An epidemiological study of Babesia canis in dogs in Nigeria was performed. Four hundred blood samples collected from dogs in Nigeria were investigated using nested PCR and sequence analysis. On nested PCR screening, nine samples (2.3%) produced a band corresponding to a 698-bp fragment indicative of B. canis infection. Sequence analysis of the PCR products identified eight samples (2.0%) as B. canis rossi and the ninth (0.3%) as B. canis vogeli. This is the first report of the prevalence of B. canis rossi and B. canis vogeli in dogs in Nigeria.

Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

In a previously reported equilibrium study of the reaction of 5,5'-dithiobis(2-nitrobenzoate), DTNB, with various carbonmonoxyhemoglobins over the pH range 5.6 to 9, we obtained contradictory results on the influence of the allosteric effector inositol hexakisphosphate (inositol-P) on the DTNB reaction. For this reason, we replaced the carbonmonoxyhemoglobins with oxyhemoglobins and investigated the effect of inositol-P on the equilibrium and of their reactions with DTNB over the same pH range.

Article Synopsis
- Cholangiocarcinomas are malignant tumors originating from bile duct epithelium and are commonly found in dogs, particularly exotic breeds aged 2-5 years.
- The study analyzed five cases reported from 2012 to 2021, focusing on clinical signs, blood tests, and postmortem examinations to improve diagnosis techniques.
- Findings consistently included severe malnutrition, jaundice, anemia, and characteristic neoplastic cell clusters, although early diagnosis is challenging due to a lack of specific early-stage symptoms.
Rabies epidemiology in Malaysia (2015-2023): A cross-sectional insights and strategies for control.

Background: Malaysia currently faces significant challenges in controlling the spread of dog-mediated human rabies, as evidenced by recurrent outbreaks in newly affected areas and increasing human fatalities.
Materials And Methods: A cross-sectional study was conducted to analyse surveillance data from 2015 to 2023 to examine the epidemiological characteristics of rabies in Malaysia. Data from multiple sources were used, and descriptive statistics, incidence rates, and reproductive numbers were calculated.
Genomic analysis of multi-drug resistant coagulase-negative staphylococci from healthy humans and animals revealed unusual mechanisms of resistance and CRISPR-Cas system.

Article Synopsis
- - The study focuses on the genomic analysis of 26 multidrug-resistant coagulase-negative staphylococci (MDR-CoNS) sourced from various animals and humans in Spain, highlighting their potential as a reservoir for antimicrobial resistance (AMR) mechanisms.
- - Researchers found various AMR genes in the MDR-CoNS, including some unusual ones, and noted that a significant percentage of the strains also carried genes related to adherence and immune evasion, along with resistance to biocides and heavy metals.
- - Phylogenetic analysis revealed that certain strains, particularly S. borealis, were highly related to those found in pigs, indicating a possible transmission link, and emphasized the global connections of S. epidermidis lineages.*
