“…In addition to the present results, recent studies in the REPSA in Mexico City have reported other vector‐borne pathogens in feral dogs, such as Ehrlichia canis and Bartonella vinsonii berkhoffii (Arenas et al., 2019) indicating a relatively complex eco‐epidemiology of vector‐borne diseases in this region. However, future research is needed in order to understand the ecology dynamics of R. typhi and whether feral dogs, cats and peridomestic rodents have a key role in the transmission of the bacteria in the surrounding areas of Mexico City.…”

Murine typhus, a neglected rickettsiosis caused by Rickettsia typhi, is a common disease in several Latin-American countries. The sylvatic life cycle of R. typhi encompasses the presence of several wild mammals, particularly opossums of the genus Didelphis and their associated fleas. Due to the colonization of wild environments by human populations, the increase in contact with opossum fleas has generated the presence of urban outbreaks of typhus. For this reason, the aim of our study was to identify the presence and diversity of Rickettsia sp. in fleas collected from opossums of an urban reserve in Mexico City. Opossums were captured from February to September 2017. For the detection of Rickettsia DNA, fragments of 800 bp of the citrate synthase (gltA) and the outer membrane protein B (ompB) were amplified. A total of 141 fleas (111 ♀, 30 ♂) of a single species (Ctenocephalides felis felis) were recovered from 31 Didelphis virginiana. Rickettsia DNA was detected in 17.7% (25/141) of the analysed fleas, recovered from seven infested opossums. The Maximum likelihood of sequences exhibited an identity of 99%-100% with sequences of R. typhi from southern United States. This work represents the first record of R. typhi in fleas from opossums in Mexico.

“…berkhoffii in three (15.8%) of 19 dogs, although not B. henselae (Arenas et al . ). These data suggest that exposure to various Bartonella species in dogs in Mexico may be dependent upon which environment they are from and which Bartonella pathogens are infecting fleas parasitizing these dogs.…”

Bartonella sp. infection is quite common in free‐roaming dogs in many tropical countries. However, limited information is available of the presence of these pathogens in Mexico. The present study looked at prevalence of Bartonella exposure and/or infection in dogs and their fleas in Central Mexico. Blood samples were collected from 31 stray dogs in August 2014 at the municipal pound, Tulancingo, Mexico, as well as fleas on 26 of them. Bartonella seropositivity was 46.9%, including 35.5% for Bartonella henselae, 45% for Bartonella clarridgeiae and 32.2% for Bartonella vinsonii subsp. berkhoffii. Three (9.7%) dogs were polymerase chain reaction (PCR) positive for the Bartonella gltA gene. Partial sequencing of that gene revealed that these three dogs were infected with B. henselae. In total, 86 fleas were collected from 26 dogs (range 1–9 fleas per dog), including 52 Ctenocephalides felis and 34 Ctenocephalides canis. Of 40 pools of fleas (20 pools of C. canis and 20 pools of C. felis), five (12.5%) were PCR positive for the Bartonella sp. gltA gene, including three C. canis pools (five fleas) and two C. felis pools (three fleas). All sequences showed 99.25% to 100% homology with B. henselae Houston I.

“…De igual forma, se identificaron como variables asociadas a la infección la raza y la edad (animales mayores a un año) (Reyes-Clímaco et al 2020). Arenas et al (2019) detectaron agentes patógenos transmitidos por garrapatas (Anaplasma, Bartonella, Ehrlichia, Mycoplasma y Rickettsia) en la reserva ecológica El Pedregal de San Ángel, ubicada al sur de la Ciudad de México, dentro de la Universidad Nacional Autónoma de México (UNAM). La temperatura media anual y precipitación de ésta, es de 15°C y 700-900 mm, respectivamente.…”
