DIERESIEKTES IN DIE NOORD-KAAP / ANIMAL DISEASES IN THE NORTHERN CAPE
DIERESIEKTES IN DIE NOORD-KAAP
Verskeie siektes is in die Noord-Kaap aangemeld, volgens die verslag vir die tydperk van 1 April tot 15 Augustus 2024.
Daar was ook skape in die Brandvlei-streek wat positief getoets het vir skaapbrandsiek, terwyl twee aardwolwe positief getoets het in die De Aar-omgewing.
- Skaapbrandsiekte
Altesaam 14 plase in die Calvinia-, Springbok- en De Aar-streke is positief vir skaapbrandsiekte gediagnoseer.
Tans is daar die meeste kommer oor die feit dat sommige boere tydens ‘n uitbreking van die Noord-Kaap na die Wes-Kaap wil verhuis. Veldtoestande is nie goed in die Boesmanland-streek nie en die boere wil na beter weiding in die Wes-Kaap trek.
Die Wes-Kaapse owerheid het toestemming verleen dat sommige diere uit die Noord-Kaap verskuif word nadat hulle behandeling ontvang het.
- Afrika-varkpes
Twee uitbrekings het gedurende Junie en Julie in Kimberley en Griekwastad voorgekom, waarby mak varke en Europese bosvarke betrokke was. Die siekte blyk nou endemies in die Noord-Kaap te wees en word deur vlakvarke na die meeste gebiede versprei waar dit gevind word. Vorige toetse en navorsing is op die tampans wat met die vlakvarke geassosieer word uitgevoer, en alle monsters het positief getoets vir Afrika-varkpes.
- Voëlgriep
Twee plase in die Fraserburg-omgewing het positief getoets vir die voëlgriep H5N6- en H5N8-virus.
Albei plase is onder kwarantyn geplaas. Een plaas sal uitgeslag word wanneer al die voëls gereed is vir slag. Die ander plaas het die meeste van hul voëls weens koue verloor en die laaste groep is op 23 Julie op die plaas uitgeskot.
- Voëltifus (Salmonella gallinarum)
‘n Boer in die Jan Kempdorp-omgewing het gerapporteer dat hoenders positief getoets het vir voëltifus.
Voëltifus word veroorsaak deur Salmonella enterica serotipe Gallinarumbiovar Gallinarum en word gekenmerk deur sterftesyfers by jong voëls soortgelyk aan dié van Salmonella enterica serotipe Gallinarum biovar Pullorum, alhoewel sterftesyfers van S Gallinarum moontlik hoër is by ouer voëls. Jonger voëls is anorekties, swak en depressief, en hulle het wit fekale materiaal wat aan die ventilasie-area geplak is. Besmette voëls kan ook respiratoriese siektes, blindheid of geswelde gewrigte hê, asook ‘n bros en dikwels galgekleurde lewer, met of sonder vergrote milt en niere. Diagnose is gebaseer op isolasie en identifikasie van die organisme en behandeling word nie aanbeveel nie.
- Bek-en-klouseer
Een saak van verdagte diere is in Mei in die Prieska-omgewing ondersoek, en is binne 24 uur opgelos.
Die goeie samewerking tussen die boerderygemeenskap, die departement en die laboratorium om die geaffekteerde diere op te spoor en te toets en om die resultate binne 24 uur uit te kry, moet geloof word.
‘n Terugsporing is gedoen op diere wat van die Noord-Kaap aan die Oos-Kaap gelewer is vir uitvoer na Mauritius, en geen verdagte diere is gevind nie.
‘n Besending van die Noord-Kaap na Mauritius, wat tans onder kwarantyn is, is in die proses om getoets te word.
- Brucellose
‘n Aantal plase is positief in die provinsie, met geen nuwes wat gedurende die laaste kwartaal aangeteken is nie. Die normale prosedure van slag en toetsing word in die verskillende streke voortgesit.
ANIMAL DISEASES IN THE NORTHERN CAPE
Various diseases were reported in the Northern Cape, according to its report for the period from 1 April to 15 August 2024.
There were also sheep in Brandvlei region which tested positive for rabies, while two aardwolves tested positive in the De Aar area.
- Sheep scab
A total of 14 farms in the Calvinia, Springbok and De Aar regions proved to be positive for sheep scab.
The biggest concern currently is the fact that some farmers want to move from the Northern Cape to the Western Cape during an outbreak. Veld conditions is not good in the Bushmanland region and the farmers want to move to better grazing in the Western Cape. Approval was given by the Western Cape to move some animals from the Northern Cape after they received treatment.
- African swine fever
Two outbreaks occurred during June and July in Kimberley and Griekwastad, involving domestic pigs and European Bush pigs. The disease seems now to be endemic to the Northern Cape and is spread by warthogs to most areas where they are found. Previous testing and research were conducted on the tampans associated with the warthogs, and all samples tested positive for African Swine Fever.
- Avian Influenza
Two farms in the Fraserburg area tested positive for the Avian influenza H5N6 and H5N8 virus.
Both farms were quarantined. One farm will be slaughtered out when all the birds are ready for slaughter. The other farm lost most of their birds due to cold and the last group were culled on the farm on 23 July.
- Fowl typhoid (Salmonella gallinarum)
A farmer in the Jan Kempdorp-area reported mortalities tested positive for fowl typhoid.
Fowl typhoid is caused by Salmonella enterica serotype Gallinarumbiovar Gallinarum and is characterised by mortality rates in young birds similar to those of Salmonella enterica serotype Gallinarum biovar Pullorum, although mortality rates of S Gallinarum are possibly higher in older birds. Younger birds are anorectic, weak, and depressed, and they have white faecal material pasted to the vent area. Affected birds may also have respiratory disease, blindness, or swollen joints. Older birds may be pale and dehydrated and have diarrhoea. Lesions in older birds may include a swollen, friable, and often bile-stained liver, with or without necrotic foci; enlarged spleen and kidneys; anaemia; and enteritis. Diagnosis is based on isolation and identification of the organism. The goal for control of fowl typhoid is elimination of the pathogen; therefore, treatment is not recommended.
- Foot and mouth disease (FMD)
One case of suspect animals was investigated in the Prieska area in May, and was resolved within 24 hours.
The good cooperation between the farming community, the department and the laboratory to trace and test the affected animals and to get the results out within 24 hours must be commended
A trace back was done on animals that were supplied from the Northern Cape to the Eastern Cape for export to Mauritius, and no suspect animals were found.
A consignment from the Northern Cape to Mauritius, which is currently under quarantine is in the process of being tested.
- Brucellosis
A number of farms are positive in the province, with no new ones recorded during the last quarter. The normal procedure of slaughter and testing is ongoing in the different regions.
