Development and validation of a real-time SYBR green PCR method for the detection and differentiation of <i>Babesia</i> and <i>Theileria</i> species (Apicomplexa: Piroplasmida) in hard ticks and cattle blood from Thailand <span class="so-article-trans-title" dir="auto"> Translated title: DĂ©veloppement et validation d’une mĂ©thode de PCR SYBR Green en temps rĂ©el pour la dĂ©tection et la diffĂ©renciation des espèces de <i>Babesia</i> et de <i>Theileria</i> (Apicomplexa : Piroplasmida) dans des tiques dures et le sang des bovins en ThaĂŻlande </span>

<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d4506037e283">Tick-borne pathogens, particularly <i>Babesia</i> and <i>Theileria</i> species, are major threats to cattle production, causing economically significant diseases such as babesiosis and theileriosis. In this study, a real-time SYBR Green PCR assay was developed to detect <i>Babesia</i> and <i>Theileria</i> species in hard ticks ( <i>N</i> = 65) and cattle blood samples ( <i>N</i> = 143) from Thailand. Using primers targeting the mitochondrial cytochrome b gene for <i>Babesia</i> and the nuclear 18S rRNA gene for <i>Theileria</i>, the assay measured specific melting temperatures (Tm) for each species. The results showed distinct Tm values for <i>Babesia bigemina</i> (74.38 Â± 0.04 Â°C), <i>Babesia bovis</i> (75.7 Â± 0.06 Â°C), <i>Theileria orientalis</i> (74.61 Â± 0.03 Â°C), <i>Theileria sinensis</i> (75.84 Â± 0.03 Â°C), and <i>Theileria annulata</i> (74.06 Â± 0.03 Â°C). The assay demonstrated high specificity, with a cutoff cycle threshold of < 35 cycles and a minimum detectable concentration of 10 copies/ÎĽL. Significant species differences in melting curves were confirmed using Tukey’s HSD test ( <i>p</i> < 0.05). <i>Theileria orientalis</i> was detected in 8.4% of cattle blood samples, while <i>T. sinensis</i> was found in 25.9%, and <i>B. bigemina</i> in 0.7%. <i>Theileria orientalis</i> was also detected in 7.7% of tick samples, <i>T. sinensis</i> in 16.9%, and <i>B. bigemina</i> in 6.1%. The assay returned negative results for all non-target blood and tissue pathogens tested for specificity. This robust, high-throughput assay is highly effective for monitoring <i>Babesia</i> and <i>Theileria</i> infections, facilitating close surveillance and intervention efforts against tick-borne diseases in cattle. </p><p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d4506037e355">Les agents pathogènes transmis par les tiques, en particulier les espèces de <i>Babesia</i> et de <i>Theileria</i>, constituent une menace majeure pour la production bovine, provoquant des maladies Ă©conomiquement importantes telles que la babĂ©siose et la theilĂ©riose. Dans cette Ă©tude, un test de PCR SYBR Green en temps rĂ©el a Ă©tĂ© dĂ©veloppĂ© pour dĂ©tecter les espèces de <i>Babesia</i> et de <i>Theileria</i> dans des tiques dures ( <i>N</i> = 65) et des Ă©chantillons de sang de bovins ( <i>N</i> = 143) en ThaĂŻlande. Ă€ l’aide d’amorces ciblant le gène du cytochrome b mitochondrial pour <i>Babesia</i> et le gène de l’ARNr 18S nuclĂ©aire pour <i>Theileria</i>, le test a mesurĂ© les tempĂ©ratures de fusion (Tm) spĂ©cifiques de chaque espèce. Les rĂ©sultats ont montrĂ© des valeurs de Tm distinctes pour <i>Babesia bigemina</i> (74,38 Â± 0,04 Â°C), <i>Babesia bovis</i> (75,7 Â± 0,06 Â°C), <i>Theileria orientalis</i> (74,61 Â± 0,03 Â°C), <i>Theileria sinensis</i> (75,84 Â± 0,03 Â°C) et <i>Theileria annulata</i> (74,06 Â± 0,03 Â°C). Le test a dĂ©montrĂ© une spĂ©cificitĂ© Ă©levĂ©e, avec un seuil de cycle de coupure < 35 cycles et une concentration minimale dĂ©tectable de 10 copies/ÎĽL. Les diffĂ©rences significatives entre les espèces dans les courbes de fusion ont Ă©tĂ© confirmĂ©es Ă  l’aide du test HSD de Tukey ( <i>p</i> < 0,05). <i>Theileria orientalis</i> a Ă©tĂ© dĂ©tectĂ© dans 8,4 % des Ă©chantillons de sang de bovins, tandis que <i>T. sinensis</i> a Ă©tĂ© trouvĂ© dans 25,9 % et <i>B. bigemina</i> dans 0,7 %. <i>Theileria orientalis</i> a Ă©galement Ă©tĂ© dĂ©tectĂ©e dans 7,7 % des Ă©chantillons de tiques, <i>T. sinensis</i> dans 16,9 % et <i>B. bigemina</i> dans 6,1 %. Le test a donnĂ© des rĂ©sultats nĂ©gatifs pour tous les agents pathogènes sanguins et tissulaires non ciblĂ©s testĂ©s pour la spĂ©cificitĂ©. Ce test robuste et Ă  haut dĂ©bit est très efficace pour le suivi des infections Ă  <i>Babesia</i> et <i>Theileria</i>, facilitant ainsi la surveillance Ă©troite et les interventions contre les maladies transmises par les tiques chez les bovins. </p>

I have no joint pain! In fact, I haven't had any since... I don't know... summer-ish.
I want to stay on this herbal medicine forever to avoid another relapse. No #BrainFog either! And, I am building strength! I am baking cookies! I am singing our praises to the earth, sun, and moon. #Lyme, #Bartonella, #Babesia, #HerbalMedicine #JapaneseKnotweed, #LymeDisease, #ChronicIllness, #wellBeing, #Yoga, #SidaAcuta
#Bartonella is kicking my butt -- again. I thought I was over #LymeDisease, #Babesia, and other #Lyme coinfections. This week, I am in pain. I am hopeful that #Biocidin, which I started yesterday, will make me feel better soon. Everything is temporary: we are never stuck. I am healing already. Please cheer me on.

It’s Tick Time! What To Know About The Growing Risk Of Infections From Ticks

Ticks are increasingly abundant now. They can cause so many different symptoms and infections. Here's what to look for.

Time to finally #introduce myself! I’m currently a #postdoc studying #trypanosome #parasites at Brown. I’m working on understanding T. cruzi (which causes Chagas’ disease) from multiple perspectives. I previously did my #phd on #babesia at the at Harvard (HSPH), and even before that I worked on #nematode parasites! Outside science, I am an #artist and I love #painting. I also work on initiatives advocating for support of #mentalhealth and ending stigma around #mentalillness
