genomic fingerprints of isolates generated using pulsed-field gel electrophoresis (PFGE). PGFE analyses were performed with isolates collected from the ear canals of goats or bulk milk in healthy herds, from individual clinical cases in different diseased herds at different times, and within a single herd during a severe outbreak, from various body sites including the ear canals at autopsy. Results showed that each isolate collected in healthy herds yielded a unique and characteristic PFGE profile. Isolates from diseased herds had profiles that were distinct for each outbreak and the group of 41 isolates from a single severe outbreak had 2 predominant PFGE profiles that persisted throughout the outbreak. These data suggest that while several distinct isolates are carried by healthy animals, only a few are responsible for the clinical signs observed within one herd during an outbreak. Whether this reflects differences in virulence between different field strains of MmmLC remains to be demonstrated.

Association studies using random and "candidate" microsatellite loci in two infectious goat diseases.

We established a set of 30 microsatellites of Bovidae origin for use in a biodiversity study in Swiss and Creole goats. Additional microsatellites located within or next to "candidate" genes of interest, such as cytokine genes (IL4, INF-gamma) and MHC class II genes (DRB, DYA) were tested in the caprine species in order to detect possible associations with two infectious caprine diseases. Microsatellite analysis was undertaken using automated sequencers (ABI373 & 3100). In the first study, a total of 82 unrelated Creole goats, 37 resistant and 45 susceptible to Heartwater disease (Cowdriosis) were analysed. In this study, the two microsatellite loci DRBP1 (MHCII) and BOBT24 (IL4) were positively associated with disease susceptibility, demonstrating a corrected P-value of 0.002 and 0.005, respectively. In a second investigation, we tested 36 goats, naturally infected with the nematode parasite Trichostrongylus colubriformis. These animals were divided into a "low" and "high" excreting group on the basis of two independently recorded fecal egg counts. For this nematode resistance study, we detected a significant association of one of the alleles of the microsatellite locus SPS113 with "low" excretion (resistance). The MHC class II locus DYA (P19), was weakly associated with susceptibility in both diseases (Pc = 0.05). In future experiments, we will extend the sample size in order to verify the described associations.

Characterization of lectin-binding lymphocytes in goats with caseous lymphadenitis.

Numbers of lymphoid cells bearing markers for peanut agglutinin, wheat germ agglutinin, and anti-immunoglobulin G in healthy goats and in goats with caseous lymphadenitis were determined by use of immunofluorescent techniques. Results indicated that, when compared with healthy goats, diseased goats had normal numbers of anti-immunoglobulin G-positive cells (B cells), had significantly reduced numbers of peanut agglutinin-positive cells (T cells), and had fewer cells with receptor sites for Lens culinaris agglutinin and concanavalin A. Compared with healthy goats, numbers of peanut agglutinin-positive cells in goats with caseous lymphadenitis indicated that the goats may have had a compromised cell-mediated immunity.

[Care of pregnancy and prevention of lamb diseases in goats].

The breeding of dairy goats has spread in Saxony for over 200 years. Recently the keeping of bigger flocks (30-300 animals) for milk and cheese production has become more common. Within the care of the pregnant she goats the feeding recommendation is a main point of the veterinary herd management. The special performances done by the pregnant animals are discussed. The daily need of energy intake is given with about 11 Megajoule Nettoenergy-lactation as well as the daily need of protein with 230 g. Additionally the minimal daily intake of minerals and vitamins is mentioned. Supervising she goats during lambing and avoiding temperatures lower than 18 degrees C in the stables is considered as necessary to prevent hypoglycemia of the newborn lambs. The enzootic process of Clostridium-perfringens-type-B-infection is discussed in connection with the intake of colostrum and the increasing density of pathogen microorganism during the lambing period.

Management of clinical cases of peste des petits ruminants (PPR) disease in goats.

Clinical cases of Peste des petits ruminants (PPR) disease in goats were treated symptomatically. Broad spectrum antibiotics, intestinal sedatives and fluid therapy were used for the treatment of pneumonia, diarrhoea and the restoration of the body fluid ionic balance. Good feeding and nursing in warm, draught-free pens are necessary. Lemon fruit and Citrus aurantium proved to be effective for the treatment of the orf-like labial scabs. This treatment raised the survival rate of goats by 13.3%.

Abscess disease in goats in the Sudan.

The "abscess disease" was described in naturally infected goats for the first time in Sudan. An anaerobic respiratory deficient staphylococcus was isolated in pure form. The biochemical properties were studied. The disease was successfully reproduced in experimental goats.

Optimal time for vaccination against Peste des petits ruminants (PPR) disease in goats in humid tropical zone in southern Nigeria.

Investigation of the incidence of peste des petits ruminants (PPR) disease in goats revealed seasonality in the natural occurrence of PPR disease in the environment. Tissue culture rinderpest vaccine was shown effective in protecting goats against the disease. The optimal time for vaccinating goats against PPR disease was when the least number of animals were incubating the disease. In the tropical humid zone, as in West Africa, the optimal time for vaccination against the PPR disease is from late November to middle of December.

