WHERE , IN A MEMBER STATE OR REGION THEREOF IN WHICH ALL BOVINE HERDS ARE SUBJECT TO OFFICIAL OPERATIONS TO COMBAT BRUCELLOSIS , NOT MORE THAN 1 % OF BOVINE HERDS ARE INFECTED , IT SHALL BE SUFFICIENT TO CARRY OUT EACH YEAR TWO RING TESTS AT AN INTERVAL OF AT LEAST THREE MONTHS , OR ONE SEROLOGICAL TEST ( SERO-AGGLUTINATION TEST OR BUFFERED BRUCELLA ANTIGEN TEST OR PLASMA-AGGLUTINATION TEST OR PLASMA-RING TEST OR MICRO-AGGLUTINATION TESTS ) .

IN ANNEX A.II.A.2 ( C ) , THE LAST PARAGRAPH IS REPLACED BY THE FOLLOWING : " THE SERO-AGGLUTINATION TESTS REFERRED TO IN 1 ( C ) ( I ) , FIRST INDENT , MAY BE REPLACED BY BUFFERED BRUCELLA ANTIGEN TESTS CARRIED OUT IN ACCORDANCE WITH ANNEX C ( D ) OR MICRO-AGGLUTINATION TESTS CARRIED OUT IN ACCORDANCE WITH ANNEX C ( G ) . " 9 . IN ANNEX C : - PARAGRAPH C IS REPLACED BY THE FOLLOWING : " C . RING TEST 1 . THE RING TEST MUST BE MADE ON THE CONTENTS OF EACH MILK CHURN OR ON THE CONTENTS OF EACH BULK TANK FROM THE FARM . 2 . THE STANDARD ANTIGEN TO BE USED MUST COME FROM ONE OF THE INSTITUTES LISTED IN PARAGRAPH A.9 ( A ) TO ( J ) . IT IS RECOMMENDED THAT THE ANTIGENS SHOULD BE STANDARDIZED ACCORDING TO THE WHO/FAO RECOMMENDATIONS . 3 . THE ANTIGEN MAY BE STAINED ONLY WITH HEMATOXYLIN OR TETRAZOLIUM ; HEMATOXYLIN SHOULD PREFERABLY BE USED . 4 . IF NO PRESERVATION IS USED THEN THE REACTION TEST MUST BE CARRIED OUT BETWEEN 18 AND 24 HOURS OF TAKING THE SAMPLE FROM THE COW . IF MILK IS TO BE TESTED LATER THAN 24 HOURS AFTER SAMPLING , THEN PRESERVATION MUST BE USED , FORMALIN OR MERCURIC CHLORIDE MAY BE USED AS PRESERVATIVES AND IF EITHER OF THESE ARE USED THE TEST MUST BE CARRIED OUT WITHIN THE FOLLOWING 14 DAYS AFTER THE DAY OF SAMPLING . FORMALIN MAY BE ADDED TO GIVE A FINAL CONCENTRATION IN THE MILK SAMPLE OF 0,2 % AND , IN SUCH CASES , THE RATIO BETWEEN THE AMOUNT OF MILK AND THE SOLUTION OF FORMALIN MUST BE AT LEAST 10 TO 1 . A SOLUTION OF MERCURIC CHLORIDE MAY BE USED INSTEAD OF FORMALIN TO GIVE A FINAL CONCENTRATION IN THE MILK OF 0,2 % AND , IN SUCH CASES , THE RATIO BETWEEN THE AMOUNT OF MILK AND THE SOLUTION OF MERCURIC CHLORIDE MUST BE 10 TO 1 . 5 . THE REACTION MUST BE CARRIED OUT USING ONE OF THE FOLLOWING METHODS : - ON A COLUMN OF MILK AT LEAST 25 MM HIGH AND ON A VOLUME OF MILK OF 1 ML TO WHICH 0,03 ML OF ONE OF THE STANDARDIZED STAINED ANTIGENS HAS BEEN ADDED , - ON A COLUMN OF MILK AT LEAST 25 MM HIGH AND ON A VOLUME OF MILK OF 1 ML TO WHICH 0,05 ML OF ONE OF THE STANDARDIZED STAINED ANTIGENS HAS BEEN ADDED , - ON A VOLUME OF MILK OF 8 ML WHICH 0,08 ML OF ONE OF THE STANDARDIZED STAINED ANTIGENS HAS BEEN ADDED , - ON A COLUMN OF MILK AT LEAST 25 MM HIGH AND ON A VOLUME OF MILK OF 2 ML TO WHICH 0,05 ML OF ONE OF THE STANDARDIZED STAINED ANTIGENS HAS BEEN ADDED . 6 .

