To overcome limitations of conventional approaches for the identification of Eimeria species of chickens, we have established high resolution electrophoretic procedures using genetic markers in ribosomal DNA. The first and second internal transcribed

Two auxotrophic aro-A mutants of Pasteurella multocida designated PMP1 (serotype 1) and PMP3 (serotype 3) were tested as vaccine candidates to protect chickens against fowl cholera. A reliable intratracheal challenge method was established that resul

An Australian field isolate of Mycoplasma synoviae (MS), 89079/7NS, was exposed to the mutagen N-nitro-N'-methyl-N-nitrosoguanidine. Fifteen clones from the exposed culture were characterized for temperature sensitivity. Four clones labelled B, D, G,

Mycoplasma synoviae (MS) strain MS-H was used in three separate commercial flocks for large-scale evaluation of the safety and efficacy of the vaccine under commercial conditions. MS-H successfully colonized meat and layer-breeders vaccinated by eyed

A temperature-sensitive clone of Mycoplasma synoviae (MS), MS-H, derived from the chemical mutagenesis of the Australian field isolate 86079/7NS, was investigated for efficacy as a live vaccine. Titers of MS-H vaccine ranged between 1.16 x 10(8) and

A temperature-sensitive (ts+) clone derived from the Australian Mycoplasma synoviae (MS) field isolate 86079/7NS was produced by chemical mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine and assessed for safety as a live vaccine. This clone, des

A technique for collecting uterine samples from bitches without the need for surgery was developed. This technique involved visualizing the cervix with a rigid endoscope and passing a catheter through the cervix into the uterus. Samples for microbiol

Vaccination is an option for controlling Mycoplasma gallisepticum or M. synoviae when biosecurity measures fail to prevent the infection of poultry flocks with these mycoplasmas. Both killed vaccines (bacterins) and living vaccines are currently in c

A special chamber was constructed with the goal of controlling the process of aerosol infection of chickens with Mycoplasma gallisepticum (MG). The virulent Australian MG field strain Ap3AS was used in each of three experiments. The response to infec