[Aujeszky's disease in goats (authors transl)].

The small number of cases of Aujeszky's disease in goats referred to in the literature is stressed, and an outbreak in goats causing many deaths is reported. The flock of goats concerned was occasionally housed in a barn during the night in which there also were fattening pigs. The first deaths occurred without previous symptoms, the animals being found dead in the morning. In subsequent cases, symptoms were observed which continued for a few or several hours and consisted in agitation, lying down and rising, screaming plaintively, profuse sweating and, in the terminal stage, spasms and paralysis. Pruritus was not observed in any of the animals. Of the fifteen goats which had been housed in the pig-sty, thirteen died during ten days. In the same period, only one out of forty pigs died, and the others showed anorexia and somnolence for a couple of days but soon recovered. In two goats studied, the virus of Aujeszky's disease was isolated from the central nervous system. It is suggested that, in cases of disease or death in ruminants occurring in the proximity of pigs, there should primarily be a strong suspicion of Aujeszky's disease, regardless of the symptoms observed.

The composition of plasma and interstitial fluid of goats with swelling disease.

Angora goats may develop a characteristic ventral oedema of the subcutaneous tissue which is not unlike the 'wet-carcass syndrome' of sheep. The plasma of oedematous goats shows a lower total protein concentration, a lower colloid osmotic pressure and a lower albumin: globulin ratio than that of normal goats. Similarly, interstitial fluid of oedematous goats has a lower protein concentration, osmolality and colloid osmotic pressure than the fluid from normal but a similar albumin:globulin ratio. These results suggest that, unlike the 'wet-carcass syndrome' of sheep, the most likely explanation for the oedema is hypoproteinaemia which leads to filtration of fluid and an increased capillary permeability.

Border disease of sheep and goats.

Border disease (BD) is a congenital virus disease of sheep and goats first reported in 1959 from the border region of England and Wales. BD virus (BDV) is a pestivirus in the genus Flaviviridae and is closely related to classical swine fever virus and bovine virus diarrhoea virus (BVDV). Nearly all isolates of BDV are non-cytopathogenic (ncp) in cell culture. There are no defined serotypes but pestiviruses isolated from sheep exhibit considerable antigenic diversity and three distinct antigenic groups have been identified. Distribution of the virus is worldwide. Prevalence rates vary in sheep from 5 to 50% between countries and from region-to-region within countries. The disease in goats is rare and characterized by abortion. Clinical signs in sheep include barren ewes, abortions, stillbirths and the birth of small weak lambs. Affected lambs can show tremor, abnormal body conformation and hairy fleeces (so-called 'hairy-shaker' or 'fuzzy' lambs). Vertical transmission plays an important role in the epidemiology of the disease. Infection of fetuses can result in the birth of persistently infected (PI) lambs. These PI lambs are viraemic, antibody negative and constantly excrete virus. The virus spreads from sheep to sheep with PI animals being the most potent source of infection. Apparently healthy PI sheep resulting from congenital infection can be identified by direct detection of viral antigen or viral RNA in leukocytes or by isolation of ncp virus from blood or serum in laboratory cell cultures. Isolation of virus is unreliable in lambs younger than 2 months old that have received colostral antibody. The isolation of virus from tissues of aborted or stillborn lambs is difficult but tissues from PI sheep contain easily detectable levels of virus. To detect the growth of virus in cell cultures it is essential to use an immune-labelling method. Acute infection is usually subclinical and viraemia is transient and difficult to detect. Sheep may also be infected following close contact with cattle excreting the closely related BVDV.

Swainsonine-induced lysosomal storage disease in goats caused by the ingestion of Turbina cordata in Northeastern Brazil.

A disease of the central nervous system in goats was observed in the municipalities of Juazeiro, Casa Nova and Curaça, state of Bahia, and Petrolina, state of Pernambuco, Northeastern Brazil. The disease was produced experimentally in two goats by the administration of dry Turbina cordata mixed with grain. Clinical signs were observed after the ingestion of 62 and 106 g/kg body weight in 28 and 54 days, respectively. The concentration of swainsonine in the plant varied from less than 0.001% to 0.14% (dry weight). Clinical signs of natural and experimental cases included difficulties in standing, ataxia, hypermetria, wide-based stance, intention tremors, spastic paresis mainly in the hind legs, nystagmus, abnormal postural reactions, head tilting, and falling. Diffuse vacuolation of neurons, epithelial cells of pancreas, thyroids, and renal tubules were observed on the histology. From the electron microscopy of Purkinje cells the vacuoles represented dilated lysosomes. These findings demonstrated that T. cordata causes an acquired glycoprotein lysosomal storage disease. The intoxication occurs at least in an area of 27,000 km2 causing severe losses in goats, and some farmers report the disease also in cattle.
