Background: Actinomyces species are part of mucosal surfaces of oral cavity, gastrointestinal and genital tracts. When these mucosal surfaces disrupt, Actinomyces become pathogen and cause infection. Eosinophil leucocytes participate in host defense against helminthic infestation and they generally play a role in asthma and allergy. However, the role of eosinophil leucocytes in host defense against bacteria is conflicting.
Aim: To determine whether there is a relationship between Actinomyces-like organisms (ALOs) and eosinophil leucocytes at light microscopic level.
Materials And Methods: Cervicovaginal samples obtained from 200 patients were examined by both Pap smear microscopy and anaerobic culturing. Since the results obtained by these methods were not concordant for diagnosis of genital Actinomyces, 6 of 200 patients (3%) diagnosed with ALOs by Pap smear microscopy became the study group. Patients without any infectious agents (n=134) were the control group. Statistical analyses were conducted with χ(2) test using SPSS program.
Results: The study and control groups were compared statistically in view of the presence of eosinophil leucocytes and it was found that there was a significant correlation between the presence of ALOs and eosinophil leucocytes (P<0.05). Abundant polymorphonuclear leucocytes (PMNLs) and macrophages were also detected in the study group.
Conclusion: This study implies that eosinophil leucocytes might have a role in host defense against Actinomyces in addition to PMNLs and macrophages.

Interferon γ-induced protein 10 kDa (IP-10) or C-X-C motif chemokine 10 (CXCL10) is produced and secreted from specific leukocytes such as neutrophils, eosinophils, and monocytes, which play key roles in the immune response to Plasmodium infections. This systematic review aimed to collate and critically appraise the current evidence on IP-10 levels in malaria patients. It provided insights into its role in malaria pathogenesis and potential as a biomarker for Plasmodium infections and disease severity.

Department for Clinical Sciences, University of Sarajevo-Veterinary Faculty, Sarajevo, Bosnia and Herzegovina.
Background: Age-related changes in physiological parameters are crucial in understanding the health and performance of working dogs, particularly those in demanding roles such as military and law enforcement. However, limited research exists on how aging affects the hematological and biochemical health of these dogs.
Aim: This study aims to characterize age-related variations in hematological and biochemical parameters in working Belgian Shepherd dogs to provide insights that could inform health management strategies for these animals.

Study Objectives: The complete blood count (CBC) is one of the most commonly ordered blood tests with a large range of reference values that does not consider time of day for interpretation. Our objective was to systematically review this topic to report on peak and trough timing of CBC values.
Methods: A systematic search was performed for studies evaluating any component of the CBC with at least three collections over 24 hours.

Introduction: Bullous pemphigoid (BP) and prurigo nodularis (PN) are chronic pruritic skin diseases that severely impact patients' quality of life. Despite the widespread attention these two diseases have garnered within the dermatological field, the specific pathogenesis, particularly the molecular mechanisms underlying the pruritus, remains largely unclear. Limited clinical sequencing studies focusing on BP and PN have hindered the identification of pathological mechanisms and the exploration of effective treatment strategies.
