Curd is formed when milk is acidified - either by adding an acid such as vinegar, or by contamination by some bacteria like lactobacilli, which lower the pH of milk. This causes the milk proteins to coagulate i.e. milk doesn't stay an emulsion anymore, but separates into solid and liquid parts. However, in this whole process, the nutrients in the milk, viz. the calcium & other mineral content, the sugar content and most of the fat content (if the milk wasn't skimmed) stays the same. So it can still harbour a variety of microorganisms - provided they can tolerate the low pH. Besides, wherever there are bacteria present, viruses known as bacteriophages are also found. These depend on the bacteria for their "sustenance".
