Recently, diagnostic cases of Mycoplasma screening from feline kept rising. In 2018, there were two cases in felines that were positively diagnosed as Mycoplasma co-infection in which one of the two cases was due to mycoplasmosis. Diagnosis of mycoplasmosis was based on isolation and identification using biochemical testing. Mycoplasma was successfully isolated from both cases. Based on the feline death case, the result indicated that Mycoplasma gateae was isolated from the blood-stained trachea sample. In contrast, none was isolated from the lung. As the infection was associated with other microorganisms, this case concluded that the cause of death of the cat was due to Parvovirus with secondary infection of Mycoplasma gateae.

Recently, Fowl Adenovirus (FAdV) cases have been reported in many countries worldwide. FAdV is a contagious agent associated with inclusion body hepatitis (IBH) and hydropericardium syndrome (HPS) in chickens. It belongs to the Aviadenovirus genus of the family Adenoviridae. The virus is classified into five species (A to E) and further divided into 12 serotypes. Depending on the serotypes, they have diverse characteristics of virus that can either be pathogenic or nonpathogenic strain. From the viewpoint of epidemiological as well as vaccine development, it is very important to detect FAdV strains. Previous studies have been conducted on molecular research, but the continuity of this study in Malaysia has been limited. This study aims to identify the serotype classification of five Malaysian FAdV isolates obtained from field outbreaks during 2017-2019. In this study, polymerase chain reactions (PCR) were conducted based on Hexon gene. Results from the nucleotide sequence analysis discovered that the five isolates showed high similarity with FAdV-8b strains. High bootstrap values in phylogenetic analysis supported the clustering of the Malaysian FAdVs isolates into FAdVs species E. Consequently, the result of this study contributed important information on the epidemiology and culminated in the importance of control strategies against FAdV infection in Malaysia.
