Pleomorphism is an evolutionary adaptation by which diverse microorganisms maximize their fitness by transitioning between morphologically distinct forms that perform disparate functions in response to the local microenvironment. Cell division is critical for morphotype transition in many pleomorphic bacterial systems. , which causes the emerging disease granulocytic anaplasmosis, is a pleomorphic obligate intracellular bacterium that lives in a pathogen-modified vacuole except for when it is exocytically released for dissemination to naïve cells.

Wolbachia, a widespread endosymbiotic bacterium, profoundly impacts insect hosts by distorting reproduction and population dynamics. Despite extensive laboratory research, its long-term effects on host evolution in nature remain poorly understood, especially the genomic consequences linked to disruptions in sex determination and reproductive processes. We present the first telomere-to-telomere (T2T) genome assembly of the sawfly Analcellicampa danfengensis and the complete genome of its symbiotic Wolbachia.

Background: Leishmaniosis and other canine vector-borne diseases (CVBDs) pose a major risk for veterinary and public health globally, especially where humans and dogs live in close proximity. Although mosquito and tick vectors are abundant in Hong Kong, surveillance for CVBDs has been limited.
Methods: A serological and molecular survey of 158 healthy owned (n = 64) and free-roaming unowned (n = 94) dogs with outdoor access in Hong Kong was performed to determine CVBD prevalence.

Malaria remains a significant infectious disease globally, causing hundreds of thousands of deaths each year. Traditional control methods, such as disease surveillance and mosquito control, along with the development of malaria vaccines, have made strides in reducing the disease's impact, but new control methods are urgently needed. Wolbachia is a natural bacterium that can infect mosquitoes and reduce their ability to transmit diseases.

Vector-borne diseases represent a growing global threat, exposing new populations to previously unknown infectious agents, and posing diagnostic challenges for veterinarians. The aim of this article is to present a clinical case of coinfection with different hemoparasites in a canine with severe ectoparasite infestation and clinical signs of shock. Blood smears and complete necropsy were performed.
