Research Officer, Limerick Regional Veterinary Laboratory, Knockalisheen, Limerick, Ireland</li> </ul></li> </ul> </blockquote> <hr /> <p><br><br></p> <p>Dairy farmers are committed to producing food of the highest standard for consumers. Cellcheck, the National Mastitis Control Programme coordinated by Animal Health Ireland, in association with farmers, milk processors, service providers and Government, have been focusing on reducing somatic cell counts of milk produced in Ireland. Farmers are being encouraged to collect and submit milk samples from cows with cases of clinical and suspect subclinical mastitis for culture and antimicrobial susceptibility testing. Bacteria are responsible for virtually all cases of mastitis; by identifying the agent responsible, important information about possible source of infection may be gathered, enabling a focus for control measures to improve milk quality.</p> <div id="milk-culture-in-rvls" class="section level2"> <h2><span class="header-section-number">7.1</span> Milk Culture in RVLs</h2> <p>All RVLs follow a similar procedure for culturing milk samples. Samples are initially tested for inhibitory substances, such as antibiotics, which can interfere with bacterial growth in the laboratory. At least four different types of agar plates are used to culture each milk sample. Using a sterile swab, a small quantity of milk is spread on to each plate (Figure <a href="bovine-mastitis.html#fig:fmastdos">7.1</a>). These plates are incubated at 37C for 24 <em>hours</em>. If, on inspection, no bacterial growth has occurred at that stage, plates are incubated for a further 24 <em>hours</em>. If there is no change after 48 <em>hours</em> of culture, the result <em>no significant growth</em> is entered.</p> <div class="figure" style="text-align: center"><span id="fig:fmastdos"></span> <img src="images/mastitis2b.jpg" alt="Inoculation of agar plates for culture of a milk sample in Limerick RVL. Photo: Alan Johnson." width="60%" /> <p class="caption"> Figure 7.1: Inoculation of agar plates for culture of a milk sample in Limerick RVL. Photo: Alan Johnson. </p> </div> <p>If bacterial growth is seen on plates, further tests are carried out to identify organisms growing (Figure <a href="bovine-mastitis.html#fig:fmastunox">7.2</a>). If milk sample has been contaminated, cultures usually yield a mixed bacterial growth (Figure <a href="bovine-mastitis.html#fig:fmastseis">7.3</a>); in these cases it can be difficult to identify the significant bacterial species and the result is entered as <em>mixed bacterial growth</em>. Contamination usually occurs when bacteria from sources other than milk inside the udder enter the sample. This could be from skin of the udder, sampler’s hands or from inside of the container itself, if the latter is not sterile.</p> <p>For additonal information, see the <span class="citation">Animal Health Ireland (<a href="#ref-AHIMastitis">2019</a><a href="#ref-AHIMastitis">a</a>)</span> webpage.</p> <table class="table table-striped table-hover table-condensed" style="width: auto !important; margin-left: auto; margin-right: auto;"> <caption> <span id="tab:tmastone">Table 7.1: </span>Relative frequency of mastitis isolates in milk samples submitted to RVLs in 2018 (n= 3413 ). </caption> <thead> <tr> <th style="text-align:left;font-weight: bold;color: pnasbluetext;"> Result </th> <th style="text-align:right;font-weight: bold;color: pnasbluetext;"> No. of cases </th> <th style="text-align:right;font-weight: bold;color: pnasbluetext;"> Percentage </th> </tr> </thead> <tbody> <tr> <td style="text-align:left;font-style: italic;"> Staphylococcus aureus </td> <td style="text-align:right;"> 911 </td> <td style="text-align:right;font-weight: bold;"> 26.7 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> No Significant Growth </td> <td style="text-align:right;"> 591 </td> <td style="text-align:right;font-weight: bold;"> 17.3 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> Other Isolates </td> <td style="text-align:right;"> 578 </td> <td style="text-align:right;font-weight: bold;"> 16.9 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> Contaminated </td> <td style="text-align:right;"> 557 </td> <td style="text-align:right;font-weight: bold;"> 16.3 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> Streptococcus uberis </td> <td style="text-align:right;"> 407 </td> <td style="text-align:right;font-weight: bold;"> 11.9 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> E. coli </td> <td style="text-align:right;"> 193 </td> <td style="text-align:right;font-weight: bold;"> 5.7 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> Streptococcus dysgalactiae </td> <td style="text-align:right;"> 109 </td> <td style="text-align:right;font-weight: bold;"> 3.2 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> Trueperella pyogenes </td> <td style="text-align:right;"> 41 </td> <td style="text-align:right;font-weight: bold;"> 1.2 </td> </tr> <tr> <td style="text-align:left;font-style: italic;"> Bacillus spp. </td> <td style="text-align:right;"> 26 </td> <td style="text-align:right;font-weight: bold;"> 0.8 </td> </tr> </tbody> </table> <div class="figure" style="text-align: center"><span id="fig:fmastunox"></span> <img src="images/mastitis1-small.jpg" alt=" Staphylococcus aureus growing on a blood agar plate.
