Frankenbacteriosis targeting interactions between pathogen and symbiont to control infection in the tick vector. iScience 2023; 26:106697. [PMID: 37168564 PMCID: PMC10165458 DOI: 10.1016/j.isci.2023.106697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/23/2023] [Accepted: 04/13/2023] [Indexed: 05/13/2023] Open
Abstract
Tick microbiota can be targeted for the control of tick-borne diseases such as human granulocytic anaplasmosis (HGA) caused by model pathogen, Anaplasma phagocytophilum. Frankenbacteriosis is inspired by Frankenstein and defined here as paratransgenesis of tick symbiotic/commensal bacteria to mimic and compete with tick-borne pathogens. Interactions between A. phagocytophilum and symbiotic Sphingomonas identified by metaproteomics analysis in Ixodes scapularis midgut showed competition between both bacteria. Consequently, Sphingomonas was selected for frankenbacteriosis for the control of A. phagocytophilum infection and transmission. The results showed that Franken Sphingomonas producing A. phagocytophilum major surface protein 4 (MSP4) mimic pathogen and reduce infection in ticks by competition and interaction with cell receptor components of infection. Franken Sphingomonas-MSP4 transovarial and trans-stadial transmission suggests that tick larvae with genetically modified Franken Sphingomonas-MSP4 could be produced in the laboratory and released in the field to compete and replace the wildtype populations with associated reduction in pathogen infection/transmission and HGA disease risks.

Res Vet Sci 2020; 129:96-98. [PMID: 31954320 DOI: 10.1016/j.rvsc.2020.01.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 12/09/2019] [Accepted: 01/13/2020] [Indexed: 11/29/2022]
Abstract
Recent studies show that sheep could be considered to be a maintenance host for the causative agents of animal tuberculosis (TB). The performance of diagnostic tests is not well established, and new tests need to be developed for this species. In addition, information about TB prevalence in sheep is scarce. Our objectives were to evaluate a new P22 ELISA for detection of specific antibodies against Mycobacterium tuberculosis Complex (MTC), and to assess the seropositivity in 3998 sheep from herds sampled in TB hotspot areas of northern Atlantic Spain with a low TB prevalence in cattle. Results based on 80 sheep of known infection status suggest excellent sensitivity and specificity (100% and 98%, respectively) even in a M. avium susbsp. paratuberculosis infected flock. The observed TB seroprevalence was 17.96% (698/3998; CI95% 16.31-18.67). Our results indicate that the P22 ELISA may constitute a good option for TB screening at the herd level in sheep, and that sheep are an important host and control programs should be implemented at least in hotspots or when cohabiting with other TB-infected species, i.e. cattle and goats.

Anaplasma phagocytophilum Manipulates Host Cell Apoptosis by Different Mechanisms to Establish Infection. Vet Sci 2016; 3:vetsci3030015. [PMID: 29056724 PMCID: PMC5606577 DOI: 10.3390/vetsci3030015] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 07/11/2016] [Accepted: 07/13/2016] [Indexed: 12/24/2022] Open
Abstract
Anaplasma phagocytophilum is an emerging zoonotic pathogen that causes human and animal granulocytic anaplasmosis and tick-borne fever of ruminants. This obligate intracellular bacterium evolved to use common strategies to establish infection in both vertebrate hosts and tick vectors. Herein, we discuss the different strategies used by the pathogen to modulate cell apoptosis and establish infection in host cells. In vertebrate neutrophils and human promyelocytic cells HL-60, both pro-apoptotic and anti-apoptotic factors have been reported. Tissue-specific differences in tick response to infection and differential regulation of apoptosis pathways have been observed in adult female midguts and salivary glands in response to infection with A. phagocytophilum. In tick midguts, pathogen inhibits apoptosis through the Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway, while in salivary glands, the intrinsic apoptosis pathways is inhibited but tick cells respond with the activation of the extrinsic apoptosis pathway. In Ixodes scapularis ISE6 cells, bacterial infection down-regulates mitochondrial porin and manipulates protein processing in the endoplasmic reticulum and cell glucose metabolism to inhibit apoptosis and facilitate infection, whereas in IRE/CTVM20 tick cells, inhibition of apoptosis appears to be regulated by lower caspase levels. These results suggest that A. phagocytophilum uses different mechanisms to inhibit apoptosis for infection of both vertebrate and invertebrate hosts.