" ; - A NEW PARAGRAPH G SHALL BE ADDED : " G . MICRO-AGGLUTINATION TEST 1 . DILUENTS ARE MADE UP OF 0,85 % PHYSIOLOGICAL SALINE SOLUTION PHENOLIZED AT 0,5 % . 2 . THE ANTIGEN SHALL BE PREPARED AS DESCRIBED UNDER POINTS 6 , 7 AND 8 OF ANNEX C ( A ) AND SHALL BE TITRATED AS DESCRIBED UNDER POINT 5 OF ANNEX C ( A ) .

THE TEST SHALL BE CARRIED OUT AS FOLLOWS : ( A ) PREDILUTION OF THE SERUM : 0,050 ML OF EACH SERUM TO BE TESTED ARE ADDED TO EACH WELL CONTAINING 0,075 ML OF DILUENT . THE MIXTURES ARE SHAKEN FOR 30 SECONDS . ( B ) GRADUAL SERUM DILUTION : PREPARE AT LEAST THREE DILUTIONS FOR EACH SERUM . TO THIS END FROM THE PREDILUTIONS ( 1 : 2,5 ) ONE TAKES 0,025 ML OF EACH SERUM AND TRANSFERS THEM TO A WELL CONTAINING 0,025 ML OF DILUENT . IN THIS WAY THE FIRST DILUTION REACHES A STRENGTH OF 1 : 5 AND THE FOLLOWING DILUTIONS ARE CARRIED OUT BY DOUBLING . ( C ) ADDITION OF ANTIGEN : 0,025 ML OF ANTIGEN IS ADDED TO EACH WELL CONTAINING THE DIFFERENT SERUM DILUTIONS . AFTER BEING SHAKEN FOR 30 SECONDS THE PLATES ARE CLOSED WITH THEIR RESPECTIVE LIDS AND KEPT AT 37* C FOR 20 TO 24 HOURS IN A HUMIDIFIED ATMOSPHERE . ( D ) READING THE RESULTS : ASSESSMENT OF THE ASPECT OF THE SEDIMENTATION OF THE ANTIGEN IS MADE BY EXAMINING THE BOTTOM OF THE WELL REFLECTED IN A CONCAVE MIRROR PLACED ABOVE IT . IF THERE IS A NEGATIVE REACTION , THE ANTIGEN FORMS A SEDIMENT IN THE FORM OF A COMPACT BUTTON WITH CLEAR EDGES AND HAVING AN INTENSE RED COLOUR . IF THERE IS A POSITIVE REACTION , ON THE OTHER HAND , A DIFFUSED PINK VEIL IS FORMED THAT IS EVENLY DISTRIBUTED . THE DIFFERENT PERCENTAGES OF AGGLUTINATION ARE DETERMINED BY COMPARISON WITH ANTIGEN CHECKS INDICATING 0 , 25 , 50 , 75 AND 100 % AGGLUTINATION . THE TITLE OF EACH SERUM IS EXPRESSED IN INTERNATIONAL UNITS OF AGGLUTINATION PER ML . THERE SHOULD BE INCLUDED IN THE TEST , CONTROLS WITH NEGATIVE AND POSITIVE SERUM DILUTED SO AS TO CONTAIN 30 INTERNATIONAL UNITS OF AGGLUTINATION PER ML . " ARTICLE 2 MEMBER STATES SHALL BRING INTO FORCE THE LAWS , REGULATIONS AND ADMINISTRATIVE PROVISIONS NECESSARY TO COMPLY WITH THIS DIRECTIVE BY 30 SEPTEMBER 1985 . THEY SHALL FORTHWITH INFORM THE COMMISSION THEREOF . ARTICLE 3 THIS DIRECTIVE IS ADDRESSED TO THE MEMBER STATES . DONE AT BRUSSELS , 11 DECEMBER 1984 . FOR THE COUNCIL THE PRESIDENT A . DEASY
