After the use of different Giemsa staining techniques, variations in chromosome banding patterns have often been observed in animal chromosomes. Such staining differences are usually interpreted to indicate that there is more than one type of heterochromatin in many animal chromosomes. Using two differential Giemsa staining techniques we have found different staining patterns in the chromosomes...

Giemsa-stained blood smears are mainly used for microscopic examination to diagnose malaria. However, they may also be subjected to polymerase chain reaction (PCR) to confirm diagnosis or for retrospective studies requiring the analysis of old smears. We investigated the possibility of DNA contamination occurring during automated Giemsa staining or due to the failure to clean the oil-immersion ...

background: the mainstay of diagnosis of relapsing fever (rf) is demonstration of the spirochetes in giemsa-stained thick blood smears, but during non fever periods the bacteria are very scanty and rarely detected in blood smears by mi­cros­copy. this study is aimed to evaluate the sensitivity of different methods developed for detection of low-grade spi­ro­chetemia. methods: animal blood sampl...

This paper describes the overnight Giemsa staining method for detecting mycoplasma infection of cell cultures. This simple method requires no special equipment and has practical application in most cell culture laboratories. This technique has been used conveniently to monitor stock cell cultures for mycoplasma infection over a 12-month period avoiding any contamination.
